The family of Mark Duggan, whose fatal shooting by a police marksman sparked nationwide riots, have won permission to go to the Court of Appeal over a finding that he was "lawfully killed".
They are challenging a decision by three High Court judges that an inquest jury was entitled to bring in its 8-2 majority verdict.
Lord Justice Sales allowed their application for permission to launch a full appeal against the High Court ruling.
The judge cautioned the family against thinking his decision meant their appeal must succeed.
But he said their case was "arguable" and added: "I am granting permission on the basis that there is a real prospect of success on appeal."
The judge said: "I also consider a further compelling reason for the grant of permission is that the shooting dead of a suspect by police is always a matter for careful scrutiny."
