Maryland's redistricting history provides concerning precedent for map proponents.

Implications for Supreme Court Redistricting Jurisprudence

Maryland's case exists within a complex and evolving federal judicial framework that has significant implications for how future redistricting challenges will be adjudicated.

The Rucho Framework and State Court Primacy

The U.S. Supreme Court's 2019 decision in Rucho v. Common Cause established that "partisan gerrymandering claims present political questions beyond the reach of the federal courts," effectively closing federal courthouse doors to challenges based solely on partisan manipulationRucho v. Common Cause | Oyezoyez +1. Chief Justice Roberts's majority opinion explicitly directed that state courts and state constitutions remained available forums: "provisions in state statutes and state constitutions can provide standards and guidance for state courts to apply"The Court Is Likely to Reject the Independent State Legislature Theorytheatlantic .

This framework was reinforced by Moore v. Harper (2023), which rejected the independent state legislature theory and confirmed that "state courts retain the authority to apply state constitutional restraints when legislators act under the power conferred upon them by the Elections Clause"21-1271 Moore v. Harper (06/27/2023)supremecourt +1. The decision explicitly held that "the Elections Clause does not insulate state legislatures from the ordinary exercise of state judicial review"Moore v. Harper - Harvard Law Reviewharvardlawreview .

However, Moore also introduced a significant caveat: federal courts retain "an obligation to ensure that state court interpretations of state law do not evade federal law" and that "state courts may not transgress the ordinary bounds of judicial review such that they arrogate to themselves the power vested in state legislatures to regulate federal elections"21-1271 Moore v. Harper (06/27/2023)supremecourt . The Court declined to articulate a specific standard for when state courts exceed these bounds, leaving significant uncertaintyMoore v. Harper - Harvard Law Reviewharvardlawreview .

The Racial-Partisan Gerrymandering Distinction

The Supreme Court's 2024 decision in Alexander v. South Carolina State Conference of the NAACP significantly raised the evidentiary bar for proving racial gerrymandering claims. The 6-3 ruling established that courts must presume "legislative good faith" when evaluating redistricting challenges and that plaintiffs lacking "direct evidence of a predominant racial motive" must produce alternative maps demonstrating that partisan objectives could be achieved "with significantly greater racial balance"Alexander v. South Carolina State Conference of the NAACP - Wikipediawikipedia +1.

Justice Alito's majority opinion emphasized the difficulty of "disentangling race and politics" where "race and politics are highly correlated," concluding that circumstantial evidence suggesting racial motivation was insufficient when it "could readily be explained by partisan goals"Supreme Court Clarifies Evidentiary Contours of Racial ...swlaw +1.

Justice Kagan's dissent warned that the decision "gives anyone who wants to gerrymander, Republican or Democrat, the roadmap for getting away with it. Cloak it in politics, just say that's the reason you made the decisions you did, and you are good to go"Justices Alito and Thomas' Ruling Raises Questions of Favoritism: Attorneynewsweek .

Louisiana v. Callais: The Pending Watershed

The most consequential pending case for redistricting jurisprudence is Louisiana v. Callais, currently before the Supreme Court with oral arguments held in October 2025Louisiana v. Callais (Voting Rights Act) - SCOTUSblogscotusblog . The Court has directed supplemental briefing on "whether the State's intentional creation of a second majority-minority congressional district violates the Fourteenth or Fifteenth Amendments to the U.S. Constitution"—a question that directly challenges the constitutionality of Section 2 of the Voting Rights ActLouisiana v.

A ruling weakening or invalidating Section 2's mandate for majority-minority districts could fundamentally reshape redistricting nationwide.

How Maryland Could Shape Future Precedent

Maryland's case presents unique characteristics that could influence Supreme Court jurisprudence in several ways:

State Constitutional Standards Post-Rucho

Maryland represents one of the most fully developed state constitutional frameworks for challenging partisan gerrymandering. Judge Battaglia's 2021 ruling established that extreme partisan gerrymandering violates multiple provisions of the Maryland Declaration of Rights—a holding that created binding precedent at the trial court level but was never reviewed by Maryland's highest court because appeals were withdrawn when a new map was adoptedState redistricting expert warns governor's redistricting panel of lawsuit 'the state will lose' - Maryland Mattersmarylandmatters .

