June 9, 2017: PPLI (along with Center for Competitive Politics) filed an amicus curiae brief in the Supreme Court of the United States supporting a request that the Court review (grant certiorari) the decision of the U.S. Court of Appeals for the Fourth Circuit in No. 16-1436, Trump v. International Refugee Assistance Project. This case, popularly known as the “travel ban” case, is an Establishment Clause challenge to President Trump’s Executive Order 13,780 temporarily halting non-immigrant admissions to the United States. PPLI and CCP filed a brief to show the Court that there was a hidden, but very important, First Amendment speech issue in the case: whether the Fourth Circuit’s proposal to “chill” certain candidates’ speech as part of an Establishment Clause review was constitutional under the free speech protections of the First Amendment.
