Intel Corp. v. Hamidi

WERDEGAR, J.

Intel Corporation (Intel) maintains an electronic mail system, connected to the Internet, through which messages between employees and those outside the company can be sent and received, and permits its employees to make reasonable nonbusiness use of this system. On six occasions over almost two years, Kourosh Kenneth Hamidi, a former Intel employee, sent e-mails criticizing Intel's employment practices to numerous current employees on Intel's electronic mail system. Hamidi breached no computer security barriers in order to communicate with Intel employees. He offered to, and did, remove from his mailing list any recipient who so wished. Hamidi's communications to individual Intel employees caused neither physical damage nor functional disruption to the company's computers, nor did they at any time deprive Intel of the use of its computers. The contents of the messages, however, caused discussion among employees and managers.

On these facts, Intel brought suit, claiming that by communicating with its employees over the company's e-mail system Hamidi committed the tort of trespass to chattels. The trial court granted Intel's motion for summary judgment and enjoined Hamidi from any further mailings. A divided Court of Appeal affirmed.

After reviewing the decisions analyzing unauthorized electronic contact with computer systems as potential trespasses to chattels, we conclude that under California law the tort does not encompass, and should not be extended to encompass, an electronic communication that neither damages the recipient computer system nor impairs its functioning. Such an electronic communication does not constitute an actionable trespass to personal property, i.e., the computer system, because it does not interfere with the possessor's use or possession of, or any other legally protected interest in, the personal property itself. . . . The consequential economic damage Intel claims to have suffered, i.e., loss of productivity caused by employees reading and reacting to Hamidi's messages and company efforts to block the messages, is not an injury to the company's interest in its computers--which worked as intended and were unharmed by the communications--any more than the personal distress caused by reading an unpleasant letter would be an injury to the recipient's mailbox, or the loss of privacy caused by an intrusive telephone call would be an injury to the recipient's telephone equipment.

Our conclusion does not rest on any special immunity for communications by electronic mail; we do not hold that messages transmitted through the Internet are exempt from the ordinary rules of tort liability. To the contrary, e-mail, like other forms of communication, may in some circumstances cause legally cognizable injury to the recipient or to third parties and may be actionable under various common law or statutory theories. Indeed, on facts somewhat similar to those here, a company or its employees might be able to plead causes of action for interference with prospective economic relations. . . . And, of course, as with any other means of publication, third party subjects of e-mail communications may under appropriate facts make claims for defamation, publication of private facts, or other speech-based torts. . . . Intel's claim fails not because e-mail transmitted through the Internet enjoys unique immunity, but because the trespass to chattels tort--unlike the causes of action just mentioned--may not, in California, be proved without evidence of an injury to the plaintiff's personal property or legal interest therein.

Nor does our holding affect the legal remedies of Internet service providers (ISP's) against senders of unsolicited commercial bulk e-mail (UCE), also known as "spam." . . . A series of federal district court decisions, beginning with CompuServe, Inc. v. Cyber Promotions, Inc. . . . has approved the use of trespass to chattels as a theory of spammers' liability to ISP's, based upon evidence that the vast quantities of mail sent by spammers both overburdened the ISP's own computers and made the entire computer system harder to use for recipients, the ISP's customers. . . . In those cases, discussed in greater detail below, the underlying complaint was that the extraordinary quantity of UCE impaired the computer system's functioning. In the present case, the claimed injury is located in the disruption or distraction caused to recipients by the contents of the e-mail messages, an injury entirely separate from, and not directly affecting, the possession or value of personal property.

