José Manuel González-Páramo, a Spanish member of the Executive Board since June 2004, was due to leave the board in early June 2012 and no replacement had been named as of late May 2012. The Spanish had nominated Barcelona-born Antonio Sáinz de Vicuña, an ECB veteran who heads its legal department, as González-Páramo's replacement as early as January 2012 but alternatives from Luxembourg, Finland, and Slovenia were put forward and no decision made by May. After a long political battle, Luxembourg's Yves Mersch, was appointed as González-Páramo's replacement.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did González-Páramo sabotage his seat on the Executive Board?
