	Introduction

This is an outline of the Electronic Communications Privacy Act (ECPA). It also outlaws such installation or use except for law enforcement and foreign intelligence investigations. Each of these cases focused upon whether a warrantless trespass onto private property had occurred, that is, whether the means of conducting a search and seizure had been so unreasonable as to offend the Fourth Amendment. The FISA provides a procedure for judicial review and authorization of electronic surveillance and other forms of information gathering for foreign intelligence purposes. Two other Supreme Court cases influenced the development of federal law in the area. Congress has adjusted the components of ECPA and FISA, over the years. Title III: Prohibitions

In Title III, ECPA begins the proposition that unless provided otherwise, it is a federal crime to engage in wiretapping or electronic eavesdropping; to possess wiretapping or electronic eavesdropping equipment; to use or disclose information obtained through illegal wiretapping or electronic eavesdropping; or to disclose information secured through court-ordered wiretapping or electronic eavesdropping, in order to obstruct justice. It is a federal crime to disclose, with an intent to obstruct criminal justice, any information derived from lawful police wiretapping or electronic eavesdropping, i.e . Law Enforcement Wiretapping and Electronic Eavesdropping

Title III exempts federal and state law enforcement officials from its prohibitions on the interception of wire, oral, and electronic communications under three circumstances: (1) pursuant to or in anticipation of a court order, (2) with the consent of one of the parties to the communication; and (3) with respect to the communications of an intruder within an electronic communications system. Title III: Consequences of a Violation

		Criminal Penalties

Interception, use, or disclosure in violation of Title III is generally punishable by imprisonment for not more than five years and/or a fine of not more than $250,000 for individuals and not more than $500,000 for organizations. Civil Liability of the United States

The USA PATRIOT Act authorizes a cause of action against the United States for willful violations of Title III, the Foreign Intelligence Surveillance Act or the provisions governing stored communications in 18 U.S.C. Electronic Communications Privacy Act (Text). Counterintelligence access to telephone toll and transactional records. As used in this chapter—

(iv) is acting on a request for foreign assistance pursuant to section 3512 of this title; or

(3) the term "pen register" means a device or process which records or decodes or other dialing, routing, addressing, and signaling information reasonably likely to identify the source of a wire or electronic communication, provided, however, that such information shall not include the contents of any communication, but such term does not include any device or process used by a provider or customer of a wire or electronic communication service for billing, or recording as an incident to billing, for communications services provided by such provider or any device or process used by a provider or customer of a wire communication service for cost accounting or other like purposes in the ordinary course of its business;
(4) the term "trap and trace device" means a device or process which captures the incoming electronic or other impulses which identify the originating number or other dialing, routing, addressing, and signaling information reasonably likely to identify the source of a wire or electronic communication, provided, however, that such information shall not include the contents of any communication;

(6) the term "State" means a State, the District of Columbia, Puerto Rico, and any other possession or territory of the United States.
This report provides an overview of federal law governing wiretapping and electronic eavesdropping under the Electronic Communications Privacy Act (ECPA). It also appends citations to state law in the area and the text of ECPA.
It is a federal crime to wiretap or to use a machine to capture the communications of others without court approval, unless one of the parties has given his prior consent. It is likewise a federal crime to use or disclose any information acquired by illegal wiretapping or electronic eavesdropping. Violations can result in imprisonment for not more than five years; fines up to $250,000 (up to $500,000 for organizations); civil liability for damages, attorneys' fees and possibly punitive damages; disciplinary action against any attorneys involved; and suppression of any derivative evidence. Congress has created separate, but comparable, protective schemes for electronic communications (e.g., email) and against the surreptitious use of telephone call monitoring practices such as pen registers and trap and trace devices.
Each of these protective schemes comes with a procedural mechanism to afford limited law enforcement access to private communications and communications records under conditions consistent with the dictates of the Fourth Amendment. The government has been given narrowly confined authority to engage in electronic surveillance, conduct physical searches, and install and use pen registers and trap and trace devices for law enforcement purposes under ECPA and for purposes of foreign intelligence gathering under the Foreign Intelligence Surveillance Act.
