The mother of Mark Duggan, who was fatally shot by police in 2011, has been given permission to challenge the inquest verdict that he was lawfully killed.
A judge ruled that Pamela Duggan can apply for a review after her lawyers claimed the coroner's direction to the jury was "arguably inadequate".
An inquest jury had previously concluded that Mark Duggan was lawfully killed by a police marksman in August 2011 in Tottenham, north London.
Mrs Duggan's lawyers will contend that the coroner did not address questions which, if they had been addressed, meant the lawful killing verdict could not stand at a hearing to take place at a later date.
The judge said the case should go before a panel of judges including either the Lord Chief Justice, Lord Thomas, or the President of the Queen's Bench Division, Sir Brian Leveson.
