(one for each branch of the Armed Forces and the other for the National Republican Guard) in each of the following courts: the Supreme Court of Justice, the Relação of Lisbon and the Relação of Oporto. However, in times of war, separate military courts can be re-established. These can be ordinary or extraordinary. The ordinary courts are the Supreme Military Court, the military courts of 2nd instance and the military courts of 1st instance. The military ordinary courts would be composed of the military judges that usually serve in the criminal sections of the common Judicial courts.
