OPINION
Plaintiff-Appellant AE, a minor, was sexually assaulted by his seventeen-year-old foster brother (Foster Brother) while living in a foster family home in Tulare County, California. AE contends that the County of Tulare (County) and its employee social workers (collectively, Defendants), failed to intervene prior to his sexual assault, despite their knowledge of the escalating threats and violence against him. AE brought a federal civil rights claim pursuant to 42 U.S.C. § 1983 and state negligence claims against Defendants. AE appeals the district court’s dismissal with prejudice of all claims against the County. We conclude that the district court abused its discretion in dismissing AE’s § 1988 and derivative liability claims without leave to amend. Accordingly, we reverse the district court’s decision and vacate the judgment.
I. BACKGROUND
A. Factual Allegations of the First Amended Complaint
The First Amended Complaint tells a tragic story of escalating threats and violence against AE, a nine-year-old boy, at the hands of his Foster Brother. In September, 2008, AE was removed from his mother’s custody, 1 transferred to a foster family agency, and ultimately placed with foster care parents. According to the First Amended Complaint, Defendants knew or should have known that the Foster Brother, who was on probation, a dependent of the court, and on the caseload of a County social worker, 2 “was dangerous and posed a threat to [AE] and/or minors such as [AE].”
On November 5, 2008, a “reporting party” informed Yadira Portillo (Portillo) and Courtney Wampler (Wampler), both County social workers, that the Foster Brother hit AE in the chest and left “a 3/6 by 5 inch bruise on his left shoulder.” That same date, AE informed “CWA Felix” (Felix), also a County social worker, that two weeks earlier his Foster Brother had “socked him in the face and threatened him” after AE had witnessed the Foster Brother stealing money from their foster parent. Portillo and Wampler photographed AE’s bruise. Around the same time, the foster parent informed Portillo and Wampler that the Foster Brother was on probation and was a dependent of the court. Further, the foster parent reported that on November 4, 2008, the Foster Brother had cursed at her for wiggling the bathroom door knob, believing she was AE.
On November 20, 2008, AE’s mother expressed concerns to Felix regarding AE’s foster home placement. AE’s mother requested that Felix have AE moved to a different foster home.
On November 25, 2008, Dr. Soto called Prudence Morris, the “Team Leader” for *635 AE’s foster care, to report that AE had told him during a recent evaluation that the Foster Brother regularly entered the bathroom while AE was showering, using the toilet, or brushing his teeth, to tell AE to “hurry up, and curse [him].” AE also informed Portillo and Wampler directly that his Foster Brother “would unlock the bathroom door using his nail and threaten[ ] to ‘kick [AE’s] ass.” AE told Portillo and Wampler that his foster parent knew of the Foster Brother’s behavior, but had responded only by ordering AE to use a different bathroom.
On November 26, 2008, Portillo spoke with AE’s therapist, Adrian Marquez, regarding what she had learned of AE’s placement. Marquez responded that “there was a need to place more responsibility on the foster mother in supervising the actions of the children in the home ... [and] that he did not believe [AE] had been making allegations to seek attention, but was instead minimizing the behavior of [his Foster Brother].”
On December 10, 2008, AE’s foster parents reported to Portillo that AE had told them, approximately five days earlier, on December 5 or 6, that the Foster Brother “went into [AE’s] bedroom and attempted to get into his bed and pull his pants down.”
On December 12, 2008, Portillo received two telephone calls regarding AE. A man describing himself as AE’s uncle called to ask “what the agency was doing with his nephew.” A County deputy sheriff also called to report that a man purporting to be AE’s uncle had informed the police that “the agency was covering up an incident that occurred with his nephew and he wanted the Sheriff to pick up [AE] from foster care.”
That same day, Portillo contacted AE’s mother, who told Portillo that she had requested that Felix remove AE from his current placement. Subsequently, Portillo and another social worker, joined by a County police officer, interviewed AE. AE told the police officer “that he had been sodomized and forced to do oral copulation by [his Foster Brother].”
“On or about December 12 and/or 15, 2008,” Portillo informed AE’s mother that AE “had been assaulted, battered, sexually abused, sodomized and orally copulated by another dependent at the foster home ...”
On approximately December 15, 2008, Portillo, a deputy district attorney, a County police detective, and a forensic interview specialist interviewed AE. AE described the sexual assault in detail. Following this interview, Portillo met immediately with her supervisor to reassess AE’s foster placement, and AE was moved to a different foster home.
