    When it comes to speeding tickets and so-called “speed
    traps,” the Legislature has passed statutes that prove you can
    fight City Hall. As we decide in this appeal, however, neither
    those statutes nor any other legal theory permits civilly suing a
    city to recover monetary damages or other relief for speed traps—
    at least on the facts and theories of liability properly presented
    here.
    I. BACKGROUND
    A.    Background Law
    California’s basic speed law provides that “[n]o person shall
    drive a vehicle upon a highway at a speed greater than is
    reasonable or prudent . . . and in no event at a speed which
    endangers the safety of persons or property.” (Veh. Code,
    § 22350.)
    The Vehicle Code prohibits “peace officer[s] or other
    person[s]” from “us[ing] a speed trap in arresting . . . any person
    for any alleged violation of this code” and from using a speed trap
    “in securing evidence as to the speed of any vehicle for the
    purpose of an arrest or prosecution under this code.” (Veh. Code,
    § 40801.) The Vehicle Code defines “speed trap” to include a
    “section of a highway with a prima facie speed limit [provided or
    established in certain ways] if that prima facie speed limit is not
    justified by an engineering and traffic survey conducted within
    five years prior to the date of the alleged violation, and
    enforcement of the speed limit involves the use of radar or any
    other electronic device that measures the speed of moving
    objects.” (Veh. Code, § 40802, subd. (a)(2).)
    The Vehicle Code also specifies certain consequences when
    speed traps are used. Under Vehicle Code section 40803, no
    3
    evidence of a vehicle’s speed “shall be admitted in any court upon
    the trial of any person in any prosecution under this code upon a
    charge involving the speed of a vehicle when the evidence is
    based upon or obtained from or by the maintenance or use of a
    speedtrap.” Vehicle Code section 40804 makes “an officer or
    other person . . . incompetent as a witness if the testimony is
    based upon or obtained from or by the maintenance or use of a
    speed trap.” And Vehicle Code section 40805 states “[e]very court
    shall be without jurisdiction to render a judgment of conviction
    against any person for a violation of this code involving the speed
    of a vehicle if the court admits any evidence or testimony secured
    in violation of, or which is inadmissible under[,] this article.”
    B.     Plaintiffs and Appellants’ Speeding Tickets
    Plaintiffs and appellants Esther Kaminsky, James
    Cameron, Mark Shamoun, and Joseph McLaughlin were each
    cited for driving over a posted speed limit in the City. On March
    8, 2017, Shamoun was arrested and issued a citation for unsafe
    speed in violation of Vehicle Code section 22350 on Roscoe
    Boulevard near Sale Avenue. On November 17, 2017, Cameron
    was arrested and issued a citation for unsafe speed on Sepulveda
    Boulevard near Sardis Avenue. On April 2, 2018, Kaminsky and
    McLauglin were each separately arrested and issued citations for
    unsafe speed on Canoga Avenue near Strathern Street.1
    All four plaintiffs were informed by the respective police
    officers who arrested them that their speed had been detected by
    use of a laser device, and the citations they received similarly
    1
    The record does not identify the precise speed at which any
    of the plaintiffs were driving.
    4
    indicated a laser device was used in determining their speed. All
    four plaintiffs were released from custody only by signing an
    agreement to appear in court.
    McLaughlin chose not to contest his citation and paid $436
    in fines and fee assessments in June 2018, as well as a fee to
    attend traffic school. McLaughlin’s conviction on the citation
    charge was entered in October 2018.
    Shamoun, Cameron, and Kaminsky each retained counsel
    to represent them. Their citations were ultimately dismissed at
    trial because no valid traffic survey was in place at the time of
    the citation.2
    C.    Plaintiffs Civilly Sue the City
    Plaintiffs filed a putative class action complaint alleging
    nine causes of action against the City of Los Angeles and the City
    of Los Angeles’ Department of Transportation in July 2019.
    Generally speaking, the complaint alleged that in or around
    2008, the City began allowing its engineering and traffic surveys
    (traffic surveys) to expire on hundreds of miles of City streets and
    began conducting inadequate traffic surveys that did not meet
    the requirements of the Vehicle Code. As alleged, the City did
    not disclose that it was not complying with legislative
    prohibitions against speed traps to the public, instead concealing
    that fact while continuing to arrest motorists and issue them
    speeding citations at speed trap locations based on the use of
    2
    The record does not indisputably establish the reason for
    dismissal of Cameron’s citation, but Cameron contends this was
    the reason and the fact of dismissal is undisputed.
    5
    radar or laser devices. The complaint also alleged the City
    Council for the City began making efforts to update speed limits
    in 2018.
    After an initial demurrer, plaintiffs filed a first amended
    class action complaint (the operative complaint) in May 2020.
    The operative complaint alleged plaintiffs and the putative class
    members were each arrested and subjected to criminal
    prosecution by the issuance of a citation to appear in court by a
    Los Angeles Police Department officer for exceeding the posted
    speed limit. Plaintiffs contended the locations at which they were
    arrested and cited constituted unlawful “speed traps” because the
    posted speed limits were not justified by valid traffic surveys, and
    their speed was determined by use of a laser or radar device.
