Max Mosley has denied claims that his rule-changes are up for discussion.
The FIA president said radical reforms like the end of traction control and semi-automatic gearboxes will happen whether the current teams like it or not.
From 1 January 2008, the current Concorde Agreement is no longer in force.
'So the FIA can do whatever it wants,' said Mosley in Imola. 'People just have to decide whether they want to enter the 2008 championship.'
Hard decision.
