High Quality Content by WIKIPEDIA articles! Ontario v. Quon, sometimes cited as City of Ontario v. Quon, 560 U.S. ___ (2010), is a United States Supreme Court case concerning the extent to which the right to privacy applies to electronic communications in a government workplace. It was an appeal by the city of Ontario, California, from a Ninth Circuit decision holding that it had violated the Fourth Amendment rights of two of its police officers when it disciplined them following an audit of pager text messages that discovered many of those messages were personal in nature, some sexually explicit. The Court unanimously held that the audit was work-related and thus did not violate the Fourth Amendment`s protections against unreasonable search and seizure.
