United States v. Microsoft Corp.

The case asked whether Microsoft had to produce emails stored on foreign servers in response to a U.S. warrant under the Stored Communications Act. After Congress passed the CLOUD Act and the government got a new warrant, the Supreme Court did not answer that question and instead wiped away the Second Circuit's ruling and sent the case back as moot.

In a per curiam opinion, the Court vacated the Second Circuit's judgment after the dispute became moot; no vote breakdown is provided here.

The fight mattered for email companies and investigators handling data stored overseas. For example, it affected whether a U.S. company could be forced to retrieve a customer's emails from a server in another country.

The case returned to the lower courts after the Supreme Court vacated the prior judgment as moot. Any future fights over overseas data would have to arise in new cases under the updated law.

The government wanted Microsoft to turn over emails under a U.S. warrant, even though Microsoft had stored the emails on servers abroad.

It affected other tech companies and users whose data is stored around the world. It also shaped how investigators seek digital evidence kept overseas.

The Court sent the case back after vacating the lower-court ruling as moot. The legal issue could return later in a different case under the CLOUD Act.
