At that time , he took up the most important case : the Yak-42 accident in Turkey , which killed 62 soldiers on their return from Afghanistan on 26 May 2003 . However , four months after arriving at the courthouse , on 1 June 2007 , he filed the case and attributed the responsibility to the Ukrainian crew , absolving the Ministry of Defense of the accident for hiring an unsafe plane . However , on 22 January 2008 , the Fourth Section of the Criminal Division unanimously revoked the file , alleging that the judge had not exercised any diligence or defencelessness on the part of the victims . Once the case was reopened , he called as witnesses the military leadership of the time , and former ministers Federico Trillo and José Bono . Finally , on 20 May 2008 , he charged five high-ranking military commanders , including the Chief of the Defence Staff , Antonio Moreno , the highest military officer at the time of the accident , with 62 counts of serious negligence
