A justice ministry, ministry of justice, or department of justice, is a ministry or other government agency in charge of the administration of justice. The ministry or department is often headed by a minister of justice (minister for justice in a very few countries) or a secretary of justice. In some countries, the head of the department may be called the attorney general, for example in the United States.
Depending on the country, specific duties may relate to organizing the justice system, overseeing the public prosecutor and national investigative agencies (e.g. the American Federal Bureau of Investigation), and maintaining the legal system and public order. Some ministries have additional responsibilities in related policy areas such as overseeing elections, directing the police, law reform, and administration of the immigration and citizenship services. Some nations separate the duties of the ministry of justice from responsibility for the prosecution of criminal cases, such that the duties of an attorney general or similar officer reside in a separate office. Sometimes the prison system is separated into another government department called Corrective Services.
