Lula judge was biased, Brazil supreme court rules, paving way to challenge Bolsonaro

Former president's vindication could prove a precedent for other high-profile politicians and business leaders in prison

Brazil's supreme court has ruled that the former judge Sergio Moro was biased in the way he oversaw former President Luiz Inacio Lula da Silva's corruption trial, providing vindication for the leftist leader who has long claimed political persecution.

The decision further darkens the shadow over the reputation of Moro and the sweeping Car Wash" corruption investigation he presided over for years.
