If a party to a contract repudiates the contract, or refuses to perform it when the time for performance on his part has arrived, or while the adversary party is performing the contract on his part, such renunciation is held to amount to a breach which operates as a discharge1 even in jurisdictions in which it is held that there can not be a breach by renunciation before the time for performance has arrived.2 If the adversary party has already done everything to be done by him under the terms of the contract, a right of action exists in his favor at once.3 If he has not performed, such breach gives a right of action to the adversary party at once, though he has not performed the covenants of the contract on his part to be performed.4 Breach by renunciation during performance excuses further performance by the adversary party as a condition precedent to recovery on his part.5 Such breach also excuses performance of other acts which by the terms of the contract would have been conditions precedent, which would have to be performed before performance by the adversary party could be required.6 Further demand is not necessary to put the party breaking the contract in default, even if such demand and tender of performance would otherwise be a covenant concurrent with the covenants of the party breaking the contract7 In cases of breach during performance it is no defense that the work done under the contract has been of no benefit to the party in default.8
