Abstract
The medical profession is historically regarded as sacred in the society. The considerable expansions of medicine in various areas with the aim of fully diagnose and treat people’s illnesses have created certain circumstances in such a way that besides positive impacts, some medical practices negatively affect patients’ mental and physical health. Thus, it is necessary that the physician be responsible for damages he or she makes to patients’ mental and physical status. This research, which is done using analytical-descriptive methodology and collecting library resources, seeks to find answers to the question that: does a physician have criminal liability as well as civil liability in the legal system of Iran. The obtained results show that the lawmaker has acknowledged the criminal liability of the physician if it meets the requirements of the law.
