In a blow to Gov. Greg Abbott, a federal judge on Thursday ruled that Texas’ S.B. 4, set to take effect on Tuesday, is unconstitutional, according to the Express-News. U.S. Judge David A. Ezra wrote in his ruling that Texas’ “Show Me Your Papers Law,” which would allow state and local authorities to detain anyone they suspected of being in the U.S. illegally, “conflicts with key provisions of federal immigration law, to the detriment of the United States’ foreign relations and treaty obligations.” What’s more, Ezra also blasted Abbott’s legal argument that migrants are invading Texas, hence allowing the state to enact certain measures in self-defense, according to the daily.
