Abstract
As a general principle, all relevant evidence in a case should be available for inspection by all concerned parties. However, the public interest may dictate that certain evidence is withheld, and thus frustrate the interests of justice. We need to critically evaluate the mechanisms which exist to ensure that public interest does not compromise the fairness of legal proceedings. In this paper, I am going to answer the research question on State Surveillance and the relevant Hungarian regulations and institutions in this context. As there is no institution in Hungary like the public interest immunity, I present the regulation on covert data gathering and the usage of this information as evidence in the trial.
