The Supreme Court’s Tuesday night ruling in Allen v. Milligan appears poised to give Republicans an additional U.S. House seat, shifting the political map as primaries approach in Alabama. Critics say the Court is changing key legal rules it set out just weeks
On Tuesday night. the Supreme Court handed down a decision that is expected to tilt the 2026 midterms toward Republicans by giving the Republican Party an additional seat in the U.S. House of Representatives. The vote appears to fall along partisan lines. with six Republican justices voting in the majority and the three Democrats dissenting. though not every justice publicly disclosed how they voted.
The case is Allen v. Milligan. and it sits inside a broader sweep of Supreme Court actions over the past seven years that have dismantled federal safeguards against gerrymandering. On its face. the new decision follows that same direction. steering the law toward a regime where states can draw congressional maps with fewer constraints on whether those maps advantage one political party or work to lock nonwhite voters out of power.
What has drawn sharper fire. though. is how the Court’s legal reasoning appears to shift—sometimes quickly—depending on the case. The Republican majority’s latest opinion in Allen stands out because. as Justice Sonia Sotomayor argued in her dissent. its legal arguments are inconsistent with positions the same justices took as recently as one month ago. and inconsistent with earlier orders from within the Allen litigation itself.
In Sotomayor’s dissent, she focuses on a particular break in the Court’s own rulebook: Louisiana v. Callais, decided at the end of April. That ruling completed a project that at least one member of the Court’s majority began more than four decades ago, according to the dissent.
Callais erased the effect of a key 1982 amendment to the Voting Rights Act. When President Ronald Reagan signed the Voting Rights Act amendments in 1982. the law—including the 1982 changes—barred race discrimination in elections and made it possible for many election-law challenges to succeed even without proof that a plaintiff could show a law was enacted with racist intent.
The dissent says a conservative faction inside the Reagan administration opposed those 1982 amendments and urged Reagan to veto them. and it identifies future Chief Justice John Roberts as a member of that faction. It says Roberts wrote about two dozen memos opposing the 1982 amendment and drafted speeches and talking points for senior lawyers who opposed it.
Although that faction lost in 1982. the dissent argues Roberts carried his objections forward as the political movement he was part of expanded. It says the Court’s six Republican justices in Callais joined the decision that repealed the 1982 amendment and imposed a new rule requiring plaintiffs challenging a gerrymandered map to show that state lawmakers acted with racist intent.
Sotomayor points to how the dissent describes that new standard: a plaintiff may prevail “when the circumstances give rise to a strong inference that intentional discrimination occurred.”
But in Allen, a three-judge panel—including two Trump-appointed judges—found in a 571-page opinion in 2023 that the Alabama congressional maps could not be understood “as anything other than an intentional effort to dilute Black Alabamians’ voting strength.”
The dissent says after Callais, the Supreme Court ordered the panel to reconsider its ruling. It says the panel did not change its mind, concluding again that Alabama engaged in intentional race discrimination.
To explain that conclusion. the dissent points to what the lower court described as the way the 2023 Alabama law structured the map. It says Alabama’s map plan achieved its racial goals by keeping together a majority-white area called the Gulf Coast while dividing a Black-majority region called the Black Belt.
And the dissent says Alabama’s own law wrote those intentions into statute. It points to language requiring that the Gulf Coast “shall be kept together to the fullest extent possible. ” and says Alabama lawmakers explained that goal in part as an effort to preserve “distinct culture stemming from its French and Spanish colonial heritage.”.
In the dissent’s telling. that means lawmakers in Alabama wrote into law a plan to preserve a European American region’s ability to elect its preferred representative while breaking up an African American region. The dissent argues that if that doesn’t create a strong inference of intentional discrimination, “nothing does.”.
Yet the Republican majority’s new Allen opinion is described as only four pages long. and Sotomayor says it responds with a single sentence to the hundreds of pages of evidence the lower court compiled. The dissent says the Republican justices argued that the lower court “did not heed the presumption of legislative good faith” judges are supposed to apply to state lawmakers accused of race discrimination.
The timeline then becomes part of the argument. Sotomayor says that just over one month after the Court’s Republicans set out a standard in Callais allowing racial gerrymandering claims to proceed when there is a strong inference of intentional discrimination. the same justices appeared to abandon that approach in Allen. The dissent says the outcome is an extra House seat for Republicans.
Sotomayor also says the Court’s position in Allen is not consistent with how the Court previously ruled in the same case. She highlights the way Callais described its relationship to Allen. The dissent says that in Callais. the Republican justices explicitly stated that “we have not overruled Allen. ” referring to the Supreme Court’s 2023 decision in Allen.
But Sotomayor’s dissent argues that the Court’s later actions show that the 2023 ruling in Allen was effectively supplanted. She says the 2023 Allen decision held that Alabama must draw maps with at least two Black congressional districts. while the 2026 ruling in Allen—issued in Tuesday night’s decision—held that Alabama does not need to include those two Black districts after Callais. In her view, Callais overruled the 2023 opinion in Allen.
The dissent adds another urgent concern: timing. Sotomayor warns that the Court’s latest Allen decision is likely to cause “chaos” in Alabama’s upcoming congressional election. She says the primaries are scheduled for August 11. leaving Alabama little time to complete the time-consuming task of reviewing each voter’s record to ensure voters are assigned to the correct district.
Sotomayor also traces Alabama’s past argument about timing. She says that after a federal district court struck down an earlier version of Alabama’s maps in 2022. Alabama told the Supreme Court that it needed to block that decision because the district court issued it four months before a primary. and “four months was not enough time to change congressional maps.” The dissent says Republican colleagues agreed with that argument.
She points to warnings made by two justices when the Supreme Court agreed to block the 2022 decision. The dissent says they warned the lower court’s order would require “heroic efforts” by state and local authorities in the next few weeks. and that even those efforts likely would not be enough to avoid chaos and confusion.
Sotomayor’s contrast is sharp in the dissent’s framing. She says that when a lower court decision would have benefited the Democratic Party by requiring Alabama to draw a map that would elect an additional Black Democrat. the Court’s Republican justices appeared to accept the claim that four months wasn’t enough. Now. she says. the Court appears to believe the state can do the same kind of “heroic efforts” in only two months.
For all of that. the dissent acknowledges a limit on how easy it is to reduce Supreme Court behavior to party loyalty. It says the Court’s Republicans have sometimes ruled against their own party when they believed the arguments were weak. It points to 2020. when the Supreme Court rejected President Donald Trump’s attempt to overturn his loss to former President Joe Biden.
The dissent argues that granting Trump the victory would have required the Court to overturn election results in three different states. calling that effort too much for this Supreme Court. It then adds that the Supreme Court in 2024 held that Trump is allowed to use the powers of the presidency to commit crimes.
In the end. Sotomayor’s view is that the Court’s Republican justices are putting a thumb on the scale of the 2026 midterms. She describes the most reasonable explanation as an intent to give the Republican Party an advantage—an advantage she says the justices pursue even if it means contradicting their own past decisions.
Tuesday night’s decision changes the map again. and with Alabama’s August 11 primaries looming. the stakes are no longer abstract. The Court’s shift in legal standards and its impact on district lines will reach straight into election administration—where time. paperwork. and voter assignments can decide whether the political promises on paper hold up in real life.
