Redistricting remedies rest on the same questionable understanding of equitable power. No court has explained
where the power to draw a replacement map comes from,
but all now assume it may be exercised as a matter of
course. The most consideration this Court has given to the
question, if it can be called consideration, was in Reynolds
v. Sims, 377 U. S. 533. In that case, the Court foreswore
any attempt to “consider . . . the difficult question of the
proper remedial devices which federal courts should utilize
in state legislative reapportionment cases,” but nonetheless
upheld, as an act of “proper judicial restraint,” the District
Court “ordering its own temporary reapportionment plan.”
Id., at 585–586. The Court’s only support for that conclusion was the naked statement in Justice Douglas’s Baker
concurrence that “ ‘any relief accorded can be fashioned in
the light of well-known principles of equity.’ ” Reynolds, 377
U. S., at 585 (quoting 369 U. S., at 250). Douglas’s statement is an obvious fallback to the “practical flexibility” extolled as a “traditional attribut[e] of equity power” in Brown
II. 349 U. S., at 300. The explanation is wholly inadequate;
the Court has never attempted to ground the map-drawing
power in “the jurisdiction in equity exercised by the High
Court of Chancery in England” in 1789. Grupo Mexicano,
527 U. S., at 318 (internal quotation marks omitted).
The lack of a historically grounded map-drawing remedy
is an enormous problem for districting claims, because no
historically supportable remedy can correct an improperly
drawn district. The most promising option is “[t]he negative injunction remedy against state officials countenanced
in Ex parte Young,” a “standard tool of equity that federal
courts have authority to entertain under their traditional
equitable jurisdiction.” Whole Woman’s Health v. Jackson,
