From Ballotpedia:
The phrase partisan gerrymandering refers to the practice of drawing electoral district maps with the intention of favoring one political party over another. On June 27, 2019, the Supreme Court of the United States issued a joint ruling in Rucho v. Common Cause and Lamone v. Benisek, finding that partisan gerrymandering claims present political questions that fall beyond the jurisdiction of the federal judiciary.
