An injunction sought by Ferrari to prevent Formula One's governing body from introducing a budget cap next season will be decided on Wednesday, a French court said.
"A decision on the matter will be announced tomorrow at 1400 (1pm BST)," court president Jacques Gondrand de Robert said after a one-hour hearing today.
Champions Ferrari went to the Tribunal de Grande Instance in Paris to try and stop the International Automobile Federation (FIA) from pressing ahead with the £40m budget cap.
The sport's most successful and glamorous team have threatened to quit Formula One if the published rules are not re-written. Renault, Toyota and Red Bull's two teams have taken a similar stance.