FACTUAL AND PROCEDURAL BACKGROUND

Hamidi, a former Intel engineer, together with others, formed an organization named Former and Current Employees of Intel (FACE-Intel) to disseminate information and views critical of Intel's employment and personnel policies and practices. FACE-Intel maintained a Web site (which identified Hamidi as Webmaster and as the organization's spokesperson) containing such material. In addition, over a 21-month period Hamidi, on behalf of FACE-Intel, sent six mass e-mails to employee addresses on Intel's electronic mail system. The messages criticized Intel's employment practices, warned employees of the dangers those practices posed to their careers, suggested employees consider moving to other companies, solicited employees' participation in FACE-Intel, and urged employees to inform themselves further by visiting FACE-Intel's Web site. The messages stated that recipients could, by notifying the sender of their wishes, be removed from FACE-Intel's mailing list; Hamidi did not subsequently send messages to anyone who requested removal.

Each message was sent to thousands of addresses (as many as 35,000 according to FACE-Intel's Web site), though some messages were blocked by Intel before reaching employees. Intel's attempt to block internal transmission of the messages succeeded only in part; Hamidi later admitted he evaded blocking efforts by using different sending computers. When Intel, in March 1998, demanded in writing that Hamidi and FACE-Intel stop sending e-mails to Intel's computer system, Hamidi asserted the organization had a right to communicate with willing Intel employees; he sent a new mass mailing in September 1998.

The summary judgment record contains no evidence Hamidi breached Intel's computer security in order to obtain the recipient addresses for his messages; indeed, internal Intel memoranda show the company's management concluded no security breach had occurred. Hamidi stated he created the recipient address list using an Intel directory on a floppy disk anonymously sent to him. Nor is there any evidence that the receipt or internal distribution of Hamidi's electronic messages damaged Intel's computer system or slowed or impaired its functioning. Intel did present uncontradicted evidence, however, that many employee recipients asked a company official to stop the messages and that staff time was consumed in attempts to block further messages from FACE-Intel. According to the FACE-Intel Web site, moreover, the messages had prompted discussions between "[e]xcited and nervous managers" and the company's human resources department. . . .

We granted Hamidi's petition for review.

DISCUSSION

I. Current California Tort Law

Dubbed by Prosser the "little brother of conversion," the tort of trespass to chattels allows recovery for interferences with possession of personal property "not sufficiently important to be classed as conversion, and so to compel the defendant to pay the full value of the thing with which he has interfered." . . .

Though not amounting to conversion, the defendant's interference must, to be actionable, have caused some injury to the chattel or to the plaintiff's rights in it. Under California law, trespass to chattels "lies where an intentional interference with the possession of personal property has proximately caused injury." Thrifty-Tel, Inc. v. Bezenek (1996) . . . In cases of interference with possession of personal property not amounting to conversion, "the owner has a cause of action for trespass or case, and may recover only the actual damages suffered by reason of the impairment of the property or the loss of its use." . . . In modern American law generally, "[t]respass remains as an occasional remedy for minor interferences, resulting in some damage, but not sufficiently serious or sufficiently important to amount to the greater tort" of conversion. . . .

The Restatement, too, makes clear that some actual injury must have occurred in order for a trespass to chattels to be actionable. Under section 218 of the Restatement Second of Torts, dispossession alone, without further damages, is actionable . . ., but other forms of interference require some additional harm to the personal property or the possessor's interests in it. . . . "The interest of a possessor of a chattel in its inviolability, unlike the similar interest of a possessor of land, is not given legal protection by an action for nominal damages for harmless intermeddlings with the chattel. In order that an actor who interferes with another's chattel may be liable, his conduct must affect some other and more important interest of the possessor. Therefore, one who intentionally intermeddles with another's chattel is subject to liability only if his intermeddling is harmful to the possessor's materially valuable interest in the physical condition, quality, or value of the chattel, or if the possessor is deprived of the use of the chattel for a substantial time, or some other legally protected interest of the possessor is affected as stated in Clause (c). Sufficient legal protection of the possessor's interest in the mere inviolability of his chattel is afforded by his privilege to use reasonable force to protect his possession against even harmless interference." . . .

The Court of Appeal . . . referred to " 'a number of very early cases [showing that] any unlawful interference, however slight, with the enjoyment by another of his personal property, is a trespass.' " But while a harmless use or touching of personal property may be a technical trespass . . ., an interference (not amounting to dispossession) is not actionable, under modern California and broader American law, without a showing of harm. As already discussed, this is the rule embodied in the Restatement (Rest.2d Torts, § 218) and adopted by California law. . . .

