Taking Geofence Location Data Is a Search

On June 29, 2026, the Supreme Court held that police conducted a Fourth Amendment search when they obtained Okello Chatrie’s Google “Location History” data through a geofence warrant, because an individual has a reasonable expectation of privacy in records of his cell phone’s location. The Court vacated the judgment of the Fourth Circuit and remanded the case.1

The ruling matters because prosecutors can no longer start by arguing that this kind of geofence demand falls outside the Fourth Amendment. The next fights are about whether the warrant was valid and what happens if it was not. The Court decided one question and only that question: whether acquiring the data was a search. It had granted review limited to that issue, and it expressly declined to decide whether the warrant was valid or whether the evidence must be suppressed.3 Those questions now return to the Fourth Circuit.11

 
May 20, 2019

A man robbed the Call Federal Credit Union in Midlothian, Virginia, taking about $195,000 at gunpoint. Witnesses and surveillance showed that the robber had approached from a corner of an adjacent church while appearing to talk on a cell phone, but officers could not identify him.4

June 14, 2019

Roughly three weeks after the robbery, a detective applied to a Virginia magistrate for a geofence warrant directed to Google. The application described Location History—the Google service that records a phone’s location every two minutes or so—and drew a geofence with a 150-meter radius around the credit union.5

The Three Steps

Step one: Google produces anonymized location data for all phones in the geofence, 30 minutes before to 30 minutes after the robbery. Step two: officers narrow the list and Google adds data over a two-hour window, inside and outside the geofence. Step three: Google turns over identifying information. The process produced three users, including Chatrie.6

March 3, 2022

The District Court (Judge M. Hannah Lauck) concluded that “this particular geofence warrant plainly violates the rights enshrined in [the Fourth] Amendment,” but it still denied Chatrie’s motion to suppress. The officers had relied on the warrant in good faith, the court held, so the Leon good-faith exception let the evidence in.7

Good-Faith Exception

Under United States v. Leon, evidence from a flawed warrant may still be admitted if officers relied on it in objective good faith. That ruling—not any finding that the warrant was valid—is why Chatrie lost below.7

May–Aug. 2022

Chatrie pleaded guilty conditionally under Rule 11(a)(2), preserving his right to appeal the suppression ruling, and was sentenced to 141 months in prison. He appealed the judgment and the suppression decision to the Fourth Circuit.8

July 9, 2024

A divided Fourth Circuit panel affirmed, but on different reasoning: it held that no search had occurred because Chatrie “did not have a reasonable expectation of privacy in two hours’ worth of Location History data voluntarily exposed to Google.” Judge Wynn dissented.9

Panel: No Search

Because it found no search, the panel never reached the warrant’s validity. It decided the threshold question—whether the Fourth Amendment applied at all—against Chatrie.9

April 30, 2025

On rehearing en banc, the Fourth Circuit affirmed in a one-sentence per curiam: “The judgment of the district court is AFFIRMED.” The court split evenly, 7 to 7, on whether a search had occurred, and most judges who thought one had nonetheless applied the good-faith exception.10

Evenly Divided

Fifteen judges produced numerous separate writings; only Judge Gregory dissented from the judgment. The even split on the search question left the law unsettled—and set up Supreme Court review.10

Jan.–Apr. 2026

On January 16, 2026, the Supreme Court granted certiorari limited to Question 1—whether the geofence search violated the Fourth Amendment—and declined to take up the separate exclusionary-rule question. The Court heard argument on April 27, 2026.3

June 29, 2026

The Court held that the police conducted a Fourth Amendment search when they acquired Chatrie’s Location History data, reasoning that everything that made cell-site data a search in Carpenter v. United States “applies as well or better” to Location History, which is more precise, more comprehensive, and more the user’s own. It rejected the Government’s arguments that a short window of data is too little to count and that the third-party doctrine strips away any privacy interest.1 For police nationwide, the threshold question is now settled: obtaining this kind of location data is a search that needs a warrant—though what a valid geofence warrant must contain is left undecided.11

What the Court Left Open

The Court did not decide whether the warrant was valid. Whether each step met probable cause and particularity—and whether the good-faith exception still lets the evidence in—is for the Fourth Circuit on remand. This is “a court of review, not of first view.”11

June 29, 2026

Justice Kagan wrote for the Court, joined by the Chief Justice and Justices Sotomayor, Kavanaugh, and Jackson.2 Justice Jackson, joined by Justice Sotomayor, concurred and would have gone further, calling the warrant’s second and third steps a “roving commission” that lacked probable cause and particularity.12

The Line-Up

Justice Gorsuch concurred only in the judgment, finding a search by a property-based route while rejecting the Katz “reasonable expectation” test and the third-party doctrine.13 Justice Alito, joined in part by Justices Thomas and Barrett, dissented and called the decision “advisory”; Justice Barrett also dissented separately.14

 
Current Record
Through June 29, 2026

This is one decision in one case. The Supreme Court held only that acquiring Location History data through this geofence process was a Fourth Amendment search. It did not decide whether the warrant was valid, whether probable cause or particularity were satisfied at any step, whether the good-faith exception still applies, or whether Chatrie’s convictions stand—all of which return to the Fourth Circuit.11 Separately, the Court noted that in July 2025 Google began storing Location History on users’ own devices and represents that it can no longer respond to geofence warrants seeking that data.15

Detective Hylton applied for the geofence warrant on June 14, 2019, “roughly three weeks after the robbery” (ECF 220, PDF p. 24); the warrant drew a 150-meter-radius geofence (300-meter diameter) (ECF 220, PDF p. 25). Location History records a phone’s location “every two minutes or so” and is “the most sweeping, granular, and comprehensive tool” for storing such data (ECF 220, PDF p. 5, 590 F. Supp. 3d 901, 907; slip op., PDF pp. 3, 6).

