Today, security clearance procedures are used to collect information about persons’ political convictions, social relations and private life, and when this investigation turns out as “negative” persons concerned are denied their rights to serve in public sector, travel, and to benefit from a range of opportunities and services including social assistance and education/training. This means the use of security clearance as a tool by those in the executive to impose upon persons some sanctions that can normally be decided only by the judiciary, and without even notifying or taking the defence of persons concerned. Following the coup attempt of 15 July 2016 in Turkey, important modifications were made in the practice of security clearance during the state of emergency regime (OHAL). When OHAL ended, these modifications were not lifted; to the contrary, the practice which is in contrast with the Constitution and both national and international court decisions has been further deepened. In this context, with a new bill adopted in December 2018, the dominant policy regarding the profession of medicine seeks to reshape the profession by “cleansing” in which security clearance is used as a means.