In this respect, as Prosser explains, modern day trespass to chattels differs both from the original English writ and from the action for trespass to land: "Another departure from the original rule of the old writ of trespass concerns the necessity of some actual damage to the chattel before the action can be maintained. Where the defendant merely interferes without doing any harm--as where, for example, he merely lays hands upon the plaintiff's horse, or sits in his car--there has been a division of opinion among the writers, and a surprising dearth of authority. By analogy to trespass to land there might be a technical tort in such a case . . . . Such scanty authority as there is, however, has considered that the dignitary interest in the inviolability of chattels, unlike that as to land, is not sufficiently important to require any greater defense than the privilege of using reasonable force when necessary to protect them. Accordingly it has been held that nominal damages will not be awarded, and that in the absence of any actual damage the action will not lie." (Prosser & Keeton, Torts. . . .)

Intel suggests that the requirement of actual harm does not apply here because it sought only injunctive relief, as protection from future injuries. But as Justice Kolkey, dissenting below, observed, "[t]he fact the relief sought is injunctive does not excuse a showing of injury, whether actual or threatened." Indeed, in order to obtain injunctive relief the plaintiff must ordinarily show that the defendant's wrongful acts threaten to cause irreparable injuries, ones that cannot be adequately compensated in damages. . . . Even in an action for trespass to real property, in which damage to the property is not an element of the cause of action, "the extraordinary remedy of injunction" cannot be invoked without showing the likelihood of irreparable harm. . . . A fortiori, to issue an injunction without a showing of likely irreparable injury in an action for trespass to chattels, in which injury to the personal property or the possessor's interest in it is an element of the action, would make little legal sense.

The dispositive issue in this case, therefore, is whether the undisputed facts demonstrate Hamidi's actions caused or threatened to cause damage to Intel's computer system, or injury to its rights in that personal property, such as to entitle Intel to judgment as a matter of law. . . .

Relying on a line of decisions, most from federal district courts, applying the tort of trespass to chattels to various types of unwanted electronic contact between computers, Intel contends that, while its computers were not damaged by receiving Hamidi's messages, its interest in the "physical condition, quality or value" . . . of the computers was harmed. We disagree. The cited line of decisions does not persuade us that the mere sending of electronic communications that assertedly cause injury only because of their contents constitutes an actionable trespass to a computer system through which the messages are transmitted. Rather, the decisions finding electronic contact to be a trespass to computer systems have generally involved some actual or threatened interference with the computers' functioning. . . .

In the leading case, eBay, the defendant Bidder's Edge (BE), operating an auction aggregation site, accessed the eBay Web site about 100,000 times per day, accounting for between 1 and 2 percent of the information requests received by eBay and a slightly smaller percentage of the data transferred by eBay. . . . The district court rejected eBay's claim that it was entitled to injunctive relief because of the defendant's unauthorized presence alone, or because of the incremental cost the defendant had imposed on operation of the eBay site . . ., but found sufficient proof of threatened harm in the potential for others to imitate the defendant's activity: "If BE's activity is allowed to continue unchecked, it would encourage other auction aggregators to engage in similar recursive searching of the eBay system such that eBay would suffer irreparable harm from reduced system performance, system unavailability, or data losses.". . . Again, in addressing the likelihood of eBay's success on its trespass to chattels cause of action, the court held the evidence of injury to eBay's computer system sufficient to support a preliminary injunction: "If the court were to hold otherwise, it would likely encourage other auction aggregators to crawl the eBay site, potentially to the point of denying effective access to eBay's customers. If preliminary injunctive relief were denied, and other aggregators began to crawl the eBay site, there appears to be little doubt that the load on eBay's computer system would qualify as a substantial impairment of condition or value." . . .

