City of Ontario v. Quon
The Supreme Court ruled that a California police department did not violate the Fourth Amendment when it reviewed text-message transcripts from a pager it had issued to a SWAT officer, even though many messages turned out to be personal and sexually explicit.
The Court sidestepped the harder question of how much privacy employees generally expect in messages sent on employer-owned devices, deciding the case on the narrower ground that this particular search was reasonable in its purpose and scope.
“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 a broad ruling on privacy expectations in new communication technology.
How it got here: A federal trial court ruled for the city after a jury found the audit's purpose was work-related; the Ninth Circuit reversed, and the city sought Supreme Court review.
The Case in Depth
What happened
The City of Ontario, California issued pagers to its police SWAT team, including Sergeant Jeff Quon, so officers could communicate during emergencies. After Quon repeatedly exceeded his monthly text-message limit, the police chief ordered a review of two months of his messages to see whether the limit was too low. The review revealed many personal, non-work messages, some sexually explicit, sent to Quon's wife, a girlfriend, and a fellow officer, all of whom joined his lawsuit.
The question before the Court
Could a police department read text messages on a pager it issued to a SWAT officer, after finding he was running up overage fees on personal use?
The Court's answer
No — the City did not violate the Fourth Amendment. Even assuming Sergeant Quon had a reasonable expectation of privacy in his text messages, the Court found the police department's review of two months of transcripts was reasonable: it was ordered for a legitimate, work-related reason (checking whether the pager plan's character limit was adequate) rather than to pry into his personal life, and the review was limited in scope, covering only two months and excluding off-duty messages.
The Court also rejected the argument that the department had to use a less intrusive method, and held that the other people who exchanged texts with Quon could not succeed either, since their claims depended entirely on the search being unreasonable as to Quon himself.

Why it matters
Government employees who use employer-issued phones, pagers, or computers can have their communications reviewed when the employer has a legitimate work-related reason and keeps the search limited in scope. The ruling gives public employers a workable standard for auditing work devices without necessarily obtaining a warrant, while leaving broader questions about digital privacy for future cases.
What changes now
The case is sent back to the lower courts for further proceedings consistent with the ruling that the Fourth Amendment was not violated. This is a final decision on the merits of the constitutional claim, though it leaves broader questions about employee privacy in electronic communications unresolved for future cases involving new technology.
What this does not decide
The Court expressly avoided deciding whether public employees generally have a reasonable expectation of privacy in messages sent on employer-issued devices, or which analytical framework from O'Connor v. Ortega governs such claims. It resolved only that this particular search, even assuming privacy protections applied, was reasonable.
Concurrences and dissents
Concurrence — Justice Stevens
Justice Stevens agreed with the majority's decision not to resolve which O'Connor framework applies, and highlighted that Justice Blackmun's O'Connor dissent offered yet a third approach to assessing an employee's privacy expectations. He noted that under any of the three approaches from O'Connor, the result here would be the same because Quon, as a SWAT officer, should have known his on-duty communications could face scrutiny.
Concurrence in part — Justice Scalia
Justice Scalia joined the opinion except for Part III-A, criticizing the majority for discussing at length a threshold privacy question it admitted was unnecessary to decide. He argued that once the Court concluded the search was reasonable regardless of the applicable test, it should not have speculated about how emerging technology affects privacy expectations, calling the majority's caution 'indefensible.'
How the Court got there
The legal reasoning, step by step
- The Court assumed without deciding that Quon had a reasonable expectation of privacy in his text messages, avoiding the unsettled split from O'Connor v. Ortega (a 1987 case on analyzing government-employee privacy claims) between a four-Justice test based on 'operational realities' and Justice Scalia's simpler approach.
- Under the O'Connor plurality's framework, a warrantless workplace search is reasonable if it is justified when it begins and no broader in scope than needed to address the circumstances prompting it.
- The search was justified at its start because the police chief ordered it for a legitimate, non-investigative reason: checking whether the pager plan's monthly character limit was too low, not to pry into Quon's personal life.
- The scope of the search was reasonable because the department reviewed transcripts for only two months, and the internal-affairs officer redacted messages Quon sent while off duty, reducing the intrusion.
- The Court rejected the Ninth Circuit's view that the department had to use the least intrusive method available, explaining that the Fourth Amendment requires only a reasonable search, not the most minimal one imaginable.
- Because the search was reasonable as to Quon under either O'Connor approach, and the other respondents who exchanged texts with him offered no separate argument that the search could be unreasonable as to them even if reasonable as to him, none of the respondents could prevail.
