The FIA have launched an investigation into how Felipe Massa got away with starting the Belgian GP slight ahead of his grid slot.
Massa started Sunday's race with his Ferrari a foot, if not more, ahead of his grid slot, however, race director Charlie Whiting was not made aware of the infringement as the electronic system on the grid did not pick it up.
And as none of Ferrari's rivals noticed the error, the Brazilian avoided a jump start penalty.
The FIA are now set to investigate the matter, although have stated that the Belgian GP result and Massa's fourth-placed finish will stand.
"The problem was not brought to the attention of the FIA race director by either the marshals nor the automatic jump start system in time to be able to apply the appropriate penalty for jump starts," said an FIA spokeswoman.
"As no further information or complaints were received before the publication of the official result on Sunday night, the classification of the Belgian Grand Prix will now remain unchanged.
"The FIA are investigating the causes of the apparent failures in communication with race control in order to ensure a repetition is not possible."
