In this interlocutory appeal the People challenge an order suppressing a small packet of cocaine seized from a purse belonging to the defendant, Patricia J. Inman, during an inventory search performed at a county jail in the course of booking the defendant for drunk driving. We conclude that the district court applied an incorrect legal standard with respect to the scope of a permissible inventory search upon arrest, and we accordingly reverse the order of suppression.
I.
The defendant was charged with the crimes of unlawful possession of cocaine, 1 unlawful possession of not more than one ounce of marijuana, 2 and operating a motor vehicle while her ability to drive was impaired by the consumption of alcohol, 3 all of which were alleged to have occurred on December 23, 1987, in Montezuma County, Colorado. After entering a plea of not guilty to the charges, the defendant filed a motion to suppress the cocaine and marijuana, claiming that the seizure of these materials from her purse violated the *578 Fourth and Fourteenth Amendments to the United States Constitution and article II, section 7 of the Colorado Constitution.
The evidence at the suppression hearing was uncontradicted and established the following sequence of events. On December 23,1987, at approximately 1:56 a.m., patrolman Eric Souders of the Cortez Police Department observed a car traveling west on East Main Street in Cortez without any taillights. The officer pulled over the vehicle, approached the car, and spoke with defendant who was driving the vehicle. During their conversation Officer Souders noticed that the defendant’s speech was slurred and that her breath smelled of an alcoholic beverage. At the officer’s request, the defendant agreed to perform some roadside sobriety maneuvers. Because the defendant’s performance was unsatisfactory, Officer Souders informed her that she was under arrest for drunk driving. The defendant was carrying a purse at this time, so the officer took the purse and placed it on the passenger seat of the police vehicle. Souders released the defendant’s vehicle to the passenger who was riding with her when the stop occurred, and then placed the defendant in the police vehicle and drove her to the Montezuma County Jail.
At the jail Souders gave the defendant’s purse to Officer Crystal Baxter, who was a detention officer at the jail, so that Baxter could perform an inventory search of the contents of the purse. The inventory search of the purse was part of the routine booking procedure at the county jail. Upon Baxter’s initial inspection of the contents of the purse, she discovered two bags containing a green leafy substance which was later determined to be marijuana. Baxter then gave the purse to Souders, who was assisting her in the booking process, so that Souders could make a further check of any items which Baxter might have overlooked. Souders, in examining the inside of the purse, located a small cosmetic bag inside the main compartment. Upon opening the cosmetic bag the officer observed a small packet of brown paper about the size of a half-dollar. Souders opened the paper packet and saw that it contained a white powdery substance which was later determined to be cocaine.
The district court, in granting the motion to suppress, ruled that Officer Souders had probable cause to arrest the defendant for drunk driving and that Officer Baxter properly took account of the contents of the defendant’s purse as part of the routine booking procedure at the county jail and thus properly seized the marijuana from the purse. With respect to the brown paper packet inside the small cosmetic bag, however, the district court ruled that the officers had no reason to suspect that the. packet contained contraband and that, therefore, the seizure of the packet and the examination of its contents exceeded the legitimate purposes of an inventory search and constituted an unlawful search and seizure. The district court accordingly suppressed the brown paper packet, the cocaine inside the packet, and any other evidence or testimony regarding the packet and its contents.
Pursuant to C.A.R. 4.1, the People thereafter filed this interlocutory appeal. The People claim that the district court applied an erroneously restrictive standard in ruling that Officer Souders’ seizure of the paper packet and his examination of its contents were beyond the scope of a constitutionally permissible inventory search. We agree with the People’s argument.
II.
Appellate review of a suppression ruling is limited to the legal bases set forth in the district court’s ruling and not necessarily the grounds alleged in the motion. Although the defendant’s motion to suppress cited both the United States and the Colorado Constitutions, the district court failed to state in its ruling whether the order of suppression was based on federal or state constitutional standards. In the absence of a clear statement that a suppression ruling is grounded on state as opposed to federal constitutional law, we will presume that a court relied on federal law in reaching its decision.
See Michigan v. Long,
The controlling federal standards applicable to this case were clearly articulated by the United States Supreme Court in
Illinois v. Lafayette,
The Supreme Court noted in
Lafayette
that “[a] so-called inventory search is not an independent legal concept but rather an incidental administrative step following arrest and preceding incarceration,”
Lafayette,
In reaching its decision in Lafayette, the Court rejected the argument that the police might have searched the defendant’s prop *580 erty by employing less intrusive means, such as sealing the shoulder bag within a plastic bag or box and placing it in a secured locker:
We are hardly in a position to second-guess police departments as to what practical administrative method will best deter theft by and false claims against its employees and preserve the security of the station house. It is evident that a station-house search of every item carried on or by a person who has lawfully been taken into custody by the police will amply serve the important and legitimate governmental interests involved.
Even if less intrusive means existed of protecting some particular types of property, it would be unreasonable to expect police officers in the everyday course of business to make fine and subtle distinctions in deciding which containers or items may be searched and which must be sealed as a unit.
Id.
at 648,
Four years after the Supreme Court’s decision in
Lafayette v. Illinois,
the Court in
Colorado v. Bertine,
We think that such a requirement is contrary to our decisions in Opperman and Lafayette, and by analogy to our decision in United States v. Ross,456 U.S. 798 [102 S.Ct. 2157 ,72 L.Ed.2d 572 ] (1982):
“Evén if less intrusive means existed of protecting some particular types of property, it would be unreasonable to expect police officers in the everyday course of business to make fine and subtle distinctions in deciding which containers or items may be searched and which must be sealed as a unit.” Lafayette, supra [462 U.S.] at 648 [103 S.Ct. at 2610 ].
“When a legitimate search is under way, and when its purpose and its limits have been precisely defined, nice distinctions between closets, drawers, and containers, in the case of a home, or between glove compartments, upholstered seats, trunks, and wrapped packages, in the case of a vehicle, must give way to the interest in the prompt and efficient completion of the task at hand.” United States v. Ross, supra [456 U.S.] at 821 [102 S.Ct. at 2171 ].
We reaffirm these principles here: “ ‘[a] single familiar standard is essential to guide police officers, who have only limited time and expertise to reflect on and balance the social and individual interests involved in the specific circumstances they confront.’ ” See Lafayette, supra [462 U.S.] at 648 [103 S.Ct. at 2610 ] (quoting New York v. Belton,453 U.S. 454 , 458 [101 S.Ct. 2860 , 2863,69 L.Ed.2d 768 ] (1981)).

*581 III.
The decisions of the United States Supreme Court in Lafayette and Bertine compel the reversal of the suppression order entered in this case. In suppressing the cocaine, the district court relied on the faulty premise that some independent justification, other than the defendant’s arrest for drunk driving and the routine booking procedure incident to that arrest, was required before the officers could constitutionally seize the paper packet from the defendant’s purse and examine the contents of the packet. The arrest of the defendant for drunk driving and the booking procedure at the county jail furnished an adequate constitutional basis for the police to seize and examine all the items recovered from the defendant’s person or possession, including articles in her purse, and to open any container inside the purse and examine its contents. The officers, in other words, had the right to conduct a complete inventory of the defendant’s possessions without regard to whether they harbored any subjective concern that a particular item might contain a dangerous substance which could thereafter threaten jail security or might contain a valuable object for the loss of which the officers could conceivably be held responsible. Under the circumstances of this case, the seizure of the paper packet and the examination of its contents comported with federal constitutional standards applicable to a routine inventory search incident to the defendant’s arrest and jailhouse detention for a crime, and the district court erred in ruling to the contrary.
The order of suppression is accordingly reversed.
