An Ipswich man's 32-year fight to clear his name is to be discussed over the next two days at the Royal Court of Justice.
Oliver Campbell, from Ipswich, was convicted in 1991 of murder by shooting and conspiracy to rob.
A reported confession during a police interview was used as a key part of evidence, but Mr Campbell said he was "put under pressure" to admit to a crime he didn't commit.
He had also been interviewed over the course of 14 separate police interrogations, many without a lawyer being present.
Mr Campbell, who has severe learning difficulties after suffering severe brain damage as a baby, has lived in Suffolk ever since finishing his 11-year jail sentence at Hollesley Bay Prison near Woodbridge.
His lawyers, Michael Birnbaum and Glyn Maddocks, said that the evidence against Mr Campbell was that the shooter had worn his distinctive cap, a "deeply flawed" identification and a series of admissions made in the absence of a solicitor.
They went on to state: "The conduct of the Met officers who interviewed him was incompetent and, or, dishonest and manipulative."
Mr Birnbaum and Mr Maddocks, with the assistance of Rose Slowe as junior counsel, will be presenting evidence on Oliver's behalf at the Court of Appeal.
They said: "We can’t give Oliver back 30 lost years.
"But hopefully, we can persuade the Court at long last to recognise the injustice done to him."
Mr Maddocks said, back in November 2022, when they heard they could appeal Mr Campbell's case: "He was convicted for something he absolutely did not do, and I would argue could not have done physically."
Mr Campbell's case will be discussed over two days at the Royal Courts of Justice in London, on February 28 and 29.
