The National Credit Union Administration has asked a judge to dismiss key parts of a lawsuit challenging the agency's new membership rule.

In a brief filed April 15, the credit union regulator urged U.S. District Court Judge Colleen Kottar-Kotelly to dismiss most of the counts lodged by the American Bankers Association in an April 1 amended complaint. The NCUA said some of the counts are "not ripe for judicial consideration."

Its co-defendant, the Credit Union National Association, filed a separate brief Thursday.

The ABA filed an initial complaint Jan. 12, but seven of the eight counts were dismissed by Judge Kotelly. The trade group then filed an amended complaint. Two other parties-the Independent Community Bankers of America and a New York credit union-are co-plaintiffs in the lawsuit.

Most provisions of the NCUA's membership rule went into effect in January; two key parts became effective in March.
