Plaintiff-Appellant Robert E. Thompson appeals pro se the district court's dismissal of his civil rights action as to defendant Board of Regents of the University of California and the district court’s grant of summary judgment in favor of the County of Los Angeles. Thompson’s complaint alleged he was not promptly arraigned after his warrantless arrest in violation of his Fourth Amendment rights, and that prior to his unconditional release from jail more than five days after his arrest, he was subjected to unconstitutional prison procedures and conditions in violation of his Fourth Amendment rights and due process rights under the Fourteenth Amendment. We affirm in part and reverse in part.
I.
On the evening of Thursday, July 18, 1985, a UCLA police officer observed an automobile with out-of-date registration tags parked at an expired parking meter. A check of the vehicle’s license plate through the police communication system revealed that the automobile had been reported stolen. At about 8:40 p.m., Thompson entered the vehicle. As he began to drive away, he was immediately stopped by UCLA police officers and arrested for grand theft auto. While in the custody of *1442 the UCLA Police, Thompson was fingerprinted, photographed, and booked.
Soon after his arrest by the UCLA Police, Thompson was transported to the West Hollywood Sheriff’s Station, where he was again booked and charged. Thompson remained at the West Hollywood Sheriff’s Station until the morning of July 19, 1985. He was then transferred to the Los Angeles County Central Jail [hereinafter “County Jail”]. Upon entering the County Jail, Thompson, in accordance with the County of Los Angeles policy, was subjected to x-rays, a blood test, and a strip search. While in the County Jail, Thompson also alleged that he was forced to spend two nights on the floor of a prison cell without a mattress. On the morning of Wednesday, July 24, 1985, Thompson was unconditionally released from county jail; he was never arraigned for grand theft auto or any other charge.
On January 6, 1986, Thompson filed a complaint under 42 U.S.C. §§ 1983, 1981, and 1985 against the City of Los Angeles, the County of Los Angeles [hereinafter “the County”], Full-Service Car Rental System,' and the Regents of the University of California at Los Angeles [hereinafter “UC”]. While Thompson named no individual defendants, he did include Does 1-20 as defendants.
Thompson’s civil rights complaint alleged, inter alia, that both UC and the County had violated his Fourth Amendment rights by failing to arraign or release him within a reasonable period following his warrantless arrest, that the forced submission to x-rays, a blood test, and strip search constituted an illegal search under the Fourth Amendment and violated his Fourteenth Amendment right to due process of law, and that the County’s failure to provide him with a bed in the County Jail constituted a deprivation of his Fourteenth Amendment rights. 1
The district court subsequently disposed of all of Thompson’s claims in favor of all named defendants. Specifically, with respect to Thompson’s allegations against UC, the district court dismissed for failure to state a claim. As for the County, the district court initially denied the County’s motion for judgment on the pleadings, but then subsequently granted the County’s motion for summary judgment as to all causes of action.
II.
A dismissal for failure to state a claim is a ruling on a question of law and is thus subject to de novo review.
Fort Vancouver Plywood Co. v. United States,
III.
The district court clearly did not err in dismissing all of Thompson’s claims against UC since, as a state instrumentality for Eleventh Amendment purposes, it is not subject to a suit for damages under § 1983. Section 1983 provides, in relevant part, that “every person who subjects or causes to be subjected any citizen of the United States ... to the deprivation of any rights, privileges or immunities secured by the Constitution and laws, shall be liable to the party in an action at law, suit in equity or other proper proceeding to redress.” Accordingly, only those governmental enti
*1443
ties which are “persons” within the meaning of § 1983 can be held liable under § 1983. While it is well-settled that local governmental bodies such as municipalities and counties are “persons” within the meaning of § 1983,
see Monell v. New York City Dep’t of Social Services,
It has long been established that UC is an instrumentality of the state for purposes of the Eleventh Amendment.
Hamilton v. Regents,
IV.
Before discussing Thompson’s individual constitutional claims against the County, we first shall review briefly the general principles governing § 1983 actions against local governmental entities. As noted above, the Supreme Court in
Monell
held that local governmental bodies, such as counties, are persons under § 1983 and therefore may be sued under the statute for constitutional injuries.
Monell
went on to state, however, that a local governmental body cannot be found liable under § 1983 on a respondeat superior theory; liability may be imposed only if the plaintiff establishes that his injuries were inflicted pursuant to an official county policy or custom.
