According to an official document published by the FIA, "there is no significant and relevant new element" allowing the review of the penalty as desired by the Scuderia. "The motion is therefore dismissed."
Earlier in the day, Sainz and Scuderia representatives were heard by the stewards to determine whether or not there was a significant new element that could lead to a reassessment of the sanction.
The 28-year-old Spaniard was sanctioned in Melbourne for squeezing compatriot Fernando Alonso's Aston-Martin and sending the former world champion into a head-to-tail. Alonso, however, finished third in the race.
The five-second penalty had pushed Sainz from 4th to 12th place, out of the points, as the race had ended under the safety car regime. Ferrari had appealed the sanction.
On Tuesday, the commission ruled that Sainz "was fully responsible for the collision". The Ferrari driver therefore retains his 12th place, a blow for the Prancing Horse team which does not score any points in Australia since Charles Leclerc had to retire after an exit from the track.
In a statement issued in the wake of the FIA's decision, the reigning world vice-champion in the constructors' category acknowledged that it was "disappointed", considering "having provided sufficient significant new elements for the FIA to reconsider the decision".
"We are, however, respectful of the FIA's process and decision," she added.
