On December 24, 2014, the Commission announced that the interim rules removing the aggregate biennial contribution limits formerly found at 11 CFR 110.5 are now final rules. (79 Fed. Reg. 77373).
The Commission undertook this rulemaking to implement the Supreme Court's recent decision in McCutcheon v. FEC holding the aggregate limits unconstitutional. See this Record article for a summary of the rulemaking.
