Due to a lack of resources, the ACRU originally restricted itself to amicus briefs, having filed briefs in 15 cases by 2008. It expanded into writing on legal issues and having its spokespeople appear on talk radio and TV. When founder Carleson died in 2006, the Board of Directors elected to name his widow, Susan Carleson, a former Reagan administration official, Chairman and CEO. The ACRU filed its first amicus brief in Boy Scouts of America v. Dale, a case in which the Supreme Court decided that the Boy Scouts could not be legally forced to retain openly gay adult Scout leaders. Other issues include Bush v. Palm Beach County Canvassing Board in December 2000, the Mount Soledad cross controversy and other First Amendment cases, the District of Columbia v. HellerSecond Amendment case and an Indiana voting-rights case regarding the use of photo ID. In 2010, the ACRU filed a brief arguing that the names of signers of a Washington state petition against gay marriage should not be published, likening gay rights activists to brownshirts.

2/2/2018 ACRU files an amicus brief with the U.S. Supreme Court in North Carolina, et al., Applicants v.
