Gant's Two-Prong Test
Search incident to lawful arrest
Gant's Two-Prong Test
The automatic compartment search that Belton allowed rested on a generalization about what an arrestee can reach, and Arizona v. Gant tested that generalization on facts where it failed. An earlier records check had shown that Rodney Gant's license was suspended and that a warrant was outstanding for driving with a suspended license.1 When Tucson officers returned that evening to a house an anonymous tip had identified as a drug-sale location, Gant drove up, parked at the end of the driveway, got out, and shut the door. He and the arresting officer met ten to twelve feet from his car, and the officer arrested and handcuffed him immediately.2 Two earlier arrestees already occupied the only patrol cars at the scene, so the officers called for backup, and two more officers arrived and locked Gant in the back seat of their vehicle.3 Only then did officers search his car, where one found a gun and another found a bag of cocaine in the pocket of a jacket on the back seat.4
Gant moved to suppress the cocaine, arguing that Belton did not authorize the search because he posed no threat once handcuffed and because he had been arrested for a traffic offense for which no evidence could be found in his car. Asked at the suppression hearing why the car was searched, the arresting officer answered, "Because the law says we can do it."5 That answer accurately described how the broad reading of Belton had been taught to officers and relied on for twenty-eight years.6 It also exposes the flaw in the rule. Authority to search that does not depend on whether the reasons for the exception are present leaves an officer able to justify a search only by pointing to the rule itself.
The Court agreed with the Arizona Supreme Court that the search was unreasonable, and it replaced the automatic rule with two conditions. After arresting an occupant or recent occupant of a vehicle, police may search the passenger compartment incident to the arrest only if (1) the arrestee is unsecured and within reaching distance of the compartment at the time of the search, or (2) it is reasonable to believe the vehicle contains evidence of the offense of arrest.7 That holding confines the old compartment rule to circumstances in which the arrestee can access the vehicle or evidence of the offense may be inside.8
Each prong has its own source, and so each has its own reason. The reaching-distance prong comes from Chimel. The exception exists because an arrest creates a risk that the arrestee will use a weapon or destroy evidence, and Chimel limited the search to the arrestee's person and the area within immediate control so that the search stays proportioned to those two purposes.9 When there is no possibility that the arrestee could reach the area police want to search, both justifications are missing and the exception does not apply, and the Court held that those same justifications fix the scope of Belton.10 Experience supplied a second reason to revise the rule. Belton assumed that articles in the compartment are generally within an arrestee's reach, but over the following 28 years the assumption proved unfounded, because those articles are rarely within reach of an arrestee who has been secured. Blind adherence to it would have authorized many unconstitutional searches, including searches of people guilty of nothing more than traffic violations.11 Gant's own facts show the mechanism: a handcuffed man in a locked patrol car cannot lunge for a jacket on a back seat, yet the automatic rule would have let the officers open it.
The dissent argued that police reliance on Belton called for a different result. The Court answered that many of the searches done in reliance had not been justified by the Chimel reasons, and that a law enforcement entitlement to a practice does not outweigh the interest every individual has in the protection of constitutional rights. It added that stare decisis does not require approving routine constitutional violations, and it pointed to the exception's own history, in which the Court reversed course repeatedly between Marron in 1927 and Chimel in 1969.12 Correcting the rule once more was therefore consistent with how the doctrine had developed.
The second prong has a different source and a different reason. The Court took it from Justice Scalia's opinion concurring in the judgment in Thornton and rested it on circumstances unique to the automobile context, with no reliance on Chimel's reaching-distance rule.13 Riley v. California later described it in the same way, as an independent exception for the passenger compartment that stems from the vehicle setting.14 Because the prong does not depend on reach, securing the arrestee does not defeat it. The belief must concern evidence of the offense of arrest, which keeps the prong from turning every arrest into a general search of the car.
The prongs are alternatives, and satisfying either prong is enough. A student who requires the arrestee to be within reach before applying the evidence prong has merged two separate justifications into one, and a student who treats every arrest as satisfying the evidence prong has erased the limit that Gant added. The next three subsections take the prongs in order and then the case in which neither applies.
Reaching-Distance Prong
The first prong applies Chimel's reasoning to a car without any shortcut. Police may search the passenger compartment when the arrestee is unsecured and within reaching distance of it at the time of the search.16 Each part of that phrase is a separate question. An arrestee is unsecured when nothing, such as handcuffs or a locked patrol car, stands between the arrestee and the compartment, and an arrestee is within reaching distance when the compartment is close enough to be grabbed. Both conditions are measured when the search happens, because the justification is a present danger. An arrestee who could have lunged for a weapon or destroyed evidence a minute ago presents neither risk once handcuffed in a cruiser.17 Students lose this prong when they ask where the arrestee stood during the arrest instead of at the time of the search.
