Why This Case Matters

Chatrie v. United States concerns geofence warrants: warrants that compel a technology company to search location-history data for devices that were near a particular place during a particular time.

The case matters because a geofence warrant can operate like a digital general warrant. Instead of identifying a suspect first and then seeking evidence, the government may begin with a location, compel a private database search across many users, and then work backward to identify a person.

For OLI, the case is important because objective law requires particularized limits on government searches. The Fourth Amendment is not only a procedural formality. It is a structural protection against exploratory rummaging through private life.

The legal question is whether the execution of a geofence warrant violates the Fourth Amendment.

The Supreme Court held that acquiring the location-history data was a search and vacated the lower court judgment, but remanded for further analysis. That means the issue remains active in the sense that the Court's decision does not finally resolve the reasonableness, particularity, suppression, and remedial questions.

The OLI Angle

An OLI analysis would emphasize that digital scale cannot be allowed to erase constitutional limits.

When government compels a company to search a massive store of private location data, the search should not be treated as harmless merely because the data sits with a third party. The relevant question is not whether the government physically entered a home. It is whether state power was used to invade a protected sphere of private life without objective, particularized justification.

Justice Gorsuch's property-and-contract approach is especially promising because it avoids relying entirely on elastic "reasonable expectation of privacy" doctrine. It asks whether users retain legal interests in data held by a service provider and whether government compulsion interferes with those interests.

What OLI Could Have Contributed

OLI could have helped frame geofence warrants as a modern form of the general-warrant problem.

The Fourth Amendment requires objective constraints: probable cause, particularity, and limits on discretion. A warrant that begins by searching many innocent people's location history risks reversing that structure. It identifies the target only after the search has already swept broadly through private data.

OLI could also help explain why property, contract, and objective rights analysis provide a more stable foundation than a purely sociological inquiry into expectations of privacy.

Why Timely Support Matters

Digital-search doctrine is developing quickly. Courts are deciding how old constitutional protections apply to databases, smartphones, location history, platform records, and compelled searches by private intermediaries.

OLI could add value by preparing principled analysis before the next major digital-search case reaches a decisive stage.

Clarification

OLI's concern is not opposition to legitimate criminal investigation or the use of digital evidence. The principle is that government may not evade Fourth Amendment limits by compelling broad searches of private databases without objective, particularized justification.
