Here is the jurisdictional statement in Harris v. McCrory.
I believe this is the first case raising issues of partisan gerrymandering to make it to the Supreme Court since Justice Scalia’s passing. Will they touch it? I don’t know. One thing that increases the odds it is that it is on appeal from a three-judge court (rather than on a totally discretionary cert. petition).
This is the case where the NC Legislature “cured” what was seen as a racial gerrymander by imposing a new plan that legislators basically admitted was a partisan gerrymander.
