Within days of the U.S. Supreme Court hearing a challenge to an Arizona voting registration law that had been adopted as a “model” by the American Legislative Exchange Council (ALEC), two more states advanced bills that appear to track the ALEC/Arizona template.

On March 18, the Supreme Court heard oral arguments in Arizona v. Inter Tribal Council of Arizona (ITCA), which will decide whether Arizona’s refusal to register voters that do not provide proof of citizenship is in conflict with federal law.

As the Center for Media and Democracy reported, the 2004 Arizona law at issue in the case was subsequently adopted by ALEC lobbyists and legislators as a “model” for other states under the name the Taxpayer and Citizen Protection Act. The ALEC/Arizona law requires voters submit a copy of documents like passports or birth certificates to register, and is being challenged in the Supreme Court on grounds that it imposes additional restrictions beyond the National Voter Registration Act, which requires states to accept registrations submitted on a uniform federal mail application. Over 31,000 eligible Arizona voters have been rejected from the rolls because they did not have the additional documentation required under the state law.

The ALEC Taxpayer and Citizen Protection Act has since been introduced in multiple states, most recently in South Carolina and Nevada.
