Mitch Evans has questioned the decision to allow Lewis Hamilton and Mercedes to keep their win in the Italian Grand Prix after he was slapped with a penalty in GP2 for a similar offence.

The New Zealander was excluded from qualifying at Monza in GP2 after it was found the tyre pressures on his Russian Time car were below the minimum limit, dropping him from the front row to the back of the grid.

Ironically, Evans went on to enjoy his best race weekend of the season, producing a charging drive from the back of the grid in the feature race to finish third, before taking victory in the sprint race with a last lap pass on Arthur Pic.

Even so, Evans took to his Twitter account to air his frustration at the lack of 'consistency', before using the hashtag 'circus' to describe the double standard

Though it was accepted that Hamilton ran with reduced tyre pressures on his Mercedes, it was deemed the team had followed correct protocol as set out by the regulations and thus had not intended to gain an advantage. As a result, the decision was taken not to punish Hamilton with any form of penalty, with the protocol itself now being reviewed instead.
