Pro bono representation of the congressional co-sponsors of the Bipartisan Campaign Reform Act (BCRA) in federal district and appellate court litigation challenging as inadequate various regulations promulgated by the Federal Election Commission, including those dealing with coordinated campaign communications. The D.C. Circuit found that several of the challenged regulations frustrated BCRA’s purpose of closing the soft money loophole in federal campaign law and were arbitrary and capricious under the Administrative Procedure Act. 414 F.3d 76 (2005); 528 F.3d 914 (2008).
