Following the Pirelli test, Nico Rosberg won in Monaco
Team boss Ross Brawn has said that he takes full responsibility for the testing mistake
Mercedes has been found guilty of breaking the rules in F1 by using a 2013 car during tests for Pirelli earlier this year.
However, its punishment is relatively minor: it will not be allowed to take part in next month's three-day young driver test at Silverstone.
In a statement, the tribunal announced that Mercedes was guilty of a breach of the regulations and had to be reprimanded. It also deemed that Mercedes had gained an unfair advantage by running a 2013 car in the test.
At the hearing the previous day, Mercedes had argued that a ban from the young driver test would be an appropriate punishment if it was found to have breached the sport's rules, a plea that was heeded by the four-strong tribunal panel.
Pirelli was also reprimanded for its role in the test arrangements.
Mercedes has confirmed it will not appeal the decision.
