*427I. INTRODUCTION
Plaintiff and appellant, Moss Bros. Toy, Inc. (MBT), appeals from the order granting defendant and respondent, Ernesto Ruiz's, anti-SLAPP1 motion, or special motion to strike MBT's entire first amended complaint (FAC) against Ruiz. (§ 425.16, subd. (i).) The FAC alleges MBT is Ruiz's former employer and that Ruiz breached two March 2010 arbitration agreements with MBT by failing to submit Ruiz's employment-related claims against MBT to arbitration, and by instead filing a lawsuit for his employment-related claims *294against MBT's agent, Moss Bros. Auto Group, Inc. (MBAG), in San Bernardino County Superior Court case No. CIVDS2107201. In this appeal, MBT claims the anti-SLAPP motion was erroneously granted because the FAC is not based on protected activity (§ 425.16, subd. (e)), but is instead based on Ruiz's breach of his March 2010 arbitration agreements with MBT. MBT also claims it demonstrated a probability of prevailing on its claims alleged in the FAC.
We affirm the order granting the anti-SLAPP motion. In the published portion of this opinion, we explain that the entire FAC is based on protected activity, namely, Ruiz's act of filing his lawsuit against MBAG for his employment-related claims in case No. CIVDS2107201-even though the FAC is also based on Ruiz's alleged breach of the 2010 arbitration agreements. In the unpublished portion of this opinion, we explain that MBT failed to demonstrate a probability of prevailing on its claims against Ruiz as alleged in the FAC.
*428II. FACTS AND PROCEDURAL BACKGROUND
A. Ruiz's July 2012 Complaint Against MBAG, and MBAG's First Unsuccessful Petition to Compel Arbitration of Ruiz's Employment-related Claims
In July 2012, Ruiz filed a putative class action complaint against MBAG in case No. CIVDS2107201. ( Ruiz v. Moss Bros. Auto Group, Inc. (2014) 232 Cal.App.4th 836, 838, 181 Cal.Rptr.3d 781 ( Ruiz I ).)2 In that action, Ruiz alleged that MBAG was his employer and that MBAG failed to (1) pay Ruiz and other employees overtime and other wages, (2) provide required meal and rest breaks, (3) provide accurate and complete wage statements, (4) reimburse business expenses, and (5) timely pay final wages. The complaint also alleged representative claims and sought civil penalties on behalf of Ruiz, other MBAG employees, and the state pursuant to the Labor Code Private Attorneys General Act of 2004 (PAGA). ( Lab. Code, § 2698 et seq. ; Ruiz I , supra , at p. 838, 181 Cal.Rptr.3d 781.)
In August 2012, MBAG petitioned the trial court to compel arbitration of Ruiz's individual employment-related claims, pursuant to an arbitration agreement that MBAG claimed Ruiz had electronically signed on September 21, 2011 (the 2011 agreement).3 The trial court denied MBAG's petition to compel arbitration, MBAG appealed, and in Ruiz I we affirmed the order denying the petition. We concluded MBAG had failed to present sufficient evidence to meet its burden of showing by a preponderance of the evidence that Ruiz was the person who electronically signed the 2011 agreement, or *295that the 2011 agreement existed, after Ruiz claimed in an opposing declaration that he did not recall electronically signing the 2011 agreement. ( Ruiz I , supra , 232 Cal.App.4th at pp. 838, 840-842, 181 Cal.Rptr.3d 781 ; Civ. Code, § 1633.9.)
We also concluded in Ruiz I that MBAG could not rely on two other arbitration agreements to support its petition-a March 4, 2010, arbitration *429agreement that MBAG claimed Ruiz electronically signed on March 4, 2010, as part of Ruiz's online employment application, and a March 12, 2010, arbitration agreement that MBAG claimed Ruiz signed by hand when he was hired on March 12, 2010. ( Ruiz I , supra , 232 Cal.App.4th at pp. 841, 846, 181 Cal.Rptr.3d 781.) We explained that MBAG's petition sought to compel arbitration based solely on the 2011 agreement, and that MBAG did not mention the 2010 agreements until it filed its reply papers. ( Ibid . ) Thus, the 2010 arbitration agreements were not properly presented to the trial court as a basis to compel arbitration of Ruiz's employment-related claims, and those agreements were not properly before this court in Ruiz I . 4 (Ruiz I , supra , 232 Cal.App.4th at p. 846, 181 Cal.Rptr.3d 781.)
