The Center for American Progress (CAP) unveiled its report Foreign Law Bans: Legal Uncertainties and Practical Problems at a May 16, 2013, event at CAP's Washington, DC, headquarters. CAP's analysts are unconcerned by the influence of sharia and other foreign laws in America.
CAP's event and report opposed state-level legislative efforts across the United States to implement versions of the American Law for American Courts (ALAC) model law of the American Public Policy Alliance (APPA). The text of this law voids any foreign legal decision not respecting the "same fundamental liberties, rights, and privileges granted under the U.S. and [State] Constitutions." Arizona, Kansas, Louisiana, and Tennessee have adopted such laws.
Stephen M. Gelé, a Louisiana lawyer active in his state's adoption of ALAC, explored its rationale at Breitbart. Gelé analyzed six appellate cases reviewing trial court decisions with varying results based upon troubling elements of sharia. Gelé drew upon 50 state court appellate cases involving sharia law documented in a Center for Security Policy (CSP) study.
