Carolina Criminal Defense & DUI Lawyer UpdatesGoogle Location History now carries Fourth Amendment protection when police obtain it from Google during a criminal investigation. On June 29, 2026, the United States Supreme Court held in Chatrie v. United States that police conduct a search when they acquire historical cell phone location data from Google, even when the request covers only a limited time and even though Google keeps the records on its servers.
That does not make every digital location search unlawful. It does not mean the evidence in Chatrie must be suppressed. It does not prevent police from using location data to investigate serious crimes.
Key Point | Google Location History is not routine business paperwork simply because a technology company stores it. It can reveal where a phone traveled, where it stopped, and what private places it reached. When the government demands that information, the Fourth Amendment applies.
The holding is narrow, but important. For criminal defense lawyers, prosecutors, judges, and law enforcement, Chatrie answers the threshold question that had divided courts. Historical location data from Google is constitutionally protected. Once the police obtain that data, the case involves Fourth Amendment issues, including probable cause, particularity, the scope of the search, the manner in which the warrant was executed, and whether the good-faith exception applies.
Justice Kagan wrote the majority opinion, joined by Chief Justice Roberts and Justices Sotomayor, Kavanaugh, and Jackson. Justice Gorsuch concurred in the judgment, giving the Court a 6-to-3 result. Justice Jackson wrote separately, joined by Justice Sotomayor. Justice Alito dissented, joined in part by Justice Thomas and in part by Justice Barrett. Justice Barrett also filed a separate dissent.
For North Carolina criminal cases involving digital evidence, cell phone records, search warrants, robbery investigations, drug cases, firearm charges, impaired driving investigations, and homicide-by-vehicle charges, Chatrie is now part of the Fourth Amendment analysis. A warrant for digital location data is not judged only by whether the investigation was serious. Courts must also examine what the government requested, what the judicial official authorized, what Google produced, and how police used the information after they received it.
Geofence Warrants | Quick Reference Guide
| What to review | Why it matters |
|---|---|
| Whether police conducted a search | Police access to Google Location History data is now a Fourth Amendment search. The government cannot skip warrant analysis by calling the data voluntary third-party information. |
| Probable cause for the request | The warrant must show a fair probability that the location data sought holds evidence of the crime. A general hope of finding someone nearby may not be enough. |
| How specific the warrant is | The warrant must describe the search precisely enough to limit officer discretion. The geography, time window, data fields, and narrowing steps all matter. |
| Each step of a multi-step warrant | A geofence warrant can authorize several stages. Each stage may need its own probable cause, especially where officers choose targets without a judge’s review. |
| A short time window | A brief request can still invade protected privacy. Duration alone does not defeat Fourth Amendment protection. |
| Data held by Google | Storage on Google’s servers does not remove constitutional protection. Location History is treated differently from bank records or dialed phone numbers. |
| Whether officers relied on the warrant in good faith | Even with a flawed warrant, evidence may survive if officers reasonably relied on it. That question is left for further litigation. |
| What to gather in a North Carolina case | A careful review may include the affidavit, the data requested, the time and area covered, the narrowing language, judicial oversight, execution records, and the later use of identifying information. |
Geofence Warrants and the Fourth Amendment | What the Supreme Court Decided
A “geofence warrant” operates somewhat differently from traditional North Carolina search warrant law and suppression of evidence issues.
Police do not begin with a known suspect. They begin with a location and a time. The government draws a virtual boundary around a place, such as a bank, store, apartment complex, roadway, protest site, or crime scene. The warrant then directs a technology company to identify devices located inside that boundary during a set time window.
In Chatrie v. United States, the investigation began after a 2019 credit union robbery in Midlothian, Virginia. Officers learned that the alleged robber approached the credit union from a corner of an adjacent church while appearing to talk on a cell phone. They did not know who he was. Law enforcement sought a warrant requiring Google to provide Location History data for phones within a 150-meter radius of the credit union during the hour surrounding the robbery.
The warrant used a three-step process. At step one, Google produced anonymized location data for devices within the geofence from 30 minutes before the robbery to 30 minutes after it. At step two, officers narrowed the list and obtained additional anonymized location data for a two-hour window, both inside and outside the geofence. At step three, officers narrowed the list again and obtained identifying account information, including names, email addresses, and phone numbers.
