If judge enforces law improperly by mistake or by misuse of authority, the rights of the accused person, or parties to the case may be infringed. For centuries, the civil liability of the judge in different legal systems has not been efficiently taken into consideration in spite of the so-called "principle of judicial immunity". By the growth of democracy and with special regard to the principle of equality, the legislators make an effort to take a distance from the principle of absolute immunity, and shift toward civil liability of judge or government.At present, the judge in western countries will confront not only criminal and tribunal liabilities but also civil liabilities when violate the laws. In such a case, a significant portion of losses or damages to the citizens shall be indemnified by the government or insurance companies. In the legal system of Iran, though stipulated in the article 171 of the constitutional law, those parties having sustained a loss or damage due to improper legal decisions are not effectively subjected to the indemnity of the losses incurred. To investigate this issue and its comparison with the legal systems of a number of developed societies in brief is the core discussion of the present paper.
