Gibson Dunn & Crutcher partner Peter Gray “deliberately misled” the High Court when he submitted incorrectly dated evidence, a judge ruled today, as a hearing in a 2013 case between the Republic of Djibouti and one of its wealthiest citizens drew to a close.

Abdourahman Boreh had been convicted of terrorism for his involvement in a 2009 terrorist attack, in part because of the evidence Gray had submitted. But Mr Justice Flaux ruled that Gray knowingly submitted the incorrectly dated evidence.
