The International Union of Operating Engineers Locals 139 and 420 have filed a federal lawsuit seeking to invalidate Act 10, a law passed in 2011 that restricts collective bargaining.
The plaintiffs argue Act 10 violates free speech and free association under the First Amendment. The lawsuit states that “Act 10 is a content-based restriction infringing on Plaintiffs’ right to free speech.”
