The federal and state statutes that govern eavesdropping require interception of a conversation. The "interception" of a "private communication" is not merely listening to a private communication but includes the means used to "acquire" the "private communication". “Intercept” means to acquire the contents of any wire, electronic, or oral communication through the use of any electronic, mechanical, or other device. If the person is intercepting a private conversation, the federal law provides an exemption if done under the with the terms of a court order, statutory authorization, or certification under federal wiretapping law.
It may be possible to file criminal charges or file a civil lawsuit for invasion of privacy. Invasion of privacy is the intrusion into the personal life of another, without just cause, which can give the person whose privacy has been invaded a right to bring a lawsuit for damages against the person or entity that intruded. It encompasses workplace monitoring, Internet privacy, data collection, and other means of disseminating private information. A non-public individual has a right to privacy from: a) intrusion on one's solitude or into one's private affairs; b) public disclosure of embarrassing private information; c) publicity which puts him/her in a false light to the public; d) appropriation of one's name or picture for personal or commercial advantage.
Invasion of privacy may also include criminal charges, such as violation of wiretapping or criminal trespass statutes.