Gant is the clearest picture of a search that fails the prong. He was handcuffed and locked in the back of a patrol car when the officers searched, so he could not have reached into his car to retrieve a weapon or evidence, and the search-incident-to-arrest exception did not justify it.18 Belton lies on the other side of the comparison. As the Court described it, the officer there had not handcuffed the four arrestees but had only separated them along the roadway, and the question the Court agreed to decide described them as standing unsecured around the car.19 What distinguishes the two cases is the arrestee's condition when the search began. Belton presumed that an occupant's arrest put the compartment within reach whatever the arrestee's actual situation, and Gant stopped presuming and made the unsecured, within-reach showing an element of the prong.20
Because officers can remove the reach question by securing the arrestee, the prong does its work mainly where they have not been able to. The typical case is a lone officer or a small group dealing with several arrestees at once, where an unsecured arrestee remains within reach of the compartment and there are too few officers to restrain that person.21
On an exam stem, the fact to find is how the arrestee was held when the search began. Handcuffs and a locked patrol car ordinarily end the inquiry under this prong, and the evidence prong then becomes the only route left within the arrest exception.
Evidence-of-Offense Prong
The second prong asks a different question. Instead of asking whether the arrestee can reach the car, it asks whether the arrest gives reason to expect that the car holds proof of the crime for which the arrestee was arrested. When it is reasonable to believe the vehicle contains evidence of the offense of arrest, police may search the passenger compartment even though the arrestee is handcuffed and out of reach.23 The Court took this condition from Justice Scalia's separate opinion in Thornton and grounded it in circumstances unique to vehicles, which is why the arrestee's inability to reach the car does not defeat it.24
The prong is tied to the offense of arrest for a structural reason. Without that tie, any arrest, however minor, would open the passenger compartment to a search for evidence of anything, and the automatic search Gant ended would come back under another name. The offense of arrest defines what the arrest itself gives officers reason to look for, so the limit keeps the search proportioned to its justification in the way the reach limit does for the first prong. A belief that the car holds evidence of some other crime does not satisfy the prong.
Gant's own arrest shows the prong failing. He was arrested for driving with a suspended license, and the officers had already confirmed the suspension and the warrant through a records check, so there was nothing further in the car that could show that offense.25 The Court affirmed that the search was unreasonable, which means the evidence prong did not rescue it.26 Belton's facts point the other way. The officer there smelled burnt marijuana, saw an envelope marked "Supergold" that he associated with marijuana, and arrested the occupants for a drug offense.27 Applied to those facts, the second prong would very likely support a compartment search today, because an officer who has just smelled marijuana and seen an envelope associated with it has grounds to expect more evidence of marijuana possession inside the car.
The twin isolates one variable, which is what the offense of arrest implies about the contents of the car. The arrestee's security, the vehicle, and the space searched were the same in both versions.
When Neither Prong Applies
When the arrestee is secured and out of reach and the offense of arrest gives no reason to expect evidence in the car, the incident-to-arrest exception has nothing left to stand on. A search of the arrestee's vehicle is then unreasonable unless police obtain a warrant or show that another exception to the warrant requirement applies.29 The default explains the result. A warrantless search is presumptively unreasonable unless it fits one of a few well-established exceptions, and the search-incident-to-arrest exception is one of them only because of the dangers and evidence concerns that attend an arrest.30 Once the facts remove those concerns, the exception's authority is gone, and what remains is an ordinary warrantless search.
Other routes to a lawful search remain open, but they rest on their own requirements. Officers who secure the car can ask a judge for a warrant. The automobile exception can independently support a search when police have reasonable cause to believe the vehicle contains evidence related to a crime, and it looks to what the officers know about the car's contents, so it can apply whether or not an arrest has occurred.31 Gant's search relied on neither, since the officers had no warrant and invoked only the arrest.
The cocaine found in Gant's jacket does not change the analysis. Both prongs look to circumstances that exist before the search begins, namely whether the arrestee could reach the compartment and whether officers had reason to expect evidence of the offense of arrest, so what a search turns up cannot supply a missing justification.32
In the second version the arrest does no work. A different doctrine supplies the justification, and an exam answer should name that doctrine instead of leaning on the arrest.
