A judge has given the go-ahead for a fresh inquest into the death of Private Sean Benton which took place at Deepcut barracks 21 years ago.
Private Benton, from Hastings, was found with five bullet wounds to his chest in June 1995 while undergoing training at the Surrey base.
The 20-year-old's twin brother Tony and sister Tracy Lewis attended court today to apply for the new hearing.
The application was made possible by their mother Linda who, before her death last year, used the Human Rights Act to access evidence held by Surrey Police.
The original inquest recorded a verdict of suicide, and a criminal investigation seven years later found no evidence that anyone else was involved.
Private Benton's family believe he was subjected to severe bullying.
He was the first of four young soldiers to die at the barracks between 1995 and 2002.
In June the head of the Army said that a public inquiry into Deepcut barracks should be held if it is the "best method" of getting the truth.
General Sir Nick Carter also apologised "unreservedly" to the parents of Private Cheryl James after an inquest which found she killed herself also criticised the care offered to recruits at Deepcut barracks.
