Button may have an out from Williams contract

Jenson Button could remain at BAR Honda for 2006, despite seemingly having a watertight contract with Williams, and potentially without BAR Honda needing to spend a fortune buying the contract back. According to a QC consulted by Autosport, Jenson could extricate himself from the Williams contract, arguing that the team bears little relation to the team he signed with, and therefore rendering the contract null and void.
