 Further, employees of the EPO, no matter whether they are members of the Boards of Appeal, may apply to the Administrative Tribunal of the International Labour Organization (ILO) to resolve employment disputes they may have with the European Patent Organisation.On 3 December 2014, Patrick Corcoran, an Irish member of Board of Appeal 3.5.05, "was escorted out of the [European Patent] Office by [EPO's] investigation unit," and Benoît Battistelli, president of the EPO, imposed a "house ban" on him.In reaction, a number of members of the Enlarged Board of Appeal, the highest body of the EPO judiciary, wrote to the Administrative Council to express their concerns over this move, regarded as challenging the judicial independence of the Boards of Appeal.