    According to the operative complaint, plaintiffs had a due
    process right to the disclosure of favorable or exculpatory
    evidence, including evidence that no valid traffic survey existed.
    Plaintiffs alleged the City had a self-executing obligation to
    disclose exculpatory information soon after the issuance of each
    citation, and the City did not make such disclosures within 30
    days prior to trial. Instead, in issuing and prosecuting speeding
    citations, the City impliedly represented it had complied with
    applicable laws and regulations and plaintiffs did not know of the
    traffic survey requirement and had no reason to suspect the City
    had a systematic practice of noncompliance.
    The operative complaint asserts nine causes of action,
    including, as pertinent here: violation of mandatory duties under
    Government Code section 815.6; negligence; a claim under
    Section 1983 for arrest and citation without probable cause; a
    claim under Section 1983 for violation of the due process right to
    disclosure of exculpatory material; a claim under Section 1983 for
    6
    violation of the due process right to not be criminally charged or
    prosecuted based on falsified evidence; violation of Article 1,
    sections 7 and 13 of the California Constitution; and violation of
    the Bane Act (Civil Code section 52.1).3 Broadly speaking, these
    various causes of action can be grouped to allege two theories of
    liability. First, plaintiffs contend the City, or its employees,
    breached duties in relation to plaintiffs’ arrests and citations in
    speed traps.4 Second, plaintiffs contend various of their
    constitutional rights had been violated by the use of the speed
    traps and by the course of events in plaintiffs’ respective
    prosecutions.5 Among the exhibits to the operative complaint
    3
    “The Bane Act makes it unlawful for any person to
    interfere by threat, intimidation, or coercion, or attempt to
    interfere by threats, intimidation, or coercion, with the exercise
    or enjoyment by any individual secured by the Constitution or
    laws of California.” (Murchison v. County of Tehama (2021) 
    69 Cal.App.5th 867
    , 896.)
    Plaintiffs also alleged causes of action for false arrest and
    negligent misrepresentation, but those are not the subject of any
    claim of error on appeal.
    4
    Plaintiffs’ cause of action for violation of mandatory duties
    alleges the City violated a mandatory duty to prevent the use of
    speed traps, and its cause of action for negligence alleged various
    City employees had a duty to use due care in performing their
    obligations related to speed traps, and breached those duties.
    5
    Plaintiffs alleged three claims under Section 1983
    predicated on alleged violations of a Fourth Amendment right to
    be secure against unreasonable seizure, a due process right to the
    disclosure of exculpatory evidence, and a due process right not to
    be charged based on false or fabricated evidence. Plaintiffs also
    alleged a claim under the California Constitution based on these
    same theories. Plaintiffs additionally alleged a violation of the
    7
    were excerpts from LADOT’s 2008 and 2014 databases
    identifying City streets with associated traffic surveys and their
    expiration dates.
    In terms of remedies sought, the operative complaint seeks
    compensatory, consequential, actual, and treble damages;
    restitution and disgorgement; preliminary and permanent
    injunctive relief; and attorney fees and costs of suit.
    D.    The City’s Demurrer
    The City demurred to the operative complaint, arguing it
    failed to state facts sufficient to state a cause of action. Among
    other arguments, the City contended the statutes prohibiting the
    use of speed traps imposed no mandatory duty on the City that
    would support civil liability and the use of the speed traps did not
    violate plaintiffs’ Fourth Amendment or due process rights.
    The City sought judicial notice of the traffic surveys for the
    locations at which plaintiffs had been cited and the notice of
    ruling for the trial court’s decision on the original demurrer. The
    survey for Canoga Avenue between Strathern Street and Ventura
    Boulevard (where Kaminsky and McLaughlin were cited in April
    2, 2018) was dated effective April 4, 2016. The survey for
    Sepulveda Boulevard between Ohio Avenue and Venice
    Boulevard (where Cameron was cited in November 17, 2017) was
    dated effective October 10, 2008 and an Addendum extended its
    expiration date to October 10, 2018. The survey for Roscoe
    Bane Act, which contended the City interfered with plaintiffs’
    exercise of their constitutional rights to be free from
    unreasonable arrest and prosecution, as well as their statutory
    rights not to be arrested and cited in violation of California’s
    speed trap prohibition.
    8
    Boulevard between Haskell Avenue and Valley Circle Boulevard
    (where Shamoun was cited on March 8, 2017) was dated effective
    March 19, 2012.
    Plaintiffs opposed the City’s demurrer. Plaintiffs’
    opposition included a single sentence requesting leave to amend
    if any cause of action was deemed insufficient. Plaintiffs also
    sought judicial notice of a portion of the California Manual on
    Uniform Traffic Control Devices, a minute order in another case
    involving Kaminsky, and a judgement entered in a case involving
    someone who was not a named plaintiff.6
    E.    The Trial Court’s Ruling
    The trial court sustained the City’s objection to plaintiffs’
    request for judicial notice of the unrelated judgment and
    otherwise granted the parties’ requests for judicial notice. The
    trial court then sustained the demurrer in its entirety without
    leave to amend.
