The American Civil Liberties Union and other partner organizations filed a federal lawsuit challenging President Trump’s Muslim ban executive order, charging it violates the Constitution — including the First Amendment’s prohibition of government establishment of religion and the Fifth Amendment’s guarantees of equal treatment under the law — and federal laws.

The lawsuit was brought by the ACLU, ACLU of Maryland, and National Immigration Law Center on behalf of HIAS, the International Refugee Assistance Project at the Urban Justice Center, Middle East Studies Association, along with individuals, including U.S. citizens, affected by the ban. The complaint was filed in U.S. District Court in Maryland. 

The American Civil Liberties Union and partners amended their existing lawsuit to encompass claims against President Trump’s proclamation, announced on September 24, which blocks travel to the United States from six predominantly Muslim countries, but also includes North Koreans and certain Venezuelan government officials. The Yemeni American Merchants Association and the Arab American Association of New York have joined the ACLU’s lawsuit as plaintiffs. 

On Oct. 18, a federal district court in Maryland blocked President Trump’s newest Muslim ban from taking effect. A federal court in Hawaii issued a similar ruling a day earlier in a separate challenge.  The Trump adminstration appealed, with the ACLU case being heard on Dec. 8 by the Fourth Circuit Court of Appeals in Virginia. 

Update (6/26/18): In a 5-4 ruling, the Supreme Court has upheld the Trump administration’s third Muslim ban.
