Whether sending unwanted e-mails through a company’s computer system constitutes actionable trespass to chattels when the messages neither damage nor impair the functioning of the system.
Holding
No. Under California law, trespass to chattels requires actual or threatened injury to the personal property or to the possessor’s legally protected interest in that property; harmless electronic communications do not satisfy that requirement.
Reasoning
Trespass to chattels protects possessory interests in personal property against interferences that fall short of conversion. Modern California law, consistent with the Restatement Second of Torts, requires more than a technical or harmless touching: absent dispossession, the plaintiff must show impairment of the chattel’s condition, quality, or value; substantial deprivation of its use; or harm to another legally protected interest connected to the chattel.
The fact that Intel sought an injunction rather than damages did not eliminate the injury requirement. Injunctive relief ordinarily requires a threatened irreparable injury, and it would make little sense to award an injunction for trespass to chattels without proof of the injury that is an element of that tort.
Intel showed no damage to its hardware or software, no system slowdown, no measurable loss of processing capacity or storage, no marginal operating cost, and no substantial deprivation of use. Hamidi used the e-mail system for its designed function—communicating with Intel employees—and the system delivered the messages as intended.
The court distinguished spam and automated web-search cases such as CompuServe, Thrifty-Tel, and eBay. Those cases involved actual or threatened burdens on computer functionality, including depleted storage, reduced processing power, blocked access, or the risk that widespread imitation would overload the system. Hamidi sent only six messages over 21 months, and Intel showed neither functional impairment nor a comparable risk of cumulative system harm.
Intel’s asserted productivity loss arose from the messages’ ideas and content, not from any interference with its computers as property. Treating employees’ distraction from unwelcome speech as injury to the devices that transmitted the speech would stretch trespass to chattels far beyond its possessory foundation. The same theory could transform unwelcome telephone calls, faxes, radio signals, or letters into trespasses against the recipient’s communications equipment.
Intel also could not create the required injury by pointing to the staff time spent trying to block Hamidi’s mail. The costs incurred to prevent an asserted tort cannot themselves establish that the completed tort injured the chattel; otherwise, a plaintiff could manufacture injury through its own efforts to stop unwanted conduct.
