Two lawyers can read the same text and defend different conclusions. Does this prove that the law allows people to decide whatever they want? Public debate sometimes skips this essential step: understanding what each person is interpreting, using which method and from which position. An expert opinion, a position taken by the public prosecutor’s office and a court ruling do not play the same role.
In an interview published by France Culture on 30 October 2026, Jean-Paul Jean, honorary presiding judge at the Court of Cassation and a historian of justice, discusses this margin for interpretation. His remarks help frame a question that goes beyond the political cases of the moment: how does an institution reach a decision in law when the answer cannot be found simply by reading a sentence?
Reading a text is not always enough to resolve a dispute
A rule is general; a case is specific. Between the two, it is necessary to determine which facts fall within the scope of the rule and what consequences it entails. This explains why legal professionals who know the same texts can still disagree.
Jean-Paul Jean distinguishes between several approaches. A reading focused on the letter of the text emphasises what it states; a so-called teleological reading looks at the aim being pursued; a consequentialist approach considers the effects of the interpretation adopted. These terms describe ways of reasoning. They do not mean there are three permissions to choose whatever outcome one wants.
This distinction matters to anyone reading about a controversy. Before deciding between two opinions, they can look for the point of disagreement: are the parties discussing the meaning of a word, the scope of a rule or the effects of applying it? Without this clarification, the dispute can seem personal when it may concern a much narrower question.
The Court of Cassation reviews the law, without retrying the case
The Ministry of Justice explains the particular role of the Court of Cassation: it is the highest court in the French judicial system. This clarification matters. It does not mean that it directs every court in the country, particularly those in the administrative system.
Its role is to verify that the rules of law have been applied and the procedures followed, and then to ensure a consistent interpretation of those rules within the judicial system. It does not re-examine the facts of the dispute as if the trial were starting again before it. An appeal to the Court of Cassation is therefore not a fresh opportunity to recount the whole case in the hope of obtaining a different assessment.
If it finds an error that warrants quashing the decision, the Court can set aside all or part of the contested ruling. As a rule, the case is then referred to a court to be heard again. If it dismisses the appeal, the contested decision stands. In either case, understanding the outcome means looking at the legal question that was actually examined.
A headline announcing that a decision has been quashed does not, by itself, mean that all of one party’s claims have been definitively upheld. It is necessary to distinguish between the quashing, its scope and what happens next in the proceedings. This distinction prevents every stage of a court case from being presented as either a total victory or a definitive defeat.
Not everyone who speaks about a case is judging it
The France Culture interview highlights another common confusion. A retired judge may publish a specialist analysis. Their experience gives them the expertise to shed light on the debate, but their text remains a legal opinion: it does not become the Court’s future decision.
The public prosecutor’s office also has a distinct role. Jean-Paul Jean points out that its public positions are not the same as the decision made by the judges responsible for hearing the case. The Ministry distinguishes at the Court of Cassation between councillors and presidents of chambers, who are judges of the bench, and the prosecutor general and advocates general, who represent the public prosecutor’s office.
When following a case, identifying the capacity in which someone is speaking is therefore just as useful as knowing their conclusion. An external analysis may be persuasive, and an argument may be particularly detailed: neither removes the need to wait for the decision of the competent court formation. The prestige of a contributor does not erase this separation of roles.
Disagreement must be explainable
Jean-Paul Jean believes citizens need to understand the justice system’s working methods better. He stresses the importance of decisions with clearer reasoning and the value of research into how courts operate. He also notes the difficulty that the secrecy of deliberations poses for observing them.
That secrecy does not allow commentators to invent intentions behind a ruling. On the contrary, it invites them to work with what is accessible: arguments made public, the rules under consideration and the reasoning set out in the decision. A judgment may have considerable political consequences; that is not enough to establish that its authors were pursuing a partisan aim.
Readers can approach a case by asking three simple questions. Who is speaking: an expert, a party, the public prosecutor’s office or the court? What legal question is being discussed? What does the decision actually change at this stage? This method does not require anyone to agree with the judges. It gives readers firmer ground from which to understand them, discuss their reasoning and distinguish an evidence-based criticism from an accusation based on presumed intentions.
