A law banning politically motivated apparel and accessories inside polling places is overbroad and violates the First Amendment. Decided June 14, 2018 (argued February 28, 2018). Opinion of the Court: John Roberts → go there Dissenting: Sotomayor. Topic: Freedom of speech and of the press. Minnesota Voters Alliance v. Mansky, 585 U.S. 1 (2018), is a landmark decision of the US Supreme Court concerning the constitutionality of governmental speech restrictions in a polling place venue. The case challenged a century-old Minnesota law that prevents voters from wearing clothing or items considered political while voting. While the Supreme Court previously ruled that political campaigning near polling places may be restricted, the Minnesota law was challenged as overbroad and violative of free speech rights under the First Amendment. On June 14, 2018, the Court ruled by a 7–2 vote that the Minnesota law was overbroad and violated free speech rights and was therefore unconstitutional. Wiki link
