Mercedes technical chief Paddy Lowe believes it was "regrettable" that Lewis Hamilton went to the FIA to clarify Nico Rosberg's Hungarian Grand Prix pole lap without speaking to his team.
Hamilton wanted clarification last weekend on Rosberg's lap, which was the fastest in Q3 despite the German having to pass through a double waved yellow flag zone for Fernando Alonso's spun McLaren.
The Formula 1 world champion added, however, that he believed his approach to FIA race director Charlie Whiting had no influence on Rosberg's lap being investigated.
Speaking at the German Grand Prix at Hockenheim on Friday, Lowe said: "It is my understanding that Lewis did go and see Charlie.
"But it wasn't in any way to seek a review of Nico's lap - it was for his own understanding of what should be done in the future, how that should work for him in the future.
"I think that was regrettable. He should have kept to advice from the team and we could have obtained that from Charlie as necessary.
"But I don't think there is any harm [in Hamilton wanting clarification].
"It was just a misjudgement from that point of view."
Rosberg was able to prove that he lifted off enough to satisfy the stewards, although the confusion led to calls from other drivers to clarify what is acceptable under double waved yellow flags - which are supposed to mean a driver should slow down and be prepared to stop.
The result was a change in the rules revealed this week, meaning any time double waved yellows are required in qualifying, the session will now be red flagged.