In the decisions so far reviewed, the defendant's use of the plaintiff's computer system was held sufficient to support an action for trespass when it actually did, or threatened to, interfere with the intended functioning of the system, as by significantly reducing its available memory and processing power. . . .

That Intel does not claim the type of functional impact that spammers and robots have been alleged to cause is not surprising in light of the differences between Hamidi's activities and those of a commercial enterprise that uses sheer quantity of messages as its communications strategy. Though Hamidi sent thousands of copies of the same message on six occasions over 21 months, that number is minuscule compared to the amounts of mail sent by commercial operations. The individual advertisers sued in America Online, Inc. v. IMS . . . and America Online, Inc. v. LCGM, Inc. . . . were alleged to have sent more than 60 million messages over 10 months and more than 92 million messages over seven months, respectively. Collectively, UCE has reportedly come to constitute about 45 percent of all e-mail. . . . The functional burden on Intel's computers, or the cost in time to individual recipients, of receiving Hamidi's occasional advocacy messages cannot be compared to the burdens and costs caused ISP's and their customers by the ever-rising deluge of commercial e-mail. . . .

In addition to impairment of system functionality, CompuServe and its progeny also refer to the ISP's loss of business reputation and customer goodwill, resulting from the inconvenience and cost that spam causes to its members, as harm to the ISP's legally protected interests in its personal property. . . . Intel argues that its own interest in employee productivity, assertedly disrupted by Hamidi's messages, is a comparable protected interest in its computer system. We disagree.

Whether the economic injuries identified in CompuServe were properly considered injuries to the ISP's possessory interest in its personal property, the type of property interest the tort is primarily intended to protect . . ., has been questioned. "[T]he court broke the chain between the trespass and the harm, allowing indirect harms to CompuServe's business interests--reputation, customer goodwill, and employee time--to count as harms to the chattel (the server).". . . "[T]his move cuts trespass to chattels free from its moorings of dispossession or the equivalent, allowing the court free reign [sic] to hunt for 'impairment.' " . . . But even if the loss of goodwill identified in CompuServe were the type of injury that would give rise to a trespass to chattels claim under California law, Intel's position would not follow, for Intel's claimed injury has even less connection to its personal property than did CompuServe's.

CompuServe's customers were annoyed because the system was inundated with unsolicited commercial messages, making its use for personal communication more difficult and costly. ( CompuServe, supra, 962 F. Supp. at p. 1023.) Their complaint, which allegedly led some to cancel their CompuServe service, was about the functioning of CompuServe's electronic mail service. Intel's workers, in contrast, were allegedly distracted from their work not because of the frequency or quantity of Hamidi's messages, but because of assertions and opinions the messages conveyed. Intel's complaint is thus about the contents of the messages rather than the functioning of the company's e-mail system. Even accepting CompuServe's economic injury rationale, therefore, Intel's position represents a further extension of the trespass to chattels tort, fictionally recharacterizing the allegedly injurious effect of a communication's contents on recipients as an impairment to the device which transmitted the message.

This theory of "impairment by content" . . . threatens to stretch trespass law to cover injuries far afield from the harms to possession the tort evolved to protect. Intel's theory would expand the tort of trespass to chattels to cover virtually any unconsented-to communication that, solely because of its content, is unwelcome to the recipient or intermediate transmitter. As the dissenting justice below explained, " 'Damage' of this nature--the distraction of reading or listening to an unsolicited communication--is not within the scope of the injury against which the trespass-to-chattel tort protects, and indeed trivializes it. After all, '[t]he property interest protected by the old action of trespass was that of possession; and this has continued to affect the character of the action.' . . . Reading an e-mail transmitted to equipment designed to receive it, in and of itself, does not affect the possessory interest in the equipment. [P] Indeed, if a chattel's receipt of an electronic communication constitutes a trespass to that chattel, then not only are unsolicited telephone calls and faxes trespasses to chattel, but unwelcome radio waves and television signals also constitute a trespass to chattel every time the viewer inadvertently sees or hears the unwanted program." We agree. While unwelcome communications, electronic or otherwise, can cause a variety of injuries to economic relations, reputation and emotions, those interests are protected by other branches of tort law; in order to address them, we need not create a fiction of injury to the communication system.

