Even if the US Supreme Court has punted on this, it appears that state courts are increasingly ruling against the practice:

A North Carolina court ruled Tuesday that the state’s legislative districts are unconstitutional, in a unanimous decision that won praise from voting-rights advocates and opens a new front in the national battle over partisan gerrymanders.

The three superior court judges in Wake County set a deadline of Sept. 17 by which North Carolina’s Republican-led General Assembly must submit redrawn state House and Senate district maps to be reviewed by a court-appointed referee.

In their ruling, the judges stated that the plaintiffs had proved the effect of the “partisan” maps drawn by the state legislature was that, “in all but the most unusual election scenarios, the Republican party will control a majority of both chambers of the General Assembly.”

“In other words, the Court finds that in many election environments, it is the carefully crafted maps, and not the will of the voters, that dictate the election outcomes in a significant number of legislative districts and, ultimately, the majority control of the General Assembly,” the judges said in their ruling.
