Case Brief Summary & Legal Analysis

Torts Focus
3 min read

tl;dr: An auto wholesaler sued Toyota for interfering with his business by telling dealers not to sell to him. The court held that to win, the wholesaler must prove Toyota’s actions were independently wrongful, not just that they interfered with his business, thereby protecting legitimate competition.

Legal Significance: This case fundamentally changed California law for the tort of intentional interference with prospective economic relations by shifting the burden of proof to the plaintiff to show the defendant’s conduct was independently wrongful, thereby protecting legitimate business competition from tort liability.

Case Facts & Court Holding

Key Facts & Case Background

Plaintiff John Della Penna was a successful automobile wholesaler who purchased Lexus vehicles from U.S. dealers and exported them for resale in Japan. Defendant Toyota Motor Sales, U.S.A., Inc., concerned that this gray market would undermine its new U.S. Lexus dealer network, implemented a “no export” policy in its dealership agreements. To enforce this policy, Toyota created and distributed an “offenders list” to its dealers, which included Della Penna’s name. Toyota warned its dealers that selling to individuals on the list could result in sanctions, including reduced vehicle allocations or franchise reevaluation. As a result of these actions, Della Penna’s sources for Lexus vehicles dried up, effectively destroying his business. Della Penna sued Toyota for intentional interference with his economic relations. At trial, over the plaintiff’s objection, the judge instructed the jury that Della Penna had to prove Toyota’s interfering conduct was “wrongful.” The jury found for Toyota. The Court of Appeal reversed, holding that wrongfulness was not an element of the plaintiff’s prima facie case.