B. MBAG's Second Petition to Compel Arbitration and MBT's Subsequent Motion to Intervene in Case No. CIVDS2107201
In March 2015, shortly after the remittitur issued in Ruiz I , MBAG filed a second petition to compel arbitration of Ruiz's individual employment-related claims. ( Ruiz v. Moss Bros. Toy, Inc. (Mar. 10, 2017, E063953) 2017 WL 944209 [nonpub. opn.] ( Ruiz II ).)5 In its second petition, MBAG claimed for the first time that Ruiz had been employed by MBT , that Ruiz had never been employed by MBAG, and that MBT, not MBAG, had entered into all three arbitration agreements with Ruiz-the two 2010 agreements and the 2011 agreement. ( Id. [at pp. 6-7].)6
Although MBAG's second motion to compel arbitration was based on all three agreements, MBAG argued that the 2011 agreement " 'should control' " because it was the " 'last-in-time' " of the three agreements. ( Ruiz II , supra , E063953 [at p. 7].) MBAG argued it was entitled to compel arbitration of Ruiz's employment-related claims with MBT because MBAG was " 'an intended third-party beneficiary of the [three] arbitration agreements' between Ruiz and MBT ." ( Id . [at p. 9].)7 MBAG
*296wrote that it " 'anticipated' " that MBT would " 'file for joinder in this action' because, as Ruiz's employer, MBT had 'a *430direct interest in both the subject matter and arbitration of [Ruiz's] claims....' " ( Ruiz II , supra , E063953 [at p. 9].)
In April 2015, MBT filed an application to intervene in case No. CIVDS2107201 and to join MBAG's second petition to compel arbitration in that action. ( Ruiz II , supra , E063953 [at p. 9].) Following a May 2015 hearing, the court denied MBAG's second motion to compel arbitration, noting that the motion was " 'nothing more than [an untimely] renewal motion arising from the denial of [MBAG's] earlier petition....' " ( Id . [at p. 10].) The court also denied MBT's application to intervene as untimely, noting the application was " 'nothing more than a thinly-veiled attempt by [MBT] to get yet another bite at the apple as to its enforcement of the 2010 and/or 2011 arbitration agreements that are at the center of this dispute.' " ( Id . [at pp. 10-11].) The court also observed that MBAG and MBT were represented by the same counsel, and that in its first motion to compel arbitration MBAG adduced that MBT was Ruiz's " 'actual employer,' " but MBT did not seek to intervene " 'at that time.' " ( Id . [at p. 11].)
In Ruiz II , we affirmed the order denying MBT's application to intervene in case No. CIVDS2107201. ( Ruiz II , supra , E063953 [at pp. 12-18].) We explained that MBT had unreasonably delayed in applying to intervene, there was no excuse for the delay, and MBT did not explain why it did not seek to intervene at the outset of Ruiz's suit against MBAG in case No. CIVDS2107201. ( Id. [at pp. 14-18].) MBT did not seek to intervene in the action until after MBAG had appealed the denial of its first petition to compel arbitration, and until after we affirmed the denial of MBAG's first petition to compel arbitration in Ruiz I . ( Ruiz II , supra , E063953 [at p. 18].)
C. MBT's Current Lawsuit Against Ruiz
In September 2015, shortly after the trial court denied MBT's application to intervene in case No. CIVDS2107201, MBT filed a complaint against Ruiz in Riverside County Superior Court, case No. RIC1511040, for breach of written contract for arbitration of disputes and breach of the covenant of good faith and fair dealing. The complaint alleged Ruiz breached the March 4 and March 12, 2010, arbitration agreements by "fail[ing] to submit his employment-related disputes to binding arbitration" and by instead "fil[ing] a [c]omplaint" against MBAG for his employment-related claims in San Bernardino County Superior Court, case No. CIVDS2107201. MBT also filed a "notice of related cases," advising the *431Riverside County Superior Court that its newly filed action in Riverside County Superior Court case No. RIC1511040 was related to San Bernardino County Superior Court case No. CIVDS2107201. Case No. RIC1511040 was transferred to San Bernardino County and was assigned, as case No. CIVDS1603069, to Judge Pacheco, the judge presiding over case No. CIVDS2107201 and who had issued the orders appealed in Ruiz I and Ruiz II . MBT moved to consolidate the two cases, but Judge Pacheco denied the motion "as an improper attempt to circumvent the Court's prior ruling on [MBT's] motion to intervene...." MBT also petitioned to compel arbitration of the breach of contract and employment-related claims in both cases-this was the third motion to compel arbitration of Ruiz's individual employment-related claims-but this motion was also denied.