Nor may Intel appropriately assert a property interest in its employees' time. "The Restatement test clearly speaks in the first instance to the impairment of the chattel. . . . But employees are not chattels (at least not in the legal sense of the term)." Whatever interest Intel may have in preventing its employees from receiving disruptive communications, it is not an interest in personal property, and trespass to chattels is therefore not an action that will lie to protect it. Nor, finally, can the fact Intel staff spent time attempting to block Hamidi's messages be bootstrapped into an injury to Intel's possessory interest in its computers. To quote, again, from the dissenting opinion in the Court of Appeal: "[I]t is circular to premise the damage element of a tort solely upon the steps taken to prevent the damage. Injury can only be established by the completed tort's consequences, not by the cost of the steps taken to avoid the injury and prevent the tort; otherwise, we can create injury for every supposed tort."

Intel connected its e-mail system to the Internet and permitted its employees to make use of this connection both for business and, to a reasonable extent, for their own purposes. In doing so, the company necessarily contemplated the employees' receipt of unsolicited as well as solicited communications from other companies and individuals. That some communications would, because of their contents, be unwelcome to Intel management was virtually inevitable. Hamidi did nothing but use the e-mail system for its intended purpose--to communicate with employees. The system worked as designed, delivering the messages without any physical or functional harm or disruption. These occasional transmissions cannot reasonably be viewed as impairing the quality or value of Intel's computer system. We conclude, therefore, that Intel has not presented undisputed facts demonstrating an injury to its personal property, or to its legal interest in that property, that support, under California tort law, an action for trespass to chattels.

II. Proposed Extension of California Tort Law

We next consider whether California common law should be extended to cover, as a trespass to chattels, an otherwise harmless electronic communication whose contents are objectionable. We decline to so expand California law. Intel, of course, was not the recipient of Hamidi's messages, but rather the owner and possessor of computer servers used to relay the messages, and it bases this tort action on that ownership and possession. The property rule proposed is a rigid one, under which the sender of an electronic message would be strictly liable to the owner of equipment through which the communication passes--here, Intel--for any consequential injury flowing from the contents of the communication. The arguments of amici curiae and academic writers on this topic, discussed below, leave us highly doubtful whether creation of such a rigid property rule would be wise.

Writing on behalf of several industry groups appearing as amici curiae, Professor Richard A. Epstein of the University of Chicago urges us to excuse the required showing of injury to personal property in cases of unauthorized electronic contact between computers, "extending the rules of trespass to real property to all interactive Web sites and servers." The court is thus urged to recognize, for owners of a particular species of personal property, computer servers, the same interest in inviolability as is generally accorded a possessor of land. In effect, Professor Epstein suggests that a company's server should be its castle, upon which any unauthorized intrusion, however harmless, is a trespass.

Epstein's argument derives, in part, from the familiar metaphor of the Internet as a physical space, reflected in much of the language that has been used to describe it: "cyberspace," "the information superhighway," e-mail "addresses," and the like. Of course, the Internet is also frequently called simply the "Net," a term, Hamidi points out, "evoking a fisherman's chattel." A major component of the Internet is the World Wide "Web," a descriptive term suggesting neither personal nor real property, and "cyberspace" itself has come to be known by the oxymoronic phrase "virtual reality," which would suggest that any real property "located" in "cyberspace" must be "virtually real" property. Metaphor is a two-edged sword.

