This month we are doing things slightly differently. We are asking the LLM’s to answer several questions linked to a scenario to see how they respond to complex scenarios over time. The scenario and questions we fed the LLMs is as below:

Scenario: Mary’s Little Lamb Co. Ltd (“Mary’s”) engages Container Lines Ltd to transport two reefer containers (R1 and R2) from Mary’s farm in Hamilton, New Zealand to the port of Southampton, UK. Each reefer contains 10 boxes of lamb chops, weighing 10kg each and a through transport bill of lading terms. This through bill incorporates the Hague Visby Rules. To transport the reefers from Mary’s farm in Hamilton to Auckland for loading onto the container vessel, Container Lines engage the services of Trusty Trucks Ltd. The containers are picked up by Trusty Trucks the next day, the driver remembers to provide power to R1 but not R2. The containers reach the port on schedule and are loaded on to the MV Blue Skies, which Maersk are the time charterers. During her voyage the vessel encounters bad weather and rolls heavily, losing R1 overboard. Upon arrival at Southampton, the remaining unit R2 is discharged and delivered to the consignee. As the goods are devanned, it is apparent that they are rancid

Please answer the following questions:

Q1. The consignee invites Container Lines to a survey of container R2, should you give the surveyor any specific instructions?

Following the survey, Container Lines do not hear any further from Mary’s or the consignee. Nine months after discharge, Container Lines is contacted by a recovery agent purporting to be representing the subrogated insurer for both reefers and requesting settlement of USD200,000.

Q2. Set out your road map to how you would investigate this claim- how would you start to investigate this matter? What documents/information would you want to look at internally and what would you want to check with the recovery agent?

Q3. Assume the Hague Visby Rules apply to this shipment, are there any defences or limitation that could be used and what would you want to investigate? Any pitfalls?

 

Below, you will find the outputs from the public versions of five leading AI platforms – ChatGPT, Claude, Copilot, Gemini and Grok, but these have been shuffled and anonymised to prevent any biases.

This month we have invited Amanda Hastings, Head of Claims – Asia for Maersk, to join us as our expert guest judge. Along with Intent Communications CEO Namrata Nadkarni, they will be assessing the outputs. The results will be shared in a future edition of our monthly newsletter, so do sign up to learn who the winner is! We will include the link to the results at the bottom of this page once they are out!

Take a look at the outputs below and see whether any stand out to you. We’ll be carrying out our assessment before sharing our results at the end of the month.

OUTPUTS

———————————-

LLM 1: **Q1. Instructions for the surveyor of container R2** 

Yes, provide the surveyor with clear, specific instructions focused on establishing the cause, extent, and timing of the damage, particularly since this is a **reefer container** claim involving potential temperature abuse. The goal is to create a robust, contemporaneous record for defending or limiting liability. 

Key instructions should include: 

– **Inspect and document the container’s condition and equipment**: Check the reefer unit’s mechanical status (compressor, evaporator, etc.), any alarms or fault codes, power supply history (including when/where it was connected or disconnected), and whether the unit was properly plugged in during road transport, at the port, and on the vessel. Note any visible damage, tampering, or modifications to the container. 

– **Review temperature records**: Download and preserve all available data logger records, reefer unit logs (supply/return air temperatures, set point vs. actual), and any vessel or terminal monitoring data for the entire journey. Compare against the shipper’s carriage instructions

(required temperature, ventilation settings, etc.). Identify any excursions, duration, and when they occurred (e.g., pre-loading road leg vs. sea voyage). 

– **Examine the cargo**: Detail the apparent condition upon opening (rancid smell, discoloration, texture, spoilage extent—partial or total). Take representative samples for lab analysis if needed (e.g., to confirm bacterial growth consistent with temperature abuse rather than inherent vice). Photograph everything extensively, including seals, stuffing pattern, and any condensation or ice buildup. 

– **Timeline and chain of custody**: Establish when power was (or was not) supplied, especially on the road leg by Trusty Trucks (noting the driver’s failure on R2). Cross-reference with loading/discharge times, vessel logs for weather or power issues, and any pre-trip inspection (PTI) records or stuffing reports from the shipper/farm. 

– **Joint survey protocol**: Invite all relevant parties (or their representatives) if possible, but protect Container Lines’ position by noting any non-attendance. Request the surveyor to opine on the probable cause(s) of spoilage and whether it aligns with a failure to maintain the cold chain. 

– **Additional practical steps**: Instruct the surveyor to act promptly to prevent further deterioration, quantify the loss (e.g., percentage affected), and preserve evidence (e.g., retain data loggers). Emphasize independence and factual reporting without speculation on legal liability. 

These steps help distinguish between pre-carriage issues (road leg, where Hague-Visby may not apply), sea carriage responsibilities, and any shipper/contributor faults (e.g., improper stuffing or initial temperature). 

**Q2. Roadmap to investigate the claim** 

Start promptly upon receiving the recovery agent’s approach, even though nine months have passed since discharge. The investigation must be systematic to assess liability, quantum, time bar issues, and recovery prospects against subcontractors (e.g., Trusty Trucks) or others. 

