PARIS — Motorsport's governing body has reprimanded Mercedes and Pirelli for in-season tire testing that rival teams claimed was unfair.

The disciplinary tribunal of the International Automobile Federation (FIA) also barred the German team from joining other Formula One teams at a planned three-day test session for young drivers in July.

That was the punishment a Mercedes' lawyer had suggested to the tribunal at its hearing in Paris on Thursday.

The tribunal ruling on Friday eliminated concerns that Mercedes could be barred from races or docked points for taking part in the tire tests in May with Pirelli.

The FIA argued at the hearing that those tests, violating a ban on in-season testing, gave the German team an unfair advantage over other teams.