Indeed, the metaphorical application of real property rules would not, by itself, transform a physically harmless electronic intrusion on a computer server into a trespass. That is because, under California law, intangible intrusions on land, including electromagnetic transmissions, are not actionable as trespasses (though they may be as nuisances) unless they cause physical damage to the real property. . . . Since Intel does not claim Hamidi's electronically transmitted messages physically damaged its servers, it could not prove a trespass to land even were we to treat the computers as a type of real property. Some further extension of the conceit would be required, under which the electronic signals Hamidi sent would be recast as tangible intruders, perhaps as tiny messengers rushing through the "hallways" of Intel's computers and bursting out of employees' computers to read them Hamidi's missives. But such fictions promise more confusion than clarity in the law. . . .

The plain fact is that computers, even those making up the Internet, are--like such older communications equipment as telephones and fax machines--personal property, not realty. Professor Epstein observes that "[a]lthough servers may be moved in real space, they cannot be moved in cyberspace," because an Internet server must, to be useful, be accessible at a known address. But the same is true of the telephone: to be useful for incoming communication, the telephone must remain constantly linked to the same number (or, when the number is changed, the system must include some forwarding or notification capability, a qualification that also applies to computer addresses). Does this suggest that an unwelcome message delivered through a telephone or fax machine should be viewed as a trespass to a type of real property? We think not: As already discussed, the contents of a telephone communication may cause a variety of injuries and may be the basis for a variety of tort actions (e.g., defamation, intentional infliction of emotional distress, invasion of privacy), but the injuries are not to an interest in property, much less real property, and the appropriate tort is not trespass.

More substantively, Professor Epstein argues that a rule of computer server inviolability will, through the formation or extension of a market in computer-to-computer access, create "the right social result." In most circumstances, he predicts, companies with computers on the Internet will continue to authorize transmission of information through e-mail, Web site searching, and page linking because they benefit by that open access. When a Web site owner does deny access to a particular sending, searching, or linking computer, a system of "simple one-on-one negotiations" will arise to provide the necessary individual licenses.

Other scholars are less optimistic about such a complete propertization of the Internet. Professor Mark Lemley of the University of California, Berkeley, writing on behalf of an amici curiae group of professors of intellectual property and computer law, observes that under a property rule of server inviolability, "each of the hundreds of millions of [Internet] users must get permission in advance from anyone with whom they want to communicate and anyone who owns a server through which their message may travel." The consequence for e-mail could be a substantial reduction in the freedom of electronic communication, as the owner of each computer through which an electronic message passes could impose its own limitations on message content or source. As Professor Dan Hunter of the University of Pennsylvania asks rhetorically: "Does this mean that one must read the 'Terms of Acceptable Email Usage' of every email system that one emails in the course of an ordinary day? If the University of Pennsylvania had a policy that sending a joke by email would be an unauthorized use of its system, then under the logic of [the lower court decision in this case], you would commit 'trespass' if you emailed me a . . . cartoon." . . .

Web site linking, Professor Lemley further observes, "would exist at the sufferance of the linked-to party, because a Web user who followed a 'disapproved' link would be trespassing on the plaintiff's server, just as sending an e-mail is trespass under the [lower] court's theory." Another writer warns that "[c]yber-trespass theory will curtail the free flow of price and product information on the Internet by allowing website owners to tightly control who and what may enter and make use of the information housed on its Internet site." (Chang, Bidding on Trespass: eBay, Inc. v. Bidder's Edge, Inc. and the Abuse of Trespass Theory in Cyberspace Law (2001) 29 AIPLA Q.J. 445, 459.) A leading scholar of Internet law and policy, Professor Lawrence Lessig of Stanford University, has criticized Professor Epstein's theory of the computer server as quasi-real property, previously put forward in the eBay case ( eBay, supra, 100 F. Supp. 2d 1058), on the ground that it ignores the costs to society in the loss of network benefits: "eBay benefits greatly from a network that is open and where access is free. It is this general feature of the Net that makes the Net so valuable to users and a source of great innovation. And to the extent that individual sites begin to impose their own rules of exclusion, the value of the network as a network declines. If machines must negotiate before entering any individual site, then the costs of using the network climb." . . .

