Whether the plaintiff’s promise of total abstinence was consideration for the additional $4 per page or instead a condition of performance that the defendant could waive.
Holding
It was a condition precedent to receiving the additional compensation, not independent consideration for that compensation, and it was therefore waivable.
Reasoning
Read as a whole, the agreement was a contract for the plaintiff to write satisfactory books, not a bargain in which the defendant purchased abstinence itself. The abstinence clause served the practical purpose of ensuring competent work and stood alongside other provisions governing the manner and timing of performance.
The contract identified $6 per page as the value of the plaintiff’s normal work. The initial $2 per page was an advance or partial payment, while the remaining $4 per page was withheld pending compliance with stated conditions, including abstinence. Thus, abstinence did not supply the consideration for the higher price; failure to abstain merely triggered a forfeiture of part of an agreed compensation amount.
Like the other substantial performance conditions in the agreement, the abstinence requirement was an incident of performance that the defendant could either enforce or relinquish. If the defendant waived that condition, it could no longer invoke the related forfeiture, although it could still seek damages actually caused by the breach.
