In the fall of 2002, I advised the Brennan Center for Justice and the US Department of Justice on social scientific matters central to litigation over the Bipartisan Campaign Reform Act . The case was first heard by a panel of three District Court Justice and then referred automatically to the Supreme Court. Two of the three District Court judges ruled in favor of the Act. These same two judges, one a Bill Clinton appointee and the other a George W. Bush appointee, based their opinions on a careful examination of the relevant social scientific arguments including my own. The Supreme Court later affirmed these opinions. You can read their arguments here.