If the current map is enacted and challenged, the Maryland Supreme Court would have its first opportunity to definitively interpret whether the state constitution prohibits partisan gerrymandering. At least ten state supreme courts have now found that state courts can adjudicate partisan gerrymandering claims, though four—Kansas, Nevada, New Hampshire, and North Carolina—have ruled such claims non-justiciable under their state lawsStatus of Partisan Gerrymandering Litigation in State Courts | Brennan Center for Justicebrennancenter .

A Maryland ruling could join decisions from Alaska, New Mexico, New York, and Ohio that have recognized partisan gerrymandering claims as justiciable under state constitutionsRedistricting Litigation Roundup - Brennan Center for Justicebrennancenter . Conversely, if the Republican-majority court declines to strike down the map or finds such claims non-justiciable, it could strengthen the hand of legislatures nationwide.

Testing the Limits of Moore v. Harper

Any Maryland Supreme Court ruling on the proposed map could become a vehicle for testing the undefined limits articulated in Moore v. Harper. The Supreme Court's statement that state courts may not "transgress the ordinary bounds of judicial review" left substantial ambiguity about what federal courts would consider transgressiveHow John Roberts—Yes, John Roberts—Might Decide Who Won the Electionnewrepublic .

If the Maryland Supreme Court strikes down the proposed map as unconstitutional under state law, Republican legislators could potentially seek U.S. Supreme Court review arguing that the state court exceeded its proper role. This would force the federal Court to finally articulate a standard for federal review of state court redistricting decisions—a question it explicitly declined to answer in MooreMoore v. Harper - Harvard Law Reviewharvardlawreview .

Justice Kavanaugh's Moore concurrence signaled openness to developing "a more specific standard" for federal court review, suggesting that a future case could provide the vehicleHow John Roberts—Yes, John Roberts—Might Decide Who Won the Electionnewrepublic .

Partisan Gerrymandering as Constitutional Defense

Maryland's case could also test whether compliance with state anti-gerrymandering standards creates a shield against federal constitutional claims. Under the Alexander framework, states can defend race-conscious districting by demonstrating partisan rather than racial motivationSupreme Court Clarifies Evidentiary Contours of Racial ...swlaw . Maryland's map proponents have explicitly characterized their goals in partisan terms—Representative C.T. Wilson stated the map is "not about getting eight Democrats. It's about getting eight congressmen... to stand up against this poorly veiled autocratic kleptocracy"Maryland House approves Democrat-leaning Congressional map, Senate not likely to vote | WYPRwypr .

However, if a state court finds the same map violates state constitutional standards against partisan gerrymandering, it would create tension between federal doctrine permitting partisan redistricting and state law prohibiting it—potentially forcing the Supreme Court to clarify how these competing frameworks interact.

Ferguson's Opposition and Strategic Calculation

Senate President Ferguson's resistance to the redistricting effort reflects a sophisticated legal and political calculation. In his letter to Democratic colleagues, Ferguson warned that mid-cycle redistricting "presents a reality where the legal risks are too high, the timeline for action is dangerous, the downside risk to Democrats is catastrophic, and the certainty of our existing map would be undermined"MD redistricting bill passes House, faces tougher test in Senatethedailyrecord .

Ferguson's concerns center on several factors:

Third, Ferguson has characterized the proposed map itself as constitutionally deficient, stating it "fails the Governor's own test.

Conclusion: Marginal National Impact, Potentially Significant Legal Consequences

Maryland's proposed redistricting map, if enacted, would contribute modestly to the national partisan balance—one seat in a chamber of 435 where control hinges on margins of fewer than five seats. Its practical impact would depend on whether Democrats can convert the structural advantage into electoral victories and whether the map survives judicial scrutiny.

The legal implications could prove more durable. A Maryland Supreme Court ruling on partisan gerrymandering would add to the growing body of state constitutional law developed in response to Rucho's closure of federal courts. Whether the court strikes down or upholds the map, the decision would provide guidance to other states with similar constitutional provisions and could potentially become a vehicle for the U.S. Supreme Court to further define the limits of state court redistricting review under Moore v. Harper.

The interaction between Maryland's litigation and the pending Louisiana v. Callais decision adds another layer of uncertainty. If the Supreme Court significantly weakens Section 2 of the Voting Rights Act, it could reshape the legal landscape for both majority-minority districts and the broader question of what constitutional constraints apply to redistricting—potentially affecting how courts evaluate Maryland's map and similar challenges nationwideSection 2 of the Voting Rights Act at the Supreme Court | Brennan Center for Justicebrennancenter +1.
