McCANN AND OTHERS v. THE UNITED KINGDOM JUDGMENT 4 AS TO THE FACTS 12. The facts set out below, established by the Commission in its report of 4 March 1994 (see paragraphs 132 and 142 below), are drawn mainly from the transcript of evidence given at the Gibraltar inquest (see paragraph 103 below). I. PARTICULAR CIRCUMSTANCES OF THE CASE 13.
