William and Shirley Nahn owned 1.26 undeveloped acres in St. Louis County. In June 1986, they gave Donald Soffer a one-year option to buy the property. The option could be accepted by written notice by June 28, 1987. It did not set a closing date, but it allowed Soffer or an assignee to cancel the option or any resulting purchase contract if they could not obtain the governmental ordinance or permit needed for their intended business.
Soffer sent written notice on June 10, 1987 that he was exercising the option, subject to its terms. The Nahns responded after the option period ended that, because the sale had not closed by June 28, the option had expired. Soffer maintained that his timely acceptance had formed a binding purchase contract and said he would pursue appropriate zoning. He later assigned his interest to Ten-Eighteen Investment Corporation, a corporation he used to conceal his identity.
Ten-Eighteen subsequently gave Shell Oil an option to purchase the property, and Shell filed a rezoning petition in June 1988. Shell withdrew the petition in February 1989. After the Nahns again denied that Soffer had any interest in the land, Soffer notified them that he would close in March 1989—approximately twenty-one months after exercising the option. During that period, the land's value rose from about $200,000 to between $300,000 and $350,000, and Soffer did not pay property taxes as the option required.
The Nahns brought a quiet-title action. Soffer and Ten-Eighteen counterclaimed for specific performance. After a bench trial, the circuit court quieted title in the Nahns and denied specific performance. Because neither party requested detailed findings, the appellate court assumed the trial court resolved factual issues consistently with its judgment and affirmed if any reasonable legal theory supported it.
