Australian mining company BHP Group Ltd. was on Monday denied permission to appeal a London court ruling that it is liable for the 2015 collapse of a dam in southeastern Brazil, in a lawsuit potentially worth up to 36 billion British pounds ($48.3 billion), Reuters reported.

The collapse of the Fundao dam released a wave of toxic sludge and remains the worst environmental disaster in Brazil’s history.
