A British high court judge on Tuesday denied Gibson, Dunn & Crutcher partner Peter Gray’s request for permission to appeal last month’s finding that he deliberately misled the court in presenting inaccurately dated evidence that implicated Djibouti businessman Abdourahman Boreh in a 2009 grenade attack.

“For the reasons I gave in the judgment, I am satisfied—regrettably satisfied, because I appreciate the effect this has on Mr Gray’s career, but satisfied nonetheless that he did deliberately mislead the court; and I do not consider that there is any real prospect of satisfying the Court of Appeal to the contrary,” Justice Julian Flaux wrote in his decision.