That process identified Okello Chatrie. A federal grand jury charged him with robbery and firearm offenses. He moved to suppress the Google location evidence.
The Supreme Court did not decide whether the warrant was valid. It decided a more threshold question. When police obtained Chatrie’s Location History data from Google, they conducted a Fourth Amendment search.
The Catrie holding matters because the government argued that no search occurred at all. The U.S. Supreme Court rejects that position.
Google Location History | Not an Ordinary Business Record
The government relied heavily on the third-party doctrine. That doctrine comes from older cases involving bank records and dialed telephone numbers. The theory is simple. When you voluntarily give information to a third party, you assume the risk that the third party may hand it to law enforcement.
The Supreme Court refused to apply that doctrine mechanically to Google Location History.
The Court’s reasoning follows Carpenter v. United States, the 2018 case involving cell-site location information. In Carpenter, the U.S. Supreme Court held that police generally need a warrant to obtain historical cell-site records in that such records reveal a detailed account of the defendant’s physical movements.
Chatrie extends that reasoning to Google Location History. In some ways, Location History reveals more than the cell-site data at issue in Carpenter. The Court noted that Location History may record a phone’s location every two minutes, may place a phone within roughly 20 meters, and may estimate elevation, which can reveal the floor of a building where a phone sits.
That level of detail changes the constitutional analysis.
A bank record may show a transaction. A dialed phone number may show that a call occurred. Location History can show where a phone traveled, where it paused, whether it entered a medical building, whether it attended a political event, whether it went home, and whether it moved from the alleged crime scene to another location.
The Supreme Court also rejected the idea that Location History loses protection because Google stores the data. Modern life depends on cloud storage. Emails, photographs, calendars, documents, and maps may reside on company servers even as users still reasonably regard them as private.
That reasoning speaks directly to criminal charges in the digital age. A constitutional rule built for paper files and landline phones cannot be applied blindly to databases that can reconstruct movement through public and private spaces.
Search and Seizure Law | Timing & Extent of Search
The government in Chatrie argued the data request was too short to count as a search. Carpenter held that accessing seven days of cell-site records is a search. The geofence request in Chatrie covered a shorter period of time.
The Supreme Court rejected a rigid time threshold.
Short-term location tracking can reveal private information. A two-hour window may show attendance at a political rally, a medical appointment, a religious service, a meeting with a criminal defense lawyer, a school, a hospital, or a private residence. The Court refused to make Fourth Amendment protection depend on whether the government collected enough data to render the intrusion onerous.
That part of Chatrie may become one of the more contested features of the opinion. Justice Alito’s dissent argues that Carpenter should remain limited to longer-term location tracking and should not control a short geofence request tied to a public bank robbery investigation. The majority took a different view. For cell phone location data, the constitutional injury does not disappear because the government requested a shorter period of time, sufficient to prove temporal proximity for the crime.
For trial lawyers, that is clearly important. The first question is no longer whether 2 hours, 1 hour, or 30 minutes are enough. After Chatrie, police access to historical cell phone location data from Google is in fact a search subject to the confines of the Fourth Amendment. The litigation addresses probable cause, particularity, scope, execution, and any alleged good-faith exception to the warrant requirement.
What the Supreme Court Did Not Decide About Geofence Warrants
Chatrie is powerful, but it is not a complete roadmap for suppression.
The Supreme Court did not hold that all geofence warrants are unconstitutional. It did not hold that the evidence against Chatrie must be suppressed. It did not decide whether a good-faith exception to the exclusionary rule permits the government to use evidence despite defects in a bad search-warrant affidavit in North Carolina.
Instead, the U.S. Supreme Court vacated the Fourth Circuit’s judgment and remanded the case. The Fourth Circuit must now decide whether the warrant satisfied the Fourth Amendment at each stage of the search process.
That remand matters because the warrant had unusual features. The first step captured anonymized data from devices inside the geofence. The second step allowed officers to obtain more data for selected devices over a broader time window. The third step let officers obtain identifying account information.
