40 REASONABLE EXPECTIONS OF PRIVACY SETTINGS [Vol. 13
protections against unreasonable searches and seizures may not reach the
virtual world. First, Supreme Court privacy jurisprudence has created
“uncertainty over whether and when Internet users can retain a ‘reasonable
expectation of privacy’ in information sent to network providers, including
e-mails.”
In United States v. Miller, the Supreme Court established the
third-party doctrine, which denies Fourth Amendment protections to
information disclosed to an entity not originally party to the
communication.
Because virtually all Internet communications are shared
with a network service provider, i.e., a third party, users may be
categorically prohibited from enjoying a reasonable expectation of privacy
online. Second, Fourth Amendment rules governing grand jury subpoenas
suggest that the government may subpoena online communications held by
third-party network service providers without first obtaining a warrant
based on probable cause.
Third, most providers are private actors and
may therefore disclose stored communications without violating the Fourth
Amendment.
A. Legislative History of the SCA
In October 1985, the Office of Technology Assessment issued a
report entitled “Electronic Surveillance and Civil Liberties,” which
concluded that “current legal protections for electronic mail are weak,
ambiguous, or non-existent,” and that “electronic mail remains legally as
well as technically vulnerable to unauthorized surveillance.”
One year
later, Congress passed the Electronic Communications Privacy Act
(“ECPA”), and with it 18 U.S.C. §§ 2701–2712, or the SCA, “to update and
clarify Federal privacy protections and standards in light of dramatic
changes in new computer and telecommunications technologies.”
The
Senate Report on the SCA highlights Congress’s desire to extend to
electronic communications the underlying privacy protections already
afforded to postal mail and private telephone conversations:
A letter sent by first class mail is afforded a high level of protection
against unauthorized opening by a combination of constitutional
provisions, case law, and U.S. Postal Service statutes and regulations.
Voice communications transmitted via common carrier are protected
by title III of the Omnibus Crime Control and Safe Streets Act of
1968.