    As to the first cause of action for breach of mandatory
    duties, the trial court found the speed trap statutes passed by the
    Legislature did not impose mandatory duties upon the City to
    prevent the use of speed traps. As to the second cause of action
    for negligence, the court found plaintiffs had not sufficiently
    alleged the City violated any mandatory or discretionary duties
    and City employees were in any event immune from the alleged
    liability. As to the third cause of action for unreasonable seizure
    in violation of Section 1983, the court found plaintiffs had not
    alleged a violation of their Fourth Amendment rights because
    6
    The City objected to the request to judicially notice the
    judgment on the ground that it was irrelevant.
    9
    excessive speed provides probable cause for a stop. As to the fifth
    cause of action for failure to disclose exculpatory material in
    violation of Section 1983, the court found there was no authority
    that requires a police officer to know or disclose the validity of a
    traffic survey during a traffic stop or that requires the City to
    disclose information regarding the validity of the traffic surveys
    before trial. (The court also observed that requiring police
    officers to disclose invalid traffic surveys at the time of citation
    would defeat the purpose of issuing citations.) As to the sixth
    cause of action for violation of the right not to be criminally
    charged based on falsified evidence under Section 1983, the court
    found the operative complaint did not allege the City or its
    employees deliberately fabricated evidence that plaintiffs were
    exceeding the posted speed limit, and the traffic surveys were
    deemed invalid not because they were fabricated, but because
    they were no longer up to date. Plaintiffs’ derivative seventh
    cause of action for violation of the California Constitution failed
    to state a claim for the same reason the federal constitutional
    claims failed. And as to the eighth cause of action for violation of
    the Bane Act, the court found plaintiffs did not state a claim
    because all of their other theories of liability failed and there was
    no sufficient allegation of coercion beyond that inherent in any
    arrest.
    The trial court denied leave to amend, stating it allowed
    Plaintiffs leave to amend after the original demurrer and the
    First Amended Complaint still did not state viable causes of
    action.
    10
    II. DISCUSSION
    The trial court’s ruling is correct. The Legislature has
    prohibited the use of speed traps, but the statutory language
    indicates it has not imposed mandatory duties on municipalities
    like the City to ensure compliance with that prohibition (as
    opposed to the aforementioned remedy of suppression for anyone
    cited as part of a speed trap). Speed trap citations also do not
    constitute constitutional violations, at least on the facts alleged
    in the operative complaint: Police officers who stop motorists
    driving over the posted speed limit have probable cause to stop
    them; disclosure of traffic surveys in traffic court rather than
    prior to trial does not constitute a due process violation; and
    plaintiffs have not alleged any evidence was actually fabricated
    in support of their falsification of evidence claim. Finally, the
    City employees mentioned in the operative complaint are
    immune from liability for their asserted negligence under the
    alleged circumstances described in the complaint.
    A.    Standard of Review
    We review an order sustaining a demurrer without leave to
    amend de novo. (Centinela Freeman Emergency Medical
    Associates v. Health Net of California, Inc. (2016) 
    1 Cal.5th 994
    ,
    1010; Morales v. 22nd Dist. Agricultural Assn. (2016) 
    1 Cal.App.5th 504
    , 537.) “[W]e accept the truth of material facts
    properly pleaded in the operative complaint, but not contentions,
    deductions, or conclusions of fact or law. We may also consider
    matters subject to judicial notice. (Evans v. City of Berkeley
    (2006) 
    38 Cal.4th 1
    , 6[ (Evans)].)” (Yvanova v. New Century
    Mortgage Corp, 
    62 Cal.4th 919
    , 924, fn. omitted.) “‘[T]he plaintiff
    has the burden of showing that the facts pleaded are sufficient to
    11
    establish every element of the cause of action and overcoming all
    of the legal grounds on which the trial court sustained the
    demurrer, and if the defendant negates any essential element, we
    will affirm the order sustaining the demurrer as to the cause of
    action.’” (Rossberg v. Bank of America, N.A. (2013) 
    219 Cal.App.4th 1481
    , 1490-1491 (Rossberg).)
    B.     Mandatory Duty Claim
    Government Code section 815.6 states that “[w]here a
    public entity is under a mandatory duty imposed by an
    enactment that is designed to protect against the risk of a
    particular kind of injury, the public entity is liable for an injury
    of that kind proximately caused by its failure to discharge the
    duty unless the public entity establishes that it exercised
    reasonable diligence to discharge the duty.” Thus, in
    determining whether liability for breach of a mandatory duty
    may be imposed on a public entity under this statute, California
    courts consider (1) whether an enactment imposed a mandatory
    duty; (2) whether the enactment intended to protect against the
    kind of risk of injury suffered by the plaintiff; and (3) whether
    breach of the mandatory duty was a proximate cause of the injury
    suffered. (Department of Corporations v. Superior Court (2007)
    
    153 Cal.App.4th 916
    , 926.) “[A]pplication of section 815.6
    requires that the enactment at issue be obligatory, rather than
    merely discretionary or permissive, in its directions to the public
    entity; it must require, rather than merely authorize or permit,
    that a particular action be taken or not taken.” (Haggis v. City of
    Los Angeles (2000) 
    22 Cal.4th 490
    , 498.)