**How to start:** 

– Acknowledge the claim in writing (without admitting liability) and request full particulars immediately: copies of the through bill of lading, commercial invoice, packing list, survey reports (including the earlier one on R2), temperature logs, insurance policy/subrogation documents, and proof of loss quantum (USD200,000 breakdown for both R1 and R2). Ask the agent to confirm their authority and provide evidence of subrogation (assignment or rights from Mary’s/consignee/insurer). 

– Internally, assemble the claims team (including P&I correspondent if applicable) and notify any relevant insurers or Maersk (as time charterers) for coordination.

**Internal documents/information to review:** 

– **Core carriage documents**: The through bill of lading (check terms, incorporation of Hague-Visby, any exceptions for pre-carriage or refrigerated goods, package/unit descriptions for limitation, and identity of carrier). Booking confirmation, shipper instructions (temperature set point, carriage requirements), and any special stowage requests. 

– **Operational records**: For R1 (lost overboard)—vessel logs, weather reports, stability calculations, lashing/securing records, and any heavy weather notations. For R2—full temperature history across all legs (road by Trusty Trucks, port handling, sea voyage), power connection logs, PTI reports for the reefer units, loading/discharge reports, and container tracking data. 

– **Subcontractor records**: Agreement with Trusty Trucks (terms, insurance, indemnity provisions), driver logs/statements (especially the admission of forgetting power on R2), and any pre-carriage survey or handover documents. 

– **Internal communications**: Notes from the initial survey invitation, any prior correspondence with Mary’s/consignee (silence for nine months is relevant), and vessel/charterparty details with Maersk (to clarify responsibility as time charterers—typically the carrier under the bill issues liability, but charter terms may allow recourse). 

– **Financial/quantum**: Any declared value on the bill, cargo description/weight, and market value evidence to test the USD200,000 claim. 

**What to check with the recovery agent:** 

– Full substantiation of the claim: Detailed breakdown (separate for R1 total loss and R2 spoilage), supporting invoices, mitigation efforts (e.g., salvage/sale of any sound portion of R2), and independent survey/ lab reports. 

– Timeline: Exact dates of discharge, when damage was first noted, and any notices given within required periods (e.g., apparent damage notice under Hague-Visby Art. III r.6). – Subrogation proof and standing: Who the insurer is, policy details, and confirmation they step into the shoes of the original claimant. 

– Any other potential claims or parallel actions. 

Simultaneously, preserve all evidence (data logs can be overwritten) and consider protective measures like time extensions if needed. If the claim appears weak (e.g., time bar or clear pre-carriage fault), this early scrutiny can support a robust rejection or low settlement. Also investigate recovery from Trusty Trucks for the R2 power failure and any vessel-related issues for R1. 

**Q3. Defences, limitations under Hague-Visby Rules (assuming they apply), investigations, and pitfalls** 

Assuming the through bill incorporates the **Hague-Visby Rules** (HVR) and they have the force of law or apply contractually (noting the NZ-UK route and through transport from inland Hamilton), the carrier’s period of responsibility is generally tackle-to-tackle (loading to discharge), though the through bill may extend it contractually. Pre-carriage (Hamilton to

Auckland by truck) is likely outside mandatory HVR application unless the bill expressly brings it in. 

**Potential defences (Art. IV r.2):** 

– **Perils of the sea (r.2(c))**: For R1 lost overboard due to bad weather and heavy rolling—this is a classic exception if the vessel was seaworthy and properly manned/equipped, and the loss was not due to carrier negligence. Heavy weather must be extraordinary, not merely rough conditions. 

– **Act, neglect, or default in the management of the ship (r.2(a))**: Potentially relevant to vessel handling in weather, but narrow—distinguished from cargo care. 

– **Inherent vice or nature of the goods (r.2(m))**: For R2 rancidity—if spoilage resulted from the lamb chops’ own properties rather than temperature failure (unlikely here, but testable via lab analysis). 

– **Insufficient packing or shipper fault (r.2(n) or (i))**: If the shipper failed to provide proper carriage instructions, stuff the container correctly, or pre-cool the cargo. 

– **For R2 specifically**: Any failure to care for the cargo (Art. III r.2) must be proven by the claimant; the carrier can argue the power omission occurred pre-sea carriage or that due diligence was exercised where responsibility lay. The truck leg fault likely falls on Trusty Trucks, subject to the through bill’s subcontract terms. 

The carrier must prove the exception applies and that it exercised due diligence to make the ship/container fit for carriage (Art. III r.1), including reefers (seaworthiness extends to refrigerating equipment). 

**Limitation of liability (Art. IV r.5):** 

– 666.67 SDR per package or unit, or 2 SDR per kg gross weight of the goods lost/damaged, whichever is higher. 

– For containerised cargo: If the bill enumerates the number of packages/units “as packed” in the container (here, “10 boxes of lamb chops” per reefer), each box may count separately for limitation, not the container as one unit. This can significantly increase the limit (e.g., 20 boxes total across R1/R2). Quantum would be calculated per the damaged/lost goods. – Limitation breaks only if the claimant proves the damage resulted from the carrier’s (or servant’s) act/omission done with intent to cause damage or recklessly with knowledge that damage would probably result (Art. IV r.5(e))—a high threshold (e.g., not mere negligence like forgetting to plug in power). 

