The Consumer Financial Protection Bureau dismissed another Biden-era lawsuit, this one targeting some of the world’s largest banks for allegedly rushing out a peer-to-peer payment network that then allowed fraud to proliferate.

The agency dropped the case against JPMorgan Chase & Co., Bank of America Corp. and Wells Fargo & Co. along with the parent company of the consumer payment network Zelle with prejudice, meaning it cannot be reopened, according to a filing Tuesday in U.S. District Court for the District of Arizona.

The lawsuit, filed at the end of last year, alleged that the banks’ lack of safeguards fostered “a gold mine for fraudsters, while often leaving victims to fend for themselves.” The banks said they disagreed with the action at the time.

The consumer protection agency has yanked a bevy of lawsuits filed against financial services companies during former President Joe Biden’s term. Cases against Capital One Financial Corp. and a unit of Rocket Cos. as well as one against fintech lender SoLo Funds were dropped last month.

The change in enforcement approach is taking place before President Donald Trump’s pick to lead the agency is confirmed. Jonathan McKernan, who formerly served as a Republican member of the Federal Deposit Insurance Corp. board, testified that he would follow the CFPB’s statutory obligations, which includes the enforcement of some consumer protection laws.

The consumer watchdog, established in the wake of the 2008 financial crisis, picked up its regulatory and enforcement speed under the Biden administration. It has been essentially shuttered since early February, when Trump administration officials began suspending its work overseeing financial companies and closing its Washington, DC, headquarters.
