Summary
WP Venture 4 LLC (WP4) sued Luther Village Owners Corporation (LVOC) to enforce a rent formula in a 99-year Cooperative Ground Lease, seeking back rent calculated at a rate LVOC contended was approximately 50% higher than the parties intended. LVOC counterclaimed for reformation based on mutual mistake. The trial court granted summary judgment for WP4 and third-party defendant Lutheran Home for the Aged (LHA), holding LVOC's reformation claim was time-barred by the 10-year statute of limitations and independently barred by estoppel certificates LVOC signed in 2018 and 2019. The trial court entered a final judgment awarding WP4 $6,426,339.30 in back rent. LVOC appealed.
The appellate court reversed on both grounds. First, it held that the discovery rule — not the execution rule — governs accrual of mutual-mistake reformation claims, reasoning that a party cannot seek reformation until it learns of the mistake. Because the record contained genuine disputes of material fact as to when LVOC knew or should have known of the alleged error — including decades of LHA's own communications confirming rent as 10% of FMV — the limitations question could not be resolved as a matter of law. Second, the court held the estoppel certificates were ambiguous: they listed rent amounts consistent with LVOC's position and confirmed no default, yet neither certificate mentioned the rent-multiplier dispute despite WP4's pre-execution awareness of it.
The court remanded for the trial court to address unresolved alternative grounds including equitable estoppel, laches, and LVOC's burden of proof on reformation. For practitioners, this decision underscores that estoppel certificates must specifically identify known disputes to be effective waivers, and that reformation claims accrue under the discovery rule in Illinois.
Key Holdings
1. The discovery rule governs accrual of reformation claims based on mutual mistake under 735 ILCS 5/13-206; the cause of action accrues when the claimant knew or reasonably should have known of the alleged mistake, not when the contract was executed.
2. When the record contains disputed facts regarding when a party knew or should have known of an alleged contractual mistake, the statute of limitations question cannot be resolved as a matter of law on summary judgment.
3. An estoppel certificate bars only facts specifically set out in the certificate or the course of performance under the lease; a certificate that omits a known dispute and contains provisions consistent with the claimant's position is ambiguous and cannot support summary judgment.
4. An appellate court may decline to affirm summary judgment on alternative grounds not addressed by the trial court and instead remand when multiple unresolved arguments remain.
