Rather than seeking a ban on foreign or international law, ALAC seeks to preserve the constitutional rights and state public policy protections of American citizens and legal residents, in cases involving foreign laws in the particular dispute being adjudicated.
The United States Supreme Court has cited unratified treaties (and even an African treaty), and various contemporary foreignlaw sources, as guidance for interpreting United States constitutional provisions.
What is more, it does not preclude the application of any foreignlaw, including Shariah - except insofar as it violates constitutional rights or state public policy.
If a case arises in which a foreignlaw or foreign legal doctrine is involved in a dispute in a state court, ALAC prevents the use of that foreignlaw or foreign legal doctrine if any of the parties' constitutional rights or state public policy would be violated in the process.