The three-step process: step one, anonymized data for all phones in the geofence 30 minutes before to 30 minutes after the robbery; step two, a narrowed list with additional anonymized data over a two-hour period inside and outside the geofence; step three, identifying information for users on the final list. Google ultimately produced three users’ identifying information, including Chatrie (slip op., syllabus, pp. 1–2; warrant’s narrowing language quoted by the Court at “2 App. 136–137”).

“[T]his particular geofence warrant plainly violates the rights enshrined in [the Fourth] Amendment” (ECF 220, PDF p. 2; 590 F. Supp. 3d 901, 905). The court denied suppression under the Leon good-faith exception because the officers “sought the warrant in good faith” (ECF 220, PDF p. 35; final holding PDF p. 63; 590 F. Supp. 3d 901, 937–938; United States v. Leon, 468 U. S. 897 (1984)). ECF 221 is the one-page order that formally denies the motion and points back to the accompanying memorandum opinion.

“The defendant agrees that he is pleading guilty conditionally” and, under Rule 11(a)(2), “preserves his right to appeal the District Court’s” suppression ruling (ECF 228, PDF p. 5). Sentenced Aug. 10, 2022 to 57 months (Count 1) plus 84 months consecutive (Count 2) — 141 months — with $196,932.01 restitution (docket entries 238, 239). Notice of appeal filed Aug. 25, 2022 as to the judgment (ECF 239), the memorandum opinion (ECF 220), and the suppression order (ECF 221); docketed as Fourth Circuit No. 22-4489 (ECF 241; docket).

9. Sources: Panel opinion, 107 F. 4th 319 (PDF pp. 1, 10)|Slip op., PDF p. 14 (Doc 119)
Panel (Wilkinson and Richardson, JJ.) affirmed July 9, 2024, holding Chatrie “did not have a reasonable expectation of privacy in two hours’ worth of Location History data voluntarily exposed to Google. So the government did not conduct a search” (PDF p. 10; 107 F. 4th 319, 325). Judge Wynn dissented (panel header, PDF p. 1; slip op., PDF p. 14).

10. Sources: En banc opinion, 136 F. 4th 100 (PDF pp. 1–4)|Slip op., PDF p. 14 (Doc 119)
En banc Fourth Circuit affirmed April 30, 2025 in a one-sentence per curiam: “The judgment of the district court is AFFIRMED” (PDF p. 4; 136 F. 4th 100, 101). Fifteen judges sat; only Judge Gregory dissented from the judgment (lineup, PDF p. 2). The Supreme Court characterized the court as “divided evenly (7 to 7) on whether a Fourth Amendment search had occurred,” with most who found a search applying the good-faith exception (slip op., PDF p. 14).

11. Source: Slip op., opinion of the Court (Doc 119, PDF pp. 34–37; p. 15 n. 4)
The Court left to the Fourth Circuit “whether, at each step of the search process, the warrant satisfied the Fourth Amendment’s requirements of particularity and probable cause,” being “a court of review, not of first view” (printed pp. 29–32; PDF pp. 34–37). It expressly did “not address whether the good-faith exception to the exclusionary rule still allows the admission of the Location History data” (p. 15 n. 4).

12. Source: Slip op., Jackson, J., concurring (Doc 119, PDF pp. 39–41)
Jackson, J., joined by Sotomayor, J., concurring: would hold the search violated the Fourth Amendment because, “at a minimum,” steps two and three lacked probable cause and particularity, giving officers a “roving commission” outside magisterial supervision; urges the Fourth Circuit to keep that in mind on remand (PDF pp. 39–41).

13. Source: Slip op., Gorsuch, J., concurring in the judgment (Doc 119, PDF pp. 42–50)
Gorsuch, J., concurring in the judgment: agrees the examination of Location History was a search, but would reach that result on a property / positive-law route rather than the Katz “reasonable expectation of privacy” test, which he would discard along with the third-party doctrine (PDF pp. 42–50).

14. Sources: Slip op., Alito, J., dissenting (Doc 119, PDF pp. 51–71)|Barrett, J., dissenting (PDF p. 72)
Alito, J., dissenting (joined by Thomas, J., as to Part I, and by Barrett, J., as to Parts II–B, II–C–1, II–C–2): would have dismissed or affirmed on the good-faith exception and calls the majority an “advisory opinion” on a “now-obsolete” procedure that “will [not] affect the outcome of this case” (PDF pp. 51–54). Barrett, J., dissenting: under existing precedent, including Carpenter, Chatrie had no reasonable expectation of privacy in public-movement data voluntarily disclosed to Google (PDF p. 72).

15. Sources: Slip op., p. 4 n. 2 (Doc 119, PDF p. 9)|Google, “Updates to Location History,” Dec. 12, 2023
The Court noted that “in July 2025 … Google made a change: It now stores Location History data on individual users’ devices rather than on its own servers,” and “represents that, as a result, it is no longer capable of responding to geofence warrants that seek Location History data” (slip op., p. 4 n. 2; PDF p. 9). Google’s Dec. 12, 2023 announcement (“Timeline will soon be saved on your device”) is the background to that change.