The court sustained Ruiz's demurrer to MBT's complaint with leave to amend, and MBT later filed the FAC. The FAC alleges *297three causes of action against Ruiz: breach of written contract for arbitration of disputes, breach of the covenant of good faith and fair dealing, and specific performance of MBT's arbitration contracts with Ruiz. Each cause of action is based on Ruiz's act of refusal to submit his employment-related claims to arbitration and his act of filing of his putative class action complaint against MBAG in case No. CIVDS2107201.
The FAC specifically alleges Ruiz was employed by MBT and Ruiz breached the 2010 arbitration agreements with MBT by "fail[ing] to submit his employment-related disputes" to arbitration and, "by filing a Complaint for employment-related claims [against MBAG] ... in Case No. CIVDS2107201."8 (Italics added.) The FAC alleges MBAG is "a third-party beneficiary" of the 2010 arbitration agreements because MBAG is MBT's agent, and an affiliate of MBT's employee benefit and health plans, and by signing the 2010 arbitration agreements, Ruiz agreed to arbitrate all employment-related claims against MBT and its agents and such affiliates. Regarding damages, the FAC alleges that, by signing the 2010 arbitration agreements, Ruiz "waived [his] right to represent a class" or file a putative class action lawsuit on behalf of other automotive technicians, and, as a result, MBT has incurred and will incur attorney fees, legal costs, lost employee time, and other damages in responding to "class discovery," and an anticipated "[m]otion for [c]lass [c]ertification." The FAC alleges MBT may be liable for any damages its agent, MBAG, is found liable for in case No. CIVDS2107201. Finally, the FAC seeks specific performance of Ruiz's 2010 arbitration agreements with MBT.
*432D. The Trial Court's Ruling on Ruiz's Anti-SLAPP Motion
Ruiz moved to strike the entire FAC as a SLAPP ( § 425.16 ) along with a general demurrer to the entire FAC (§ 430.10, subds. (e), (f)). The court granted the anti-SLAPP motion and deemed the demurrer moot. In granting the anti-SLAPP motion, the court ruled Ruiz had shown that "the alleged acts were in furtherance of his right of petition" and MBT had failed to demonstrate a probability of prevailing on its claims as alleged in the FAC. MBT timely filed this appeal. ( §§ 425.16, subd. (i), 904.1.)
III. DISCUSSION
A. Applicable Legal Principles and Standard of Review
"The anti-SLAPP statute ' "is designed to protect citizens in the exercise of their First Amendment constitutional rights of free speech and petition. It is California's response to the problems created by meritless lawsuits brought to harass those who have exercised these rights.' " [Citation.]" ( Century 21 Chamberlain & Associates v. Haberman (2009) 173 Cal.App.4th 1, 6, 92 Cal.Rptr.3d 249. ( Haberman ).) The anti-SLAPP statute provides: "A cause of action against a person arising from any act of that person in furtherance of the person's right of petition or free speech ... shall be subject to a special motion to strike, unless the court determines ... there is a probability that the plaintiff will prevail on the claim ." ( § 425.16, subd. (b)(1), italics added.)
"Resolution of an anti-SLAPP motion involves two steps." ( Baral v. Schnitt (2016) 1 Cal.5th 376, 384, 205 Cal.Rptr.3d 475, 376 P.3d 604 ( Baral ).) The *298court first determines whether the defendant has met its burden of making a threshold showing that the challenged claim "arises from" activity protected by section 425.16. ( Ibid. ) The defendant meets this burden by showing that the "act" underlying the claim-that is, the act constituting the factual basis of the claim-fits one of the four categories of protected activities described in section 425.16, subdivision (e). (See Navellier v. Sletten (2002) 29 Cal.4th 82, 88, 124 Cal.Rptr.2d 530, 52 P.3d 703 ( Navellier ).)
