Washington has a civil anti-harassment statute to protect against repeated invasions of a person's privacy. One form of “intrusion” is electronic eavesdropping, which is specifically governed by RCW 9.73. 030-. 250 of the Washington Privacy Act.
Intrusion into Seclusion
Intrusion upon seclusion is what people commonly think of as “invasion of privacy.” Intrusion upon seclusion occurs when someone intentionally intrudes into the private affairs of another person. The legal standard for intrusion upon seclusion requires that the intrusion be intentional and highly offensive to a reasonable person.[2]
Intrusion into Seclusion
The most straightforward case is when the victim is in a private location, such as a private home or hotel room. If an intruder infringes on these areas by planting a camera, peeping or otherwise violating the privacy of the area, that is a form of invasion of privacy.[3] Another area where intrusion into seclusion has been litigated is in the work place. Although people in a work setting are aware that others may hear what they discuss, there is an expectation that discussions among colleagues at work will not be surreptitiously recorded. So, the use of secret electronic surveillance can be considered an intrusion into seclusion under normal circumstances.[4]