    “Courts have construed this [obligatory enactment
    requirement] rather strictly, finding a mandatory duty only if the
    12
    enactment ‘affirmatively imposes the duty and provides
    implementing guidelines.’ [Citations.]” (Guzman v. County of
    Monterey (2009) 
    46 Cal.4th 887
    , 898 (Guzman); see also Rey v.
    Madera Unified School Dist. (2012) 
    203 Cal.App.4th 1223
    , 1234.)
    The enactment cannot “simply set forth a prohibition or a right,
    as opposed to an affirmative duty on the part of a government
    agency to perform some act.” (Clausing v. San Francisco Unified
    School Dist. (1990) 
    221 Cal.App.3d 1224
    , 1239 (Clausing).)
    Instead, “to impose a mandatory duty on a public entity (see Gov.
    Code, § 815.6), ‘“the mandatory nature of the duty must be
    phrased in explicit and forceful language”’ [citation], and the
    statute ‘must impose a duty on the specific public entity sought to
    be held liable’ [citation].” (Guzman, 
    supra, at 894
    .)
    Plaintiffs’ appellate briefing focuses on one provision of the
    Vehicle Code in arguing its allegation of the existence of a
    mandatory duty should have survived the City’s demurrer:
    Vehicle Code section 40801.7 That statute provides: “No peace
    officer or other person shall use a speed trap in arresting, or
    participating or assisting in the arrest of, any person for any
    alleged violation of this code nor shall any speed trap be used in
    securing evidence as to the speed of any vehicle for the purpose of
    an arrest or prosecution under this code.” By its plain terms,
    section 40801 prohibits peace officers and other persons from
    using speed traps in certain circumstances. It does not impose
    any duties, mandatory or otherwise, on the City or LADOT, and
    7
    The other Vehicle Code sections cited in plaintiffs’
    mandatory duty cause of action define the terms “engineering
    and traffic survey” and “speed trap.” (Veh. Code, §§ 627, 40802.)
    13
    the statute does not provide for any guidelines to implement a
    purported mandatory duty.
    Our interpretation of Vehicle Code section 40801 to impose
    no mandatory duty on local governments is underscored by the
    adjacent sections of the Vehicle Code, which specify the
    consequences for a violation of the rule against speed trap usage
    in prosecutions under the Vehicle Code involving a vehicle’s
    speed. These too do not promulgate implementing guidelines
    that might suggest the imposition of a mandatory duty. Section
    40803, for example, provides that evidence of the speed of a
    vehicle obtained using a speed trap is inadmissible. Section
    40804 similarly provides that an officer or other person is
    incompetent as a witness if their testimony is based on or
    obtained from the use of a speed trap. And section 40805
    provides that courts are without jurisdiction to render convictions
    if the court admits any evidence or testimony secured in violation
    of the speed trap law. While these sections obviously establish
    there are consequences for use of an improper speed trap, none
    outlaws the existence of speed traps, provides guidance regarding
    how any such assumed prohibition should be carried out, or
    states any consequences for the failure to do so. That all
    militates in favor of a conclusion that no mandatory duty is
    imposed. (See, e.g., Clausing, supra, 221 Cal.App.3d at 1239
    [Education Code sections that expressly prohibited teachers from
    using corporal punishment but did not set forth guidelines or
    rules for preventing it did not create mandatory duties on the
    part of schools and districts to ensure students were never
    subjected to corporal punishment by teachers].)
    In arguing the contrary, plaintiffs assert that a prohibitory
    statute still can create a mandatory duty. Even if that is true as
    14
    a general matter, it still does not change what we have already
    seen in examining the pertinent Vehicle Code sections that are at
    issue in this case: none include language from which the
    existence of a mandatory duty can be inferred. Plaintiffs also
    argue holding Vehicle Code section 40801 imposes no mandatory
    duty would be inconsistent with the purpose of the statute and
    the case law interpreting it because the statute does not allow for
    the exercise of any discretion in the use of speed traps. While it
    is true that the inclusion of discretionary language in a statute
    can be probative of whether it imposes a mandatory duty, the
    absence of such language is not determinative—and here, there
    are good indications apart from the question of authorized
    discretion that the Legislature intended to create no mandatory
    duty. Plaintiffs finally contend on the issue of mandatory duty
    that Vehicle Code section 627 imposes its own mandatory duty by
    requiring traffic surveys to include consideration of prevailing
    speeds, accident records, and conditions not readily apparent to a
    driver. Assuming without deciding that Vehicle Code section 627
    does, in fact, impose some mandatory duty, that duty is to ensure
    roadways reflect safe driving conditions. It is not a duty to
    protect plaintiffs from being stopped for traffic violations using
    speed traps, or to authorize recovery of alleged damages for use of
    speed traps.
    C.     Constitutional Claims
    1.    Background legal principles
    Section 1983 provides in relevant part: “Every person who,
    under color of any statute, ordinance, regulation, custom, or
    usage, of any State . . . subjects, or causes to be subjected, any
    citizen of the United States or other person within the
    15
    jurisdiction thereof to the deprivation of any rights, privileges, or
    immunities secured by the Constitution and laws, shall be liable
    to the party injured in an action at law, suit in equity, or other
    proper proceeding for redress . . . .” “‘To state a claim under
    [Section] 1983, a plaintiff must allege the violation of a right
    secured by the Constitution and laws of the United States, and
    must show that the alleged deprivation was committed by a
    person acting under color of state law.’ [Citation.]” (Arce v.
