Why This Case Matters

On June 29, 2026, the Supreme Court held that the government's acquisition of location-history information through the geofence process in Chatrie constituted a Fourth Amendment search. The Court vacated the judgment below and remanded rather than resolving every question about the warrant's constitutionality or the appropriate remedy.

The case is now back in the Fourth Circuit, where remand briefing is addressing the consequences of the Supreme Court's ruling.

For OLI, Chatrie presents the modern equivalent of a foundational Fourth Amendment problem: whether government may compel a private company to search a vast body of location information in order to identify people first and establish individualized suspicion afterward.

The Supreme Court resolved the threshold question that the acquisition of the location-history data was a search. The remand leaves further questions concerning the warrant's reasonableness, particularity, its resemblance to a prohibited general warrant, and the consequences of any constitutional violation.

The case also leaves room for deeper analysis of whether property and contract principles can provide a more objective foundation for digital privacy than an inquiry resting entirely on changing social expectations.

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.