The Court questioned how little the warrant said about the narrowing process. It left to the Fourth Circuit to determine whether the warrant provided sufficient guidance at each stage and whether probable cause supported each stage. The Court also left room for recognized exceptions to the warrant requirement. A footnote preserves the possibility of a warrantless geofence search when exigent circumstances make it reasonable.
Justice Jackson would have gone further. In her concurrence, she wrote that steps two and three lacked adequate judicial oversight because the warrant set no clear criteria for narrowing the device list. In her view, officers were given too much discretion in deciding which additional data and identifying information to obtain. She pointed out that the second-stage data exposed trips to private residences, a school, and a hospital.
That concurrence provides a litigation roadmap, even though it did not command a majority.
The Property-Based Theory in Justice Gorsuch’s Concurrence
Justice Gorsuch agreed that the government conducted a search, but he did not rely on a reasonable-expectation-of-privacy analysis or standing to challenge a search.
His view rested on the text of the Fourth Amendment, which protects persons, houses, papers, and effects. He treated Location History as a form of personal property, or a digital effect. The fact that Google stored the data did not end the inquiry. Everyday citizens regularly entrust property to others for limited purposes without giving up every constitutional protection in that property. He compared the arrangement to handing car keys to a valet or asking a neighbor to watch a dog.
That concurrence is interesting in that it suggests a future path for Fourth Amendment litigation involving digital records. Rather than forcing modern privacy questions into the third-party doctrine, courts may ask whether digital data functions like a paper, an effect, a diary, a map, or a personal record.
For defense lawyers challenging digital searches, that theory may become useful in cases involving cloud storage, app data, photographs, calendars, search history, vehicle telematics, wearable devices, smart-home records, and other digital records stored outside the physical phone.
Geofence warrant litigation after Chatrie will likely focus less on whether the Fourth Amendment applies and more on how carefully the warrant was written and executed.
What Chatrie Means for North Carolina Criminal Defense
North Carolina criminal defense regularly involves consideration of the underlying fact pattern when police use geofence warrants, reverse-location warrants, Google Location History, tower dumps, app-based location data, or similar digital search methods.
The practical question is not necessarily whether geofence data appears useful to law enforcement. It plainly can be useful, if not time-saving, easier to perform, and dispositive in nature. The constitutional question, vis-à-vis the Fourth Amendment, is whether the government obtained personal information and datum through a lawful process.
A review of a North Carolina Search Warrant and Application for Search Warrant forms may include the facts supporting probable cause, the place or database to be searched, the items or data to be seized, the time period covered, the geographic boundaries, and the instructions given to the technology company. In a geofence case, the narrowing process deserves close attention. A warrant that allows officers to decide later which data deserves deeper review may raise serious particularity concerns.
That is both consistent with Article 11, Search Warrants of Chapter 15A, as well as the North Carolina State Constitution, Article I, Section 20, regarding General Warrants. Indeed, the NC State Constitution adds interesting cautionary language, setting forth that General Warrants, “. . .[a]re dangerous to liberty and shall not be granted.”
The defense may likely want to review discovery showing how the warrant was executed. The written warrant may say one thing. The messages between law enforcement and the technology company may show another. Google may have required narrowing. Officers may have requested more data than the warrant justified. The final identification step may have rested on criteria no independent judicial official approved.
That is important because digital searches can expand quietly. A search that begins as a small circle on a map can become a broader inquiry into movement before and after the alleged offense. A request for anonymized data can become a request for names, phone numbers, email addresses, and account details. A search focused on a crime scene can expose residences, schools, medical facilities, religious spaces, and unrelated travel.
Chatrie gives lawyers and courts the vocabulary to address those problems somewhat more directly.
Geofence Warrants | Google’s Location History Change
The Supreme Court noted that Google changed how it stores Location History in July 2025. According to Google, Location History data now sits on users’ devices rather than on Google’s servers, and Google says it can no longer respond to geofence warrants seeking that data.
That does not make Chatrie irrelevant or make the issue otherwise moot.
First, older cases may still involve historical Google responses from before the storage change. Second, other companies may store location data in different ways. Third, law enforcement may seek similar information from apps, vehicles, advertising databases, phones, cloud backups, mapping services, ride-share platforms, or other digital sources. Fourth, courts will still need to decide how Fourth Amendment principles apply when the government uses technology to identify who was present at a location.
