ICBA and state community banking associations joined an industry legal brief backing the American Bankers Association’s appeal in its lawsuit against the National Credit Union Administration. The NCUA’s October 2016 final rule significantly expanded the service areas in which community credit unions can do business. A federal judge last year vacated two provisions of the rule that would have defined combined statistical areas with fewer than 2.5 million people as local communities and increased the population limit for rural districts to 1 million. ABA’s appeal challenges the court’s decision to leave in place a provision of the rule allowing credit unions to serve metropolitan areas without serving their urban core. The brief also urges the appellate court to uphold the lower court’s ruling that the NCUA rule unreasonably defines rural districts to automatically include entire states and major metro centers.
