Quinn Emanuel Urquhart & Sullivan faced heavy opposition in its bid to lead a multibillion-dollar class action accusing a dozen major investment banks of manipulating the market for credit default swaps. Not only were other plaintiffs lawyers vying to spearhead the case, but Simpson Thacher & Bartlett attempted to disqualify the firm over alleged conflicts.