**Key investigations needed:** 

– Exact application of HVR: Confirm via bill terms, ports involved (NZ/UK status), and whether they govern the whole through transport or only sea leg. Check for any paramount clause variations. 

– Causation split: R1 (sea peril vs. inadequate lashing/stowage); R2 (pre-carriage truck fault vs. sea leg failure; temperature logs crucial). 

– Seaworthiness/due diligence: Vessel and reefer container condition, maintenance records, crew actions in weather.

– Package enumeration on the bill for accurate limitation calculation. 

– Quantum and mitigation: Independent valuation, proof of loss. 

**Pitfalls:** 

– **Time bar (Art. III r.6)**: The carrier and ship are discharged from “all liability whatsoever” unless suit is brought within one year of delivery (or when goods should have been delivered). This applies broadly, including to misdelivery or post-discharge issues in many jurisdictions. Nine months have passed with no suit or formal claim from Mary’s/consignee—only a recovery agent now contacting. If no proceedings started and no extension agreed, the claim may be time-barred. The silence after the survey is notable; check if any notice preserved rights. Shorter contractual bars (e.g., 9 months) may be overridden by mandatory HVR one-year where applicable. 

– **Through bill complexities**: Liability may be segmented (pre-carriage often at lower limits or different regime, e.g., under NZ Carriage of Goods Act for road). Subcontractor recourse (Trusty Trucks) must be preserved before their own time bars expire. 

– **Maersk as time charterers**: The bill issuer (Container Lines) is typically the contracting carrier; charterparty terms may allow indemnity/recourse against Maersk for vessel issues (e.g., R1 loss), but do not automatically transfer HVR defences. 

– **Evidential gaps**: Missing temperature logs or delayed survey can weaken defences. Contributory negligence by shipper (e.g., no instructions) or failure to mitigate. – **Jurisdiction/forum**: Through bill likely specifies law/jurisdiction; NZ/UK differences in HVR application or inland carriage rules could arise. 

– **Breaking limitation**: Rare, but reckless disregard (e.g., knowingly sailing with unpowered reefer) must be watched. 

Overall strategy: Strongly investigate the time bar first—it could dispose of the claim entirely. If live, focus on splitting liability (truck fault for R2, peril of sea for R1) and applying package limitation. Engage experts (surveyors, meteorologists if needed) early and consider protective recovery actions against subcontractors. Consult local counsel on HVR applicability and time bar given the international elements. 

Here is a summarised list of the main sources used to provide the previous answer on the Mary’s Little Lamb Co. Ltd cargo claim scenario (focusing on Hague-Visby Rules application, defences, limitation, time bar, through bills, reefer surveys, and investigation steps): 

Primary Legal Texts 

• Hague-Visby Rules (1924 as amended by 1968 Visby Protocol and 1979 SDR Protocol) — Full text of key provisions, especially: 

○ Article III Rule 6 (one-year time bar from delivery or when goods should have been delivered)

○ Article IV Rule 2 (excepted perils, including (c) perils of the sea / heavy weather, (m) inherent vice) 

○ Article IV Rule 1 (due diligence on seaworthiness) 

○ Article IV Rule 5 (package/weight limitation: 666.67 SDR per package/unit or 2 SDR per kg, whichever higher) (Direct reference via standard consolidated texts, e.g., dutchcivillaw.com edition). 

Key Industry & P&I Club Guidance 

• Swedish Club — Cargo liabilities section explaining Article IV Rule 2(c) perils of the sea, heavy weather examples, carrier obligations for container/reefer due diligence, and proof burdens. 
• Steamship Mutual — Articles on heavy weather as a peril of the sea defence, scope of Article III Rule 6 time bar (including post-discharge application), and through transport issues. 

Case Law & Judicial Commentary 

• Perils of the sea / heavy weather: References to The Bunga Seroja (Australian approach to exceptional weather), The Tilia Gorthon, and general common-law principles (foreseeability vs. exceptional conditions). 
• Time bar (Article III Rule 6): UK Supreme Court confirmation in KCH Shipping v. V2 (2024) that the one-year bar applies broadly, including to misdelivery and post-discharge claims. 
• Limitation (Article IV Rule 5): The Thorco Lineage (2023) on calculation of “goods lost or damaged” (including economic loss) and package/weight limits. 

Through / Multimodal Bills & Network Liability 

• General commentaries on through transport bills of lading, network clauses (liability limited to the sea leg under Hague-Visby), and application of Rules only to tackle-to-tackle or as contractually extended (e.g., Conlinebill examples, FIATA combined transport). 
• Discussions on subcontractor (road leg) responsibility and how through bills interact with local law (e.g., New Zealand road carriage). 

Practical / Claims Handling Sources 

• Reefer container claim guidance: Temperature abuse, power supply records, survey best practices for spoilage (rancidity in meat), pre-loading vs. voyage damage localisation, and joint survey instructions (from cold-chain and marine cargo claims resources). 
• P&I and loss prevention materials on reefer care, inherent vice in perishable goods (lamb chops), and investigation roadmaps for subrogated insurer claims.

The answer synthesised these into a practical, scenario-specific response rather than relying on any single source. No specific New Zealand statute excerpts or Maersk bill wording were quoted verbatim; analysis drew from standard maritime law principles applicable to through bills incorporating Hague-Visby Rules.

