Last month, the respected Brazilian Supreme Court Justice Teori Zavascki died in a plane crash. He was overseeing the largest corruption investigation in the country’s history. Even if his recently selected successor, Edson Fachin, rises to the occasion, Zavascki’s death remains a tragic loss and a blow to Brazil’s fight against corruption. Especially since it comes on the heels of lawmakers torpedoing in late 2016 a widely popular effort to make it easier for prosecutors and judges to clean up government.