AE alleged that at all relevant times, Portillo, Wampler, and Felix were County employees acting within the course and scope of their employment. AE further alleged that all Defendants performed their acts and omissions “under the ordinances, regulations, customs, and practices of Defendant COUNTY OF TULARE
B. Procedural Background
The First Amended Complaint alleged two causes of action relevant to this appeal, a claim under 42 U.S.C. § 1983 for deliberate indifference, and claims for negligence pursuant to California statutes. 3
Defendants moved to dismiss pursuant to Federal Rule of Civil Procedure *636 (FRCP) 12(b)(6). The district court granted AE leave to amend the claims against Portillo, Wampler, and Felix. The district court dismissed with prejudice all claims against the County and entered judgment in its favor pursuant to FRCP 54(b). AE filed a timely appeal.
II. STANDARD OF REVIEW
We review
de novo
the district court’s dismissal of a complaint for failure to state a claim.
See Telesaurus VPC, LLC v. Power;
We review for abuse of discretion the district court’s denial of leave to amend.
See Telesaurus,
III. DISCUSSION
A. Section 1983 Claim
AE alleged claims against the County and individual County officials pursuant to 42 U.S.C. § 1983 for violations of the Due Process Clause of the Fourteenth Amendment, which “protects a foster child’s liberty interest in social worker supervision and protection from harm inflicted by a foster parent.”
Tamas v. Dep’t of Soc. & Health Sens.,
Section 1983 suits against local governments alleging constitutional rights violations by government officials cannot rely solely on respondeat superior liability.
See Whitaker v. Garcetti,
In the past, our cases have not required parties to provide much detail at the pleading stage regarding such a policy or custom. “In this circuit, a claim of municipal liability under § 1983 is sufficient to withstand a motion to dismiss even if the claim is based on nothing more than a bare allegation that the individual officers’ conduct conformed to official policy, custom, or practice.” Id. (citation, alteration, and internal quotation marks omitted).
AE contends that the First Amended Complaint met this minimalist standard, as it alleged that all Defendants performed *637 all acts and omissions regarding AE’s foster care placement and supervision “under the ordinances, regulations, customs, and practices of Defendant COUNTY OF TULARE ...”
Citing
Monell
and
City of Canton v. Harris,
Our circuit precedent, articulated first in
Shah v. County of Los Angeles,
Yet briefing on this appeal was completed before our decision in
Starr v. Baca,
whatever the difference between [Swierkiewicz, Dura Pharmaceuticals, Twombly, Erickson, and Iqbal], we can at least state the following two principles common to all of them. First, to be entitled to the presumption of truth, allegations in a complaint or counterclaim may not simply recite the elements of a cause of action, but must contain sufficient allegations of underlying facts to give fair notice and to enable the opposing party to defend itself effectively. Second, the factual allegations that are taken as true must plausibly suggest an entitlement to relief, such that it is not unfair to require the opposing party to be subjected to the expense of discovery and continued litigation.
Starr,
The district court abused its discretion when it denied AE the opportunity to allege additional facts supporting the claim that Portillo’s, Wampler’s, and Felix’s alleged constitutional violations were carried out pursuant to County policy or custom. AE’s allegation of plausible facts supporting such a policy or custom could have cured the deficiency in the
Monell
claim.
See Telesaurus,
B. State Law Claims
We address AE’s statutory negligence claims by “ascertaining] and applying] the existing California law.” Munson v. Del Taco, Inc., 522 F.3d 997, 1002 (9th Cir.2008) (citation omitted).
California public entities are not subject to common law tort liability; all liability must be pursuant to statute.
See
Cal. Gov’t Code § 815;
see also Guzman v. Cnty. of Monterey,
The district court dismissed both the direct and derivative liability claims against the County with prejudice and without leave to amend. AE waived any challenge to the dismissal of his direct liability claim by failing to “specifically and distinctly” argue the issue in his opening brief.
United States v. Ullah,
The district court erred, however, when it conflated AE’s direct and derivative liability claims and dismissed the latter with prejudice. The court’s legal error constitutes an abuse of discretion.
See Metro-phones,
California public entities, including local governments, are derivatively liable for the negligent acts or omissions of public employees within the scope of their employment.