LLM 2: 

Container Lines should instruct the surveyor to carefully document the condition of R2, including temperature records, reefer power supply history, and packaging integrity, as this evidence will be critical for liability assessment. The claim investigation must begin 

with gathering internal documents (bill of lading, reefer logs, trucking records) and verifying the insurer’s authority, while Hague-Visby Rules provide potential defenses such as “inherent vice” and limitation of liability to 666.67 SDR per package or 2 SDR/kg. 

Q1: Survey Instructions 

• Specific instructions to surveyor: 

○ Record reefer container number, seal integrity, and condition of goods at unpacking. 

○ Check reefer temperature logs and whether power was supplied continuously. ○ Note packaging condition (cartons, insulation, signs of thawing/refreezing). ○ Identify cause of damage (e.g., lack of power vs. inherent defect in meat). ○ Take photographs and samples for independent testing. 

• Purpose: Ensure evidence is preserved to defend against later claims. hansatic.com

Q2: Roadmap for Investigating the Claim 

Internal documents to review: 

• Through bill of lading (terms, incorporation of Hague-Visby Rules). 
• Commercial invoice & packing list (value of lamb chops). 
• Trucking records from Trusty Trucks Ltd (reefer plug-in logs, driver’s notes). ● Vessel stowage plan & logbooks (location of R1, weather reports). 
• Reefer monitoring records (temperature readings during voyage).
• Correspondence with consignee (delivery notes, survey reports). charterama.com Checks with recovery agent: 
• Confirm authority to act (letter of subrogation, insurance policy details). ● Request survey reports, claim calculations, and invoices supporting USD200,000 claim. 
• Verify timeliness: Hague-Visby Rules impose a one-year time bar from delivery/loss. salalahcargo.com

Q3: Hague-Visby Defences & Limitations 

Possible defences: 

• Article IV(2)(a): Act/neglect in navigation or ship management – loss of R1 overboard due to heavy weather may be exempt. 
• Article IV(2)(m): Inherent vice/quality of goods – rancidity in R2 could be argued as inherent defect in lamb, though reefer mismanagement weakens this. Springer

Limitation of liability: 

• Article IV Rule 5(a): 666.67 SDR per package or 2 SDR/kg. 

○ Each box = one package → 10 boxes × 10kg each per reefer. 

○ For R1 (lost): 100kg total → limit = higher of 666.67 SDR × 10 packages or 2 SDR/kg × 100kg. 

○ For R2 (damaged): same calculation applies. Steamship Mutual 

Pitfalls: 

• Time bar: Claim presented nine months after discharge is within one year, but must check exact delivery date. 
• Package definition disputes: Courts differ on whether the container or each box counts as a “package.” 
• Due diligence obligation: Carrier must prove vessel was seaworthy and reefer properly maintained. Failure to supply power to R2 undermines defense. shiplawmatters.com

LLM 3: 

Here’s a structured, practical response to each question from a carrier/claims-handling perspective. 

Q1. Survey of container R2 — instructions to surveyor 

Yes — you should give clear and targeted instructions, because the survey report will likely become key evidence. 

Focus the surveyor on causation and condition evidence, not just damage description: Key instructions 

1. Temperature history 

○ Retrieve and analyse reefer data logger / download records 

○ Check: 

■ Set temperature vs actual temperature 

■ Duration of any deviation 

■ Whether the unit was ever powered pre-loading 

2. Power supply / handling 

○ Confirm whether the reefer unit was: 

■ Plugged in during inland haulage 

■ Plugged in at terminal pre-loading 

○ Look for evidence of prolonged non-operation 

3. Condition of cargo

○ Nature of damage: rancidity suggests temperature abuse over time, not sudden failure 

○ Establish when deterioration likely began 

4. Packaging & stuffing 

○ Was cargo: 

■ Properly packed? 

■ Pre-cooled before stuffing? 

○ Any inherent vice or defect? 

5. Reefer machinery condition 

○ Any malfunction or was it fully operational? 

○ Check maintenance records if available 

6. Timeline reconstruction 

○ From pickup → port → voyage → discharge 

○ Identify critical window of damage 

7. Photographic & documentary evidence 

○ Internal condition of container 

○ Thermograph printouts 

○ Cargo state upon devanning 

�� Goal: Build evidence that damage occurred before the sea leg (i.e. during trucking when R2 was not powered). 

Q2. Roadmap to investigate the USD 200,000 claim 

Treat this as a two-part loss: 

• R1: total loss overboard 
• R2: cargo damage (rancid) 

Step 1: Immediate claim validation 

Request from recovery agent: 

• Proof of: 

○ Title to sue (bill of lading holder) 

○ Subrogation rights (insurance payment evidence) 

• Full claim breakdown
• Supporting documents: 

○ Commercial invoice 

○ Packing list 

○ Survey report 

○ Photos 

○ Temperature records (if they have any) 

Step 2: Internal document review Contractual documents 

• Bill of lading (through B/L) 

○ Terms 

○ Himalaya clause 

○ Subcontracting clauses 

• Applicable law/jurisdiction clause 

Operational records 

• Booking confirmation 
• Reefer instructions (temperature settings) ● Stuffing details 
• Pre-trip inspection (PTI) records 

