A dozen barristers and judges, including Gibson, Dunn & Crutcher London partner Charlie Falconer, QC, penned an open letter on Sunday criticizing a Hong Kong court’s decision to send three student activists to prison for unlawful assembly.

In August, Joshua Wong, Alex Chow and Nathan Law were sentenced by the Court of Appeal to six-, seven- and eight-month prison terms respectively for their involvement in the Occupy Central pro-democracy protests in 2014.
