Key Decisions: Patriot University Domains

Executive Power

Trump v. United States (2024) — 6-3; Kavanaugh joined the majority Joined the presidential immunity decision. Kavanaugh’s background in both the Starr investigation (investigating a president) and the Bush White House (defending presidential prerogatives) gives him a distinctive dual perspective on executive power questions. His vote for broad immunity represents a departure from the investigative posture he took as a Starr attorney — though he would argue the constitutional question is different from the prosecutorial judgment.

Trump v. Thompson (2022) — 8-1; Kavanaugh joined the majority but wrote separately Voted to deny Trump’s bid to block January 6 Committee documents. However, Kavanaugh wrote a separate statement disagreeing with the appeals court’s reasoning — specifically arguing that a former president’s executive privilege claim should be given more weight than the lower court suggested, even when the sitting president opposes it. This concurrence attempted to protect future executive privilege claims while allowing the immediate release.

Trump v. Hawaii (2018) — 5-4; Kavanaugh was NOT on the Court for this decision (confirmed October 2018).

Voting Rights

Allen v. Milligan (2023) — 5-4; Kavanaugh joined Roberts and the liberals Kavanaugh was the decisive fifth vote upholding VRA Section 2 against Alabama’s racially discriminatory redistricting map. He wrote a separate concurrence narrowing the holding — emphasizing that the Court was simply applying existing Gingles precedent and leaving open whether the framework should be modified in future cases.

This is Kavanaugh’s most significant break from the conservative bloc in PU domains. His concurrence, however, suggests the break may be temporary — he applied existing precedent but signaled openness to changing it.

Brnovich v. DNC (2021) — 6-3; Kavanaugh joined the majority Voted to narrow VRA Section 2 protections.

Louisiana v. Callais (2026) — 6-3; Kavanaugh joined the majority Voted with the majority striking down the second majority-Black district, despite having joined the VRA-protective side in Allen v. Milligan three years earlier.

Rucho v. Common Cause (2019) — 5-4; Kavanaugh joined the majority Voted that partisan gerrymandering claims are non-justiciable.

Birthright Citizenship (OT2025)

Trump v. Barbara (2026) — 6-3; Kavanaugh concurred in judgment on statutory grounds only Kavanaugh agreed the executive order was unlawful but declined to join the five-justice constitutional majority. He wrote separately that the Immigration and Nationality Act grants birthright citizenship, and Congress could change it legislatively — but the 14th Amendment does not necessarily require it. “Congress could — consistent with the Fourteenth Amendment — amend [the INA] or otherwise enact new legislation establishing exceptions to birthright citizenship for children born to foreign citizens unlawfully or temporarily in the country. But Congress has not yet done so.”

This is the most revealing single opinion Kavanaugh wrote this term. He reached the anti-administration result while explicitly preserving a future legislative pathway to restrict birthright citizenship — the definition of pragmatic minimalism.

Constitutional Veracity Assessment

Kavanaugh’s central claim — that Congress could restrict birthright citizenship “consistent with the Fourteenth Amendment” — is constitutionally untenable under both the Amendment’s text and 128 years of binding precedent. Five independent lines of analysis converge on this conclusion:

1. The Citizenship Clause is self-executing and unconditional.

The 14th Amendment, Section 1 reads: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.” The operative verb is declarative — “are,” not “may be” or “shall be as Congress provides.” This is a constitutional guarantee of status, not a delegation of power to Congress. Unlike provisions that say “Congress shall have the power to…” (Article I, §8; Amendment XIV, §5), the Citizenship Clause states a rule that applies directly. Congress cannot override a self-executing constitutional right by ordinary legislation any more than it could repeal the First Amendment by statute.

2. Wong Kim Ark (1898) established a closed set of exceptions that Congress cannot expand.

The Supreme Court held in United States v. Wong Kim Ark, 169 U.S. 649 (1898), that “subject to the jurisdiction thereof” means amenable to U.S. governing authority — which includes virtually everyone on American soil. The Court identified exactly four exceptions derived from English common law: children of (1) accredited foreign diplomats, (2) invading hostile forces, (3) passengers on foreign public ships, and (4) members of Indian tribes maintaining separate political allegiance. The Court explicitly rejected the “allegiance” interpretation that would have excluded children of foreign nationals. This holding has been binding precedent for 128 years, was never overruled, and was explicitly reaffirmed by the Barbara majority.

