Reseau de Transport d’Électricité v Costain Ltd [2025] EWHC 73 (Admlty) -(30.01.25)

In November 2016, two undersea electricity cables connecting England and France were damaged after a collision between the Stema Barge II and the Saga Sky, causing the anchors of both vessels to drag over the cables. RTE sought damages from the Stema Interests, Network Rail, and Costain, while Stema UK attempted to limit liability under the 1976 Limitation Convention. After multiple proceedings, the Court of Appeal ruled that Stema UK could not limit its liability under the Convention, and the High Court barred Stema UK from raising a new limitation defense, citing principles of res judicata and cause of action estoppel because it was not an operator and did not thus come within the ambit of the relevant statute.
