Res judicata as a concept under administrative law

Administrative Law deals with the structure, functions, and powers of the organs of administration. Administrative Law is also known as regulatory law and it is enforced by some type of government body. The law derives its power to enforce regulation from the government body. This applies to all public officials and agencies. An administrative body of government may rulemaking or enforce a specific agenda. It is technically considered as a branch of public law. The administrative authority is different from the legislative and judicial authority and necessitates the power to issue rules and regulations that are based on grant licenses and permits. The basic principles of this law are that no person shall be unheard or deprived of his right and a person cannot be a judge on his own in a case. 

Res judicata works as a working principle under administrative law and has been adopted from the Civil Procedure Code.
