Operation Sledgehammer
In 2012 he was sentenced to twenty years in prison for his alleged involvement in the 2003 "Sledgehammer" coup plan;[7] Doğan is said to have been the leader of the group that planned the coup.[8][9] He was later acquitted in 2015.[10] He is also charged in the case of the 1997 military memorandum.[11]
Professor Dani Rodrik (Doğan's son-in-law) has written that the Sledgehammer evidence against Doğan was fabricated, citing various anachronisms and errors in the key coup plan document.[12][13]
