Formula 1 team bosses are unhappy with the FIA after paddock speculation linked former F1 technical department head Marcin Budkowski to Renault.
Budkowski handed his resignation into the FIA this week and has therefore been placed on gardening leave, however he is expected to join Renault once that leave is up, with suggestions it could be just three months until he is working with the French team.
Red Bull team boss Christian Horner said his team would take "major issue" with the FIA if that were the case, given the amount of information Budkowski has on current and future developments up and down the grid.
As head of the sport's technical department, Budkowski is in a privileged position which allows him access to team data, future developments and engine information which, in a rival teams hands, would potentially provide a massive advantage.
Therefore team bosses are set to take a stand and force a minimum 12-month leave period for any FIA employee with sensitive information.
"We will take major issue with that if he does end up in another team," said Horner. "In these individuals, you place an enormous of trust in the role that Marcin has been responsible for.
"He has been in an extremely privileged position where he has extremely recently been in people's wind tunnels and been looking at intimate details of knowledge of next year's cars.
"I think three months notice period and for him to then turn up in a competitor team in F1, is entirely inappropriate," he added. "I hope that isn't the case and I am sure it will get discussed quite seriously at the next Strategy Group meeting."
Sauber team boss Fred Vasseur agreed and said it would have wider consequences: "We need to know where Marcin will go, but it is a big issue.
"The FIA is fully aware of all the details of the team's project, and if we cannot be open with the FIA it is a tricky situation. It is important to know where Marcin will go."
Force India's Otmar Szafnauer insisted a 12-month period should be enforced.
"It would have been nice to know the notice period. Three months I don't think is long enough. I think a year, it has to be long enough such that the technology he is aware of is not obsolete but not leading edge."
