Enquiry into moral and sexual harassment: Accusations shake Pierre-Olivier Costa, former chief of staff

Ongoing Investigation: revelations surrounding Pierre-Olivier Costa, former chief of staff, are shaking the cultural milieu. You will learn here that the judicial procedure is now targeting facts of moral harassment, sexual harassment, and suspicions of favoritism.

In brief — A preliminary investigation opened in Marseille in March has been supplemented by a report from the General Inspectorate of Cultural Affairs; the president of MuCEM was suspended at the end of June and the justice system is examining ethical violations and management issues raised in this document.

Expanded Judicial Investigation Targeting Pierre-Olivier Costa

The justice system in Marseille opened a judicial procedure in March, following the transmission of a report from the IGAC pointing out dysfunctions at MuCEM. According to Le Monde, the dossier has been enriched and the investigations have expanded to the internal practices of the institution. You will see that the accumulation of testimonies has changed the tone of the case.

Accusations of Sexual and Moral Harassment at MuCEM

The IGAC report recounts very serious testimonies from former collaborators. An ex-executive claims repeated injunctions, up to thirty times the phrase “come suck me,” and others report remarks about their intimate parts. These allegations fuel lawsuits for sexual harassment and moral harassment, while La Provence details the testimonies and the atmosphere described internally.

Suspicions of Favoritism and Criticized Management

The IGAC document is not limited to individual behaviors: it points out questionable internal procedures and decisions made under opaque conditions. Investigators are now looking into possible cases of favoritism related to appointments and contracts. The report also discusses Costa’s past connections with the Élysée, which revives the debate on the impartiality of cultural appointments; to understand the context of the Élysée-MuCEM relationships, refer to a contextual file on ties with Brigitte Macron.

Suspensions and Judicial Perspectives

Conservatory suspension announced on June 30/early July, recommendation for revocation by the IGAC: Pierre-Olivier Costa contests the accusations while the justice system prolongs its investigations. The inquiries now cover harassment, museum management, and possible ethical violations. For an overview of the facts and institutional reactions, a recent article from the specialized press reviews the status of the procedure.
