A former soldier has begun his appeal to the Supreme Court against a decision to try him in a Diplock Court.
A Diplock Court is a non-jury trial heard by a judge only. Diplock courts were introduced in 1973 in an attempt to deal with terrorist offences during the Troubles.
The former soldier is due to be tried for attempted murder in connection with a fatal shooting in Northern Ireland in 1974.
The Government technically abolished the old Diplock courts in 2007.
However, the Government gave the Director of Public Prosecutions temporary power to decide that exceptional cases should be tried without a jury if he believed there was still a risk of jurors being intimidated.
