National Criminal Register (Poland)
National Criminal Register (Polish: Krajowy Rejestr Karny) is the official database of criminal convictions and other law enforcement data kept by Poland’s Ministry of Justice. It was created on 22 June 2001 by the Act of 24 May 2000 and replaced the old Central Register of Convicts and Central Register of Juvenile Offenders.
In early 2022 the Ministry announced plans to reform the Register. The ideas include sharing some official notices and documents digitally between authorities and linking the Register with the PESEL Register. The reform aims to create a new computer system called KRK 2.0.
What is stored: The Register holds data about convictions and other penalties, but it does not include fixed penalties like most traffic fines unless a custodial sentence was imposed. The Register is not public. Access is limited to authorities (such as police, prosecutors, courts, intelligence and security agencies, border guards, anti-corruption bodies, and military intelligence), the data subject, and, in limited cases, the data subject’s employer when required by law.
Usage and deletion: In 2019, data in the Register were accessed about 3 million times a year, with about 80% of access by state authorities. Convictions are automatically removed when they become “spent” under Polish law. Conditional discharges are removed if no further offence occurs within the probation period or if proceedings resume after a breach. Preventive measures are removed when they expire. Data are also removed when the person dies.
