Fiat Heir John Elkann Loses Swiss Court Bid to Affirm Estate

A Swiss court denied a request by John Elkann, the leader of carmaker Fiat’s founding Agnelli clan, that it assert control over a case in a long-running inheritance dispute that’s pitted the Stellantis NV chairman and his siblings against their mother.

The court in Thun has declared inadmissible requests by John, Lapo and Ginevra Elkann to have a Swiss judge uphold the will of their grandmother, the widow of industrialist Gianni Agnelli. The siblings asked the court to confirm them as heirs and exclude their mother from the estate, lawyers for Elkann’s mother, Margherita Agnelli, said late Tuesday.
