These are referred to as the “discriminatory grounds”.

On the 22nd December 2000, the European Council agreed the Regulation to replace the Brussels Convention on Jurisdiction and Enforcement of Judgments 1968 (“the Brussels Convention”). The purpose of the Regulation was to bring the law contained in the Brussels Convention into the main body of EC Law. The Regulation was implemented in Ireland by Statutory Instrument 52 of 2002, European Communities (Civil and Commercial Judgments) Regulations 2002, which came into force on the 1st March 2002.

    Unlike the United States, which is leading the way in relation to e-discovery and where the disclosure of electronic data has become standard procedure, as of yet there is no standard protocol or practice direction issued in relation to e-discovery in Ireland. Despite this fact, Irish lawyers are beginning to appreciate the invaluable nature of electronic data which can be retrieved and used in commercial litigation.
