A principle ruling establishes a general legal rule intended to apply beyond the resolved dispute. A case ruling addresses a specific case without formulating a reproducible norm. The challenge for a law student or practitioner lies in identifying within the text of the decision the clues that shift it from one category to another.
What the 2019 reform changed in reading rulings
Before October 2019, the Court of Cassation drafted its decisions in “recitals,” a single and often elliptical sentence. Distinguishing a principle ruling from a case ruling then meant searching for a “principle recital” formulated in general and abstract terms, detached from the facts.

Since the reform of the drafting that came into effect on October 1, 2019, the Court has abandoned the indirect style of recitals in favor of a richly structured motivation, organized in numbered paragraphs. The reasoning is more explicit, and the scope of the solution is often clarified within the motivation itself.
This evolution creates a trap: a ruling can be extensively motivated without necessarily establishing a general principle. The Court has also introduced “specially motivated decisions,” which elaborate on reasoning in complex cases without necessarily establishing a new rule. Therefore, it is essential to distinguish between case rulings and principle rulings by separating the quality of the motivation from the normative scope of the solution.

In practice, the reform requires a more nuanced reading. A paragraph that states a rule in abstract terms, without reference to the facts of the case, indicates a principle ruling. A development that, even if lengthy, remains anchored in the circumstances of the dispute points towards a case ruling.

Concrete criteria for identifying a principle ruling in law
No single criterion is sufficient on its own. It is a convergence of clues that allows for the qualification of the decision. Three families of signals deserve particular attention.
The formation and jurisdiction
A ruling made by the Plenary Assembly or the mixed chamber of the Court of Cassation has a high probability of being a principle ruling. These formations are seized when a legal question divides the chambers or presents particular importance. Conversely, a ruling made by a single chamber, in a restricted formation, leans more towards a case ruling, even if the rule is not absolute.
On the administrative side, the rulings of the Council of State in Section or Assembly play a comparable role.
The structure of the decision
Since the reform, the most reliable signal remains the presence of a “header” (or visa) followed by a principle statement formulated in an abstract manner. When the Court writes “it follows from this text that…” and then states a rule detached from the facts, the general scope is indicated. When the motivation remains anchored in the factual circumstances (“in this case,” “considering the elements submitted”), the decision is limited to the specific case.
The dissemination and doctrine
- Publication in the Bulletin is a strong indicator: the Court of Cassation selects decisions it deems to carry a new rule or notable confirmation. A ruling not published in the Bulletin is rarely a principle ruling.
- The mention on public databases (Judilibre, Légifrance) with a summary drafted by the Court’s documentation service also signals the importance attributed to the decision.
- Comments from doctrine (case notes, articles in legal journals) confirm a posteriori the principle scope. A ruling that does not elicit any doctrinal reaction remains, except in rare cases, a case ruling.
Case ruling: why it should not be underestimated
Law students tend to view the case ruling as an uninteresting decision. This reading is too quick. A case ruling illustrates the concrete application of a legal rule to specific facts. In a case comment, identifying a decision as a case ruling is already a legal analysis, not an admission of powerlessness.
The case ruling is recognized by reasoning that does not exceed the factual framework submitted to the judge. The Court of Cassation exercises a control described as “disciplinary” or “light normative”: it verifies that the lower judges have correctly applied the existing rule, without altering its scope.
Moreover, the boundary is not always clear. Some rulings initially considered as case rulings have been reclassified by doctrine as principle rulings after their solution was adopted by other jurisdictions. The qualification can evolve over time, which relativizes any fixed classification.

Quick reading grid for a case comment
During a university exercise, the approach can be summarized in a series of successive checks.
- Which jurisdiction issued the decision, and in what formation? Plenary Assembly, mixed chamber, or single chamber guide the response.
- Does the decision contain a statement formulated in abstract terms, detached from the facts of the dispute? If so, a general principle emerges.
- Is the ruling published in the Bulletin or referenced with a summary on public databases? The dissemination chosen by the Court reflects the scope it intends to give to its decision.
- Has the doctrine commented on the decision? The absence of commentary, combined with other indicators, confirms the case nature.
None of these criteria is sufficient on its own. It is their convergence that establishes the qualification. A ruling published in the Bulletin, issued by the Plenary Assembly, with a visa and an abstract statement, ticks all the boxes for a principle ruling. A chamber ruling, unpublished, with factual motivation, falls under the case ruling.
The 2019 reform has made this reading grid both more accessible (the motivation is clearer) and more demanding (the length of the motivation no longer guarantees the scope). Taking the time to separate factual reasoning from normative statements remains the most reliable method for correctly qualifying a decision.
