If a contract has already been awarded and it is too far along, we could decide to negotiate a settlement rather than to terminate the contract and start the process all over again. Usually, if the contract is already being executed, the tribunal considers that. Possibly, a contract may have been put into operation quite quickly. If that is so, it might be said that it is impossible to fulfill the conditions.
