Global litigation firm Quinn Emanuel Urquhart & Sullivan stands accused of using $8 million in funds misappropriated from bondholders in a bankrupt oil company to sue them on behalf of its ousted director, according to a discovery request pending in Florida federal court.

The May 17 discovery request filed by bankrupt Singaporean drilling company Oro Negro Drilling and its affiliated companies comes in conjunction with ongoing criminal and bankruptcy proceedings in Mexico concerning alleged misappropriation of funds from company accounts by former directors.
