MOSCOW, May 26 (Reuters) - A Moscow arbitration court has upheld an application by the Russian central bank for the immediate enforcement of a ruling in its case against Euroclear, Euroclear's lawyers said on Tuesday.

On May 15 a court in Moscow upheld the Russian central bank's claim for damages from Euroclear related to the freezing of assets worth 18.17 trillion roubles ($252.38 billion).

Under Russian law, a court may order immediate enforcement of a judgment - at the claimant's request and where justified - if any delay could lead to significant losses or make enforcement impossible.