Transport chain documents 

• Trucking instructions to Trusty Trucks 
• Interchange receipts (EIRs) 
• Terminal handling records 
• Plug-in logs at terminal 

Vessel-side documents (for R1) 

• Deck stowage plan (was it on deck?) 
• Weather reports 
• Logbook entries 
• Incident report (loss overboard) 
• Lashing/securing records

Step 3: Identify liability segments 

R2 (rancid cargo) 

Likely issue: 

• Failure to power reefer during inland transport 

→ Investigate: 

• Was Trusty Trucks instructed to provide power? 
• Was this obligation documented? 
• Did Container Lines exercise due diligence in selecting subcontractor? R1 (lost overboard) 

→ Investigate: 

• Was loss due to: 

○ Perils of the sea? 

○ Improper stowage/lashing? 

• Was container carried on deck? 

○ If yes → check clause permitting deck carriage 

Step 4: Liability apportionment 

• Consider: 

○ Subcontractor liability (Trusty Trucks) 

○ Potential recourse claim 

• Check indemnities in subcontract 

Step 5: Time bar analysis 

• Hague-Visby: 1 year time bar 
• Claim presented at 9 months 

→ Not time-barred yet, but monitor closely

Step 6: Quantum assessment 

• Verify: 

○ Cargo value 

○ Weight 

○ Number of packages 

• Apply limitation (see Q3) 

Q3. Hague-Visby Rules — defences & limitation 

1. For R2 (rancid cargo) 

Primary defence strategy 

Try to show: 

�� Damage occurred before loading on vessel 

Under Hague-Visby: 

• Carrier responsible “tackle to tackle” 
• Inland leg may fall outside mandatory scope, depending on wording Key arguments 
• Damage caused by: 

○ Failure to power reefer during trucking 

○ Therefore pre-loading damage 

• If through B/L extends Hague-Visby: 

○ Still argue excepted cause or lack of negligence 

Relevant defences (Art IV Rule 2) 

• (m) Inherent vice (if applicable, though weak here) 
• (q) Any other cause without actual fault/privity 

�� Strongest position: 

Damage occurred before carrier’s period of responsibility

1. For R1 (lost overboard) Defences 
2. Perils of the sea (Art IV r2(c)) 

○ Heavy weather 

○ Must show: 

■ Not foreseeable/avoidable 

■ Vessel seaworthy 

2. Error in navigation (Art IV r2(a)) ○ If applicable (less likely here) 

Critical issue: seaworthiness 

Carrier must prove: 

• Proper stowage 
• Adequate lashing 
• Vessel fit for voyage 

If not → defence fails 

1. Limitation of liability Under Hague-Visby: 

• 666.67 SDR per package, or 
• 2 SDR per kg, whichever higher 

Apply to: 

• Each container? OR contents? 

�� Depends on: 

• Whether packages are enumerated in B/L If B/L states:
• “10 boxes” → each box = package 
• Otherwise → container = package (much lower limit) 

1. Potential pitfalls 
2. Through bill of lading 

○ May extend liability inland 

○ Could undermine “pre-loading” defence 

2. Failure to exercise due diligence 

○ In selecting Trusty Trucks 

○ Could expose Container Lines 

3. Reefer obligations 

○ Carrier often responsible for: 

■ Proper care of temperature-controlled cargo 

○ Courts scrutinise reefer cases closely 

4. Delay in responding 

○ 9 months silence → not fatal, but weakens position 5. Deck carriage 

○ If undeclared → loss of defences

LLM4 

This is a classic multimodal transport scenario involving the Hague-Visby Rules (HVR), a “through” bill of lading, and the complexities of temperature-controlled cargo. 

Below is the strategic breakdown for investigating and defending these claims. 

Q1: Instructions to the Surveyor (Container R2) 

When dealing with a reefer claim, the surveyor is your “eyes and ears” on the ground. You aren’t just checking if the lamb is bad; you are looking for why it went bad. 

Specific instructions should include: 

• Partitive Sampling: Conduct sensory (smell/touch) and laboratory tests (microbiological/pH) to determine the exact nature of the decay. 
• Data Logger Download: Extract the “Partlow” chart or digital data logger from the reefer unit to identify exactly when the temperature deviated. 
• Physical Inspection of the Unit: Check the reefer’s seals, vents (should be closed for frozen meat), and the machinery for any mechanical failures. 
• Pulp Temperatures: Take core temperatures of the lamb chops immediately upon opening the doors. 
• Pre-cooling & Loading Records: Verify if the meat was loaded at the correct “carrying temperature” or if it was “warm-loaded” by the shipper. 

Q2: Investigation Roadmap 

Since you are nine months post-discharge, you are nearing the one-year time bar under HVR Art III r 6. Speed is essential. 

Internal Investigation (The “Paper Trail”) 

• The Contract of Carriage: Review the Through Bill of Lading. Does it have a “Clause Paramount”? Does it allow for subcontracting (Liberty Clause/Himalaya Clause)?
• The Logbooks: Check the vessel’s deck logs for the “bad weather” mentioned during the loss of R1. 
• The Trucking Records: Review the “Interchange Receipts” or “Waybills” from Trusty Trucks Ltd. 
• Pre-Trip Inspection (PTI): Check the certificate ensuring the reefer unit was functioning correctly before being handed to Mary’s. 

