McMichael v. Price
McMichael v. Price, 58 P.2d 549, was a case decided by the Supreme Court of Oklahoma that held that a constraint on discretion was enough to ensure mutuality of obligation in a requirements contract.
Factual background
The plaintiff Harley T. Price formed a contract with defendant W.M. McMichael to enter the sand business, Sooner Sand Company on February 25, 1929. Specifically, part of the contract read that:agrees to purchase and accept from all of the sand... which can sell..."
When McMichael refused to sell the sand, Price sued for breach of contract in Tulsa county. The trial jury found for plaintiff Price, and McMichael appealed.
