“In determining whether a breach of a contract had been repudiatory an important factor to be taken into account was whether, although serious, the breach had been remedied before the injured party had purported to exercise a right of termination of the contract. Likewise, if there had been delay in performance of an ongoing obligation, it might be possible for the delay to be made up by faster performance. The court had to consider the position as at the date when the injured party purported to terminate. In the absence of time being of the essence, delay would only become a repudiatory breach if it were so prolonged as to frustrate the contract.”
