Mintz Honored with PAIR’s 2020 Pro Bono Mentor Award
May 22, 2020
The first-of-its-kind class action lawsuit, Pereira Brito v. Barr, was filed in June on behalf of immigrants who were jailed due to flawed detention hearings in which the detainee was required to bear the burden of proof as to not being a flight risk or a danger to the community. The latest ruling holds that the class of immigrants are entitled to bond hearings at which the government bears the burden of justifying an immigrant’s detention, and at which the immigration court must consider someone’s ability to pay when setting a bond amount.
The Mintz pro bono team representing the plaintiffs in this case includes Members Susan Finegan and Susan Cohen, Special Counsel Andrew Nathanson, and Associates Mathilda McGee-Tubb, Jennifer Mather McCarthy, and Ryan Dougherty.
