6 ABBOTT v. PEREZ Opinion of the Court the interest of the collective public good.” Id., at 212.5 Texas challenged those court-ordered plans in this Court, and we reversed. Perry v. Perez, 565 U. S. 388 (2012) (per curiam). Noting that “[r]edistricting is ‘primarily the duty and responsibility of the State,’ ” we held that the Texas court should have respected the legislative judgments embodied in the 2011 plans to the extent allowed by the Constitution and the VRA. Id., at 392–399. We remanded the case with very specific instructions. The Texas court was told to start with the plans adopted by the Legislature but to modify those plans as needed so as “not to incorporate . . . any legal defects.” Id., at 394. With respect to claims under the Constitution or §2 of the VRA, the District Court was told to change a district if the plaintiffs were likely to succeed on the merits of their challenge. Ibid. And with respect to §5 claims, the court was instructed to make whatever changes were needed to obviate any legal claim that was “not insubstantial.”6 Id., at 395. Thus, our instructions, in an abundance of caution, demanded changes in the challenged 2011 plans without proof that those changes were actually required by either the Constitution or the VRA. On remand, the Texas court ordered additional briefing and heard two more days of argument. App. 29a, 35a– 50a; Order in Civ. No. 11–cv–00360, Doc. No. 616. It issued two opinions, totaling more than 70 pages, and analyzed disputed districts in detail. C. J. S. 367a–423a; —————— 5 Judge Smith dissented, arguing that the majority had produced a “runaway plan” that “award[ed] judgment on the pleadings in favor of one side—a slam-dunk victory for the plaintiffs.” Perez v. Perry, 835 F. Supp. 2d 209, 218 (WD Tex. 2011). 6 The Texas court was given more leeway to make changes to districts challenged under §5 because it would have been inappropriate for that court to address the “merits of §5 challenges,” a task committed by statute to the District Court for the District of Columbia. Perez, 565 U. S., at 394.
