In a judgment dated 3 July 2014, the Commercial Court determined three preliminary issues relating to the claimant’s ability to recover post-award interest on sums awarded in four Russian (ICAC) arbitral awards. The claimant claimed interest on two alternative bases: under art 395 of the Russian Civil Code and/or section 35A of the Senior Courts Act 1981 (SCA 1981). The court held that interest on the awards could not be recovered prior to the date on which the awards received a writ of execution (exequatur) from the Russian courts, but that interest on the sums claimed in the English enforcement proceedings could be recovered, in principle, under SCA 1981, s 35A. Further, the judge held that the court had power to enforce the claimant’s awards at common law notwithstanding decisions of the Russian courts that set the awards aside. In this article, we discuss the practical implications of the decision and highlight key points from the judgment.
