Legal provisions have to be sufficiently clear and detailed to give you an adequate indication as to the circumstances and the conditions under which public authorities can interfere with your right to private life, in the course of investigative and operational actions. In addition, an effective mechanism for how to complain about a potential abuse or misuse of your data has to be stipulated in law.
If you believe that the relevant legal provisions in the Criminal Procedure Law and in the Investigatory Operations Law are not sufficiently clear and precise, or do not guarantee effective safeguards against potential abuses and misuses, and thus your right to private life has been violated, you can submit an application to the Constitutional Court of the Republic of Latvia. You can read more about the Constitutional Court and about how to prepare your application in the Law on the Constitutional Court of the Republic of Latvia.
