# Know whether the ruling you cite is still the one that counts. *By Alejandro Cárdenas · November 5, 2026 · 9 min read* Citing a ruling that is no longer the one that counts is the mistake that weighs most on a page and shows least while you write it. RuleX sees it for you: when a later decision changed the doctrine, a notice appears under the answer, with the literal sentence from the ruling that changed it. RuleX's case-law graph flags when a ruling cited in the chat or in the Redactor was later modified, unified or abandoned, and shows the literal sentence of the later decision. It also lays the topic out as a line of authority (founding ruling, landmarks, consolidation, shift in doctrine, unification and current ruling) on a base of more than 175,000 decisions from Colombia's Constitutional Court, Supreme Court of Justice and Council of State. ## The ruling you cite may have changed six months ago. Case law is not a monument; it is a river. One chamber departs from the doctrine of another. The Constitutional Court unifies what three chambers had resolved differently. A ruling that was the landmark of one topic becomes the precedent of another. When you draft a cassation appeal (recurso de casación) or a tutela (the constitutional protection action), the ruling you cite with confidence may no longer be the one the judge applies. Checking means opening the decision, searching for the later ones that cite it, reading how they treat it and deciding whether the doctrine still stands. It is hours of work that almost never fits inside the deadline. **RuleX does it in the time the answer takes to appear.** ## Two doors, one notice: the chat and the Redactor. 1. **In the chat: "Validity of what you cite".** Under every answer that cites case law, **only when there is something to say**, a block shows the change: "SL554-2025 departed from the doctrine of SU-005 of 2018", with the literal sentence of the later ruling and, if it is in the base, the legal question it resolved. If nothing changed, nothing is shown. 2. **Also: "Line of authority on this topic".** A collapsed block that opens with one click and lays the topic out: the founding ruling, the landmarks, the consolidation, the shift in doctrine, the unification and the current ruling. It appears when the base covers the topic with enough decisions, so that what you see is a real line. 3. **In the Redactor: the "Validity" panel.** With your draft open, the **"Validity"** button opens the panel "What changed in the rulings you cite". Each notice carries the literal sentence and a button, **"Adjust the citation"**, that sends the Redactor the instruction that corrects the reference. With no citations, there is no panel. 4. **The verb comes from the sentence.** RuleX says "set aside" only when the later ruling says so, and "departed from" when it departs. RuleX never writes "repealed" or "annulled" on its own: the verb comes from the decision itself. > No notice of a shift in doctrine goes out without the literal sentence of the ruling that changed it. > — The rule of the graph ## A working base measured in decisions. - **175,000 +** — decisions from the Constitutional Court, the Supreme Court of Justice and the Council of State in the RuleX working base. - **2,300 +** — rulings with their file card: rules, legal questions and citations, each rule with the verbatim passage it comes from. - **46,000 +** — citation relationships between decisions, the thread that shows who cites whom. - **600 +** — shifts in doctrine identified with the sentence of the later ruling. ## Six roles a ruling plays within a topic. When the base covers a topic, RuleX orders the decisions by the role they play. It is the diagram any lawyer sketches on a sheet of paper, already drawn. - **Founding.** The ruling that raised the problem and set the first criterion. - **Landmark.** The ones that developed or sharpened the rule on a relevant point. - **Consolidation.** The ones that repeated the criterion until it became a stable line. - **Shift in doctrine.** The one that departed, with its sentence and the ruling it left behind. - **Unification.** The one that settled a disagreement between chambers or subsections. - **Current.** The one the court applies today, with the earlier ones around it. ## A labor claim, three citations, one warning. A lawyer prepares the cassation appeal in a pension case and asks the Redactor to build the argument on case law from the Supreme Court's Labor Chamber. - **10:00 a.m. · The Redactor writes.** The draft cites three Supreme Court rulings and one unification ruling of the Constitutional Court, each with its source. - **10:02 a.m. · She opens "Validity".** The panel "What changed in the rulings you cite" shows a notice: one of the decisions she cites was later abandoned by a more recent ruling of the same chamber. - **10:03 a.m. · She reads the sentence.** The notice quotes the paragraph of the later ruling in which the chamber says it departs, and the date. She opens the ruling with one click and confirms. - **10:05 a.m. · "Adjust the citation".** The Redactor rewrites the paragraph: it cites the current ruling as today's criterion and the earlier one as superseded precedent, with the explanation of the change. - **10:08 a.m. · She looks at the line.** She opens "Line of authority on this topic" and sees the whole sequence. She decides to add a paragraph on the founding ruling. **The appeal arrives citing what counts today, with the explanation of why the earlier ruling stopped counting.** ## A notice you check against the text. Each rule on the file cards comes with the **verbatim passage** of the ruling where it appears, checked against the original. Each shift in doctrine reaches the panel only when the later decision itself declares it in the first person. In a sample of thirty-two notices read by hand, every one was a statement of the later decision. It is a read-only query on RuleX's own base: no models at query time, without saving the text you write, with the answer ready before you finish reading yours. **And the source always opens**: the notice takes you to the ruling, not to a RuleX summary. ## Frequently asked questions ### What does the RuleX case-law graph do? It flags when a ruling you cite was later modified, unified or abandoned by a subsequent one, and shows the literal sentence of that decision. It also lays the topic out as a line of authority from the founding ruling to the current one. ### Where does the notice appear? Under the chat answers that cite case law, in a "Validity of what you cite" block, and in the Redactor, in the "Validity" panel, where the "Adjust the citation" button corrects the reference in your draft. ### Which courts does it work with? The Constitutional Court and the Supreme Court of Justice, with a working base of more than 175,000 decisions from those courts and the Council of State, and file cards with rules and legal questions for thousands of rulings. ### How do I know the notice is correct? Each notice carries the literal sentence of the later decision, which opens with one click. Each rule on the file cards carries the verbatim passage of the ruling it comes from, checked against the original text. ### Does it work with tutelas and cassation appeals? It works with any filing or answer that cites case law from the covered courts, whether a tutela, a cassation appeal, a labor claim or a legal opinion. The line of authority appears on the topics the base covers with enough decisions. ### Which country is it for? Colombian case law.