Reaching-Distance Prong
The first prong of the test in Arizona v. Gant carries Chimel's reasoning into the car without a shortcut. Police may search the passenger compartment incident to the arrest of an occupant or recent occupant when the arrestee is unsecured and within reaching distance of the compartment at the time of the search.34 The condition follows from what the exception is for. A search incident to arrest is reasonable because the arrestee might grab a weapon or conceal or destroy evidence, so Chimel limits the search to the area from which the arrestee might gain possession of a weapon or destructible evidence.35 When there is no possibility that the arrestee could reach the area officers want to search, both justifications are missing and the exception does not apply.36 Gant applied that logic to vehicles by holding that the safety and evidence concerns behind Chimel's reaching-distance rule determine how far Belton's rule extends.37
The prong breaks into three questions, and each is answered from the facts as they stood when the search began. An arrestee is unsecured when nothing, such as handcuffs or confinement in a patrol car, prevents the arrestee from moving toward the compartment. An arrestee is within reaching distance when the compartment is close enough that the arrestee could actually get to it. Both conditions are measured at the time of the search, because the justification is a danger that exists now, not one that existed a few minutes earlier. Courts therefore ask what places the arrestee could presently reach, and they weigh practical facts such as these:
- whether the arrestee has been restrained, as by handcuffs;
- where the officers stand in relation to the arrestee and to the place searched;
- how easy or hard it is to get into the container or enclosure being searched;
- how many officers are present compared with the number of arrestees and other people at the scene.38
These factors all go to physical possibility, and Gant's own arrest shows how they combine. Gant parked, got out of his car, and shut the door, and Officer Griffith arrested and handcuffed him about 10 to 12 feet from the car. Two backup officers then locked him in the back of their patrol car, and only after that did two officers search his car and find a gun and a bag of cocaine in a jacket pocket on the backseat.39 Every factor pointed the same way, because Gant was restrained and confined in a patrol car and could not have accessed his car to retrieve a weapon or evidence when the search occurred.40 Asked at the suppression hearing why the search was conducted, Officer Griffith answered, “Because the law says we can do it.”41 That answer treats the arrest as the whole justification and skips the question this prong requires officers to ask about the arrestee's reach.
New York v. Belton lies on the other side of the comparison, and the two cases differ in exactly the fact the prong measures. A lone officer in Belton stopped a speeding car with four occupants, smelled burnt marijuana, saw an envelope marked “Supergold,” arrested the occupants, and patted them down.42 Without handcuffing them, the officer separated them into four different spots along the Thruway so that none would be within touching distance of another, and then searched the car, including a jacket pocket on the backseat where he found cocaine.43 The question the Court agreed to review described the four arrestees as standing unsecured around the vehicle.44 Both cases involved a backseat jacket with cocaine in it, but the Belton arrestees were unrestrained at the scene when the search happened, so the dangers Chimel describes were live, while Gant had been handcuffed and locked away before the search began. The arrestee's condition at the time of the search is therefore the fact that moved the answer, and Gant holds that the arrest alone no longer justifies a compartment search once the arrestee has been secured and cannot access the interior.45
Because the prong looks to the moment of the search, and because officers control that moment, it often fails in practice. A handcuffed arrestee seated in a locked patrol car has no way to reach the car, so securing the arrestee first removes the justification before the search starts. The prong does its real work where officers have not yet been able to secure everyone, which is why the ratio of officers to arrestees appears among the factors above: a lone officer facing several arrestees may still have an unrestrained one standing at the car.46
On an exam stem, the fact to find is how the arrestee was held when the search began, not where the arrest took place. Handcuffs and a locked patrol car ordinarily end the inquiry under this prong, while an unrestrained arrestee within arm's length of the compartment, especially with officers outnumbered, usually satisfies it. When the first prong fails, the analysis moves to the evidence-of-offense prong, which does not depend on reach.
Evidence-of-Offense Prong
The reaching-distance prong looks at the arrestee, while the second prong of Arizona v. Gant looks at the car. When it is reasonable to believe that the vehicle contains evidence of the offense of arrest, police may search the passenger compartment incident to the arrest of an occupant or recent occupant, and the arrestee's inability to reach the compartment does not defeat the search.48 Gant took this condition from the suggestion in Justice Scalia's opinion concurring in the judgment in Thornton v. United States, the decision that had extended Belton to an arrestee first approached after leaving the car.49 Handcuffs and a locked patrol car end the first prong, but they have no effect on this one, because nothing in it asks where the arrestee is.
The origin of the prong explains why reach plays no part in it. The safety and evidence concerns behind Chimel's reaching-distance rule set the limits of the first prong, and both concerns depend on what the arrestee could grab.50 Riley v. California later described the evidence-of-offense condition as an exception that stems not from Chimel but from “circumstances unique to the vehicle context.”51 The justification here is the likely contents of the car. A vehicle is a place where proof of a crime is often kept, and some arrests give officers a concrete reason to expect that proof inside it, whether or not the arrestee could ever get to it.
