In a 6-3 decision, SCOTUS rejected the notion that state legislatures have unlimited power to determine the rules for federal elections and draw partisan congressional maps without interference from state courts.
How much effect will this have on existing congressional maps and upcoming elections?
Unfortunately, the Supreme Court is still of the opinion that they cannot hear cases alleging partisan gerrymandering. This decision only means that the highest court of a state may be able to decide in matters of partisan gerrymandering within their state. With the Texas Supreme Court consisting of nine Republicans, I’m doubtful that many acts of the state legislature will be overturned even in cases of overtly partisan actions.
