📦 Cargo Claims & Contract Interpretation

Hague-Visby Rules Interpretation

Case & Citation Principle
The Giannis NK
[1998] AC 605 (HL)
Infected cargo: “goods” under Article III does not include matter causing damage to cargo but not part of it.
The Kapitan Petko Voivoda
[2003] 2 Lloyd’s Rep 92
Package limitation applies per shipping unit, not per item within packages for containerized cargo.
The MSC Amsterdam
[2007] EWCA Civ 794

Practice Impact: These cases are cited in 90%+ of cargo damage disputes. Essential for bill of lading drafting and cargo insurance claims.

Charter Party Landmarks

Case & Citation Principle
The Eternal Bliss
[2021] EWCA Civ 1712
Demurrage is exclusive remedy for laytime breaches unless separate charter party breach proven.
RTI v MUR Shipping
[2024] UKSC 18
“Reasonable endeavours” in force majeure clauses requires surrender of valuable contractual rights in sanctions context.
The New Hydra
[2021] EWHC 566 (Comm)

“The Eternal Bliss represents a watershed moment in time charter jurisprudence, clarifying the relationship between demurrage and damages that had confused practitioners for decades.”
