Brazil GP reversal: a case of conflict of interest?

[climb]

The decision of FIA to re-give Fisichella his win, reverses a previous and contrary decision who was taken by chronometrists, who favourished Kimi.
But who are the people entrusted of this important service?
Tag-heure, who is at the same time a prime sponsor of McLaren, the car run by Kimi.

Is there, in your opinion, the possibility to talk about a conflict of interest?
Should be the sponsor of a team be entrusted such a delicate activity?
Or, vice versa, is that right that the official chronometer service supplier be allowed to sponsor a team involved in the races they work on?
