Jun.5 - Force India is angry with F1's governing body in the wake of a dispute about race numbers.
Technical boss Andy Green confirmed: "Our car was deemed legal at all times in Barcelona, but suddenly after the race it was said we didn't comply with the rules."
Sporting boss Otmar Szafnauer added: "This is a serious precedent.
"It means every other team can do the same thing also in the technical area. According to this, something that was legal on Thursday is no longer legal on Sunday."
Correspondent Michael Schmidt said the order to penalise Force India came from FIA president Jean Todt.
But Szafnauer would not comment on that, saying only: "We're focusing on ourselves."
