In November 2012, The FFRF filed a lawsuit against the IRS for not enforcing its own electioneering laws. The FFRF cited in its suit the placement of full page ads by the Billy Graham Evangelistic Association; the diocese requiring priests to read a statement urging Catholics to vote; and the institution of "Pulpit Freedom Sunday". The group claimed that not enforcing the federal tax codes that prohibit tax-exempt religious organizations from electioneering is a violation of the First Amendment of the Constitution. The group stated that the increasing involvement of religious institutions in politics was "blatantly and deliberately flaunting the electioneering restrictions".
