Balancing the rights of physicians and patients, due to Medicine's age and importance, has always been a challenge for jurists. On the other hand, Ehsan doctrine has been studied and implemented by Islamic and Iranian scholars for decades. Although it is obvious that medical practices are Altruistic, it is troubling to consider the providers of medical services Alturists, based on our countrie's laws and jurisdiction procedures. Therefore, even though the relation between medical responsibility and Ehsan doctrine has been vastly studied, a new look at this topic by comparing it against its counterpart in common-law, Good Samaritan law, can be promising in determining physician's liabilities. This thesis presents a clear comparison and conformation of physician's liabilities based on Ehsan doctrine in Islamic law and the Good Samaritan law in common-law through literature review. The findings of this research demonstrate that the Good Samaritan law only applies to out of contract liabilities and commonly to non-physicians in emergency situations while the Ehsan doctrine has a broader application and, assuming the perquisites are provided, can include all physician's liabilities. Moreover, the confirmative aspect of Ehsan doctrine in providing grounds for charging fees is an advantage over the Good Samaritan law.