The constitutional lesson remains. Location data can reveal private movement. When the government demands that data, the Fourth Amendment may require a warrant supported by probable cause and limited with particularity.
Geofence Warrants and Location History | FAQs
Are geofence warrants legal?
Chatrie v. United States did not ban geofence warrants. The U.S. Supreme Court held that obtaining Google Location History data through a geofence warrant is a Fourth Amendment search. The Court left open whether the warrant in Chatrie’s case satisfied the probable cause and particularity requirements.
Is evidence obtained through a Geofence Warrant admissible?
Geofence evidence after Chatrie still depends on the warrant, the facts, the scope of the search, the execution of the search, and any alleged good-faith exception to the warrant requirement. U.S. Supreme Court case law as of June 2026 indicates a Fourth Amendment search occurs relative to that type of personal information. Suppression of potentially illegally obtained evidence requires additional legal analysis.
Is Google Location History private?
Google Location History can create a detailed record of movement, including location, time, travel path, and sometimes elevation. The U.S. Supreme Court views such information as meaningfully different from ordinary business records because it can reveal private patterns, sensitive locations, and personal movement.
Does the "third-party doctrine" protect cell phone location information?
The third-party doctrine still exists, but Chatrie v. United States (June 2026 U.S. Supreme Court Opinion) limits its use in cell phone location cases. The Supreme Court has ruled that a defendant does not lose Fourth Amendment protection because Google stores Location History data on its servers.
Does the amount of time matter with a search?
In the context of a Geofence Search and Google Location History inquiry, a short period of location data can reveal a surprising amount of sensitive information. A two-hour window may show travel to a medical office, a residence, a school, a religious site, a political event, or a lawyer’s office. The U.S. Supreme Court specifically rejected a rule that would make privacy protection depend only on duration.
What is required for a geofence warrant?
A geofence warrant is subject to Fourth Amendment protections and is predicated on a finding of probable cause and describes the search with particularity. That means the warrant should identify the location, the time window, the data requested, the narrowing process, and the identification process with enough precision to limit officer discretion.
Why did Justice Jackson write separately in Chatrie?
Justice Jackson agreed that a search occurred, but she would have held the warrant unconstitutional at least as to its later stages. She focused on the missing criteria for narrowing the device list before officers obtained more data and identifying account information.
Why did Justice Gorsuch agree with the result in Chatrie?
Justice Gorsuch agreed that the government conducted a search, but he relied on a property-based theory. He treated Location History as a digital effect or personal record protected by the Fourth Amendment, even though Google stored it.
Why did the dissent disagree in Chatrie?
The dissenters viewed the data request as short, tied to a public location, and based on information disclosed to Google. Justice Alito argued that the Court should not have reached the question, because its ruling does not change the outcome for Chatrie given the unreviewed good-faith holding. He warned that the majority extended Carpenter beyond its stated limits, creating uncertainty for other digital records.
Does Chatrie matter in North Carolina criminal cases?
North Carolina criminal cases involving geofence warrants, cell phone location records, app data, or digital movement evidence call for review of probable cause, particularity, scope, execution, and good faith. The decision gives trial courts a U.S. Supreme Court framework for analyzing location-data searches.
Digital Search Warrants | North Carolina Criminal Charges
Chatrie v. United States is not a defendant-wins-everything ruling. It is a Fourth Amendment opinion about how courts should treat powerful location technology.
The U.S. Supreme Court recognizes a practical reality. Cell phones are not just communication devices. They are maps, cameras, calendars, notebooks, wallets, health monitors, and location trackers. When the government uses a phone’s location history to identify who was near a crime scene, it relies on technology that can reveal far more than physical presence alone.
For law enforcement, Chatrie does not close the investigative path. It calls for better warrants. For prosecutors, it means geofence evidence may need a more careful foundation. For trial judges, it presents hard questions about probable cause and particularity at each stage of a digital search. For defense lawyers, it confirms that location data is not ordinary paperwork because a technology company stores it.
If your case involves a search warrant, cell phone evidence, geofence data, or digital location records, a careful review can make a meaningful difference.
