In the event of an unauthorized commitment where the COR directed the contractor to perform the work not called for/funded by the contract (CR), where the CO doesn't feel that the commitment meets the requirements for ratification set forth in FAR 1.602©(3) and refuses to ratify, what are the options for the government and contractor? Specifically, the contractor can submit a claim or sue the government, but can the contractor take action against the COR specifically? Can the government take action against the COR, holding them liable for the amount of the unauthorized commitment? Are there any cases or examples where this has occurred?