The words “of the offense of arrest” confine the prong, and the confinement has a structural reason. The charge defines what proof officers can expect to find. An arrest for possessing drugs implies that drugs, or related items, may be in the car, while an arrest for driving on a suspended license implies nothing of the kind, because that offense is proved by a records check and not by anything in the passenger compartment. If the prong reached evidence of any crime an officer happened to suspect, an arrest for even a trivial offense would work as a key to the compartment, and the automatic search that Gant ended would return under a new label. The question is therefore always what the offense of arrest implies about the car, and a belief that the car holds evidence of some other crime does not satisfy the prong.
The two sides of the line appear in the two cars this chapter has already followed. In New York v. Belton a trooper stopped a speeding car with four men in it, smelled burnt marijuana, and saw on the floor an envelope marked “Supergold” that he associated with marijuana, and he arrested the men for unlawful possession of marijuana.52 The smell and the envelope are signs that marijuana is in the passenger compartment, so the offense of arrest and the facts at the scene point to evidence in the car. Belton was decided under the older automatic rule, but on those facts the second prong would very likely support a compartment search today even if every arrestee were secured. The cocaine the trooper later found in a jacket pocket does not change this, because the prong asks what officers had reason to expect before they searched.
Gant is the other pole. He was arrested for driving with a suspended license after officers had already learned of the suspension and the warrant through a records check, and he argued that he was arrested for a traffic offense for which no evidence could be found in his car.53 The Court agreed that the search-incident-to-arrest exception did not justify the search of his car.54 Both cars held cocaine in a backseat jacket pocket, and the difference this prong cares about is the offense. A marijuana arrest supplies a reason to expect more evidence in the car, and a suspended-license arrest, proved by records, does not.
The twin changes a single fact, which is what the arrest was for. On an exam stem the prong is best run in three moves.
Drug and theft arrests will often satisfy step two, while arrests for traffic offenses generally will not, because those offenses leave nothing in the car to find.
When Neither Prong Applies
The two prongs of Arizona v. Gant are the only ways the arrest itself can justify entering the passenger compartment, so the analysis reaches a definite endpoint when both fail. If the arrestee is secured and out of reach, and nothing about the offense of arrest makes it reasonable to believe the car holds evidence of that offense, the search-incident exception supplies no authority for the search. Gant states the consequence directly: when those justifications are absent, a search of the arrestee's vehicle is unreasonable unless police obtain a warrant or show that another exception to the warrant requirement applies.56 The rule follows from how exceptions work. A warrantless search is presumptively unreasonable, and an exception lifts that presumption only while the reason behind it is present.57 The reasons behind this exception are the officer-safety and evidence-preservation concerns of Chimel, and both disappear once the arrestee cannot reach the car and the offense leaves no proof inside it. What remains is the bare fact of arrest, and Gant refused to treat that fact as sufficient, observing that the broader reading of the earlier rule had exposed countless people guilty of nothing worse than a traffic violation to searches of their private effects.58
Gant's own arrest is the clearest example of the failing case. He was arrested for driving on a suspended license, handcuffed, and locked in a patrol car, and only then did officers search his car and find cocaine in a jacket pocket.59 He could not reach the compartment, so the first prong failed, and a suspended-license arrest gave no reason to expect evidence of that offense in the car, so the second prong failed too. The Court affirmed the Arizona Supreme Court's conclusion that the search was unreasonable, which left the cocaine subject to suppression.60
That result closes only the search-incident route into the car. Because the holding turns on a warrant or another exception, every independent basis for a vehicle search survives it, and each stands on its own conditions instead of on the arrest. Under the automobile exception, officers who have probable cause to search the vehicle may search the passenger compartment as part of that vehicle search, and the arrest adds nothing to the justification.61 An inventory search carried out under standardized procedures rests on its own purpose, which is to ensure that police are not storing dangerous or illegal items, and it does not depend on the arrest-based theory.62 A protective search under Michigan v. Long lets officers search the passenger compartment, even without an arrest, when specific facts support a reasonable belief that a suspect is dangerous and may gain immediate control of a weapon there.63 Each of these has its own elements and belongs to a separate reading, and here they matter only as proof that the arrest need not carry the whole case.
An exam answer should keep going after the arrest-based theory fails. The next questions are whether a warrant exists, whether the facts supply probable cause to search the car, whether a standardized inventory is underway, and whether specific facts point to a dangerous suspect with access to a weapon. If the stem offers none of these, the search is unreasonable and the evidence is subject to suppression, and a stem describing only a secured arrestee, a minor offense, and a compartment search is the Gant pattern. The structure preserves what law enforcement legitimately needs: where officers have real cause to search a car, a doctrine built around that cause is available, and where they hold only an arrest for a minor offense, the arrest alone does not open the car. Letting it do so would turn every traffic arrest into a license to search the vehicle, which is the result the holding prevents.
