Should a question on what happens in/after 4-4 ruling in SCOTUS (Supreme Court of the United States) be asked on Politics or Law SE?
I'd consider that question to be on topic.
I'd say that it is a question about governments and how they work. It's a matter of the State, which is what "Politics" means.
I expect it to be on topic for Law.SE, but there is no rule that says that you can't ask questions that would be on topic at Law.SE
