The Congressional Review Act enables Congress to void such rules, known as “midnight regulations” because they are issued during the closing days of an administration.

The law has only been used successfully once since its enactment when Department of Labor regulations governing ergonomics in the workplace were overturned.

However, House Republicans have expressed a desire to use the law at the end of the Obama Administration.

Donovan said CUNA and the Carolinas Credit Union League contacted the office of Rep. Mark Meadows (R-N.C.) to explain that rather than stifling business, the MBL rules would allow credit unions to expand lending.

Based on that argument, Meadows agreed to drop the rules from the documents.

“There…was no ill intent,” Donovan said.

Meadows's office did not respond to multiple messages.

Donovan acknowledged that another set of NCUA rules—those expanding credit union fields of membership—also were issued during a timeframe that could subject them to the Congressional Review Act.

He added, however, that he has not heard of any effort to rescind those rules, saying that CUNA was prepared to argue that the regulations help, rather than constrain credit union efforts to provide services.