See Monell,
While a rule or regulation promulgated, adopted, or ratified by a local governmental entity’s legislative body unquestionably satisfies Monell’s policy requirement,
see Monell,
With respect to custom, the Court in
Monell
asserted that “although the touchstone of the § 1983 action against a government body is an allegation that official policy is responsible for a deprivation of rights protected by the Constitution, local governments ... by the very terms of the statute, may be sued for constitutional deprivations visited pursuant to governmental ‘custom’ even though such a custom has not received formal approval through the body’s official decision-making channels.”
Monell,
If such a showing is made, however, a local government may be liable for its custom irrespective of whether official policymakers had actual knowledge of the practice at issue. The existence of custom as a basis for liability under § 1983 thus serves a critical role in insuring that local government entities are held responsible for widespread abuses or practices that cannot be affirmatively attributed to the decisions or ratification of an official government policymaker but are so pervasive as to have the force of law. See id.
A.
With these principles in mind, we turn our attention to Thompson’s individual constitutional claims against the County to determine whether the district court properly granted summary judgment in the County’s favor.
Thompson first claims that his prolonged detention of more than five days without a probable cause determination violated his Fourth Amendment rights. While the record indicates that Thompson may indeed be correct that the County’s failure to bring him before a judicial officer for a probable cause determination before his release from county jail violated his Fourth Amendment rights,
see Gerstein v. Pugh,
First, Thompson has failed to allege that the Sheriff of Los Angeles County, the county official that state law indicates is the official policymaker regarding arrestee detention in County Jail, 3 promulgated, adopted, or ratified a policy of holding ar-restees for a period that exceeds the amount of time necessary to prepare for a probable cause determination. Nor does Thompson contend that any other County officials acting pursuant to delegated official policymaking authority adopted such a policy.
Moreover, Thompson does not allege that the Sheriff, or an official delegated authority by the Sheriff, made or ratified any decisions concerning the length of his particular detention. Thompson also makes no reference to a decision or policy enactment by any other county official who could conceivably be regarded as an official policymaker regarding arrestee detention. Final
*1445
ly, Thompson has failed to offer any evidence that the County maintains a custom of detaining arrestees for an excessive period of time prior to arraignment or release. Accordingly, liability may not be imposed against the County for its alleged constitutional deprivation.
See Celotex Corp. v. Catrett,
B.
Thompson next challenges his forced submission at the county jail to a strip search, x-rays, and a blood test. He contends that each of these procedures constituted unlawful searches in violation of the Fourth Amendment and violated his right to due process of law guaranteed by the Fourteenth Amendment.
The County concedes that as a matter of County policy, all new admittees to the county jail must undergo a strip search, x-ray, and blood sample. That being conceded, our task is to determine whether these policies, in the context of the particular circumstances of this case, raise factual issues sufficient to preclude summary judgment.
In recognition of the principle that pretrial detainees retain their Fourth Amendment rights within the jailhouse walls, the Supreme Court has held that searches of pretrial detainees in jail must be reasonable within the meaning of the Fourth Amendment.
Bell v. Wolfish,
The test of reasonableness under the Fourth Amendment is not capable of precise definition or mechanical application. In each case it requires a balancing of the need for the particular search against the invasion of personal rights that the search entails. Courts must consider the scope of the particular intrusion, the manner in which it is conducted, the justification for initiating it, and the place in which it is conducted.
Id.
at 559,
Upon balancing
Bell’s
factors, we conclude that none of the County’s search policies violated Thompson’s rights. With respect to the strip search, the County’s asserted justification for its policy — the prevention of the introduction of weapons or other contraband into the jail — is indeed an extremely weighty government interest.
See Bell,
The feelings of humiliation and degradation associated with forcibly exposing one’s nude body to strangers for visual inspection is beyond dispute.
See Giles,
In weighing these competing governmental and private interests, this court and several other courts have invalidated blanket visual strip search policies as applied to arrestees detained for minor traffic offenses and other misdemeanors not normally associated with weapons or other contraband.
See Weber,
The Sixth Circuit has, in contrast, upheld the strip search of an arrestee charged with the misdemeanor offense of menacing,
Dobrowolskyj v. Jefferson County,
Although Thompson, like the arrestees in
Dobrowolskyj
and
Dufrin,
was placed into contact with the general jail population, such a factor by itself cannot justify a strip search.
