Mr Woods' lawyers claim the proper safety procedures were not in place
A police weapons specialist who shot himself in the hand is suing the PSNI.
Peter Woods, 50, was dismantling a gun at a police facility in February last year when the accident happened.
It is understood that he removed the magazine from a pistol, but a bullet in the chamber fired into his hand. He recovered from his injury.
Lawyers for Mr Woods claimed in the High Court that proper safety procedures were not in place, and ammunition may have been faulty.
Mr Woods, a civilian weapons maintenance specialist, was injured at the Seapark base in Carrickfergus, County Antrim, in February 2007.
His legal team is arguing that a proper risk assessment was not carried out and a second person should have been present to reduce the accident risk.
The case was adjourned until next week, when police witnesses are expected to appear before the court.