Verification with the Recovery Agent 

• Title to Sue: Ask for the endorsed Bill of Lading and the Letter of Subrogation. Does this agent actually have the legal right to claim? 
• Quantum (Damages): Request the commercial invoices and packing lists. USD 200,000 for 200kg of lamb (20 boxes total) seems mathematically astronomical—that’s USD 1,000/kg. This is a major red flag. 
• Mitigation of Loss: Ask for proof of disposal or salvage sale. Did the consignee try to sell the lamb for pet food or rendering to reduce the loss? 

Q3: Defences, Limitations, and Pitfalls 

Under the Hague-Visby Rules, your defense strategy splits between the two containers. 

1. Defences (Art IV r 2) 

• For R1 (Lost Overboard): Use Art IV r 2(c) “Perils, dangers and accidents of the sea.” You must prove the weather was “extraordinary” and that the container was properly lashed. 
• For R2 (Rancid Lamb): The defense is likely Art IV r 2(q) “Any other cause arising without the actual fault or privity of the carrier.” If the damage happened while with Trusty Trucks (inland), the “through bill” terms might shift liability depending on whether it’s a “network” or “uniform” liability clause. 

2. Limitation of Liability (Art IV r 5) 

This is your strongest shield if the USD 200,000 claim is valid. Under HVR, liability is limited to the higher of: 

1. 2 SDR per kilogram of gross weight. 
2. 666.67 SDR per package/unit. 

Calculation Table (Estimated):

Unit

Quantity

Calculation (Package)

Calculation (Weight)

R1	10 Boxes	10 x 666.67 SDR	100kg x 2 SDR
R2	10 Boxes	10 x 666.67 SDR	100kg x 2 SDR

Note: Since 666.67 SDR (approx. USD 880) per box is higher than the weight limit, your liability would likely be capped around 13,333.40 SDR total (approx. USD 17,700)—far below the USD 200,000 requested. 

3. Pitfalls to Watch For 

• The “Himalaya Clause”: Ensure your contract protects your subcontractors (Trusty Trucks). If not, the claimant might sue the trucker directly to bypass HVR limits. ● Deviation: If the vessel “deviated” from its route without reason, you might lose the right to limit liability. 
• Apportionment of Fault: If R2 was damaged because the driver forgot power (Trusty Trucks’ fault), but Container Lines failed to check the unit at the port, you may have shared liability. 

Sources Used 

• Hague-Visby Rules (1968): Specifically Article III (Carrier duties), Article IV (Exceptions and Limitations), and Article III r 6 (Time bar). 
• Carriage of Goods by Sea Act (COGSA): Relevant for the legal framework of bills of lading. 
• Standard P&I Club Reefer Guidelines: Regarding surveyor instructions and pulp temperature protocols.

Mary’s Little Lamb Co. Ltd v Container Lines Ltd

Legal & Claims Analysis 

Q1: Survey Instructions for Container R2 

When attending the joint survey of R2, the surveyor should be instructed as follows: Documentation & Preservation 

• Photograph and video everything before the container is opened — the seals, seal numbers, exterior condition, ventilation ports, and the reefer unit’s control panel display. ● Record and photograph the reefer’s temperature data logger / download the electronic temperature recorder (ETR) printout immediately. This is the single most critical piece of evidence. It will show the entire temperature history from plug-in to discharge. Do not allow the cargo interests’ surveyor to be the sole party downloading this data. 
• Note and photograph the set point temperature vs the actual recorded temperature throughout the voyage. 
• Record the power supply connection log — when was R2 plugged in at the farm, at the port, and on the vessel? Were there any gaps? 

Container & Cargo Condition 

• Record the condition of each of the 10 boxes — are all 10 boxes rancid, or only some? Is the deterioration uniform throughout the container, suggesting a consistent temperature failure, or patchy? 
• Note the packaging condition — is there any evidence of pre-existing damage, improper packing, or inadequate packaging by the shipper? 
• Check for any evidence of pre-shipment condition issues — discolouration, freezer burn, or signs the goods were not in prime condition before loading. 
• Record the smell, colour, and texture of the product in as much detail as possible. ● Retain samples — insist that samples be retained in a frozen/controlled environment by a neutral party (e.g., a laboratory) for potential future testing. Ensure chain of custody is documented. 

Seal & Security Integrity 

• Record whether the original seals were intact on discharge. If seals were broken or replaced, this must be flagged — it raises questions about whether the container was interfered with. 
• Cross-reference seal numbers against the bill of lading and any port/vessel documentation. 

Reefer Machinery

• Check the reefer unit itself for any mechanical defects, alarms triggered, or fault codes stored in its memory. 
• Note the brand and model of the reefer unit — this may be relevant if there is a manufacturer defect argument. 

General Instructions 

• The surveyor attends without prejudice and without admission of liability. ● Do not make any admissions or comments on liability during the survey. ● Ensure Container Lines’ surveyor is present throughout and does not allow cargo interests’ surveyor to conduct any tests unilaterally. 
• Obtain a copy of the joint survey report before signing — do not sign any report that contains conclusions on liability. 

