In May 2020 the UK-based law firm Leigh Day notified Petra and Williamson Diamonds Limited ("WDL", owned 75% by Petra and 25% by the Government of Tanzania), that it had issued claim forms in the High Court of England and Wales on behalf of 32 anonymous individuals in relation to alleged breaches of human rights at the Williamson Mine ("the Mine") over a number of years.
