Podcast: SCOTUS Oral Arguments and Opinions
Published On: Thu Jun 25 2026
Description: Overview:Four opinions released June 25th, 2026 — one day, across environmental tort preemption, immigration enforcement, executive authority over humanitarian protections, and Second Amendment rights.Three of four decisions split 6–3: identical conservative majority, identical liberal dissent, three consecutive times.The fourth — a Roundup cancer lawsuit and a $1 million-plus Missouri jury verdict — fractured the usual alliances, drawing Sotomayor and Kagan into a 7–2 conservative coalition while pushing Gorsuch into dissent alongside Jackson.Justice Alito authored three majority opinions; Justice Kavanaugh authored one; Chief Justice Roberts joined all four without writing separately.Justice Thomas wrote or joined a separate concurrence in all four cases — each one planting seeds for future constitutional challenges to the administrative state, executive immigration power, and federal equal protection doctrine.Justice Jackson dissented in all four cases — twice as the author — making her the most prolific dissenter of the opinion day.This episode breaks down all four decisions: authors, vote splits, key holdings, Thomas's concurrence roadmap, and real-world consequences.Monsanto Co. versus Durnell | No. 24–1068Federal preemption law (FIFRA) blocks state failure-to-warn tort claims requiring cancer warnings on Roundup's label beyond what the EPA approved.7–2. Justice Kavanaugh authored the majority, joined by Roberts, Thomas, Alito, Sotomayor, Kagan, and Barrett.Justice Thomas filed a concurring opinion flagging three structural concerns: FIFRA likely exceeds Congress's Commerce Clause authority; EPA's labeling power raises non-delegation problems; and agency regulations may lack Supremacy Clause status to preempt state law.Justice Jackson dissented, joined by Gorsuch.Missouri Court of Appeals reversed and remanded.Mullin, Secretary of Homeland Security, et al. versus Al Otro Lado et al. | No. 25–5An alien standing in Mexico does not "arrive in the United States" within the meaning of the INA; inspection and asylum obligations don't attach before physical border crossing.6–3. Justice Alito authored the majority, joined by Roberts, Thomas, Gorsuch, Kavanaugh, and Barrett.Justice Thomas filed a concurring opinion arguing lower courts evaded §1252(f)(1)'s classwide injunction bar through declaratory-relief labeling, and that statutes compelling the President to admit aliens would infringe inherent executive exclusion authority.Justice Sotomayor dissented, joined by Kagan and Jackson.Justice Jackson filed a separate dissenting opinion.Ninth Circuit reversed and remanded.Mullin, Secretary, Department of Homeland Security, et al. versus Doe et al. | Nos. 25–1083 & 25–1084The TPS statute bars judicial review of termination decisions; the equal protection race claim challenging Haiti's TPS termination unlikely to succeed on the merits.Justice Alito announced the judgment and delivered the Court's opinion, joined in full by Roberts, Thomas, and Kavanaugh, and except for Part III–A by Gorsuch and Barrett.Justice Thomas filed a concurring opinion arguing §1254a(b)(5)(A) bars even constitutional claims, that Bolling v. Sharpe (1954) deserves overruling, and that non-citizen immigrants hold no constitutional equal protection rights against federal immigration decisions.Justice Kagan dissented, joined by Sotomayor and Jackson.Second and D.C. Circuits reversed and remanded.Wolford et al. versus Lopez, Attorney General of Hawaii | No. 24–1046Hawaii's law prohibiting licensed carry-permit holders from carrying firearms on private property open to the public without the owner's express consent violates the Second and Fourteenth Amendments.6–3. Justice Alito authored the majority, joined by Roberts, Thomas, Gorsuch, Kavanaugh, and Barrett.Justice Barrett filed a concurring opinion — joined by Thomas and Gorsuch as to Part II–B — rejecting Hawaii's property-law framing and disqualifying both the anti-poaching and Black Code historical analogues as invalid historical support under Bruen.Justice Kagan filed a dissenting opinion.Justice Jackson filed a dissenting opinion, joined by Sotomayor.Ninth Circuit reversed and remanded.
