📄 Fall 2026, Constitutional Law — Memo

The district court's holding in Marbury v. Madison established the foundation for judicial review under Article III.

More recently, in Smith v. Jones, 450 U.S. 462, 468 (2011), the Court addressed the question of personal jurisdiction in the digital age.

What Green Book does

Citation assurance — not a list of features, a clean document.

Click Fix All. Done.

Green Book flags every citation error and shows you the corrected form inline. One click through each suggestion — or one "Fix All" and your citations are submit-ready.

No hunting through the Bluebook. No re-reading rule 4.3(a) for the fourth time.

158 rules. Current edition.

Every rule in the Bluebook 22nd edition — period placement, reporter abbreviations, court designations, pin citations. Deterministic checking, not AI guesswork.

Rules updated when the Bluebook changes. You don't have to re-learn anything.

Works where you write

It's a Google Docs add-on. Open any document, Green Book annotates the citations in place. No upload, no export, no separate tool. Just your doc, with inline corrections.

The only citation tool that runs where 1Ls actually write.

Academic integrity safe

Green Book checks formatting only — not your content, not your argument. Same category as spell-check. Not AI. Not a citation generator. It formats what you wrote.

This isn't a feature most tools have to explain. Ours does, because it matters to law schools.

Your document is citation-clean. Every rule checked, every correction applied, ready to submit.
