WASHINGTON — The Supreme Court declined on Monday to address the central questions in two closely watched challenges to partisan gerrymandering, putting off for another time a ruling on the constitutionality of voting districts designed by legislatures to amplify one party’s political power.
In a challenge to a redistricting plan devised by the Republican Legislature in Wisconsin, the court unanimously said that the plaintiffs had not proved that they had suffered the sort of direct injury that would give them standing to sue. The justices sent the case back to a trial court to allow the plaintiffs to try again to prove that their voting power had been directly affected by the way state lawmakers drew voting districts for the State Assembly.
In the second case, the court unanimously ruled against the Republican challengers to a Democratic plan to redraw a Maryland congressional district. In a brief unsigned opinion, the court said the challengers had waited too long to seek an injunction blocking the district, which was drawn in 2011.
Both cases had the potential to deliver a reckoning on a practice that dates to the early days of the Republic and got its name from one of the signers of the Declaration of Independence, Elbridge Gerry. The court instead kicked the can down the road, leaving the door open to further challenges.