    Childrens Hospital Los Angeles (2012) 
    211 Cal.App.4th 1455
    ,
    1472 (Arce).)
    “In regards to plaintiffs’ [S]ection 1983 claim, we ‘“apply
    federal law to determine whether [the] complaint [has pleaded] a
    cause of action . . . sufficient to survive a general demurrer.”
    [Citations.] According to federal law, “we are required to
    construe complaints under [Section 1983] liberally.” [Citation.]
    “To uphold a dismissal [for failure to state a claim for relief, the
    federal counterpart of our general demurrer], it must appear to a
    certainty that the plaintiff would not be entitled to relief under
    any set of facts that could be proved.” [Citation.]’ [Citation.]”
    (Arce, supra, 211 Cal.App.4th at 1471.) “In line with California
    practice, the court accepts the allegations in the complaint as
    true and construes the allegations, and any reasonable inferences
    that may be drawn from them, in the light most favorable to the
    plaintiff.” (Ibid.)
    2.     Fourth Amendment Section 1983 claim
    The Fourth Amendment protects “[t]he right of the people
    to be secure in their persons, houses, papers, and effects, against
    unreasonable searches and seizures . . . .” (U.S. Const., 4th
    Amend.) “A traffic stop for a suspected violation of law is a
    16
    ‘seizure’ of the occupants of the vehicle and therefore must be
    conducted in accordance with the Fourth Amendment.
    [Citation.] . . . [T]o justify this type of seizure, officers need only
    ‘reasonable suspicion’—that is, ‘a particularized and objective
    basis for suspecting the particular person stopped’ of breaking
    the law.” (Heien v. North Carolina (2014) 
    574 U.S. 54
    , 60.)
    In their cause of action under Section 1983 alleging a
    Fourth Amendment violation, plaintiffs argue there was no
    proper basis for their arrest and citation because both resulted
    from use of a radar device at a location where no valid traffic
    survey was in place. The problem with this argument, however,
    is that the existence of a valid traffic survey does not defeat the
    officers’ reasonable conclusion at the time of the stop that
    plaintiffs were exceeding the posted speed limit.8 Indeed, “it is
    beyond contravention that excessive speed, whether detected
    through mechanical device or observation, provides probable
    cause for a stop.” (People v. Sullivan (1991) 
    234 Cal.App.3d 56
    ,
    65 (Sullivan); see also People v. Hardacre (2004) 
    116 Cal.App.4th 1292
    , 1300 [“[a] law enforcement officer may legally stop a
    motorist if the facts and circumstances known to the officer
    support a reasonable suspicion that the driver has violated the
    Vehicle Code or some other law”]; San Joaquin Deputy Sheriffs’
    Ass’n v. County of San Joaquin (E.D.Cal. 2012) 
    898 F.Supp.2d 8
    Plaintiffs argue their allegations that the police officers
    knew the surveys were invalid renders these principles
    inapposite. This is unpersuasive here, where the relevant traffic
    surveys—which were judicially noticed—all appear facially
    timely (e.g., dated within the five-year period prescribed by
    Vehicle Code section 40802) and thus valid based on the dates of
    plaintiffs’ citations.
    17
    1177, 1186 [speeding is a vehicular violation that gives an officer
    probable cause to stop a driver].) The Fourth Amendment
    Section 1983 claim therefore fails as a matter of law.9
    Plaintiffs’ claim also fails for another independent reason:
    “the prohibition against speed traps is strictly statutory”
    (Sullivan, supra, 234 Cal.App.3d at 65) and “[a] violation of state
    law does not itself suffice to show [defendants] violated
    [plaintiffs’] federal constitutional rights.” (Wagda v. Town of
    Danville (N.D.Cal. Oct. 24, 2016, No. 16-cv-00488-MMC) 2016
    U.S.Dist.LEXIS 147108, at *38-39, fn. 19 [claim that traffic stop
    for speeding in speed trap violated Fourth Amendment rights
    failed because plaintiff did not allege officer lacked reasonable
    suspicion to stop motorist for speeding].)
    Plaintiffs additionally argue they sufficiently stated a claim
    under Monell v. New York City Dept. of Social Services (1978) 
    436 U.S. 658
     (Monell). In Monell, the U.S. Supreme Court held that
    “Section 1983 does not assign liability to a local government
    under a respondeat superior theory, but the entity may be liable
    if the constitutional violation was caused by its official policy,
    practice, or custom.” (Kerkeles v. City of San Jose (2011) 
    199 Cal.App.4th 1001
    , 1015-1016.) To sustain a Section 1983 claim
    under Monell, “a plaintiff must show that (1) he or she possessed
    a constitutional right of which he or she was deprived; (2) that
    the municipality had a policy which amounted to ‘deliberate
    indifference’ to the plaintiff's constitutional right; and (3) that
    9
    Insofar as Plaintiffs allege a legal conclusion—that there
    was no probable cause for stopping them—the conclusory
    allegation is properly disregarded. (Evans, supra, 
    38 Cal.4th at 6
    .)