If the court determines the defendant has met its threshold burden, it then determines whether the plaintiff has demonstrated a probability of prevailing on the merits of the challenged claim. ( Baral , supra , 1 Cal.5th at pp. 384-385, 205 Cal.Rptr.3d 475, 376 P.3d 604.) To meet its burden, the plaintiff must state and substantiate a legally sufficient claim; it must show that the challenged claim is both legally sufficient and supported by a prima facie evidentiary showing of facts to sustain a favorable judgment if the evidence submitted by the plaintiff is credited. (See Navellier , supra , 29 Cal.4th at pp. 88-89, 124 Cal.Rptr.2d 530, 52 P.3d 703.)
*433In the anti-SLAPP context, a claim is not to be confused with a cause of action. (See § 425.16, subd. (b)(1) ; Baral , supra , 1 Cal.5th at p. 393, 205 Cal.Rptr.3d 475, 376 P.3d 604.) A claim is an act underlying a cause of action, but it is not necessarily the sole act underlying the cause of action. (See Baral , supra , at pp. 384-393, 205 Cal.Rptr.3d 475, 376 P.3d 604.) This distinction is important when a cause of action is based on protected and unprotected activity. Section 425.16 is designed to eliminate only those parts of a cause of action which are based on the defendant's protected activity and which the plaintiff cannot substantiate. ( Baral , supra , at p. 393, 205 Cal.Rptr.3d 475, 376 P.3d 604.)
We review an order granting or denying an anti-SLAPP motion de novo. ( Flatley v. Mauro (2006) 39 Cal.4th 299, 325, 46 Cal.Rptr.3d 606, 139 P.3d 2.) That is, we exercise our independent judgment in determining whether the challenged claim arises from protected activity, and if so whether the plaintiff has demonstrated a probability of prevailing on the claim. ( Park v. Board of Trustees of California State University (2017) 2 Cal.5th 1057, 1067, 217 Cal.Rptr.3d 130, 393 P.3d 905 ( Park ).) In determining whether a challenged claim arises from protected activity, we "consider the pleadings, and supporting and opposing affidavits stating the facts upon which the liability or defense is based." ( § 425.16, subd. (b)(2) ; Navellier , supra , 29 Cal.4th at p. 89, 124 Cal.Rptr.2d 530, 52 P.3d 703.)
B. The Entire FAC Is Based on Ruiz's Protected Right of Petition
MBT claims none of the causes of action or claims alleged in the FAC arise from Ruiz's protected right of petition. We disagree. As we explain, the entire FAC is based on Ruiz's protected right of petition. ( § 425.16, subd. (e)(1), (2).)
As noted, section 425.16 provides: "A cause of action against a person arising from any act of that person in furtherance of the person's right of petition or free speech under the United States Constitution or the California Constitution in connection with a public issue shall be subject to a special motion to strike...." ( § 425.16, subd. (b)(1), italics added.) For these purposes, an " 'act in furtherance of a person's right of petition or free speech' " includes the four categories of activities described in section 425.16, subdivision (e). The relevant categories here are: "(1) any written or oral statement or writing made before a legislative, executive, *299or judicial proceeding, ..., (2) any written or oral statement or writing made in connection with an issue under consideration or review by a legislative, executive, or judicial body ...." ( § 425.16, subd. (e)(1), (2).)