We discuss this debate among the amici curiae and academic writers only to note its existence and contours, not to attempt its resolution. Creating an absolute property right to exclude undesired communications from one's e-mail and Web servers might help force spammers to internalize the costs they impose on ISP's and their customers. But such a property rule might also create substantial new costs, to e-mail and e-commerce users and to society generally, in lost ease and openness of communication and in lost network benefits. In light of the unresolved controversy, we would be acting rashly to adopt a rule treating computer servers as real property for purposes of trespass law.

The Legislature has already adopted detailed regulations governing UCE. . . . It may see fit in the future also to regulate noncommercial e-mail, such as that sent by Hamidi, or other kinds of unwanted contact between computers on the Internet, such as that alleged in eBay. . . . But we are not persuaded that these perceived problems call at present for judicial creation of a rigid property rule of computer server inviolability. We therefore decline to create an exception, covering Hamidi's unwanted electronic messages to Intel employees, to the general rule that a trespass to chattels is not actionable if it does not involve actual or threatened injury to the personal property or to the possessor's legally protected interest in the personal property. No such injury having been shown on the undisputed facts, Intel was not entitled to summary judgment in its favor.

III. Constitutional Considerations

Because we conclude no trespass to chattels was shown on the summary judgment record, making the injunction improper on common law grounds, we need not address at length the dissenters' constitutional arguments. . . .

DISPOSITION

The judgment of the Court of Appeal is reversed.


Kennard, J., Moreno, J., and Perren, J., * concurred.


Kennard, J.

I concur. Does a person commit the tort of trespass to chattels by making occasional personal calls to a mobile phone despite the stated objection of the person who owns the mobile phone and pays for the mobile phone service? Does it matter that the calls are not made to the mobile phone's owner, but to another person who ordinarily uses that phone? Does it matter that the person to whom the calls are made has not objected to them? Does it matter that the calls do not damage the mobile phone or reduce in any significant way its availability or usefulness?

The majority concludes, and I agree, that using another's equipment to communicate with a third person who is an authorized user of the equipment and who does not object to the communication is trespass to chattels only if the communications damage the equipment or in some significant way impair its usefulness or availability.

Intel Corporation has my sympathy. Unsolicited and unwanted bulk e-mail, most of it commercial, is a serious annoyance and inconvenience for persons who communicate electronically through the Internet, and bulk e-mail that distracts employees in the workplace can adversely affect overall productivity. But, as the majority persuasively explains, to establish the tort of trespass to chattels in California, the plaintiff must prove either damage to the plaintiff's personal property or actual or threatened impairment of the plaintiff's ability to use that property. Because plaintiff Intel has not shown that defendant Kourosh Kenneth Hamidi's occasional bulk e-mail messages to Intel's employees have damaged Intel's computer system or impaired its functioning in any significant way, Intel has not established the tort of trespass to chattels.

This is not to say that Intel is helpless either practically or legally. As a practical matter, Intel need only instruct its employees to delete messages from Hamidi without reading them and to notify Hamidi to remove their workplace e-mail addresses from his mailing lists. Hamidi's messages promised to remove recipients from the mailing list on request, and there is no evidence that Hamidi has ever failed to do so. From a legal perspective, a tort theory other than trespass to chattels may provide Intel with an effective remedy if Hamidi's messages are defamatory or wrongfully interfere with Intel's economic interests. . . . Additionally, the Legislature continues to study the problems caused by bulk e-mails and other dubious uses of modern communication technologies and may craft legislation that accommodates the competing concerns in these sensitive and highly complex areas.

Accordingly, I join the majority in reversing the Court of Appeal's judgment.



BROWN, J., Dissenting.

Candidate A finds the vehicles that candidate B has provided for his campaign workers, and A spray paints the water soluble message, "Fight corruption, vote for A" on the bumpers. The majority's reasoning would find that notwithstanding the time it takes the workers to remove the paint and the expense they incur in altering the bumpers to prevent further unwanted messages, candidate B does not deserve an injunction unless the paint is so heavy that it reduces the cars' gas mileage or otherwise depreciates the cars' market value. Furthermore, candidate B has an obligation to permit the paint's display, because the cars are driven by workers and not B personally, because B allows his workers to use the cars to pick up their lunch or retrieve their children from school, or because the bumpers display B's own slogans. I disagree.

