Quick answer
The review application under Article 954.1.c) of the Spanish Criminal Procedure Act (LECrim) is the remedy for correcting a double conviction for the same facts once no ordinary appeal remains. STS 1040/2025, of 17 December, admits the review, declares the constitutional prohibition of ne bis in idem breached, and partly annuls the second judgment. The consequence is that the first conviction prevails and the second, in so far as it covers the same facts, is rendered void. The ruling confirms that the injury to the value of justice inherent in a double conviction opens the review route even without a later contradictory judgment.
STS 1040/2025, of 17 December 2025 (appeal 21646/2024), addresses one of the gravest forms of double jeopardy: a repeated conviction for the same facts already tried. The Criminal Division of the Supreme Court partly annuls the second judgment on finding a direct breach of the constitutional prohibition of ne bis in idem, doing so through the extraordinary review application under Article 954.1.c) of the Criminal Procedure Act (LECrim).
The review requirement: double conviction for the same facts
The review application under Article 954 of the LECrim is an extraordinary remedy against final judgments. Its function is not to correct errors of legal classification or to re-assess evidence: it is to repair situations of substantive injustice that emerge after a judgment becomes final and can no longer be challenged through the ordinary routes. Double convictions fall squarely within those situations.
In the case resolved by STS 1040/2025, the accused had been the subject of two separate criminal proceedings that converged, in a material part, on the same facts. The second judgment convicted him, among other matters, of breaching a precautionary measure under Article 468.2 of the Criminal Code. The problem was that those same facts had already been the subject of a prior final conviction.
The constitutional basis: the prohibition of ne bis in idem
The Supreme Court recalls that the prohibition of ne bis in idem has a twofold content. In its substantive dimension it prevents the same conduct from being punished twice. In its procedural dimension it bars the same facts from being tried in two separate proceedings. Both dimensions form part of the right to effective judicial protection under Article 24 of the Spanish Constitution and of the superior value of justice proclaimed in its Article 1.
The Chamber stresses that the injury to the value of justice caused by a double conviction is, in itself, a sufficient ground to open the review under Article 954.1.c) of the LECrim. No later contradictory judgment is needed, nor must any other new fact be present beyond the duplication itself: the fact that the acts in the second case are the same as those already sanctioned in the first is enough to trigger the review remedy.
The consequence: first judgment prevails, second is void
Once the double conviction is established, the Supreme Court sets out the legal consequence with clarity. The first final judgment prevails in full. The second judgment is partly annulled in everything that punishes the same facts already tried: in the concrete case, the conviction under Article 468.2 of the Criminal Code is set aside.
This solution respects the preclusion inherent in res judicata: the first conviction — which was also final — cannot be challenged by this route. Only the ruling that infringes ne bis in idem is annulled, that is, the one that fell upon previously sentenced facts. The practical result is that the convicted person remains subject only to the first penalty with respect to those facts.
Articles involved: 468.2 and 550 of the Criminal Code
The facts of the case centred on Articles 468.2 and 550 of the Criminal Code. Article 468.2 punishes breach of precautionary measures in the context of domestic or gender-based violence; Article 550 governs assaults on authority. The overlap between the two judgments concerned the Article 468.2 offence, which was the core of the successful review application.
The ruling does not modify the substantive interpretation of either provision. Its contribution is strictly procedural: it shows that where a second conviction for breach of a precautionary measure — or for any other offence — covers conduct already sanctioned in a prior case, Article 954.1.c) of the LECrim is the appropriate instrument for remedying it.
Practical relevance for the defence
STS 1040/2025 is of direct interest to any defence that, on examining its client's background, identifies that a final judgment convicts for facts already tried in a prior case. This scenario is not uncommon: it arises when the same conduct gives rise to parallel proceedings, or when procedural consolidation fails and the facts are spread across different cases.
In those situations, the ruling confirms that the review application under Article 954.1.c) of the LECrim is an effective route, and that a successful outcome leads to the annulment of the second conviction, with the consequences that flow from this for the penalty already served. Identifying the double conviction, establishing the identity of the facts, and building the review application are the three central tasks in this type of case.
Frequently asked questions
When does a review application lie on ne bis in idem grounds?expand_more
It lies when, after a conviction becomes final, it is established that the convicted person was tried and convicted twice for the same facts. Article 954.1.c) of the LECrim allows review wherever the duplication of convictions injures the value of justice. No later contradictory judgment is required: it suffices to show that the facts tried in the second case are the same as those already covered by the first conviction. The Supreme Court annuls the second judgment to the extent it overlaps with the first.
What is the difference between a review application and a cassation appeal?expand_more
A cassation appeal challenges a judgment before it becomes final, on grounds of a violation of law or procedural rules. A review application is extraordinary and lies only against final judgments: it operates when, after finality, facts or circumstances come to light that show the injustice of the conviction, such as the existence of a prior judgment on the same facts. Both routes go to the Supreme Court but have entirely different requirements, time limits and grounds.
What happens to a sentence already served if the review succeeds?expand_more
If the Supreme Court allows the review and annuls the second conviction, the time spent in custody or serving the penalty derived solely from that second judgment must be taken into account in the final calculation. The first judgment remains final and cannot be challenged through this route. In practice, a successful review can affect the total sentence calculation, sentence consolidation, and the entries on the criminal record.
Who may bring a review application?expand_more
The convicted person (and, after their death, their spouse, ascendants, descendants or siblings) and the public prosecutor (Ministerio Fiscal). The application is filed directly before the Criminal Division of the Supreme Court. It is not subject to any limitation period or specific lapse period, although prompt action is advisable to avoid prejudice from the continued enforcement of a sentence that should be annulled.
