David Karson’s pickup truck was searched in 2007 after a police officer arrested him on a warrant. At the time, pretty much all courts in the United States — and certainly those with jurisdiction over Kansas police officers — said it was legal to search the passenger compartment of a car any time one of its occupants was arrested. Drugs and drug paraphernalia were found in Karson’s truck, and he was convicted of drug charges.
But in 2009, the United States Supreme Court concluded that a vehicle could not be searched merely because an occupant had been arrested when, as was true in Karson’s case, the defendant was already handcuffed and in the back of a patrol car. Karson now argues that the evidence against him should have been excluded because his constitutional rights were violated. But the purpose of the exclusionary rule is not served here: we cannot fault law-enforcement officers for following the law as it was being uniformly interpreted by the courts at the time. The purpose of the exclu *307 sionary rule is to deter wrongful conduct by police, not to suggest that they should be leery of following what courts have told them is the law. We therefore conclude that the good-faith exception to the exclusionary rule applies here, and we affirm the defendant’s convictions.
The facts of Karson’s case are simple and undisputed. Karson parked his pickup at a Quik Trip, where an officer performed a routine check on the license plate. During that check, the officer found that it was registered to Karson and that Karson had an outstanding arrest warrant for a traffic violation. After securing Karson in the back of the officer’s patrol car, the officer searched Karson’s pickup.
Let’s review the legal landscape at the time of the search. The Fourth Amendment protects our right to be secure in our persons, houses, papers, and effects against unreasonable searches and seizures. Caselaw interpreting the Fourth Amendment tells us that a search without a warrant is unreasonable unless it falls within one of several limited, well-defined exceptions to the warrant requirement.
State v.
Thompson,
In
Chimel,
the Court ruled that officers couldn’t search an entire home when arresting the owner on a burglary charge. The Court held that a search incident to arrest was limited to a search of the person “to remove any weapons” and “to search for and seize any evidence on the arrestee’s person in order to prevent its concealment or destruction.”
In
Belton,
an officer stopped a car for speeding and smelled burnt marijuana when he approached the car to check the driver’s license and registration. The officer had all four men.in the car step out, and he then searched the passenger compartment of the car, including a closed pocket in Belton’s jacket, where he found cocaine. Much as
Chimel
had held that an officer arresting a person in a home couldn’t open a drawer searching for evidence, the New York Court of Appeals held that an officer couldn’t search the contents of a car — or the pocket of a jacket found there — without a warrant after the occupants had been removed. But the Supreme Court didn’t agree, even though it also didn’t overrule
Chimel.
The Court noted that lower courts had split on whether an officer could search a car incident to an arrest when the arrestee was no longer in the car. The Court concluded that both citizens and police needed a “workable definition of ‘the area within the immediate control of the arrestee.’ ”
In
Thornton,
two justices criticized the theoretical tension between
Chimel,
which based its exception to the warrant requirement on the needs either to protect officer safety or to preserve
*309
evidence that might easily be concealed or destroyed.
So as of 2007, when an officer searched Karson’s pickup, the Court had announced a rule in Belton that allowed the search of the passenger compartment, including containers found there, whenever an occupant had been arrested. And in Thornton, the Court had applied that rule even when the person arrested had first been approached by an officer outside the car, given the need for a clear rule police officers could follow.
How was the
Belton
rule understood in 2007 by courts below the United States Supreme Court? Both the Kansas Supreme Court and the United States Court of Appeals for the Tendí Circuit, the two courts whose decisions effectively govern the work of police officers in Kansas, concluded that
Belton
set out a clear rule. As our Supreme Court reported in 1995, 14 years after
Belton,
“Kansas courts have consistendy applied
Belton
to allow an officer to search the passenger compartment of an automobile when its occupant is arrested.”
State v. McClain,
*310
So far we have discussed only cases about the reasonableness of an automobile search incident to arrest under the Fourth Amendment or its Kansas counterpart. But there’s also one statutory issue that was in play for a time in Kansas that we must mention. A year after our Supreme Court had noted in
McClain
the consistent application of
Belton
to allow car searches incident to arrest, the court recognized that a Kansas statute, K.S.A. 22-2501, contained some limits on police authority not found in
Belton.
