Whether the requirement that Oppenheimer deliver the prime landlord's written consent by February 25 was an express condition precedent to formation of the sublease.
Holding
Yes. The agreement unmistakably made timely delivery of written consent an express condition precedent to any contractual relationship or sublease.
Reasoning
A condition precedent is an act or event that must occur before a contractual duty arises. Where the condition goes to the formation or existence of the agreement itself, no contract arises unless and until the condition occurs. That differs from a condition governing performance under an already existing contract.
The parties used unmistakably conditional language: the sublease would not be executed "unless and until" the written-consent condition was timely satisfied, and the agreement would be "null and void" if the consent was not received by the deadline. This language left no plausible basis to construe the requirement as merely a contractual promise or constructive condition.
Although courts generally construe doubtful language against creating an express condition, especially where forfeiture might result, that interpretive preference cannot override clear language. Sophisticated parties in an arm's-length transaction were free to make the landlord's written consent and its timely delivery prerequisites to their bargain.