"A claim arises from protected activity when that activity underlies or forms the basis for the claim. [Citations.] Critically, 'the defendant's act underlying the plaintiff's cause of action must itself have been an act in *434furtherance of the right of petition or free speech.' [Citations.] '[T]he mere fact that an action was filed after protected activity took place does not mean the action arose from that activity for the purposes of the anti-SLAPP statute.' [Citations]. Instead, the focus is on determining what 'the defendant's activity [is] that gives rise to his or her asserted liability-and whether that activity constitutes protected speech or petitioning.' [Citation.] 'The only means specified in section 425.16 by which a moving defendant can satisfy the ["arising from"] requirement is to demonstrate that the defendant's conduct by which plaintiff claims to have been injured falls within one of the four categories described in subdivision (e)....' [Citation.] In short, in ruling on an anti-SLAPP motion, courts should consider the elements of the challenged claim and what actions by the defendant supply those elements and consequently form the basis for liability." ( Park , supra , 2 Cal.5th at pp. 1062-1063, 217 Cal.Rptr.3d 130, 393 P.3d 905.)
Here, Ruiz's anti-SLAPP motion is directed to the entire FAC. Although the FAC alleges three causes of action, it effectively pleads a single "claim" against Ruiz for his breach of the 2010 arbitration agreements with MBT based on his refusal to submit his individual employment-related claims to arbitration and his act of instead filing a putative class action complaint for those claims and others against MBT's agent, MBAG, in case No. CIVDS2107201. ( Navellier , supra , 29 Cal.4th at p. 92, 124 Cal.Rptr.2d 530, 52 P.3d 703 ["The anti-SLAPP statute's definitional focus is not the form of the plaintiff's cause of action but, rather, the defendant's activity that gives rise to his or her asserted liability-and whether that activity constitutes protected speech or petitioning."].)
The FAC alleges Ruiz "breached the arbitration contracts by filing a complaint for employment-related claims" against MBAG, and if MBAG is found liable in case No. CIVDS2107201, then MBT may be liable for the actions of its agent, MBAG, even though MBT is not a named defendant in the case. The FAC seeks money damages for MBT's liability, if any, in case No. CIVDS2107201, and for "legal costs, attorney fees, and time spent" by MBT's employees and officers in responding to class discovery in case No. CIVDS2107201, which the FAC alleges MBT would not have incurred if Ruiz had submitted his individual employment-related claims to arbitration as the 2010 agreements required. The FAC also seeks a judgment compelling Ruiz's specific performance of the 2010 arbitration agreements. Thus, the FAC is based entirely on Ruiz's protected act of filing the complaint against MBAG, an act Ruiz took "in furtherance of [his] right of petition...." ( § 425.16, subd. (b)(1) ; Navellier , supra , 29 Cal.4th at p. 90, 124 Cal.Rptr.2d 530, 52 P.3d 703 [the constitutional right of petition encompasses " ' " 'the basic act of filing litigation.' " ' "].)
*435Navellier is instructive. There, the defendant, Sletten, entered into an agreement and a release of claims (the Release), with the plaintiffs, after the plaintiffs sued Sletten in federal district court. ( *300Navellier , supra , 29 Cal.4th at pp. 85-86, 124 Cal.Rptr.2d 530, 52 P.3d 703.) The plaintiffs later filed an amended complaint in the federal court action, and Sletten filed counterclaims for breach of the Release and related claims. ( Id . at p. 86, 124 Cal.Rptr.2d 530, 52 P.3d 703.) After the plaintiffs and Sletten lost on their respective claims in the federal court action, the plaintiffs sued Sletten in state court, "alleging that Sletten had committed fraud in misrepresenting his intention to be bound by the Release, so as to induce plaintiffs to incur various litigation costs in the federal action that they would not have incurred had they known Sletten's true intentions. Plaintiffs also alleged Sletten had committed breach of contract by filing counterclaims in the federal action." ( Id . at p. 87, 124 Cal.Rptr.2d 530, 52 P.3d 703.) Sletten filed a special motion to strike the plaintiffs' entire complaint as a SLAPP. ( Ibid . )
The Navellier court held that the plaintiffs' complaint against Sletten for breach of the Release was based on Sletten's protected act of filing his counterclaims in the federal court action. ( Navellier, supra, 29 Cal.4th at p. 90, 124 Cal.Rptr.2d 530, 52 P.3d 703.) The court reasoned: "Sletten is being sued because of the affirmative counterclaims he filed in federal court. In fact, but for the federal lawsuit and Sletten's alleged actions taken in connection with that litigation, plaintiffs' present claims would have no basis . This action therefore falls squarely within the ambit of the anti-SLAPP statute's 'arising from' prong." ( Ibid. , italics added, fn. omitted.)
