The Prison Service is one of the key organisations needed for the effective and efficient functioning of the state. It has always been associated with the broadly defined prison system. Meanwhile, the powers of the Prison Service go far beyond the prison system and extend to certain aspects of the criminal procedure or public order and safety. Given the above, it is reasonable to ask the question about the status of the Prison Service within the system of public authorities in the state, which includes, among other things, a comprehensive system of legal protection authorities. It may be thus interesting to look at the Prison Service from the point of view of legal protection authorities.