See Giles,
With respect to the County’s other challenged searches, we openly acknowledge the serious intrusive nature of the extraction of blood from the person,
see Schmerber v. California,
Thompson’s claim that the County’s search policies offend due process also cannot withstand summary judgment. The
Bell
Court recognized that since a pretrial detainee may not be punished prior to an adjudication of guilt in accordance with due process of law,
see Bell,
C.
Thompson also alleges that the County failed to provide him with a bed or even a mattress for two of the nights spent in county jail and that consequently he was forced to sleep on the cement floor during those nights. He claims that such deprivation violated his right to due process guaranteed by the Fourteenth Amendment. The County does not deny Thompson’s allegations that he was not provided with a bed -or mattress during a portion of his stay at the county jail. Indeed, Thompson’s allegations with respect to his sleeping conditions pass without reference or acknowledgement in the County’s brief. We find the district erred in granting summary judgment on Thompson’s constitutional'challenge to the County’s failure to provide him with'a bed.
Applying Bell’s principle that conditions of incarceration serving no legitimate governmental objective constitute punishment of pretrial detainees in violation of the Fourteenth Amendment,
Bell,
As with his Fourth Amendment claim of prolonged detention without arraignment, Thompson has failed to offer any evidence showing that the County’s failure to provide him with a bed was pursuant to County policy. He does, however, draw our attention to the case of
Rutherford v. Pitchess,
Thompson now alleges that in 1985, seven years after the
Rutherford
decision, the County again failed to provide a bed to each inmate. It is a bedrock common law principle that in certain situations, once a condition has been proven to exist, it is presumed in the absence of proof to the contrary that the condition has remained unchanged. 2 J. Wigmore, Wigmore on Evidence § 437 (J. Chadbourn rev. 1979). In light of the County’s failure either to refute Thompson’s allegation or to provide evidence of corrective measures taken to comply with the 1978 court order issued in
Rutherford,
it is appropriate to presume at this stage of the litigation that the relevant conditions declared unconstitutional in 1978 by the district court in
Rutherford
remained substandard at least through 1985. Therefore, we must also presume at this point that the County maintained a “custom” of unconstitutional jail conditions in the form of a shortage of beds and consequently may be held liable for Thompson’s injuries resulting from such a constitutional deprivation.
See Anela,
Under Fed.R.Evid. 301, “a presumption imposes on the party against whom it is going forward with evidence to rebut or meet the presumption.” Therefore, on remand, the County has the burden of coming forward with evidence that it remedied the bed shortage condition and thus that the failure to provide Thompson with a bed was a relatively isolated occurrence. The ultimate burden of proof, of course, remains on Thompson throughout the litigation. Fed.R.Evid. 301.
V.
We affirm the district court’s dismissal of all claims against UC. We also affirm the district court’s entry of summary judgment in favor of the County as to all claims except for Thompson’s allegation that the County failed to provide him with a mattress and bed. We reverse the district court’s grant of summary of judgment on this claim and remand for further proceedings consistent with this opinion. The plaintiff is entitled to his costs.
AFFIRMED IN PART, REVERSED IN PART, AND REMANDED.
Notes
. Thompson’s civil rights complaint also alleged that the City of Los Angeles and Full-Service Car Rental System conspired amongst themselves and with the other defendants to deprive Thompson of his liberty and property without due process of law. These claims are not before us on appeal, however, as Thompson has explicitly abandoned all claims against Full Service Car Rental System and the City of Los Angeles. Also unchallenged on appeal is the district court’s dismissal of Thompson's false arrest claim against UC and the district court’s rejection of §§ 1981 and 1985 as valid bases for relief in this action.
. As has been noted by this court in the past, the concurrence in
Praprotnik
disagrees with the plurality's conclusion that the policymaker inquiry is purely a question of state law.
See Gobel,
. Cal.Gov’t Code § 26605 provides that "[t]he sheriff shall take charge of and keep the county jail and the prisoners in it."
See also Brandt v. Board of Supervisors,
. In
Michenfelder,
we found that the standard announced by the Court in
Turner v. Safley,
. Thompson alleges that the strip search at the county jail included a visual inspection of his anal area. The County does not deny that the County strip search policy indeed calls for a body cavity inspection.
. We emphasize, however, that our decision is extremely narrow and only applies to theft of an automobile; we express no opinion on the validity of a blanket strip search policy as applied to arrestees charged with other crimes against property, whether they be classified as felonies or misdemeanors.
. A search that is in theory permissible in a particular context may in fact run afoul of the Fourth Amendment if conducted in an unnecessarily cruel, painful, or dangerous manner.
