Oral hearings regarding the proceedings took place in the Permanent Court of Arbitration, PCA, in The Hague in October 2002 before an international tribunal consisting of the chairman, Professor Michael Reisman, Mr. Gavan Griffith, QC, and Rt. Hon. Lord Michael Mustill, QC. Today, 2 July, the OSPAR tribunal published its judgment, making five principal determinations: a unanimous rejection of the United Kingdom's argument that the tribunal lacked jurisdiction; a unanimous rejection of the United Kingdom's argument that Ireland's claim was inadmissible; a two-to-one majority rejection of the United Kingdom's argument that Ireland had no right to sue at an international tribunal; a two-to-one majority rejection of Ireland's argument that the specific information requested was covered by the scope of OSPAR Convention; and a unanimous decision that each side should pay its own costs.