    18
    action pursuant to that policy caused a violation of that
    constitutional right.” (Zuniga v. Housing Authority (1995) 
    41 Cal.App.4th 82
    , 103-104 (Zuniga).) Because we conclude
    plaintiffs have not sufficiently alleged they were deprived of a
    constitutional right, their associated Monell claim also fails.
    3.      Section 1983 claim based on violation of due
    process right to disclosure of favorable evidence
    “The prosecution has a duty under the Fourteenth
    Amendment’s due process clause to disclose evidence to a
    criminal defendant . . . [¶] . . . [that is] both favorable to the
    defendant and material on either guilt or punishment.
    [Citation.]” (In re Sassounian (1995) 
    9 Cal.4th 535
    , 543-544, fn.
    omitted; see also Brady v. Maryland (1963) 
    373 U.S. 83
    , 87
    (Brady).) “In Brady, the United States Supreme Court held ‘that
    the suppression by the prosecution of evidence favorable to an
    accused upon request violates due process where the evidence is
    material either to guilt or to punishment, irrespective of the good
    faith or bad faith of the prosecution.’ [Citation.]” (People v.
    Salazar (2005) 
    35 Cal.4th 1031
    , 1042.) “[E]vidence that is
    presented at trial is not considered suppressed, regardless of
    whether or not it had previously been disclosed during discovery.
    [Citations.]” (People v. Morrison (2004) 
    34 Cal.4th 698
    , 715.) We
    will assume for purposes of analysis in this case that material
    exculpatory information must be disclosed to a defendant before
    he or she pleads guilty or no contest. (See, e.g., Smith v. Baldwin
    (9th Cir. 2007) 
    510 F.3d 1127
    , 1148; but see United States v. Ruiz
    (2002) 
    536 U.S. 622
    .)
    None of the plaintiffs have properly alleged a procedural or
    substantive due process violation. Plaintiffs Kaminsky,
    19
    Shamoun, and Cameron appeared at trial, at which point
    evidence regarding the relevant traffic surveys was produced.
    They have not alleged the timing of the disclosure prejudiced the
    outcome of their trials. Nor could they, as they all had their
    citations dismissed based on the inadequacy of the relevant
    traffic surveys. As to plaintiff McLaughlin, the operative
    complaint does not allege McLaughlin would have gone to trial,
    and thus had his citation dismissed, if he had received evidence
    regarding the traffic survey in place at the location at which he
    was cited.
    Plaintiffs’ related contention that Penal Code section
    1054.7’s instruction that discovery disclosures be made at least
    30 days prior to trial was violated similarly does not demonstrate
    a due process violation. A defendant’s due process right to
    disclosure “is independent of, and thus not impaired or affected
    by, the criminal discovery statutes.” (Bridgeforth v. Superior
    Court (2013) 
    214 Cal.App.4th 1074
    , 1081; see also Izazaga v.
    Superior Court (1991) 
    54 Cal.3d 356
    , 378 [“The prosecutor’s
    duties of disclosure under the due process clause are wholly
    independent of any statutory scheme of reciprocal discovery”].)
    4.   Fabrication of evidence
    As plaintiffs explain, they assert a claim for deliberate
    fabrication of evidence, as recognized by the Ninth Circuit in
    Devereaux v. Abbey (9th Cir. 2001) 
    263 F.3d 1070
    , 1076
    (Devereaux). “A Devereaux claim is a claim that the government
    violated the plaintiff’s due process rights by subjecting the
    plaintiff to criminal charges based on deliberately-fabricated
    evidence. [Citation.] Fundamentally, the plaintiff must first
    point to evidence he contends the government deliberately
    20
    fabricated. [Citations.] [¶] Then, there are two ‘circumstantial
    methods’ of proving that the falsification was deliberate.
    [Citation.] The first method is to demonstrate that the defendant
    continued his investigation of the plaintiff even though he knew
    or should have known that the plaintiff was innocent. [Citation.]
    The second method is to demonstrate that the defendant used
    ‘investigative techniques that were so coercive and abusive that
    [he] knew or should have known that those techniques would
    yield false information.’ [Citation.] These methods are not
    themselves independent causes of action. Rather, they are
    methods of proving one element—intent—of a claim that the
    government deliberately fabricated the evidence at issue.”
    (Bradford v. Scherschligt (9th Cir. 2015) 
    803 F.3d 382
    , 386.)
    Plaintiffs’ operative complaint did not identify any evidence
    allegedly fabricated by the City. As a result, their claim for
    fabrication of evidence necessarily fails. Spencer v. Peters (9th
    Cir. 2017) 
    857 F.3d 789
    , 799, upon which plaintiffs rely in
    attempting to argue the contrary, does not hold a plaintiff need
    not identify evidence that was fabricated in order to state a
    named fabrication of evidence claim. Rather, it explains ways in
    which a plaintiff may prove evidence was fabricated in the
    absence of direct evidence.
    5.     Claims under the California Constitution
    California has generally adopted Fourth Amendment
    jurisprudence for interpreting analogous provisions of the
    California Constitution. (People v. Perry (2019) 
    36 Cal.App.5th 444
    , 466; see also People v. Buza (2018) 
    4 Cal.5th 658
    , 685-686.)
