Magnanville case: what the third trial of Mohamed Lamine Aberouz really changes

This update focuses on Magnanville case. France’s Court of Cassation has ordered a third trial for Franco-Moroccan Mohamed Lamine Aberouz, without overturning his final life sentence for the double police killing in Magnanville.

A third trial, but guilt already established

The ruling, delivered on Wednesday 23 September, does not restart the Magnanville case from scratch. The Court of Cassation annulled only part of the appeal judgment that sentenced Aberouz on 25 June 2025 to life imprisonment with a 22-year minimum term.

The annulment concerns his alleged complicity in the kidnapping of the couple’s three-year-old son during the attack. The high court identified a discrepancy between the questions put to the jury and the written reasoning of the appeal decision.

By contrast, the convictions of Mohamed Lamine Aberouz for complicity in the murders of the couple and for terrorist conspiracy remain final. The future court will therefore not be allowed to revisit his responsibility for the double killing.

Life sentence in the Magnanville case remains in force

In practical terms, the life sentence with a 22-year security period remains fully in force. The new assize court will only rule on the annulled part linked to the child’s sequestration and adjust the overall sentence accordingly, without reducing the portion already confirmed for the murders.

Aberouz had already received the same sentence at his first trial in October 2023, then again on appeal in June 2025. Prosecutors relied in particular on a DNA trace found on the wrist rest of the victims’ computer to establish that he had been inside the family home.

On 13 June 2016, jihadist Larossi Abballa murdered police commander Jean-Baptiste Salvaing and his partner Jessica Schneider at their home in Magnanville, near Paris, before claiming allegiance to the so‑called Islamic State group.

Impact for Moroccans living in France and Europe

For Moroccans living in France or with close family there, the Magnanville case is a reminder of how French courts handle terrorism cases involving dual nationals or people of foreign origin.

This third trial does not affect the migration status of Mohamed Lamine Aberouz, nor the residence rights of other Franco-Moroccans. It has no direct impact on entry and exit rules for Moroccans abroad.

However, it highlights several points that matter for Moroccans living in Europe, especially in France:

• terrorism cases can drag on for many years through several levels of jurisdiction;
• the Court of Cassation may correct procedural flaws without reopening the entire conviction;
• final terrorism convictions are extremely difficult to challenge on the merits.

For those planning to return to Morocco or travel frequently between the two countries, the this case does not alter the usual border checks or standard administrative procedures. It belongs primarily to the internal working of the French justice system.

A sensitive security context for the Moroccan community

The Magnanville murders remain one of the most symbolic cases from the wave of terrorist attacks that hit France in the 2010s. For the Moroccan community in France, such trials can reignite fears of stigmatization or confusion between terrorism and national origin.

French authorities insist that each case is handled individually, based on evidence and legal criteria, as illustrated by the path followed by Mohamed Lamine Aberouz before the Court of Cassation.

Meanwhile, Moroccans abroad continue to enjoy the same rights and obligations as other residents, whether or not they hold dual nationality. For their everyday procedures with Morocco – passports, civil status, return projects – families can rely on consular services and official Moroccan platforms such as the dedicated portal for Moroccans living abroad, which operates independently of this highly specific criminal case.

Nearly ten years after the events, the new twist in the this issue mainly shows that French courts are still fine-tuning the legal form of their decisions, while firmly maintaining the sanctions imposed for the most serious crimes.
