Who is eligible for immunity under Tort Law?

Under Tort Law, certain kind of “immunity” is granted to judicial officers and quasi-judicial authority. It is important here to know the basic difference between the said authorities to make the whole idea of immunity clearer. Judicial authorities are that of court of law or judges which interpret the law, settle disputes and punish those who broke the code. On the other hand, quasi-judicial bodies are authorities who have powers resembling those of the judicial bodies and are restricted to certain areas of expertise. Judicial authorities may have the power to create new laws in time of dire need leading to Judicial Activism, however, quasi-judicial bodies do not have this power and are bound to draw conclusions based on existing law.  The defence of “immunity” under tort law is required so that it does not intervene with their process of work.
