The author examines the requirements for a public prosecutor's request to the court to obtain data protected by banking secrecy pursuant to Article 106b of the Banking Law. As a result of the analysis, it has been found that there are problems in completing the application in this area, which have not been noticed or have received little attention so far. The main purpose of the paper is to address the identified difficulties and propose solutions. At the same time, an attempt has been made to keep the considerations in close contact with practice.
