ACCURSIO v. TREE HOUSE LABS, LLC Opinion of the Court

JUSTICE KING authored the Opinion of the Court, in which CHIEF JUSTICE TIMMER, VICE CHIEF JUSTICE LOPEZ, and JUSTICES BOLICK and BEENE joined. JUSTICE MONTGOMERY, joined by JUSTICE CRUZ, dissented.

JUSTICE KING, Opinion of the Court:

¶1 The rules of professional conduct governing lawyers are in Rule 42 of the Rules of the Supreme Court of Arizona.1 See Ariz. R. Sup. Ct. 42 (setting forth the Ethical Rules). An individual or entity may file a charge with the State Bar of Arizona (“State Bar”) alleging unprofessional conduct by a lawyer or the unauthorized practice of law. See Ariz. R. Sup. Ct. 53, 55(a), 77(a), 78(a). “Communications to the . . . state bar . . . relating to lawyer misconduct, lack of professionalism or disability, and testimony given in the proceedings shall be absolutely privileged conduct, and no civil action predicated thereon may be instituted against any complainant or witness.” Ariz. R. Sup. Ct. 48(l); see also Ariz. R. Sup. Ct. 80(a)(6) (“Communications to the . . . state bar . . . relating to alleged unauthorized practice of law, and testimony given in the proceedings shall be absolutely privileged conduct, and no civil action predicated thereon may be instituted against any complainant or witness.”). Rules 48(l) and 80(a)(6) also provide that certain enumerated people “shall be immune from suit for” their conduct, but that list of people does not include complainants who file charges.

¶2 In this case, we consider whether Plaintiff John Accursio may maintain a wrongful institution of civil proceedings (“WICP”) claim against Defendant Clark Wu on the basis that Wu filed a charge against Accursio with the State Bar. In doing so, we must determine whether the filing of a charge with the State Bar is a “civil proceeding” for purposes of a WICP claim. We conclude the filing of such a charge may serve as the predicate

the “Rules.”

ACCURSIO v. TREE HOUSE LABS, LLC Opinion of the Court

“civil proceeding” for a WICP claim. Also, Rules 48(l) and 80(a)(6) do not immunize a complainant from a WICP claim for the act of filing a charge. These Rules merely provide that statements made to the State Bar or given in testimony are privileged, and a civil action may not rely upon such privileged statements. A plaintiff in a WICP action, however, may rely upon relevant, admissible evidence that is not privileged, such as the complainant’s non-privileged communications, the timing of filing, and other background facts.

¶3 We also consider when the “civil proceeding” commences, as such timing is relevant to a WICP claim. We conclude the timing depends on the nature of the charge. When a charge alleges a lawyer admitted to practice in Arizona has violated the Ethical Rules, the “civil proceeding” commences when the lawyer is provided written notice of a screening investigation and required to provide a written response to the allegations. See Ariz. R. Sup. Ct. 55(b)(1). When a charge alleges a person has engaged in the unauthorized practice of law, such “proceeding commences upon receipt by the state bar of a charge against a respondent.” Ariz. R. Sup. Ct. 78(a).

¶4 Accursio’s complaint sufficiently alleges that the charge Wu filed with the State Bar commenced a “civil proceeding,” and Accursio alleges non-privileged facts in support of his claims. Therefore, we reverse the dismissal of Accursio’s WICP and related aiding and abetting claims under Arizona Rule of Civil Procedure 12(b)(6) for failure to state a claim upon which relief can be granted. On remand, the trial court will determine whether Accursio can prove a WICP claim without considering the content of privileged communications to the State Bar, an issue that is not before us.

BACKGROUND

¶5 Accursio appeals the trial court’s dismissal of his WICP and aiding and abetting claims for failure to state a claim upon which relief can be granted. See Ariz. R. Civ. P. 12(b)(6). For purposes of evaluating this motion to dismiss, we “must . . . assume the truth of the well-pled factual allegations and indulge all reasonable inferences therefrom.” Cullen v. Auto-Owners Ins. Co., 218 Ariz. 417, 419 ¶ 7 (2008). Therefore, the facts here are taken from Accursio’s complaint.

ACCURSIO v. TREE HOUSE LABS, LLC Opinion of the Court

¶6 This case began with a dispute over ownership interests in Tree House Labs, LLC and access to business records. In 2021, Tree House Labs and others filed a lawsuit in Maricopa County Superior Court, Case No. CV2021-019322 (the “Underlying Action”). Wu and his law firm, BB Group, LLC, represented the plaintiffs in the Underlying Action. Accursio, a lawyer admitted to practice in New York and Washington, D.C., represented the defendants in the Underlying Action. Two lawyers admitted to practice in Arizona served as co-counsel with Accursio (“Arizona co-counsel”), also representing the defendants in the Underlying Action. At some point during those proceedings, Accursio told Wu that BB Group’s representation of the plaintiffs appeared to violate conflict of interest provisions in the Ethical Rules. In 2022, the plaintiffs voluntarily dismissed the Underlying Action.

¶7 Since 2021, Accursio and Arizona co-counsel have made multiple requests for records from Wu’s clients. More recently, Wu indicated that Accursio’s clients needed to sign a non-disclosure agreement before Wu’s clients would provide the requested records. Wu sent a draft non-disclosure agreement to Accursio and Arizona co-counsel. Accursio reviewed the agreement and sent a second draft version to Wu and Arizona co-counsel. Shortly after, Wu accused Accursio of engaging in the unauthorized practice of law in Arizona. Accursio replied that his conduct was permissible under Ethical Rule 5.5, as he was associating with Arizona co-counsel. See Ariz. R. Sup. Ct. 42, Ethical Rule 5.5(c)(1) (allowing a lawyer admitted in another United States jurisdiction to provide temporary legal services that involve Arizona law under certain circumstances, including when “undertaken in association with a lawyer who is admitted to practice in Arizona and who actively participates in the matter”).

¶8 Accursio contacted the State Bar and was purportedly informed that his representation qualified for the exception in Ethical Rule 5.5. In addition, Accursio discussed with the State Bar Wu’s potential conflict of interest, and filed a bar charge against Wu, Charge No. 22-1747.

¶9 Accursio then informed Wu of the charge that he filed against him. Immediately thereafter, Wu filed a charge with the State Bar against Accursio, Charge No. 22-1748, alleging that Accursio had engaged in the unauthorized practice of law in Arizona. As a result of this charge, a State

Bar staff member contacted Accursio and requested information from him. Accursio drafted and delivered a response letter to the State Bar.

¶10 Later, Accursio received a letter from Senior Bar Counsel explaining that “a screening investigation is being undertaken pursuant to Rule 55(b), Ariz. R. Sup. Ct.” The letter also stated:
