Art. 23 1/15 (also referred to as G 2301/15), Art. 23 2/15 (also referred to as G 2302/15) and Art. 23 1/16 are three related cases decided by the Enlarged Board of Appeal of the European Patent Office concerning the removal from office of a member of the Boards of Appeal, who had been previously suspended by the Administrative Council of the European Patent Organisation.
 According to Article 23(1) EPC , members of the Boards of Appeal may only be removed from office by the Administrative Council on a proposal from the Enlarged Board of Appeal.
 Two cases were successively initiated by the Administrative Council, but the Enlarged Board eventually dismissed both of them.
 In the third case initiated by the Administrative Council, the Enlarged Board decided not to propose the removal from office of the member of the Boards of Appeal.
