Yves Bouvier pushes to have New York art consultant’s dealings revealed in US court

The New York-based art consultant Sandy Heller has disclosed he was employed by Dmitry Rybolovlev, the Russian billionaire and owner of AS Monaco football club, as an art adviser in February 2015. Heller’s position was revealed in an affidavit he submitted to a US federal court in December following a petition filed by the Swiss freeport magnate, Yves Bouvier, to have Heller questioned about his dealings with the Russian collector. Bouvier is now pushing to have further documents connected to the sale of a painting by Modigliani disclosed.