3. The Barbara majority already foreclosed Kavanaugh’s roadmap.

Five justices held that the 14th Amendment itself — not merely a statute — makes these children citizens. By constitutionalizing the question, the majority placed birthright citizenship beyond legislative reach. As the AILA legal analysis noted: “Any bill promising to redefine birthright citizenship by ordinary legislation is posturing, because the Constitution now answers the question, and Congress cannot amend the Constitution by statute.” Kavanaugh’s suggestion that Congress could create “new exceptions” is directly contradicted by the majority opinion he concurred alongside.

4. Section 5 enforcement power cannot narrow Section 1 rights.

If Kavanaugh’s theory rests on Congress’s §5 enforcement power, City of Boerne v. Flores, 521 U.S. 507 (1997) forecloses it. The Court held: “Congress does not enforce a constitutional right by changing what the right is. It has been given the power ‘to enforce,’ not the power to determine what constitutes a constitutional violation.” Section 5 is remedial and preventive only — it cannot be used to contract rights that Section 1 guarantees. Legislation that removes citizenship from persons the Constitution says are citizens is not “enforcing” the 14th Amendment; it is contradicting it.

5. The Amendment’s own history forecloses the statutory theory.

The Citizenship Clause exists precisely because the Reconstruction Congress feared a future Congress would repeal the Civil Rights Act of 1866 — which first granted citizenship to freedmen by statute. Senator Jacob Howard, who drafted Section 1, stated that constitutional protection was necessary because “a law is repealable by a majority.” The 14th Amendment was ratified specifically to take citizenship out of Congress’s hands and place it in the Constitution. Kavanaugh’s argument — that birthright citizenship is fundamentally statutory rather than constitutional, and therefore within Congress’s power to modify — is exactly the vulnerability the Amendment was designed to foreclose. It inverts the Amendment’s purpose.

6. The identical-language impossibility.

Kavanaugh acknowledges that 8 U.S.C. §1401(a) uses identical language to the 14th Amendment (“born in the United States, and subject to the jurisdiction thereof”) and that this statutory language — interpreted through Wong Kim Ark — includes children of undocumented immigrants. He strikes down the executive order on this basis. But he simultaneously claims the identical constitutional language does not necessarily protect those same children. The same phrase cannot mean one thing when Congress writes it and another when the Constitution contains it — particularly when the statute deliberately adopted the constitutional phrase to track its meaning.

Inferred Intent

Kavanaugh’s concurrence attracted immediate attention from Republican senators, and its political function is discernible from its structure:

1. Legislative roadmap. By stating explicitly that Congress “could” restrict birthright citizenship, Kavanaugh is telling Republican legislators they need not pursue a constitutional amendment (Article V, requiring two-thirds of both chambers and three-fourths of states) — they merely need a statute (simple majorities). This lowers the political barrier from insurmountable to achievable. The statement was immediately cited by Republican members of Congress as authorization for legislative action.

2. Future litigation vehicle. If Congress passes a statute restricting birthright citizenship based on Kavanaugh’s invitation, there are already four sitting justices (Kavanaugh + Thomas + Alito + Gorsuch) who have signaled they would uphold it. The resulting litigation would need only one more vote — perhaps from a future appointee, or from Barrett if the question were presented differently — to overturn or narrow Barbara‘s constitutional holding.

3. De facto dissent disguised as concurrence. Kavanaugh concurred in the judgment (striking down the executive order) but dissented on the constitutional holding (that the 14th Amendment requires birthright citizenship). By framing this as “concurrence” rather than dissent, Kavanaugh maintains the appearance of independence from the Trump administration while substantively aligning with Thomas, Alito, and Gorsuch on the constitutional question. The vote count on constitutionality is 5-4, not 6-3 — and Kavanaugh is on the losing side.

4. Consistent with the Kavanaugh pattern. This is the identical structure seen in Cook: reach the anti-administration result on narrow grounds while preserving the conservative legal movement’s ability to achieve the same policy goal through a different mechanism. The Barbara concurrence says: “You can’t do this by executive order — but I’m telling you Congress can do it by statute, and I’ll vote to uphold that statute when it arrives.” This is not independence; it is sequencing — constraining executive unilateralism while preserving legislative options for the same political coalition.

