The officer, known only as W80, shot Jermaine Baker as police stopped a plot to snatch two prisoners from a van near Wood Green Crown Court in December 2015.
The Metropolitan Police misconduct hearing at Palestra House was thrown out on Wednesday, October 15.
Chairman of the hearing panel Chris McKay said: “The decision of the panel is that we find there is no case for W80 to answer in these proceedings and accordingly the case against W80 is dismissed.
“The full reasons will follow as the rules provide in the next five working days.”
Father-of-two Mr Baker, from Tottenham, was shot at close range by counter-terrorism specialist firearms officer W80, who thought he was reaching for a gun.
Mr Baker, who was sitting in the front passenger seat of a stolen Audi A6, was unarmed and an imitation firearm was later found in the back of the Audi, the misconduct hearing previously heard.
The misconduct proceedings involving W80 began last week after years of legal battles over the case, in which he is accused of breaching professional standards over the use of force.
Mr Baker was among a group of men trying to free Izzet Eren and his co-defendant as they were transported from Wormwood Scrubs to be sentenced for a firearms offence.
A number of men were jailed in 2016 for their parts in the plot.
