Limitation of liability conventions: why transport compensation is capped by treaty

The bargain behind capped compensation

Carriage treaties were negotiated to solve a commercial problem: carriers move goods whose value they cannot verify, in quantities they cannot individually assess, for prices unrelated to that value. Unlimited exposure would either price transport by the cargo rather than by the service, or push the risk into rates that every shipper pays regardless of what it ships. Capping compensation by a physical measure makes the carrier's exposure calculable and insurable, and leaves the cargo owner free to insure the actual value. That is why the limit is not a discount on the claim. It is the price of a system in which liability attaches without the claimant having to prove how the loss happened.

Units of account and why treaties avoid currencies

Treaty limits are expressed in an international unit of account rather than in any national currency, converted into local money at the date fixed by the regime or by the forum. The point is durability: a figure fixed in one currency would drift in real value as exchange rates and prices moved, and would advantage or penalise claimants according to where they happened to sue. The consequence for a claims file is that the applicable ceiling cannot be looked up once and reused. It depends on which regime governs, which amended version of that regime the relevant state has adopted, the weight or package count in issue, and the conversion date. Treat any figure circulating internally as a working assumption to be verified when it matters.

One movement, several possible regimes

A door-to-door shipment can pass through the scope of more than one treaty, and the regime that applies to a loss usually depends on where the loss occurred. Where the stage of the journey is known, network liability principles in many multimodal contracts apply the regime that would have governed that stage in isolation. Where the loss cannot be localised, the contract's fallback provision decides, and those fallbacks vary enormously between operators. Maritime law adds a second, separate layer. Alongside the cargo regimes, shipowners may in many states limit their overall liability for claims arising from an incident by constituting a fund under a global limitation convention administered through the maritime organisation. Cargo claims can therefore meet a cap twice: once per consignment, once against the vessel.

Breaking the limit, and the planned alternative

Most regimes remove the benefit of limitation where the damage resulted from the carrier's intent to cause it, or from recklessness with knowledge that damage would probably follow. The threshold is high, the conduct must usually be that of the carrier or its servants acting within their employment, and the standard of proof defeats most attempts. Building a commercial strategy on breaking limitation is unwise. The designed alternative is to raise the ceiling before the goods move. Carriage regimes generally permit a declaration of value or of a special interest in delivery, made on the transport document and usually attracting a supplement, after which the declared figure replaces the ordinary cap. For genuinely high-value consignments this is the mechanism the treaties expect shippers to use, alongside insurance on the goods.

Scope of this account

This is a description of how limitation works as a mechanism, offered for education rather than as legal advice. Which convention governs a given movement, in which amended form, and how a court would apply it to particular conduct are questions that turn on the contract, the states involved and the forum. Verify before relying.

Frequently asked questions

Why are treaty limits not written in euros or dollars?

Because a figure fixed in one currency would lose comparability as rates and prices moved, and would make outcomes depend on where a claimant sued. An international unit of account converted at a date fixed by the regime keeps the ceiling stable across states.

Can I contract for a higher limit with my carrier?

Usually yes. Carriage regimes typically forbid terms that lower the cargo interest's protection but permit terms that raise it, and most also allow a declaration of value or of a special interest in delivery, made before carriage and normally priced separately.

Which convention applies if the loss could have happened on any leg?

Where the stage cannot be identified, the contract decides, which is why the unlocalised-loss provision in a multimodal transport document is worth reading before signing it. Localised losses are more commonly governed by the regime applicable to that leg.
