City of Ontario v. Quon
The Supreme Court ruled that a California police department did not violate an officer's Fourth Amendment rights when it reviewed transcripts of text messages he sent on a department-issued pager, because the review was carried out for a legitimate work-related reason and was not excessively intrusive.
Rather than deciding the broader question of how much privacy employees can expect in messages sent on employer-issued devices, the Court resolved the case narrowly by assuming privacy protections applied and finding the search reasonable anyway, leaving the bigger question for another day.
“The judiciary risks error by elaborating too fully on the Fourth Amendment implications of emerging technology before its role in society has become clear.”
The Court explains why it avoided broadly deciding privacy rights for new communication technology.
How it got here: A federal trial court ruled for the police department after a jury trial; the Ninth Circuit reversed on the Fourth Amendment claim; the department asked the Supreme Court to review that ruling.
The Case in Depth
What happened
The City of Ontario issued pagers to police officers, including SWAT team member Jeff Quon, with a monthly limit on text characters. After Quon repeatedly exceeded the limit, the police chief ordered a review of message transcripts to see whether the limit was too low or officers were sending personal messages. The review revealed many of Quon's messages were personal and sexually explicit, and he was disciplined. Quon and others he texted with sued, claiming the search violated their privacy rights.
The question before the Court
Could a police department read the text messages an officer sent on a pager the department had issued him, without violating his Fourth Amendment rights?
The Court's answer
No — the Court found the police department's review of the text messages was reasonable, so it did not violate the Fourth Amendment. Rather than settling how much privacy employees generally have in messages sent on employer-issued devices, the Court sidestepped that question by simply assuming privacy protections applied and asking whether the search itself was reasonable.
It found the search justified because the chief ordered it for a legitimate, non-snooping reason (checking whether the pager plan's character limit was adequate), and the search was not too broad because officials reviewed only two months of messages and redacted off-duty texts. The Court also rejected the idea that a less intrusive method should have been used instead, since the Fourth Amendment only requires reasonableness, not the least intrusive option available.

Why it matters
Government employers who issue phones, pagers, or similar devices to workers can review those communications for legitimate, work-related reasons without automatically violating the Fourth Amendment, as long as the review isn't broader than necessary. The ruling gives public employers practical guidance for auditing electronic devices while leaving unresolved how much privacy employees can expect in personal messages sent on work equipment.
What changes now
This is a final merits decision, not a temporary order. The case is sent back to the lower courts for further proceedings consistent with the ruling that the search was reasonable. The Court deliberately left open the broader question of how much privacy employees can expect in personal communications on employer-issued devices, so future disputes involving other workplaces or newer technologies will need to be litigated separately.
What this does not decide
The Court did not decide whether Quon actually had a reasonable expectation of privacy in his text messages, or which of the competing legal tests from a 1987 case should govern that question generally. It resolved the case by assuming privacy protections applied and finding the search reasonable anyway, leaving the broader privacy-expectation question for future cases.
Concurrences and dissents
Concurrence — Justice Stevens
Justice Stevens agreed with the majority's decision not to resolve which legal test governs an employee's privacy expectations. He highlighted a third approach from a dissenting opinion in the 1987 O'Connor case, which would judge privacy expectations case-by-case rather than under a categorical rule, and noted that all three competing approaches would produce the same result here.
Concurrence in part — Justice Scalia
Justice Scalia joined the Court's opinion except for the portion discussing the parties' arguments about whether a privacy expectation existed, calling that discussion unnecessary and self-defeating since it was irrelevant to the outcome. He argued the Court should have simply held that the search was reasonable and stopped there, criticizing the majority for hedging on how the Fourth Amendment applies to new technology.
How the Court got there
The legal reasoning, step by step
- Rather than deciding whether Quon had a reasonable expectation of privacy in his text messages, the Court assumed for the sake of argument that he did, that reviewing the transcript counted as a Fourth Amendment search, and that the same rules governing physical office searches apply to electronic messages, in order to resolve the case on narrower grounds.
- The Court applied the 'special needs' framework from O'Connor v. Ortega, a 1987 case addressing government-employer searches, under which a warrantless workplace search is reasonable if it is justified at the outset and not excessively broad given the reasons for the search.
- Applying that framework, the Court found the search justified at its inception because the police chief ordered it to determine whether the pager contract's character limit was adequate for legitimate department needs, not to snoop on personal activity.
- The Court found the scope of the search reasonable because the department reviewed only two months of messages, out of many months of overages, and redacted messages sent while the officer was off duty, which limited the intrusion into personal matters.
- The Court also concluded the same result would follow under a competing approach from a separate opinion in O'Connor, which asks whether a search would be considered reasonable and normal between a private employer and employee, since the department's reasons and limited scope would satisfy that standard too.
- The Court rejected the appeals court's reasoning that the search was unreasonable because less intrusive methods existed, explaining that the Fourth Amendment does not require employers to use the least intrusive method available, only a reasonable one.
