The dispute came to a head in March, when Del Vecchio's Delfin said it would seek arbitration in the International Chamber of Commerce, prompting Essilor to ask a Paris court to nominate an outside mediator. Investors, including Baillie Gifford, Comgest, Edmond de Rothschild Asset Management, Fidelity International, Guardcap, and Phitrust et Sycomore Asset Management, argued that the corporate integration was being undermined by a "major crisis of governance." Their effort to install independent directors on EssilorLuxottica's board failed in a shareholder vote. In May, the two sides agreed to end their legal feud.
