Carpenter v. United States in New York Law

How Carpenter v. United States applies in New York: state-specific rules, key cases, and bar exam notes for Criminal Procedure (Fourth Amendment).

State Approach

In New York, the Fourth Amendment principles established in Carpenter are adhered to strictly, emphasizing the need for a warrant when conducting searches that intrude upon a reasonable expectation of privacy. The state further enhances protection against unreasonable searches through its own Constitution.

State Rule
Under New York law, law enforcement must obtain a warrant supported by probable cause before accessing historical cell site location information (CSLI), aligning closely with the precedent set by Carpenter.
Significant State Cases

People v. Weaver

The court held that location data from a GPS device installed on a vehicle constituted a search under the New York Constitution, requiring a warrant.

In re Application for a Search Warrant for Historical Cell Site Data

This court ruled that the retrieval of historical CSLI necessitated a warrant, following Carpenter's reasoning regarding privacy expectations.

People v. Johnson

The court found that police access to cell phone records without a warrant violated the defendant's Fourth Amendment rights, highlighting the necessity of a warrant after Carpenter.

Comparison to Federal Law

New York's approach mirrors the federal standard established in Carpenter, reinforcing the necessity of a warrant for CSLI access. However, New York courts apply even stricter privacy protections under state law, which can lead to more extensive safeguards than federal precedents.

Bar Exam Note

Understanding the implications of Carpenter is essential for the New York bar exam, particularly in relation to Fourth Amendment jurisprudence and case law stemming from state constitutional protections.