Intel Corporation has invested millions of dollars to develop and maintain a computer system. It did this not to act as a public forum but to enhance the productivity of its employees. Kourosh Kenneth Hamidi sent as many as 200,000 e-mail messages to Intel employees. The time required to review and delete Hamidi's messages diverted employees from productive tasks and undermined the utility of the computer system. "There may . . . be situations in which the value to the owner of a particular type of chattel may be impaired by dealing with it in a manner that does not affect its physical condition." . . . This is such a case.

The majority repeatedly asserts that Intel objected to the hundreds of thousands of messages solely due to their content, and proposes that Intel seek relief by pleading content-based speech torts. This proposal misses the point that Intel's objection is directed not toward Hamidi's message but his use of Intel's property to display his message. Intel has not sought to prevent Hamidi from expressing his ideas on his Web site, through private mail (paper or electronic) to employees' homes, or through any other means like picketing or billboards. But as counsel for Intel explained during oral argument, the company objects to Hamidi's using Intel's property to advance his message.

Of course, Intel deserves an injunction even if its objections are based entirely on the e-mail's content. Intel is entitled, for example, to allow employees use of the Internet to check stock market tables or weather forecasts without incurring any concomitant obligation to allow access to pornographic Web sites. . . . A private property owner may choose to exclude unwanted mail for any reason, including its content. . . .

Those who have contempt for grubby commerce and reverence for the rarified heights of intellectual discourse may applaud today's decision, but even the flow of ideas will be curtailed if the right to exclude is denied. As the Napster controversy revealed, creative individuals will be less inclined to develop intellectual property if they cannot limit the terms of its transmission. Similarly, if online newspapers cannot charge for access, they will be unable to pay the journalists and editorialists who generate ideas for public consumption.

This connection between the property right to objects and the property right to ideas and speech is not novel. James Madison observed, "a man's land, or merchandise, or money is called his property." . . . Likewise, "a man has a property in his opinions and the free communication of them.". . . Accordingly, "freedom of speech and property rights were seen simply as different aspects of an indivisible concept of liberty.". . .

The principles of both personal liberty and social utility should counsel us to usher the common law of property into the digital age.


MOSK, J.

The majority hold that the California tort of trespass to chattels does not encompass the use of expressly unwanted electronic mail that causes no physical damage or impairment to the recipient's computer system. They also conclude that because a computer system is not like real property, the rules of trespass to real property are also inapplicable to the circumstances in this case. Finally, they suggest that an injunction to preclude mass, noncommercial, unwelcome e-mails may offend the interests of free communication.

I respectfully disagree and would affirm the trial court's decision. In my view, the repeated transmission of bulk e-mails by appellant Kourosh Kenneth Hamidi (Hamidi) to the employees of Intel Corporation (Intel) on its proprietary confidential e-mail lists, despite Intel's demand that he cease such activities, constituted an actionable trespass to chattels. The majority fail to distinguish open communication in the public "commons" of the Internet from unauthorized intermeddling on a private, proprietary intranet. Hamidi is not communicating in the equivalent of a town square or of an unsolicited "junk" mailing through the United States Postal Service. His action, in crossing from the public Internet into a private intranet, is more like intruding into a private office mailroom, commandeering the mail cart, and dropping off unwanted broadsides on 30,000 desks. Because Intel's security measures have been circumvented by Hamidi, the majority leave Intel, which has exercised all reasonable self-help efforts, with no recourse unless he causes a malfunction or systems "crash." Hamidi's repeated intrusions did more than merely "prompt[] discussions between '[e]xcited and nervous managers' and the company's human resources department" . . . ; they also constituted a misappropriation of Intel's private computer system contrary to its intended use and against Intel's wishes.
