I think there is a standing request from Ferrari that any infringement by McClaren is always investigated and then punished to the maximum extent of the rules
McClaren may not be allowed to appeal the penalty though due to the existing rules. The penalty deemed appropriate was a drive through but as the race was already complete it was implemented as a 25 second penalty. The rules do not allow teams to contest/appeal against drive-through penalties
Definitely a case of dual standards after Massa got away with a slap on the wrists for a dangerous incident in the pit lane a couple of races ago.
This was a great race that I really enjoyed watching, particularly during the closing few laps when things got really interesting when the rain came. Shame the Stewards felt it necessary to take the shine off it.