Similarly here, MBT is suing Ruiz because of the putative class action complaint Ruiz filed against MBAG. But for Ruiz's filing of the complaint against MBAG, MBT's FAC against Ruiz for breach of the 2010 arbitration agreements would have no factual basis , and MBT would not have incurred any of the damages the FAC alleged MBT has and will incur as a result of Ruiz's breach of the 2010 arbitration agreements and his failure to submit his individual employment-related claims to arbitration. In the language of section 425.16, Ruiz's act of filing the complaint against MBAG involved Ruiz's "statement[s] or writing[s] made before a ... judicial proceeding" ( § 425.16, subd. (e)(1) ), and "statement[s] or writing[s] made in connection with an issue under consideration or review by a ... judicial body" (id ., subd. (e)(2)). That is, Ruiz's act of filing the complaint against MBGA involved Ruiz's protected " ' " 'basic act of filing litigation.' " ' " ( Navellier , supra , 29 Cal.4th at p. 90, 124 Cal.Rptr.2d 530, 52 P.3d 703.)
MBT argues the FAC is not based on Ruiz's protected right of petition, but is instead based on Ruiz's breach of the 2010 arbitration agreements and *436MBT's contractual right to enforce Ruiz's performance of those agreements. To be sure, the FAC is based on Ruiz's breach of the 2010 arbitration agreements and on MBT's alleged right to enforce Ruiz's performance of those agreements. But this does not mean the FAC cannot also be based, and is not also based, on Ruiz's protected right of petition or act of filing the complaint against MBAG.
The Navellier court rejected a similar claim. The plaintiffs in Navellier argued their complaint was not covered by section 425.16, but was, instead, " 'a garden variety breach of contract and fraud claim.' " ( Navellier , supra , 29 Cal.4th at p. 90, 124 Cal.Rptr.2d 530, 52 P.3d 703.) As the Navellier court explained, this claim is based on the "false dichotomy between actions that target 'the formation or performance of contractual obligations' and those that target 'the exercise of the right of free speech.' [Citation.] A given action, or cause of action, may indeed target both.... [C]onduct alleged to constitute breach of *301contract may also come within constitutionally protected speech or petitioning." ( Id . at p. 92, 124 Cal.Rptr.2d 530, 52 P.3d 703.)9
MBT's reliance on Haberman , supra , 173 Cal.App.4th 1, 92 Cal.Rptr.3d 249 is misplaced. There, the plaintiffs sued Haberman for account stated, alleging she failed to pay interest on a loan, and for declaratory relief that there was no agreement to submit the account stated claim to private arbitration. ( Id . at p. 6, 92 Cal.Rptr.3d 249.) The Haberman court held neither claim arose from Haberman's protected activity. ( Id . at p. 7, 92 Cal.Rptr.3d 249.) Instead, the account stated claim arose from Haberman's alleged act of failing to pay interest on the loan, and the declaratory relief claim arose from Haberman's alleged act of demanding that the plaintiffs arbitrate a negligence claim against them. ( Id . at pp. 7-8, 92 Cal.Rptr.3d 249.) Regarding the declaratory relief claim, the court explained that a demand to commence private arbitration does not fall into any of the four categories of protected activity described in section 425.16, subdivision (e). ( Haberman , supra , at pp. 7-9, 92 Cal.Rptr.3d 249.) The court explained, "[a]rbitration is not a judicial proceeding-it is an alternative thereto[,]" and arbitration is also not an " 'official proceeding authorized by law.' " ( Id . at p. 8, 92 Cal.Rptr.3d 249 ; § 425.16, subd. (e)(1), (2).) A demand to commence private arbitration also does not fall into the final two categories of protected activity described in section 425.16, subdivision (e), which *437protect "statements 'made in ... a public forum in connection with an issue of public interest' ( § 425.16, subd. (e)(3) ) and 'conduct ... in connection with a public issue or an issue of public interest.' ( § 425.16, subd. (e)(4).)" ( Haberman , supra , at p. 9, 92 Cal.Rptr.3d 249.)