Q2: Road Map for Investigating the Claim 

Nine months have passed since discharge. The recovery agent is acting for the subrogated insurer, meaning the cargo insurer has already paid out the consignee/shipper and has stepped into their shoes. A structured investigation is essential. 

1. Internal Documents to Gather Immediately 

Bill of Lading & Contract Documents 

• The through bill of lading for both R1 and R2 — check the precise terms, the incorporated rules (Hague-Visby), the identity of the carrier, the description of goods, weight, condition on receipt, and any clauses (e.g., shipper’s load and count, said to contain). 
• Any letters of indemnity or special instructions relating to the reefer settings or temperature requirements. 
• The booking confirmation and any special cargo instructions from Mary’s regarding temperature set points. 

Operational Records — Pre-Carriage (Hamilton to Auckland) 

• The sub-contract with Trusty Trucks — what were the terms? Was Trusty Trucks acting as Container Lines’ agent or as an independent contractor? This is critical for determining Container Lines’ liability for the trucking leg under the through bill. 
• Trusty Trucks’ delivery receipt / interchange receipt — what was the condition of R2 when collected and when delivered to port? Was power noted as connected or disconnected? 
• Any pre-trip inspection (PTI) records for R2 — was the reefer unit inspected before loading onto the truck?
• GPS/telematics data from Trusty Trucks’ vehicle, if available, to establish timeline. ● Port arrival records — when did R2 arrive at Auckland port, and when was it plugged in at the terminal? 

Vessel Records (MV Blue Skies) 

• The reefer monitoring logs from the vessel for R2 — modern vessels monitor reefer containers continuously. These logs will show temperature, alarms, and any interventions. 
• The mate’s receipt and cargo manifest — condition on loading. 
• The vessel’s deck/engine log for the voyage — weather encountered, any incidents. ● The reefer plug connection records at the port terminal in Auckland — was R2 plugged in promptly after arrival at the terminal? 

Survey Report 

• The joint survey report from Southampton — review carefully. 
• The ETR/temperature logger data — this is the centrepiece of the investigation. Map the temperature history against the known events: farm pickup, truck journey, port terminal dwell, loading, voyage, discharge. 

Cargo Description & Condition on Shipment 

• Any phytosanitary or veterinary certificates issued at origin — these will state the condition of the goods when they left the farm. 
• Packing list and commercial invoice — confirm the goods description and value. ● Evidence of pre-shipment cold chain — was R2 pre-cooled before loading at the farm? 

1. What to Check with the Recovery Agent 

Authority & Standing 

• Request a copy of the subrogation receipt / letter of subrogation — confirm the insurer has properly paid the claim and is entitled to sue in the shoes of the assured. ● Request a copy of the cargo insurance policy — check the insured value, the basis of valuation, and whether the policy covers reefer breakdown or negligence of carriers. ● Confirm who the assured is — is it Mary’s (the shipper) or the consignee? This affects the chain of title to sue under the bill of lading. 

The Quantum — USD 200,000 

• This figure covers both R1 and R2. The recovery agent must provide a breakdown. The two containers involve entirely different causes of loss (overboard vs reefer failure) and will be analysed separately. 
• For R2: Request the survey report, laboratory analysis, and any third-party valuation supporting the claimed value of the rancid goods.
• For R1: Request evidence of the value of the cargo lost overboard — packing list, commercial invoice, any customs entry at origin. 
• Check whether the claimed value includes freight, insurance, and a mark-up (CIF + 10% is standard under cargo policies) — if so, confirm this is consistent with the policy terms and the Hague-Visby limitation calculation. 
• Ask whether any salvage or residual value has been deducted from the R2 claim (rancid goods may still have some value, e.g., as pet food). 

Time Bar 

• Under the Hague-Visby Rules (Article III Rule 6), the time bar for cargo claims is one year from delivery or the date when the goods should have been delivered. For R2, time runs from the date of delivery at Southampton. For R1 (lost overboard), time runs from the date when the goods should have been delivered. 
• Nine months have passed — the one-year time bar has not yet expired, but it is approaching. This must be diarised urgently. Container Lines should consider whether to issue protective proceedings or seek a time bar extension agreement. 
• Check if there is any notice of claim — Article III Rule 6 requires written notice of loss or damage to be given at or before delivery, or within three days of delivery if the loss is not apparent. Was any notice given? If not, there is a presumption of delivery in accordance with the bill of lading (though this is rebuttable). 

Q3: Hague-Visby Rules — Defences, Limitation & Pitfalls Applicable Defences 

Article IV Rule 2 — Catalogue of Defences 

The following are most relevant: 

(a) Act, neglect or default of the master, mariner, pilot or servants of the carrier in the navigation or management of the ship (Article IV Rule 2(a)) 

• The loss of R1 overboard during bad weather may engage this defence if the rolling was attributable to navigational decisions (e.g., course, speed in heavy weather). However, this defence is narrow — it applies to navigation or management of the ship, not management of the cargo. If the container was inadequately secured, this is cargo management, not ship management, and the defence will not apply. 
• Investigate the stowage and securing of R1 — were the twist locks and lashing correctly applied? Were container securing logs maintained? 

