United States v. Steven Duarte

Plain English (For Everyone)

The court ruled that if your phone isn't encrypted and police legally seize it, they can search the data on it without a warrant. This means information on your phone might not be as private as you think once it's in police custody.

For Legal Practitioners

The Ninth Circuit affirmed the denial of a motion to suppress, holding that a defendant lacks a reasonable expectation of privacy in unencrypted cell phone data post-seizure. This decision reinforces that the accessibility of data, rather than mere possession, is critical to Fourth Amendment analysis.

For Law Students

In United States v. Duarte, the Ninth Circuit held that unencrypted cell phone data on a lawfully seized device is not protected by a reasonable expectation of privacy under the Fourth Amendment, allowing for warrantless searches of such data.
