The dead playright, his brother and power of copyright

From the NYT:

"Since Bernard-Marie Koltès died in 1989 at 41, his reputation as a playwright has continued to grow. In February, for the first time, one of his plays, “Le Retour au Désert,” entered the repertory of the Comédie-Française, the historic Paris theater popularly known as the House of Molière.

Yet soon after Muriel Mayette’s production of the play opened there, Mr. Koltès’s brother, François, who owns the copyright to his works, ordered that it be taken off the stage on June 7 after just 30 performances."
