Case Summary
COMMONWEALTH v. BRENDAN J. GARAFALO (And Nine Companion Cases), decided by Massachusetts Supreme Judicial Court on May 2, 2025, resulted in a mixed outcome. This case consolidated ten appeals concerning the admissibility of evidence obtained through the use of cell site location information (CSLI) without a warrant. The Supreme Judicial Court of Massachusetts held that the warrantless collection of CSLI violates the search and seizure provision of the Massachusetts Declaration of Rights, which provides greater protection than the Fourth Amendment. The court reversed the trial court's denial of the defendants' motions to suppress, requiring suppression of the CSLI evidence. The court held: The warrantless acquisition of cell site location information (CSLI) constitutes a search under the Massachusetts Declaration of Rights, because individuals have a reasonable expectation of privacy in their location data.. The Commonwealth failed to demonstrate that the warrantless collection of CSLI was justified by exigent circumstances, as there was no evidence of an immediate threat to public safety or the destruction of evidence.. The "third-party doctrine" does not apply to CSLI because the nature of cell phone technology and the continuous, pervasive tracking it enables create a different privacy interest than that associated with traditional third-party records.. The court rejected the argument that the "inevitable discovery" rule could justify the admission of the CSLI, as the Commonwealth did not show that the evidence would have been inevitably discovered through lawful means.. The defendants' motions to suppress the CSLI evidence should have been allowed, and the evidence obtained as a result of the warrantless searches must be suppressed.. This decision significantly strengthens privacy protections for electronic data in Massachusetts, establishing a higher bar for law enforcement to access CSLI than required by federal law. It signals that state courts may offer greater privacy rights than federal courts when interpreting their own constitutions in the face of technological advancements.

Deep Legal Analysis
Standard of Review
de novo review: The Supreme Judicial Court reviews questions of law, including constitutional interpretation, independently.
Procedural Posture
The case reached the Supreme Judicial Court of Massachusetts through consolidated appeals from trial court decisions denying defendants' motions to suppress evidence. The defendants were charged with various crimes, and the Commonwealth sought to use CSLI obtained without a warrant as evidence.
Burden of Proof
The Commonwealth bears the burden of proving that its warrantless search for CSLI was constitutional. The standard is whether the Commonwealth has demonstrated that the search was reasonable under the Massachusetts Declaration of Rights.
Legal Tests Applied
Reasonable Expectation of Privacy
Elements: A person must exhibit an actual (subjective) expectation of privacy. · The expectation must be one that society is prepared to recognize as 'reasonable' (objective).
The court held that individuals have a reasonable expectation of privacy in their historical CSLI, even though it is voluntarily conveyed to a third-party service provider. This expectation is objectively reasonable because individuals do not expect their movements to be continuously tracked and recorded by the government.
Search and Seizure Clause of the Massachusetts Declaration of Rights (Article 14)
Elements: Government intrusion into a constitutionally protected area. · Infringement upon a reasonable expectation of privacy.
The court found that the warrantless acquisition of CSLI constituted a search under Article 14 because it intruded upon individuals' reasonable expectation of privacy in their location data. This expectation is greater than that protected by the Fourth Amendment.