See
State v. Anderson,
The 2006 Kansas Legislature addressed that statutory hurdle to the search for evidence in a car unrelated to an occupant’s specific crime of arrest. It amended K.S.A. 22-2501 to allow search for “evidence of
a
crime” rather than “evidence of
the
crime.” (Emphasis added.) L. 2006, ch. 211, sec. 8. Before the Supreme Court’s decision in
Arizona v. Gant,
Thus, as of 2007 when Karson s car was searched, the Belton rule had been recently reaffirmed by the United States Supreme Court in Thornton. Both the Kansas Supreme Court and the Tenth Circuit had consistently apphed Belton, and the Kansas Legislature had amended K.S.A. 22-2501 so that the statute would allow a search to the extent allowed by Belton. Any officer in Kansas would have reasonably understood that he or she could search a car incident to arrest.
Later, in 2009, the United States Supreme Court decided
Gant,
which is for all practical purposes indistinguishable from Karson’s case. The Court held that, with one exception, you can’t search a car merely because an occupant has been arrested when the arrestee has already been secured outside the car. The single exception is when it’s reasonable to expect that evidence relevant to the crime of arrest may be found in the car.
Karson argues that the
Gant
holding must be apphed to all other cases that, like his, were still pending on appeal when
Gant
was decided. Karson is right about that. See
Griffith v. Kentucky,
The United States Supreme Court has made clear in several cases that even though a search may have been constitutionally impermissible, the evidence may yet be admissible. In
United
*312
States v. Leon,
• an apparently valid search warrant that was later held not to have been based on sufficient probable cause for its issuance by a magistrate,
Leon,
• an apparently valid search warrant that was later held invalid due to the magistrate’s failure to cross out extraneous language on the warrant when the magistrate had told the officer executing the warrant that the magistrate would conform the draft warrant presented to him to legal requirements,
Massachusetts v. Sheppard,
• an erroneous record entered by a court employee stating that a warrant was outstanding for a person’s arrest,
Arizona v. Evans,
• an erroneous record entered by a police record keeper stating that a warrant was outstanding for a person’s arrest,
Herring v. United States,
• an apparently valid statute that was later held unconstitutional,
Illinois v. Krull,
In the most recent of these decisions,
Herring,
the Court extended its earlier holding in
Evans,
in which police reliance on negligent record keeping by a court employee was held objectively reasonable, to police reliance on negligent record keeping by a fellow law-enforcement employee. The Court noted that the benefits of deterrence must outweigh the cost of excluding evidence
*313
for the exclusionary rule to be applied.
Herring, 555
U.S. at 141. Of course, what we’re trying to deter is future constitutional violations, an objective the Court has said is furthered only when officers either have knowledge that their conduct is unconstitutional or may properly be charged with that knowledge.
The essence of the Court’s good-faith cases is that the exclusionary rule is based on its deterrence of misconduct, and when officers are acting in an objectively reasonable manner, there’s no misconduct to deter by excluding evidence in criminal trials. Surely police reliance on settled caselaw is objectively reasonable.
The Court’s cases have also made clear that it ordinarily makes no sense to apply the exclusionary rule to mistakes of those outside law enforcement, whether it’s a judicial officer, Leon and Sheppard, a judicial employee, Evans, or the legislature, Krull. When, as was the situation for caselaw interpreting Belton, there is a well-settled, established understanding within which officers have acted, “excluding evidence based on judicial error would serve no deterrent purpose.” United States v. McCane, 573 F.3d 1037, 1045 (10th Cir. 2009).
Beyond the bright-line rule of
Belton,
we noted previously that there was for a time a statutory limitation on police authority to perform searches in Kansas. But that was resolved — as of 2007— with a 2006 statutory amendment to K.S.A. 22-2501 that broadened an officer’s search authority to the constitutional limit set out in
Belton.
Our court so held,
Henning,
*314 We conclude that a police officer who conducts a search in reasonable reliance upon the settled caselaw of the Kansas Supreme Court and the United States Court of Appeals for the.Tenth Circuit has not engaged in misconduct even if a later United States Supreme Court decision deems the search invalid. Accordingly, under the good-faith exception to the exclusionary rule, evidence found in such a search is not excluded based on the search’s invalidity.
On this issue, we are in accord with the majority of courts, which have concluded that the good-faith exception applies to searches conducted in accordance with the prevailing understanding of the
Belton
rule before
Gant
was decided. Compare
McCane,
Karson has argued that we must rule in his favor to uphold the retroactive application of Supreme Court decisions to cases then pending, and we acknowledge that some courts have agreed with his position.
E.g., Gonzalez,
The judgment of the district court is affirmed.
