When opening a ruling from the Court of Cassation to prepare a commentary, the first difficulty is not understanding the solution: it is measuring its scope. One reads a well-crafted statement, identifies a formulation that seems to establish a rule, and the temptation is strong to qualify the decision as a ruling of principle. The problem is that this overqualification skews all subsequent analysis of scope.
Understanding the difference between a ruling on a specific case and a ruling of principle relies less on theoretical definitions than on a methodical reading of the reasoning. Before classifying a ruling, one must check whether the Court formulates a rule that can be detached from the facts or if it merely applies a text to a given situation.

Overqualifying a ruling as a ruling of principle: the most common trap in commentary
In seminars, we often observe the same reflex: the student spots a headnote or a citation and concludes that it is a ruling of principle. This is a misleading shortcut. A citation is not enough to make a decision a ruling of principle. The citation recalls the applicable rule of law, but the question is what the Court makes of it.
To avoid this mistake, one can apply a simple test: could the reasoning of the ruling apply word for word to another dispute, with different facts? If so, one is probably facing a general rule. If the solution only holds in the presence of the specific circumstances of the case, one remains within the ruling on a specific case.

Let’s take a concrete example. A decision stating “whereas the professional seller is required to deliver a conforming product” establishes a rule applicable to any professional sale. In contrast, a decision stating “whereas in this case, the defect concerned the color of the ordered coating” remains anchored in the facts. The phrase “in this case” almost always signals a factual reasoning, thus a ruling on a specific case.
Reasoning of the ruling: read the reasoning before qualifying the scope
The key to the distinction lies in the structure of the reasoning, not in peripheral information (formation, publication). One begins by identifying whether the Court states an autonomous principle or if it controls the application of the law to the facts by the lower court judges.
The detachable general rule
In a ruling of principle, the Court of Cassation formulates a legal proposition that transcends the dispute. This formulation often takes the form of a principle statement (or, since the drafting reform, a numbered paragraph stating the rule). The rule must be able to be cited in isolation, without reference to the facts.
This structure is recognized by several textual indicators:
- The Court uses general terms (“any person”, “the creditor”, “the lessor”) without referring to the named parties of the dispute.
- The legal proposition precedes the examination of the facts, indicating that it is posed as a premise and not as a conclusion drawn from the circumstances.
- The formulation is reproduced identically in subsequent decisions, a sign that the Court conceived it as a reference norm.
The disciplinary control of the facts
Conversely, when the Court merely checks that the lower court judges correctly applied an existing rule to the facts, one is faced with a ruling on a specific case. The reasoning then multiplies references to factual elements: dates, amounts, behaviors of the parties. The ruling on a specific case does not create law; it controls its application.
This type of decision is of little interest to doctrine because its scope does not exceed the case file. It will be referred to as a technical or disciplinary control, depending on the circumstances.
Complementary indicators: formation, publication, and doctrine
The reasoning remains the decisive criterion, but other elements can support or refute the analysis. None of these indicators is sufficient on its own.
- The formation of judgment: a ruling issued in a plenary assembly or in a mixed chamber of the Court of Cassation is more likely to be a ruling of principle, because these formations are mobilized to resolve new questions or divergences between chambers.
- Publication in the Bulletin: a ruling published in the Bulletin of the Court of Cassation indicates that the jurisdiction considers the decision significant. Rulings on specific cases are generally not published.
- Reception by doctrine: if authors comment extensively on the decision and extract a rule from it, this is a strong indicator. However, doctrine can also overinterpret a ruling on a specific case.
- The type of decision: a ruling of cassation is more often of principle than a ruling of rejection, because cassation implies stating the rule that the lower court judges should have applied.
Feedback varies on this point, as some rulings of rejection also establish principles, particularly when the Court explicitly approves the reasoning of the court of appeal by stating a general rule.
Concrete method for qualifying a ruling in a commentary
When writing a ruling commentary, the qualification occurs in the assessment of the scope, generally at the end of the development. Here is the approach one can follow to avoid mistakes.
First, isolate the passage of the reasoning that contains the solution. Reread it while mentally removing any reference to the facts. If the sentence retains a complete legal meaning, one has a general rule, thus an indicator of a ruling of principle. If it becomes incomprehensible without the facts, the decision remains tied to the dispute.
Next, check the formation and publication. These elements confirm or nuance the hypothesis but never establish it alone. A ruling issued by a simple chamber and not published in the Bulletin can hardly be presented as a ruling of principle, even if its reasoning seems to establish a rule.
Finally, check whether the formulation has been reproduced in subsequent decisions. When the Court of Cassation reproduces a statement word for word in several successive rulings, the qualification of a ruling of principle becomes solid. The repetition of a formulation by the jurisprudence confirms its general scope.
Qualifying a ruling is not a binary exercise. Some decisions fall into an intermediate zone, where the Court seems to establish a rule while remaining very tied to the facts. In these cases, it is better to signal the ambiguity in the commentary rather than artificially decide. A reviewer will always prefer a nuanced analysis to a label applied without justification.