Haberman does not support MBT's argument that the FAC is based on Ruiz's breach of the 2010 arbitration agreements rather than on Ruiz's protected right of petition in filing the putative class action complaint against MBAG. Unlike the FAC, the complaint in Haberman was not based on Haberman's protected act of filing a lawsuit. Instead, the complaint sought declaratory relief that no arbitration agreement existed, and was therefore based on Haberman's demand for private arbitration , which is not a protected activity. ( Haberman , supra , 173 Cal.App.4th at pp. 7-9, 92 Cal.Rptr.3d 249.) The FAC is not based on the unprotected act of demanding private arbitration. It is instead based on Ruiz's protected act of filing the complaint against MBAG.
MBT also relies on City of Alhambra v. D'Ausilio (2011) 193 Cal.App.4th 1301, 123 Cal.Rptr.3d 142 ( City of Alhambra ) for the proposition that the FAC is based on Ruiz's unprotected act of refusing to arbitrate his individual employment-related claims with MBT-that is, Ruiz's breach of the 2010 arbitration agreements. City of Alhambra is also distinguishable. In that case the defendant, D'Ausilio, a former employee of the City of Alhambra and president of the Alhambra Firefighters' Association (AFA), sued the city for civil rights violations, and the parties entered *302into a settlement agreement. ( Id. at pp. 1303-1304, 123 Cal.Rptr.3d 142.) As part of the settlement agreement, D'Ausilio agreed not to " 'represent, participate, or advocate for, any Alhambra employee(s)' including AFA members" for a period of approximately five years between 2007 and 2012. In October 2008, D'Ausilio allegedly breached the settlement agreement by (1) participating in an AFA meeting and advocating that AFA members join a demonstration against the city, and (2) participating in a protest by city employees against the city. ( Id. at p. 1304, 123 Cal.Rptr.3d 142.) The city sued D'Ausilio for breach of contract, money had and received, and declaratory relief that the settlement agreement was valid and D'Ausilio had breached the agreement. ( Id . at pp. 1304-1305, 123 Cal.Rptr.3d 142.) D'Ausilio countersued, "seeking a nearly identical judicial declaration," and filed a special motion to strike the city's cause of action for declaratory relief. ( Id . at p. 1305, 123 Cal.Rptr.3d 142.)
The City of Alhambra court held that the declaratory relief claim was not based on D'Ausilio's protected activity of participating in the demonstrations against the city, but was instead based on the parties' "actual, present controversy ... regarding the scope and enforceability" of the settlement agreement. ( City of Alhambra , supra , 193 Cal.App.4th at p. 1307, 123 Cal.Rptr.3d 142.) The court reasoned: "The City did not sue [D'Ausilio] because he engaged in protected speech; the City sued him because it believed he breached a contract which *438prevented him from engaging in certain speech-related conduct and a dispute exists as to the scope and validity of that contract." ( Id . at p. 1308, 123 Cal.Rptr.3d 142.) Here, in contrast, MBT sued Ruiz because he filed the putative class action complaint against MBAG rather than submit his individual employment related claims to arbitration.
In a subsequent anti-SLAPP case, Mundy v. Lenc (2012) 203 Cal.App.4th 1401, 138 Cal.Rptr.3d 464 ( Mundy ), Division Two of the Second Appellate District-the same court that decided City of Alhambra -distinguished City of Alhambra as "[arising] over the enforceability and scope of a settlement agreement and not from the plaintiff's exercise of the right of petition." ( Mundy , supra , at p. 1408, 138 Cal.Rptr.3d 464.) The plaintiff, Mundy, a disabled person, sued Lenc, a bar owner, alleging Lenc failed to comply with the Americans with Disabilities Act (ADA; 42 U.S.C. § 12101 et seq. ). ( Id . at pp. 1404-1405, 138 Cal.Rptr.3d 464.) The parties entered into a settlement agreement, which included a general release of claims and a Civil Code section 1542 waiver, whereby Mundy agreed to waive unknown and unanticipated ADA claims against Lenc. ( Mundy , supra , at p. 1405, 138 Cal.Rptr.3d 464.)
