In the scientific article, the author investigated the concept of knowledgeable persons in the criminal justice system of Ukraine.
In particular, it was determined that the term "informed persons" appeared for the first time in the 19th century and was enshrined in the Code of Criminal Laws of the Russian Empire in 1832 and the Statute of Criminal Procedure in 1864.
