Walgreen leased space in a shopping center owned by Sara Creek under a long-term lease that contained an exclusivity clause. The landlord promised not to lease other space in the mall to any pharmacy or to a store that operated a pharmacy. Years into the lease, the mall lost a major anchor tenant. To stabilize the center, Sara Creek sought to lease the vacated anchor space to Phar-Mor, a discount retailer that operated an in-store pharmacy as part of its standard format. Allowing Phar-Mor to open with a pharmacy would violate Walgreen's exclusivity right and expose Walgreen to direct intra-mall competition that it had bargained to avoid. Negotiations between Walgreen and Sara Creek to waive or modify the exclusivity provision failed. Walgreen sued to enforce the restrictive covenant and sought a permanent injunction preventing the landlord from leasing to a tenant that would operate a pharmacy. The district court granted a permanent injunction. Sara Creek appealed, arguing that an injunction was unnecessary and inequitable because any harm to Walgreen from added competition could be compensated through money damages. Sara Creek also emphasized the harm to the mall if the Phar-Mor lease fell through and claimed that a damages remedy would avoid the deadweight costs of enjoining a potentially valuable tenancy.
Whether a permanent injunction enforcing a lease's exclusivity clause is appropriate (rather than limiting the tenant to money damages) where damages would be difficult to measure and would require ongoing judicial supervision, and where the landlord argues that an injunction imposes greater hardship by jeopardizing an anchor tenancy.
A permanent injunction is appropriate when the plaintiff demonstrates that legal remedies are inadequate (e.g., damages are difficult to compute or would require repeated proceedings), the balance of hardships favors equitable relief, and the public interest would not be disserved. In choosing between injunction and damages, courts consider comparative institutional competence: if damages would be highly speculative or necessitate ongoing supervision, and if an injunction would better induce efficient private bargaining to price the entitlement, an injunction may be the superior remedy. The grant or denial of a permanent injunction is reviewed for abuse of discretion.
The Seventh Circuit affirmed the district court's grant of a permanent injunction barring Sara Creek from leasing space in the shopping center to a tenant that would operate a pharmacy in violation of Walgreen's exclusivity right.
The court emphasized that damages would be difficult to measure accurately and would likely require repeated litigation and judicial monitoring over time. Estimating Walgreen's lost profits from intra-mall competition by an in-store pharmacy would involve isolating the effect of the competitor's presence from numerous market variables (pricing, promotions, consumer preferences, macroeconomic shifts, and competitive responses). This uncertainty raises the risk of significant error in damages awards and would entail substantial administrative costs if recalculations were required as conditions changed. By contrast, an injunction places the entitlement to exclusivity squarely with Walgreen, allowing the parties—who possess superior information—to bargain over a buyout. If Phar-Mor's tenancy truly creates value that exceeds Walgreen's loss, Sara Creek can negotiate to compensate Walgreen for waiving its exclusivity right. The court acknowledged potential bilateral-monopoly or "holdout" concerns (because dealing involves only these two parties), but concluded those bargaining costs were likely smaller than the judicial costs and error risks inherent in trying to price Walgreen's future losses. Moreover, Sara Creek had voluntarily assumed the risk of the exclusivity restriction when it signed the lease; any hardship resulting from the injunction derived from its own contractual undertaking and did not outweigh Walgreen's bargained-for right. The court also noted that an injunction avoids ongoing judicial supervision of a complex competitive relationship, which courts are ill-suited to manage. Injunctions can be modified if circumstances change dramatically, but the baseline allocation of the entitlement to the promisee of a negative covenant is consistent with both contract enforcement principles and efficient remedies design. Given the district court's careful consideration of these factors, there was no abuse of discretion in preferring an injunction over a damages remedy.
Walgreen is a staple in Remedies for its law-and-economics framing of the injunction-versus-damages choice. It teaches that the "adequate remedy at law" inquiry is not formalistic; it turns on institutional competence, information costs, and error risk. The case also offers an accessible template for balancing hardships and for recognizing when a property-rule remedy (injunction) can induce efficient private bargaining better than a liability-rule remedy (damages). For students, it clarifies how courts analyze negative covenants in leases and when the promisee's entitlement should be protected by an injunction despite the availability of theoretical money damages.
Walgreen Co. v. Sara Creek Property Co. exemplifies how courts should choose remedies with attention to information costs, administrative burdens, and the parties' capacity to bargain. By affirming a permanent injunction, the Seventh Circuit underscores that equitable relief is appropriate when damages would be speculative, require continuing oversight, and risk substantial error.
