Brazil court convicts Samarco, ex-managers in Mariana dam collapse

TRF-6 partially overturned a lower court ruling, convicting Samarco Mineração and three former managers for the 2015 Fundão dam collapse in Mariana, which killed 19 people. This is the first criminal conviction in the case, marking a legal milestone in Brazil's worst environmental disaster. The ruling may set precedent for ongoing civil and criminal proceedings against the company and its shareholders.