Bottom line: Kavanaugh’s claim is constitutionally wrong under the majority’s holding, Wong Kim Ark, City of Boerne, and the Amendment’s ratification history. Its function is political, not legal — it provides a roadmap to a destination the Constitution does not permit without the five-justice majority being overruled.

Separation of Powers and Agency Independence (OT2025)

Trump v. Slaughter (2026) — 6-3; Kavanaugh joined the majority Kavanaugh voted to overrule Humphrey’s Executor and grant the president at-will removal authority. His vote is consistent with his longstanding D.C. Circuit-era writing on executive power and agency structure.

Trump v. Cook (2026) — 5-4; Kavanaugh joined the majority protecting the Fed Kavanaugh crossed over to join Roberts, Sotomayor, Kagan, and Jackson in protecting Federal Reserve Governor Lisa Cook from removal. This is the most significant Kavanaugh-Roberts alignment of the term — both joined the liberals to protect the Fed while dismantling other agency protections on the same day. Kavanaugh wrote a concurrence noting that “the ultimate decision about whether the president may remove Governor Cook for cause will largely depend on the facts” — again preserving future flexibility while siding with institutional protection in the immediate case.

Situational ruling assessment: Kavanaugh is (alongside Roberts) one of two justices who joined BOTH the Slaughter majority (Article II requires at-will removal of officers exercising executive power) AND the Cook majority (the Fed’s “unique historical status” creates an exception). This means Kavanaugh endorsed a constitutional principle in the morning and declined to apply it in the afternoon. The internal contradiction is the same one identified in Roberts’s profile: Slaughter rejects tradition and consequentialist arguments for preserving agency independence, while Cook relies on precisely those arguments to preserve the Fed. Kavanaugh’s concurrence — explicitly reserving the “cause” question for future factual development — reveals awareness of the logical tension; he attempts to resolve it by narrowing Cook to its procedural holding (notice and opportunity to be heard) rather than endorsing the majority’s broader “unique historical status” language. But Kavanaugh’s full joinder of Roberts’s majority opinion means he cannot cabin Cook to procedure alone. His vote in both cases makes him a co-author of the situational constitutionalism the Slaughter/Cook pairing represents.

Learning Resources v. Trump (2026) — 6-3; Kavanaugh joined the majority Joined the opinion striking down Trump’s tariffs on statutory grounds.

Loper Bright v. Raimondo (2024) — 6-3; Kavanaugh joined the majority Voted to overrule Chevron deference.

Biden v. Nebraska (2023) — 6-3; Kavanaugh joined the majority Voted to block student loan forgiveness.

Campaign Finance and Civil Rights (OT2025)

NRSC v. FEC (2026) — 6-3; Kavanaugh authored the majority opinion Kavanaugh wrote the opinion striking down coordinated party expenditure limits, overruling the 2001 Colorado II precedent. He held the limits “impose a severe and direct restriction on free speech and infringe fundamental First Amendment values” and are “not ‘necessary’ and ‘narrowly tailored'” to the government’s anti-circumvention interest. This is Kavanaugh’s most consequential majority opinion in PU domains — it allows unlimited coordinated spending between parties and candidates, with only contribution limits, earmarking rules, and disclosure requirements remaining as checks.

West Virginia v. B.P.J. / Little v. Hecox (2026) — 6-3 (Equal Protection), 9-0 (Title IX); Kavanaugh authored the majority opinion Kavanaugh wrote the opinion holding that state bans on transgender athletes in female sports teams violate neither Title IX nor the Equal Protection Clause. The unanimous Title IX holding was narrow; the 6-3 Equal Protection holding applied intermediate scrutiny and found the state’s interests in safety and competitive fairness were substantially related to the sex-based classification.

First Amendment

Murthy v. Missouri (2024) — 6-3; Kavanaugh joined Barrett’s majority Voted that the plaintiffs lacked standing to challenge government communications with social media companies. This put Kavanaugh on the opposite side from Alito, Thomas, and Gorsuch, who argued the government’s contacts constituted unlawful jawboning.

