The Consumer Financial Protection Bureau switched sides and backed a federal lawsuit by banks and business groups seeking to eliminate a fee cap the bureau set last year.

A federal judge on Tuesday threw out a US Consumer Financial Protection Bureau rule capping credit card late fees at $8, after the agency agreed with opponents that the rule adopted during President Joe Biden’s administration was illegal.

The Consumer Financial Protection Bureau issued a rule last year limiting late fees to $8, but on Monday it joined a coalition of industry groups in asking a court to vacate the rule.