(b) Perils of the sea (Article IV Rule 2(c))

• If the weather encountered was genuinely exceptional and unforeseeable, this defence may apply to R1. Obtain the vessel’s weather logs, the official log book, and any third-party meteorological reports (e.g., from a marine weather service) to assess whether the weather constituted a “peril of the sea” or was foreseeable and manageable. 
• Note: bad weather alone is not sufficient — it must be of an extraordinary nature that could not be guarded against by the exercise of ordinary seamanship. 

(c) Inherent vice (Article IV Rule 2(m)) 

• For R2, if the goods were already deteriorating before shipment (e.g., if the cold chain at the farm was inadequate), inherent vice may be a partial or full defence. The ETR data and pre-shipment certificates are key. 

(d) Act or omission of the shipper (Article IV Rule 2(i)) 

• If Mary’s failed to pre-cool the container, provided incorrect temperature instructions, or loaded goods that were not in sound condition, this may constitute a fault of the shipper. 

(e) Latent defects not discoverable by due diligence (Article IV Rule 2(p)) 

• If R2’s reefer unit had a latent mechanical defect, this may be a defence — but Container Lines would need to show that due diligence could not have detected it at the pre-trip inspection stage. 

Seaworthiness — Article III Rule 1 

Container Lines (as carrier under the through bill) owes an absolute, non-delegable duty to exercise due diligence before and at the commencement of the voyage to make the ship seaworthy, including properly equipping and supplying the vessel and making the holds and reefer points fit for the cargo. If R2’s reefer points were defective or not monitored, this could defeat any defences. 

Note: the duty is only to exercise due diligence — it is not an absolute warranty of seaworthiness (unlike the common law position). The burden is on the carrier to prove due diligence was exercised. 

Limitation of Liability — Article IV Rule 5 

Under the Hague-Visby Rules, liability is limited to the higher of: 

• 666.67 SDR per package or unit, or 
• 2 SDR per kilogram of gross weight 

For R2 (the rancid goods claim):

• Each box of lamb chops is likely the relevant “package.” There are 10 boxes × 10kg = 100kg total. 
• Per package: 10 boxes × 666.67 SDR = 6,666.7 SDR (~USD 8,800 at current rates). ● Per kilogram: 100kg × 2 SDR = 200 SDR (~USD 264). 
• The per-package calculation is higher and would therefore apply — approximately USD 8,800 for R2. 

For R1 (lost overboard): 

• Same calculation — 10 boxes × 666.67 SDR = 6,666.7 SDR (~USD 8,800). 

The combined Hague-Visby limit is therefore approximately USD 17,600 — a fraction of the USD 200,000 claimed. This is a very significant point in Container Lines’ favour. 

Important caveat on package: If the bill of lading describes the goods as “2 reefer containers” rather than identifying the individual boxes, the “package” could be argued to be the container, not the box, which would dramatically reduce the per-unit limit if the container itself is the package. However, under the Hague-Visby Rules, if the individual packages are enumerated in the bill of lading, those enumerated packages are the relevant unit — check the bill of lading carefully. 

Breaking the limit — Article IV Rule 5(e) Limitation can be broken if the claimant proves the damage resulted from an act or omission of the carrier done with intent to cause damage, or recklessly and with knowledge that damage would probably result. This is a high bar. However, if the failure to power R2 (by Trusty Trucks, acting as Container Lines’ agent) is characterised as reckless, claimants may attempt to argue this. Investigate whether there was any system or checklist that should have ensured power was connected — if Container Lines had a procedure that was ignored, this could be embarrassing, though it would still fall short of the “reckless + knowledge” standard. 

The Pre-Carriage Leg — Trusty Trucks 

The through bill means Container Lines is contractually responsible to the shipper for the entire journey, including the Hamilton-to-Auckland road leg. Container Lines cannot avoid liability to the cargo interest by pointing to Trusty Trucks. However, Container Lines will have a back-to-back claim against Trusty Trucks for the failure to power R2. 

The key question is whether that sub-contract incorporates any limitation of liability (e.g., the New Zealand Contract and Commercial Law Act 2017, or standard road carrier terms). Hague-Visby Rules do not apply to the road leg — road carriage in New Zealand is governed by domestic law and contract. 

Key Pitfalls

1. Time bar — as noted, the one-year Hague-Visby limitation under Article III Rule 6 is the most urgent issue. If it expires without suit being filed, the claim is extinguished. Diary this immediately. 
2. Notice of claim — check whether proper notice was given under Article III Rule 6. If no written notice was given within three days of delivery for R2, the presumption of sound delivery applies (though this is rebuttable by the claimant). 
3. Separating R1 and R2 — the USD 200,000 global demand must be broken down. R1 (lost overboard) and R2 (reefer failure) have different causation, different defences, and different evidentiary requirements. Do not negotiate them as a single undifferentiated claim. 
4. Identity of carrier — under the through bill, Container Lines is the contractual carrier. But for the sea leg, if Maersk as time charterer issued their own bills or if there is a demise clause, the identity of the “carrier” for Hague-Visby purposes may be contested. Check the face of the bill of lading carefully. 
5. Subrogation chain — if the cargo insurer has not properly paid the full value and obtained a valid subrogation receipt from both Mary’s and the consignee, their standing to bring the claim may be defective.
