The two Roberts courts

The United States Supreme Court, often characterized by a 6-3 conservative supermajority, frequently presents two distinct judicial landscapes, a phenomenon dubbed the “two Roberts courts.” While many high-profile decisions align with a predictable ideological split, a significant pattern of internal disagreement within the conservative bloc also emerges in close cases. This internal fracturing, driven by differing interpretive methodologies and institutional concerns, can lead to unexpected coalitions where conservative justices join their liberal colleagues. This dynamic necessitates a nuanced understanding for legal practitioners, as the Court's outcomes are not solely dictated by the numerical ideological advantage but also by the intricate interplay of judicial philosophies and strategic considerations among the justices.

The United States Supreme Court's current composition, with six justices appointed by Republican presidents and three by Democratic presidents, often leads to a shorthand understanding of its decisions as a straightforward 6-3 ideological split. This perception, while accurate for many high-salience constitutional and regulatory cases, overlooks a more complex reality. Beneath the surface of this numerical advantage lies a nuanced internal dynamic, revealing what some observers have termed the “two Roberts courts.”

This dual nature of the Court signifies that while one version operates along predictable conservative-liberal lines, another frequently emerges where the conservative majority itself is fractured. These internal divisions, often rooted in differing approaches to legal interpretation or institutional concerns, can lead to unexpected coalitions and outcomes. For legal practitioners, understanding this intricate interplay of judicial philosophies and strategic alignments is crucial for accurately forecasting judicial trends and advising clients, as the Court's decisions are not always a foregone conclusion based solely on its ideological makeup.

This article explores the phenomenon of the “two Roberts courts,” examining how the Court's internal dynamics, particularly within its conservative wing, shape its jurisprudence. By analyzing recent cases, it highlights the factors that contribute to these splits and offers insights into their implications for the legal landscape.

The Supreme Court's current 6-3 conservative majority was solidified with the appointment of Justice Amy Coney Barrett in 2020, shifting the Court's ideological balance significantly to the right. This composition has indeed led to a series of landmark decisions reflecting a conservative judicial philosophy, particularly in areas such as abortion rights, gun control, and administrative law, where the six conservative justices have often formed a unified front against the three liberal justices. Cases like *Dobbs v. Jackson Women's Health Organization* (2022) and *New York State Rifle & Pistol Association Inc. v. Bruen* (2022) exemplify this familiar ideological alignment.

However, the Court's history demonstrates that ideological labels do not always fully capture the complexities of judicial decision-making. Justices, even those sharing a broad ideological outlook, may diverge on specific legal methodologies, the application of precedent, or the institutional role of the Court. This inherent tension within any ideologically aligned bloc can lead to unexpected outcomes, challenging the simplistic notion of a monolithic majority and revealing the deeper doctrinal and jurisprudential debates that shape the Court's work.

The concept of the “two Roberts courts” highlights that a 6-3 decision can either reflect a standard ideological divide or, critically, expose significant disagreement within the conservative majority itself. The first type of 6-3 decision, as illustrated conceptually by the prompt's reference to *Louisiana v. Callais* (October Term 2025), might see Chief Justice Roberts and Justices Thomas, Alito, Gorsuch, Kavanaugh, and Barrett forming a majority, with Justices Kagan, Sotomayor, and Jackson dissenting along predictable ideological lines.

However, the second type of 6-3 decision reveals a fractured conservative Court, where the liberal justices become pivotal due to internal disagreements among their conservative colleagues. A prime example from the October Term 2025-2026 is *Learning Resources, Inc. v. Trump* (2026), where the Court struck down President Trump's “Liberation Day” tariffs. Chief Justice Roberts authored the majority opinion, joined by Justices Gorsuch and Barrett, and notably, all three liberal justices. Justices Thomas, Alito, and Kavanaugh dissented, demonstrating a clear split within the conservative bloc on a significant issue of presidential power. This case underscores how different interpretive approaches, such as textualism (often favored by Gorsuch and Barrett) versus other forms of originalism or broader executive power views (sometimes favored by Thomas and Alito), can lead to divergent outcomes even among conservative justices.

Chief Justice Roberts often plays a crucial role in these internal splits, sometimes siding with the liberal wing to form a majority. His decisions in cases like *June Medical Services v. Russo* (2020), where he joined the liberal justices to strike down a Louisiana abortion law based on stare decisis, despite his prior dissent in a similar Texas case, exemplify his institutionalist approach. Similarly, in *Allen v. Milligan* (2023), Roberts and Justice Kavanaugh joined the liberal justices to uphold Section 2 of the Voting Rights Act, striking down an Alabama redistricting plan, a decision that surprised many and went against conventional wisdom about the conservative bloc's unity on individual rights cases. These instances highlight Roberts's perceived role as an incrementalist and an institutionalist, seeking to maintain the Court's credibility and stability, which can lead him to forge cross-ideological coalitions.

Furthermore, even in cases with unanimous outcomes, conservative justices may differ significantly in their reasoning, reflecting ongoing debates about legal methodology. For example, in some unanimous rulings, conservative justices have offered separate opinions that reveal distinct approaches to textualism or originalism, indicating that consensus on the outcome does not always equate to consensus on the legal path taken. This internal friction, driven by varying judicial philosophies, means that practitioners must delve beyond the simple vote count to understand the underlying legal reasoning and potential future implications.

The phenomenon of the “two Roberts courts” profoundly impacts legal practice, demanding that attorneys move beyond a superficial understanding of the Supreme Court's ideological composition. Practitioners must meticulously analyze not only the broad ideological leanings of the justices but also the nuanced interpretive methodologies and institutional concerns that can fracture the conservative majority. This requires a keen awareness of individual justices' jurisprudential tendencies, such as Justice Gorsuch's textualism, Justice Alito's more traditional originalism, and Chief Justice Roberts's emphasis on stare decisis and institutional legitimacy.

Going forward, practitioners should closely monitor concurring and dissenting opinions, even in seemingly straightforward 6-3 decisions, as these often reveal the fault lines within the conservative bloc that could become decisive in future cases. The ability to anticipate when a conservative justice might align with the liberal wing, or when different conservative factions might emerge, will be critical for effective legal strategy and advocacy. The Roberts Court, therefore, presents a dynamic and complex judicial landscape where outcomes are shaped not just by numbers, but by the intricate dance of legal philosophy and judicial statesmanship.