Despite the settlement agreement, Mundy sued Lenc a second time for another ADA violation, and Lenc cross-complained against Mundy for breach of the settlement agreement. ( Mundy , supra , 203 Cal.App.4th at p. 1405, 138 Cal.Rptr.3d 464.) Mundy moved to strike the cross-complaint as a SLAPP. ( Ibid . ) The Mundy court held the cross-complaint was based on Mundy's protected activity in filing the second ADA action against Lenc, and distinguished its decision in City of Alhambra as involving a "dispute ... over the enforceability and scope of a settlement agreement and not [arising] from the plaintiff's exercise of the right of petition." ( Mundy , supra , at pp. 1408-1409, 138 Cal.Rptr.3d 464.)
Like Mundy , other courts have recognized the critical distinction, in the anti-SLAPP context, between claims based on the protected act of filing a lawsuit and claims based solely or distinctly on the *303alleged breach of an agreement, and similar claims for declaratory relief. For example, in City of Cotati v. Cashman (2002) 29 Cal.4th 69, 124 Cal.Rptr.2d 519, 52 P.3d 695, the court held the city's state court action against mobilehome park owners for a judgment declaring the city's rent stabilization ordinance constitutional was not based on protected activity-because the city's action was not based on the owners' protected act of filing a federal court action seeking to declare the same ordinance unconstitutional. Instead, the city's action-indeed both parties' actions-were based on the parties' dispute concerning the constitutionality of the ordinance. ( Id . at p. 80, 124 Cal.Rptr.2d 519, 52 P.3d 695.)
Vivian v. Labrucherie (2013) 214 Cal.App.4th 267, 153 Cal.Rptr.3d 707 is similarly instructive. There, the plaintiff's breach of contract claims were *439based on the defendant's protected activity of making statements to internal affairs investigators and in family court papers-even though, by his challenged claims, the plaintiff was seeking damages for the defendant's breach of a settlement agreement "not to disparage" the plaintiff based on the defendant's protected statements. ( Id . at pp. 270-271, 274, 153 Cal.Rptr.3d 707.) Because the plaintiff was seeking to impose liability on the defendant for her acts of making protected statements, the plaintiff's action was based on protected activity. ( Id . at p. 274, 153 Cal.Rptr.3d 707.)
More recently, in Park , supra , 2 Cal.5th 1057, 217 Cal.Rptr.3d 130, 393 P.3d 905, the high court explained that, for a claim to be based on protected activity, the protected activity "must supply the elements of the challenged claim." ( Id . at p. 1064, 217 Cal.Rptr.3d 130, 393 P.3d 905.) The court approved the challenged claims in Navellier as meeting this standard: "The defendant's [protected] filing of counterclaims constituted the alleged breach of contract," and likewise, "the defendant's misrepresentation of his intent not to file counterclaims [a protected statement made in connection with a pending judicial matter ( § 425.16, subd. (e)(1), (2) ) ] supplied an essential element of the fraud claim." ( Park , supra , at p. 1064, 217 Cal.Rptr.3d 130, 393 P.3d 905.) The court also explained that a claim is not based on protected activity if it was filed merely because of protected activity, and noted the distinction between activities that form the basis of a claim and activities that "merely lead to the liability-creating activity or provide evidentiary support for the claim." ( Ibid . )
Each of these standards was met here. As discussed, the entire FAC is based on Ruiz's protected act of filing the complaint against MBAG, because Ruiz's act of filing that complaint against MBAG constitutes the entire basis of the FAC's singular breach of contract claim. Ruiz's act of filing the complaint against MBAG does not merely provide evidentiary support for the MBT's breach of contract claim, and the FAC was not filed merely because Ruiz filed the complaint against MBAG. ( Park , supra , 2 Cal.5th at p. 1064, 217 Cal.Rptr.3d 130, 393 P.3d 905.) To the contrary, Ruiz's protected act of filing the complaint against MBAG constitutes the " 'conduct by which plaintiff [MBT] claims to have been injured .' " ( Id. at p. 1063, 217 Cal.Rptr.3d 130, 393 P.3d 905 ; Equilon Enterprises v. Consumer Cause, Inc. (2002) 29 Cal.4th 53, 66, 124 Cal.Rptr.2d 507, 52 P.3d 685.)
C.-D.
