Disputes over $68 million in attorney fees in a $240 million class action settlement against Wells Fargo & Co. have spurred a federal judge to consider setting new precedents for contract lawyer fees.

In a fairness hearing Thursday, U.S. District Judge Jon Tigar of the Northern District of California took issue with a motion for attorney fees filed by San Francisco’s Lieff Cabraser Heimann & Bernstein. The case involves a settlement with Wells Fargo shareholders over the financial institution’s widespread opening of unauthorized accounts to reach sales quotas and artificially inflate the company’s stock.
