The family of Jean Charles de Menezes have said they are "crushed" by an IPCC decision not to recommend disciplinary action against the police officers whose actions led to the Tulse Hill resident's death.
The IPCC announced on Friday that it will not be changing its 2005 decision not to take action.
They had reviewed the decision at the request of Mr Menezes' family, and following the open verdict recorded last December at an inquest into the Brazilian electrician's fatal shooting by police firearms officers.
He was shot dead on July 22, 2005, in Stockwell Tube station, after he was mistaken for terror suspect Hussain Osman days after a failed bombing attempt on London’s transport network.
The IPCC said in making the decision it had carefully considered the family’s representations, and the evidence identified by its own investigation and all subsequent legal proceedings.
But a spokesperson for the family said the decision "gave a green light to police officers to act with impunity”.
She added: "The family are not surprised but crushed that the IPCC have ignored the narrative verdict the jury gave at Jean Charles' inquest."
Among the officers who have been considered for disciplinary action are the two marksmen who pulled the trigger and senior officers behind the operation, including Cressida Dick, now an assistant commissioner and Scotland Yard's most senior female officer.
An agreement is expected later this year between the family and police over compensation.
