What is arbitration-related litigation?

London is a leading seat for international arbitrations, chosen by parties around the world.

That reputation is based on the effectiveness of the Arbitration Act 1996, the quality and independence of the English judiciary, the breadth and depth of market-leading expertise of arbitration practitioners in the UK and the UK’s ratification of the New York Convention.

Where London is the seat of an arbitration, the English courts have supervisory jurisdiction over that arbitration, operating under the framework established by the Arbitration Act 1996. The English courts have a reputation for exercising that jurisdiction prudently and for adopting a “pro-arbitration” attitude. Their judgments are influential internationally.

The court’s involvement in this supervisory capacity can be triggered before arbitration is commenced, during the arbitration proceedings, and after the arbitration award has been issued (for example, in respect of challenges or appeals to the award or its enforcement).

Such proceedings can be fundamentally important to an arbitration, in certain cases determining whether the arbitration can proceed at all or whether an award has any effect.