    Accordingly, because we concluded plaintiffs did not state a claim
    21
    under the Fourth Amendment, they have not stated a claim
    under the California Constitution.
    Similarly, “[b]oth the federal and state Constitutions
    compel the government to afford persons due process before
    depriving them of any property interest. [Citations.] In light of
    the virtually identical language of the federal and state
    guarantees, [the California Supreme Court has] looked to the
    United States Supreme Court’s precedents for guidance in
    interpreting the contours of our own due process clause and have
    treated the state clause’s prescriptions as substantially
    overlapping those of the federal Constitution.” (Today’s Fresh
    Start, Inc. v. Los Angeles County Office of Education (2013) 
    57 Cal.4th 197
    , 212.) Because we conclude plaintiffs did not state
    claims under the federal due process clause, we likewise conclude
    the California Constitution-based claims also fail as a matter of
    law.
    D.    Bane Act
    As explained earlier in the margin, the Bane Act prohibits
    interfering with rights guaranteed by the California Constitution
    or state law. “The essence of a Bane Act claim is that the
    defendant, by the specified improper means (i.e., ‘threats,
    intimidation or coercion’), tried to or did prevent the plaintiff
    from doing something he or she had the right to do under the law
    or to force the plaintiff to do something that he or she was not
    required to do under the law.” (Austin B. v. Escondido Union
    School Dist. (2007) 
    149 Cal.App.4th 860
    , 883.)
    “There are two distinct elements for a [Bane Act] cause of
    action. A plaintiff must show (1) intentional interference or
    attempted interference with a state or federal constitutional or
    22
    legal right, and (2) the interference or attempted interference was
    by threats, intimidation or coercion.” (Allen v. City of Sacramento
    (2015) 
    234 Cal.App.4th 41
    , 67.) Case law articulates two theories
    of coercion sufficient to support a Bane Act claim. “The first
    theory of coercion is that a violation of the Bane Act requires a
    showing of coercion independent from the coercion inherent in
    the constitutional violation itself. (Shoyoye v. County of Los
    Angeles (2012) 
    203 Cal.App.4th 947
    , 959 [ ] (Shoyoye).)” (County
    Inmate Telephone Service Cases (2020) 
    48 Cal.App.5th 354
    , 369.)
    “The second analysis appears in Cornell v. City and County of
    San Francisco (2017) 
    17 Cal.App.5th 766
     [ ] (Cornell). Cornell
    held that, ‘where an unlawful arrest is properly pleaded and
    proved, the “threat, intimidation or coercion” element of section
    52.1 . . . requires a specific intent to violate protected rights.’ (Id.
    at p. 799, italics & capitalization omitted; 
    ibid.
     [ ].)” (County
    Inmate Telephone Service Cases, supra, 48 Cal.App.5th at 369.)
    As already discussed, plaintiffs have not sufficiently pled
    the City violated any of their constitutional rights or any
    mandatory statutory duty. Plaintiffs therefore also fail to allege
    facts sufficient to establish the first prong of a Bane Act cause of
    action. Moreover, even if they had, they also failed to allege the
    requisite interference. There is no allegation of threat or
    intimidation in the complaint, and their allegations do not state a
    claim under either possible theory of coercion. Plaintiffs alleged
    no coercion independent of the arrests that would satisfy the
    Shoyoye theory of coercion, and even if we assumed an unlawful
    arrest was pleaded such that the Cornell theory of coercion might
    apply, plaintiffs did not plead defendants had a specific intent to
    violate their constitutional rights.
    23
    E.    Negligence
    The operative complaint alleges the City is vicariously
    liable under Government Code section 815.2 for the acts or
    omissions of City employees. Section 815.2 provides that “[a]
    public entity is liable for injury proximately caused by an act or
    omission of an employee of the public entity within the scope of
    his employment if the act or omission would, apart from this
    section, have given rise to a cause of action against that employee
    or his personal representative.” (Gov. Code, § 815.2, subd. (a).) It
    further provides that “[e]xcept as otherwise provided by statute, a
    public entity is not liable for an injury resulting from an act or
    omission of an employee of the public entity where the employee
    is immune from liability.” (§ 815.2, subd. (b).) Thus, “in a cause
    of action for negligence, the existence and extent of an entity’s
    vicarious liability under [section 815.2, subdivision (a)], will be
    determined by the scope of duty legally attributed to its
    employees.” (Torsiello v. Oakland Unified School Dist. (1987) 
    197 Cal.App.3d 41
    , 45.)
    “Except as otherwise provided by statute (including Section
    820.2), a public employee is liable for injury caused by his act or
    omission to the same extent as a private person.” (Gov. Code,
    § 820.) Plaintiffs’ negligence cause of action identifies three
    categories of City employees that plaintiffs allege acted
    negligently: (1) “members of its City Council who enacted the
    relevant speed limits;” (2) “traffic engineers, managers and other
    employees of LADOT tasked with producing and maintaining
    valid ETSes and setting lawful speed limits;” and (3) “LAPD
    officers assigned to use radar and laser devices to enforce the
    basic speed law on City streets and prosecute alleged violations of
    the same.”
