539 P.3d 272
N.M.2023Background
- In a December 2021 special legislative session New Mexico enacted a congressional map over the Citizen Redistricting Committee’s recommended plans; Real Parties (Republican Party and individual Republicans) sued, alleging the map is an unconstitutional partisan gerrymander that dilutes Republican votes by packing/cracking.
- Real Parties sought a declaration the map violated Article II, Section 18 (state Equal Protection) and asked for a preliminary injunction replacing the map with a partisan-neutral map (map E); the district court denied the injunction and refused to dismiss the suit.
- Petitioners (Governor, legislative leaders) sought a writ of superintending control and stay from the New Mexico Supreme Court to resolve (1) whether Article II, Section 18 provides a remedy for partisan gerrymandering, (2) whether such claims are justiciable, and (3) what standards apply.
- The Supreme Court stayed the district-court proceedings, exercised superintending control, and ruled that partisan-gerrymandering claims are justiciable under the New Mexico Constitution and provided standards and guidance for the district court.
- The Court adopted Justice Kagan’s three-part test (intent, effects, causation) for adjudicating partisan-gerrymandering claims under Article II, Section 18, held intermediate scrutiny applies, and required district-specific evidence of packing or cracking for the effects prong.
- The Court declined to resolve the precise quantitative threshold of impermissible partisan bias at this interlocutory stage and resolved that the case should be decided under the state constitution rather than via Gomez interstitial analysis relying on federal precedent.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Cognizability: Does Art. II §18 provide a remedy for partisan gerrymandering? | Maestas and state protections allow judicial relief for vote-dilution partisan gerrymanders. | Rucho and separation-of-powers counsel federal nonjusticiability or coextensiveness with federal Equal Protection. | Yes — New Mexico Constitution affords a remedy for egregious partisan gerrymanders. |
| Justiciability / political-question: Is a partisan-gerrymandering claim justiciable? | Courts must vindicate individual voting rights; political-question prudential concerns do not bar review. | Such claims are political and nonjudiciable (Rucho); standards are lacking. | Justiciable under state constitution; federal political-question prudential rules are persuasive but not binding. |
| Choice of law: Should Gomez interstitial analysis be applied or should the Court decide under state law? | Either federal protection exists or Gomez prongs support divergence from federal precedent. | Federal law controls; Gomez prongs not met. | Decide under Article II §18 alone—Gomez not applied—because federal scope is undetermined. |
| Standard of review & evidence: What test and burden apply, and what proof is required? | Adopt Maestas/Redistricting Act or federal tests; plaintiffs can rely on statewide patterns and seek injunction. | Rucho shows no manageable standard; injunction disruptive. | Apply Kagan three-part test (intent, effects, causation); intermediate scrutiny; plaintiffs must show district-specific packing/cracking causing substantial vote dilution; State may proffer legitimate nonpartisan justification. |