Ideology vs. Politics: The Honest Assessment

The Case for Pragmatic Conservatism

Kavanaugh’s record shows more alignment with Roberts than with Thomas or Alito:

• Allen v. Milligan: Joined Roberts and the liberals to protect VRA Section 2 — a significant break
• Murthy v. Missouri: Joined the majority finding no standing in the government-social media case, breaking from the Alito-Thomas-Gorsuch dissent
• Trump v. Thompson: Voted against Trump’s privilege claim, though with a narrowing concurrence
• He voted with Barrett more frequently than any other justice (91% agreement in the 2024-25 term)

This pattern suggests Kavanaugh operates as a pragmatic conservative — conservative in orientation but willing to apply existing precedent faithfully and break from the hardliners when he perceives the law requires it.

The Case for Strategic Positioning

Critics note that Kavanaugh’s breaks are often narrow and provisional:

• His Allen v. Milligan concurrence explicitly preserved the option to change the Gingles framework in future cases — and he subsequently voted against VRA claims in Louisiana v. Callais
• His Trump v. Thompson concurrence protected future executive privilege claims while allowing the immediate document release
• He rarely writes boldly in PU domains — his opinions tend to be narrow, fact-specific, and hedged, leaving maximum flexibility for future cases

Under this reading, Kavanaugh is less a principled moderate than a strategic minimalist who avoids committing to broad principles that might constrain future conservative outcomes.

The Honest Verdict

Kavanaugh’s record in PU domains is the hardest to read of any justice. He breaks from the conservative bloc occasionally (Allen v. Milligan, Murthy v. Missouri, Trump v. Cook) but rarely in ways that produce durable precedent limiting conservative legal movement goals. The Slaughter/Cook pairing — where Kavanaugh endorsed a constitutional rule and then declined to apply it where the consequences would be most severe — is the clearest example of situational constitutionalism in his record: he selectively applies Article II based on institutional risk tolerance rather than textual principle.

OT2025 assessment: This term clarifies Kavanaugh’s pattern. He authored two major conservative victories (NRSC v. FEC dismantling campaign finance limits, West Virginia v. B.P.J. upholding transgender athlete bans) while simultaneously crossing over to protect the Fed in Cook and to invalidate the birthright citizenship order in Barbara (on narrower statutory grounds). His 92% frequency-in-majority rate (OT2024 Stat Pack) — second only to Roberts — reflects his position as the Court’s second pivot point.

The Barbara concurrence is the defining Kavanaugh text of OT2025: reach the anti-administration result, but on the narrowest possible grounds, while explicitly preserving a future pathway for the conservative legal movement to achieve the same policy goal through legislation. This is not independence — it is pragmatic gatekeeping that constrains unilateral executive action while preserving legislative options. That his claimed “roadmap” is constitutionally foreclosed by the very majority opinion he concurred alongside — and by 128 years of precedent, the Amendment’s self-executing text, and its ratification history — does not diminish its political function. The roadmap exists to be cited, regardless of whether it leads anywhere under current law. Its value is aspirational: it signals to a future Court (perhaps differently composed) that at least four current justices would uphold a congressional restriction on birthright citizenship.

The most defensible assessment is that Kavanaugh is a genuine pragmatist and institutional operator — conservative in substantive orientation, aligned with Roberts on institutional preservation, and the Court’s most reliable author of decisions that advance conservative goals through methodologically moderate reasoning. His independence from the Thomas-Alito-Gorsuch pole is structural: he occupies the Roberts lane, not the liberal lane.

Why Trump Supporters Should Care

If you value judicial independence, Kavanaugh voted against Trump’s privilege claim in the January 6 documents case — demonstrating that being appointed by a president does not make a justice that president’s agent.

If you believe in following precedent, Kavanaugh’s Allen v. Milligan concurrence applied existing Gingles precedent faithfully. Whether you agree with the VRA or not, judges who follow the law as written are preferable to judges who change it to reach preferred outcomes.

If you support presidential power, Kavanaugh’s extensive White House experience gives him a sophisticated understanding of executive operations — which informed his vote for presidential immunity. He has direct knowledge of how investigations affect presidential decision-making, making his perspective on immunity more experientially grounded than most justices’.

If you want predictable courts, Kavanaugh’s narrow, fact-specific approach — while frustrating to those who want bold pronouncements — produces decisions that are less likely to generate unintended consequences. Judicial modesty has value regardless of which party benefits.