    24
    As alleged, the employees—and thus the City—are immune
    from negligence liability. The allegation that City Council
    members were negligent in enacting speed limits implicates the
    City Council’s authority under Vehicle Code section 22358, which
    provides a local authority “may by ordinance determine and
    declare a prima facie speed limit” where it determines, based on
    an engineering and traffic survey, that the speed limit of 65 miles
    per hour is unsafe. (Veh. Code, § 22358.) As Vehicle Code section
    22358 does not require a local authority to set a lower speed
    limit, its decision to do so is an act of discretion that falls within
    the immunity provisions of Government Code section 820.2.10
    (Gov. Code, § 820.2 [“Except as otherwise provided by statute, a
    public employee is not liable for an injury resulting from his act
    or omission where the act or omission was the result of the
    exercise of the discretion vested in him, whether or not such
    10
    Plaintiffs argue that Government Code section 820.2
    cannot apply to the allegations in the complaint because
    government employees are only immune for “basic policy
    decisions” and not operational or ministerial decisions that
    merely implement a basic policy decision. (Johnson v. State of
    California (1968) 
    69 Cal.2d 782
    , 796.) While this can prevent the
    issue of immunity from being determined at the demurrer stage,
    that is not the case here where the allegations of the complaint
    suffice to establish the acts in question were, in fact,
    discretionary rather than ministerial or operational. (Compare
    Zuniga, supra, 41 Cal.App.4th at 99 [immunity could not be
    determined on demurrer] with Caldwell v. Montoya (1995) 
    10 Cal.4th 972
    , 976 [affirming trial court’s order sustaining
    demurrer in part on immunity grounds]; Posey v. California
    (1986) 
    180 Cal.App.3d 836
     [same].)
    25
    discretion be abused”].) The allegation that the arresting officers
    were negligent for arresting and citing plaintiffs also implicates
    section 820.2 immunity. Plaintiffs were ticketed by police officers
    acting within the scope of their employment and whether the
    citations for unsafe speed should have been issued is a question
    within the officers’ discretion. Finally, despite plaintiffs’
    protestations to the contrary, their allegations against the City
    employees, and in particular their allegations that the engineers
    failed to comply with their statutory duties, is in essence a claim
    that they failed to enforce the speed trap laws. As we have held
    there was no mandatory duty to do so, those allegations fall
    within the immunity provided by Government Code section 821.
    (Gov. Code, § 821 [“A public employee is not liable for an injury
    caused . . . by his failure to enforce an enactment.”].)
    F.     Leave to Amend
    A plaintiff who suffers dismissal after a demurrer is
    sustained without leave to amend may make a showing of how
    the pleading may be cured by amendment for the first time on
    appeal. (See, e.g., Cansino v. Bank of America (2014) 
    224 Cal.App.4th 1462
    , 1468.) “‘The plaintiff bears the burden of
    proving there is a reasonable possibility of amendment.
    [Citation.] . . . [¶] To satisfy that burden on appeal, a plaintiff
    “must show in what manner he can amend his complaint and
    how that amendment will change the legal effect of his pleading.”
    [Citation.] The assertion of an abstract right to amend does not
    satisfy this burden. [Citation.] The plaintiff must clearly and
    specifically set forth the “applicable substantive law” [citation]
    and the legal basis for amendment, i.e., the elements of the cause
    of action and authority for it. Further, the plaintiff must set
    26
    forth factual allegations that sufficiently state all required
    elements of that cause of action. [Citations.] Allegations must be
    factual and specific, not vague or conclusionary. [Citation.]’”
    (Rossberg, supra, 219 Cal.App.4th at 1491; Rakestraw v.
    California Physicians’ Service (2000) 
    81 Cal.App.4th 39
    , 43-44;
    see also Cantu v. Resolution Trust Corp. (1992) 
    4 Cal.App.4th 857
    , 890 [to meet burden for leave to amend, “plaintiff must
    submit a proposed amended complaint or, on appeal, enumerate
    the facts and demonstrate how those facts establish a cause of
    action”].)
    In their opening brief, plaintiffs make several conclusory
    representations, mostly in footnotes, that they could amend their
    complaint to allege new causes of action. Then, in their reply
    brief, plaintiffs asserted they could amend “to sue as taxpayers to
    enjoin and restrain the City from illegally arresting and
    prosecuting drivers where it is clearly prohibited.” They also
    assert leave to amend should be granted to the extent necessary
    to “allege that Plaintiffs have a due process right not to be
    arrested and prosecuted through speed trap evidence under
    Vehicle Code Section 40801 without due process, and the City
    deprived Plaintiff[s] of that right without due process” or to bring
    a malicious prosecution claim.
    Plaintiffs’ assertions are insufficient to satisfy the
    requirement that a plaintiff must set forth the elements of the
    causes of action and authority for the claim and set forth factual
    allegations that sufficiently state all required elements of the
    causes of action. Plaintiffs’ piecemeal assertions that they could,
    if necessary, amend to allege new claims and their specific
    argument as to a single element of one new cause of action does
    27
    not demonstrate the trial court abused its discretion in denying
    leave to amend.
    DISPOSITION
    The judgment is affirmed. Defendants shall recover their
    costs on appeal.