See
Cal. Gov’t Code § 815.2(a). But if the employee successfully asserts immunity, the public entity is shielded from derivative liability.
See id.
§ 815.2(b);
see also Johnson v. State,
Here, the district court granted AE leave to amend his negligence claims against Portillo, Wampler, and Felix. Because these County social workers remain as defendants in the case, the court erred when it dismissed all claims against the County with prejudice and certified judgment in the County’s favor. As long as AE is permitted to allege that County employees were negligent, he must also be permitted to allege that the County is derivatively liable pursuant to California Government Code § 815.2(a).
On appeal, the County argues that the dismissal was proper because AE’s pleadings make an affirmative showing that Portillo, Wampler, and Felix are entitled to the “discretionary act immunity” set forth in California Government Code § 820.2.
Caldwell v. Montoya,
*639 California Government Code § 820.2 provides that “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 discretion be abused.”
Two principles California courts consider to determine whether discretionary act immunity applies are particularly relevant here.
See Barrier v. Leeds,
Second, government defendants have the burden of establishing that they are entitled to immunity for an actual policy decision made by an employee who “consciously balanced] risks and advantages ...”
Johnson,
The County relies on several California Court of Appeal decisions involving foster care.
See, e.g., Cnty. of Los Angeles v. Superior Court,
The
Terrell R.
court’s analysis sharply departed from the principles outlined in California Supreme Court precedent. The holding that social workers are immune from liability for all nonmandatory acts erroneously conflated direct and derivative liability by interpreting “discretionary” literally rather than legally. This interpretation is inconsistent with the California Supreme Court’s instruction to construe the scope of the discretionary act immunity as narrowly as possible to preserve the separation of powers, and its instruction to determine whether an act is discretionary
*640
by distinguishing between the employee’s operational and policy decisions.
See Barrier,
Applying the holdings of the California Supreme Court, and taking the allegations in the Complaint as true, we conclude that the County was not entitled to dismissal of AE’s derivative liability claims on the basis of discretionary act immunity for the allegedly negligent placement and supervision of AE by Portillo, Wampler, and Felix.
See Elton v. Cnty. of Orange,
The district court abused its discretion by dismissing the derivative liability claims against the County with prejudice and without leave to amend when it granted leave to amend as to the allegations regarding Portillo, Wampler, and Felix. The County’s derivative liability is tied directly to the negligence of, or successful assertion of immunity by, its employees. See Cal. Gov’t Code § 815.2. Nevertheless, the district court concluded that the County’s “alleged liability [was] clear and distinct from claims against and liability of other defendants.” This holding was contrary to California law.
In sum, AE may have viable claims against the County under state law and under federal law. We express no view as to the ultimate disposition of those claims. The success of the state law claim hinges on the liability of the social workers who remain as defendants. And it remains to be seen whether AE can meet the pleading requirements set forth in Iqbal for his § 1983 claim. However, he must be given the opportunity to try to meet those requirements.
CONCLUSION
The district court’s order dismissing the claims against the County without leave to amend is REVERSED and the entry of judgment in favor of the County is VACATED. The case is REMANDED for *641 further proceedings consistent with this opinion.
Notes
. AE’s mother, Maribel Hernandez, was appointed as his Guardian ad Litem for this case.
. This social worker, Heidi Williams, was named as a defendant, but service subsequently was found to be defective.
. The First Amended Complaint also named Family Builders Foster Care, Inc., and the Tulare Youth Service Bureau, Incorporated, as defendants. Those entities were dismissed by the district court and are not before us on appeal.
. No principled basis exists to distinguish harm inflicted by a foster sibling in a foster parent's home.
. Indeed, at several points the First Amended Complaint incorrectly refers to AE as the "Decedent” and alleges "policies, customs, and practices regarding the custody, care and protection of dependent minors ... so inadequate that the failure to correct them would result in ... the death of[ ] dependent minors, such as Plaintiff.” These naked assertions make no sense in the context of this case.
. The district court's error is made even more apparent by the fact that, at the time it denied AE leave to amend, our precedent required no more than the allegation that the government officials acted pursuant to an established policy or custom.
See, e.g., Whitaker,
. It does not suffice that AE, in the "Statement of the Case” and "Statement of Facts” sections of his opening brief, recited — almost verbatim — the bare allegations contained in his First Amended Complaint.
. We note that neither
