Which Trump decisions did Chief Justice Roberts write?

Current as of Aug. 3, 2026. This is a record-style companion for federal-litigation risk tracking, not legal advice. The entries below are limited to Trump-related Supreme Court rulings in which Chief Justice John Roberts personally wrote, announced, or delivered the controlling opinion. Docket numbers, dates, votes, coalitions, holdings, and authorship are tied to the primary opinion record where available.

Scorecard: Trump-related rulings Roberts personally authored

For readers who need the primary documents rather than a table citation, the opinions are here: Trump v. United States, Learning Resources, Inc. v. Trump, Trump v. Slaughter, Trump v. Cook, and Trump v. Barbara.

What the Roberts authorship pattern actually shows

The useful pattern is not that Roberts “sided with Trump” or “checked Trump.” The record is more concrete: when the Court resolved the most visible Trump-related disputes from July 2024 through the close of the 2025-26 term, Roberts repeatedly supplied the controlling legal rule.

That matters because these opinions do different kinds of work. Trump v. United States is an immunity win for a former president, with the operative distinction running through core constitutional powers, other official acts, and the prosecution of conduct outside that protected zone. Learning Resources is an administration loss on tariff authority, and it turns on statutory power under IEEPA rather than a broad judicial posture toward emergency economic policy. Slaughter is a major executive-power win in agency-removal law. Cook limits that same removal impulse where the Federal Reserve is concerned. Barbara is a birthright-citizenship loss for the administration.

The coalition pattern is just as important as the win-loss column. Cook is not a conventional ideological alignment: Roberts writes with Sotomayor, Kagan, Kavanaugh, and Jackson, while Barrett dissents separately from Thomas, Alito, and Gorsuch. Barbara also does not fit a simple ideological lineup: Roberts is joined by Sotomayor, Kagan, Barrett, and Jackson, with Kavanaugh concurring only in the judgment and Thomas, Alito, and Gorsuch dissenting. Those lineups are why the holdings should be lifted by case and coalition, not by assumed bloc.

Slaughter should not be allowed to swallow the whole record. It is the agency-removal case with the largest doctrinal consequence, and it belongs in any Article II removal memo. But the adjacent Cook holding means the same chief justice who wrote the opinion overruling Humphrey’s Executor also wrote the opinion refusing, on the record before the Court, to let the administration carry its removal theory into the Federal Reserve.

The term-level numbers explain why authorship matters

The 2025-26 term statistics put the Trump-related table in context. Roberts wrote six majority opinions and no separate opinions. He and Justice Brett Kavanaugh were each in the majority in 95% of cases, the highest rate on the Court. The same term saw 6-3 decisions rise from 15.2% to 28.8%, ideological 6-3 decisions rise from 9% to 22.7%, and unanimity sit at 44%.[6]

Those figures do not prove that Roberts controlled every outcome. They do make his majority authorship a serious signal for lawyers tracking executive-power disputes. In this slice of the docket, he was not simply joining outcomes; he was drafting the rules that lower courts, agencies, and regulated parties now have to administer.

That distinction is practical. A client alert on tariffs needs the IEEPA holding in Learning Resources, not a paragraph about the Court’s attitude toward Trump. An agency-removal memo needs Slaughter and Cook side by side. A citizenship memo needs Barbara by holding and lineup, especially if it is being paired with statutory proposals such as the site’s H.R. 9854 Citizenship Act explainer.

How to use the record in active litigation

For active litigation tracking, the Roberts-authored decisions are the first layer, not the whole file. Slaughter is the obvious starting point for presidential removal power, but related disputes may ask different questions about office structure, appointment source, statutory tenure, and the remedial posture in which the issue arrives. The site’s Rogoff v. Trump lawsuit record is one place to track that kind of Article II removal-power corollary.

The forward-looking risk notes should stay labeled as forward-looking. A renewed effort to remove Lisa Cook, challenges involving Federal Reserve non-monetary rulemaking, and civil-service removal theories after Slaughter are not resolved by the scorecard above. They are places where the holdings create arguments, carve-outs, or friction points. The controlling texts do not support a clean prediction that every removal claim wins or every Fed-related claim loses.

The same caution applies to emergency-litigation and institutional-conflict coverage. Records such as the Boasberg impeachment risk signal and the Boasberg contempt probe timeline may be useful context for federal-court risk, but they do not change what the Supreme Court held in these Roberts opinions.

Through the 2025-26 term, the verified record supports a mixed, rule-producing pattern. Roberts personally wrote or announced the controlling opinions in the immunity decision, the IEEPA tariff defeat, the FTC removal opinion, the Federal Reserve carve-out, and the birthright-citizenship ruling. That is not a rubber-stamp theory, and it is not a simple anti-Trump correction story. For executive-power, agency-removal, tariff, citizenship, or Federal Reserve litigation risk, the Roberts opinions are the first layer to check; each still has to be read by holding, vote, and coalition.
