S18G1546. MOBLEY v. THE STATE.

BLACKWELL, Justice.

After he was tried and convicted of two vehicular homicides, Victor Mobley appealed, claiming that the trial court erred when it denied his pretrial motion to suppress evidence of data that law enforcement officers retrieved without a warrant from an electronic data recording device on his vehicle. In denying the motion to suppress, the trial court had concluded that, whether or not the retrieval of the data was an unlawful search and seizure, the evidence was admissible in any event under the inevitable discovery doctrine. In Mobley v. State, 346 Ga. App. 641 (816 SE2d 769) (2018), a three-judge panel of the Court of Appeals affirmed, one judge reasoning that the retrieval of data was not a search and seizure at all, and two judges agreeing with the trial court that the inevitable discovery doctrine applied. We issued a writ of certiorari to review the decision of the Court of Appeals, and for the reasons

that follow, we conclude that the trial court erred when it denied the motion to suppress. The judgment of the Court of Appeals, therefore, is reversed.

1. On the afternoon of December 15, 2014, Mobley was driving a 2014 Dodge Charger on Flippen Road in Henry County. A 1999 Chevrolet Corvette pulled onto Flippen Road from a private driveway, and the Charger collided with it. Mobley survived the crash, but the two occupants of the Corvette did not. At first, the law enforcement officers who responded to the scene of the collision found no indication that Mobley had been driving too fast. Indeed, based on their preliminary assessment of the scene and their initial discussions with witnesses, the officers thought it likely that the driver of the Corvette had caused the collision simply by driving into the path of the Charger.

But before the vehicles were removed from the scene of the collision, Sergeant David Gagnon — a supervisor in the Traffic Division of the Henry County Police Department — directed officers to retrieve any available data from the airbag control modules

(ACM) on the Charger and Corvette.1 Investigator Jason Hatcher entered the passenger compartments of both vehicles, attached a crash data retrieval (CDR) device to data ports in the cars, and used the CDR to download data from the ACMs. The data retrieved from the Charger indicated that, moments before the collision, Mobley was driving nearly 100 miles per hour. The officers subsequently cleared the scene and had the Charger and Corvette both towed to an impound lot for further investigation.

1 The record shows that an ACM, also known as an “event data recorder”

or “electronic control module,” is an onboard electronic data recording device that is designed to preserve certain data about the operation of a vehicle in the moments preceding certain occurrences, including any event that results in the deployment of airbags. Although the precise data preserved varies from vehicle to vehicle, the data retrieved from the Charger in this case included the speed of the vehicle, the status of the brakes, the status of the brake switch, the time from maximum deceleration to impact, the time from impact to airbag deployment, the speed of the engine, the throttle position, the number of crankshaft revolutions per minute, the status of the driver’s seatbelt, and a diagnostic indicator about the functioning of the ACM.

The record in this case also shows that the data recorded by an ACM upon the happening of some occurrences subsequently may be overwritten, but the data is permanently recorded — and cannot be overwritten — when the precipitating event is an airbag deployment. The collision on December 15, 2014, resulted in the deployment of airbags in both the Charger and the Corvette.

The next day, Investigator Bryan Thornton joined the team of officers investigating the collision.2 He discussed the case with the officers who had responded to the crash, visited and personally inspected the scene of the collision, and then applied for a warrant to search the Charger and Corvette and to physically remove and seize the ACMs from both vehicles. When Investigator Thornton made his application for a warrant, he was aware that Investigator Hatcher already had retrieved the data from the ACMs and that the data indicated that the Charger had been traveling at an excessive rate of speed.3 His application, however, did not rely on the data to establish probable cause for the seizure of the ACMs. A magistrate

2 Investigator Thornton was off duty on the day of the collision.

3 At the hearing on the motion to suppress, Investigator Thornton testified that he was aware that data already had been retrieved at the scene of the collision. And although he did not testify explicitly about his knowledge of the substance of that data at the time he applied for a warrant, he said that the data was the basis for the conclusion that Mobley committed vehicular homicide in the first degree (as opposed to some lesser offense or no offense at all). In the warrant application, Investigator Thornton represented that the ACMs likely contained evidence of vehicular homicide in the first degree. His testimony at the hearing implies, therefore, that he had a meaningful awareness of the substance of the data when he made the warrant application.

issued the warrant, officers executed the warrant at the impound lot, and the ACMs were removed from both vehicles. It appears, however, that no additional data was retrieved from the ACMs subsequent to the execution of the warrant.4 In June 2015, a Henry County grand jury indicted Mobley, charging him with two counts of vehicular homicide in the first degree, reckless driving, and speeding. Mobley later filed a motion pursuant to OCGA § 17-5-30 to suppress the evidence of the data retrieved without a warrant from the ACM in his Charger, alleging that the retrieval of data was an unreasonable search and seizure forbidden by the Fourth Amendment.5 The trial court held an

4 The warrant authorized the seizure of the ACMs but did not explicitly authorize any retrieval of data from the ACMs.

5 Mobley also alleged that the retrieval of data was an unlawful search

and seizure under Article I, Section I, Paragraph XIII of the Georgia Constitution of 1983. There are cases suggesting, however, that Paragraph XIII is coextensive with the Fourth Amendment and provides no greater protection against unreasonable searches and seizures. See, e.g., Wells v. State, 180 Ga. App. 133, 134 (2) (348 SE2d 681) (1986). Whether or not those cases are right, see Elliott v. State, 305 Ga. 179, 187-188 (II) (C) (824 SE2d 265) (2019), Mobley has made no argument based on constitutional text, context, or history that Paragraph XIII offers greater protection than the Fourth Amendment. Cf. Grady v. Unified Govt. of Athens-Clarke County, 289

evidentiary hearing on the motion in June 2017, and at that hearing, the prosecuting attorney presented the testimony of Sergeant Gagnon, Investigator Hatcher, and Investigator Thornton.

Following the presentation of evidence, the prosecuting attorney argued that the motion to suppress should be denied for several reasons. More specifically, she argued that:

 Mobley had no reasonable expectation of privacy with respect to the data, and for that reason, the retrieval of that data was not a search and seizure for purposes of the Fourth Amendment;

 Even if the retrieval of the data was a search and seizure, a warrant was unnecessary because the search was directed to an automobile;

 Exigent circumstances — namely, the possibility that the data could be lost or corrupted when the vehicles were towed away from the scene — permitted a warrantless search;

 Investigator Hatcher retrieved the data without a warrant in good faith reliance on his understanding that no warrant is required to retrieve data from an ACM at the scene of a serious crash; and
