Opinion

IN THE COURT OF APPEALS OF THE STATE OF WASHINGTON AUSTIN I. STONE, an individual person, No. 88714-9-I Appellant, DIVISION ONE v. PUBLISHED OPINION

KING COUNTY, a political subdivision of the State of Washington; and GEORGE EPPLER, a KING COUNTY EMPLOYEE who is an individual person,

Respondents.

FELDMAN, J. — Austin Stone appeals the trial court’s order dismissing his legal malpractice and breach of fiduciary duty claims against his former criminal defense attorney, George Eppler, on causation grounds under CR 12(b)(6). In the underlying proceeding in which Eppler represented Stone, the court (referred to herein as the sentencing court) erroneously imposed a sentence of supervised probation. Stone alleges that Eppler had and breached a duty to ensure that the sentencing court imposed a sentence of unsupervised probation in accordance with the parties’ joint recommendation and the sentencing court’s stated intent. The trial court below concluded that the sentencing court’s error is a superseding cause and therefore severs the causal connection between Eppler’s breach and

Stone’s injury. 1 Because the trial court erred in applying the controlling legal principles regarding intervening acts and superseding cause to the alleged and properly hypothesized facts, we reverse the court’s dismissal of these claims and remand the matter for further proceedings consistent with this opinion.

I

Stone assigns error to the trial court’s dismissal of his claims under CR 12(b)(6). Accordingly, the following statement of facts accepts as true the allegations contained in his complaint. See Tang Real Estate Invs., Corp. v. Escrow Servs. of Wash., 30 Wn. App. 2d 602, 604, 546 P.3d 453 (2024).

Stone alleges that, in early 2022, he “was being prosecuted by the State of Washington” and Eppler was his “attorney-in-fact to defend against the criminal allegations.” During the representation, Eppler “reached a plea agreement with the State of Washington on behalf of” Stone, which “involved unsupervised probation.” Stone further alleges that the matter proceeded to a judgment and sentence hearing on May 27, 2022, at which “the judge, the prosecutor, MR. EPPLER, and MR. STONE all had the same understanding: MR. STONE was to be placed on unsupervised probation.” Further, “[t]he oral ruling of the judge . . . confirmed the unsupervised probation of MR. STONE.”

1 Because the sole issue on appeal is causation, we assume without deciding that Stone has

established the remaining elements of his claims, including breach and injury. Stone also asserted a negligent training claim against Eppler’s employer, King County. The trial court concluded that this claim is subsumed by Stone’s remaining claims under LaPlant v. Snohomish County, 162 Wn. App. 476, 271 P.3d 254 (2011), because Stone did not dispute that Eppler was acting in the course and scope of his employment at the time of the tortious conduct. Stone expressly concedes this point on appeal and does not assign error to this portion of the trial court’s ruling, so we need not— and do not—discuss this claim further.

Notwithstanding this shared understanding, Stone’s complaint alleges that the written judgment and sentence, which the parties provided to the sentencing court at the hearing and the court accepted, “was erroneous and did not match the oral ruling that was issued.” Instead of unsupervised probation, the judgment and sentence imposed a 12-month term of probation supervised by the Washington State Department of Corrections (DOC). Following this hearing, Stone did not contact DOC before leaving Washington because he believed the judgment and sentence had specified unsupervised probation. When he later returned to Washington, he was arrested and “subjected to solitary confinement” and “electronic home monitoring in the State of Washington” because he had failed to report to DOC for his supervised probation. Stone succeeded in obtaining a corrected judgment and sentence.

Stone thereafter filed a complaint and amended complaint against Eppler asserting claims for legal malpractice and breach of fiduciary duty. Both claims allege that Eppler had and breached a duty to Stone to “use due care” when reviewing the “Judgment and Sentence paperwork” and “to ensure the Judgment and Sentence paperwork was an accurate reflection of the Judicial Officer’s oral rulings.” Eppler filed a motion to dismiss the claims under CR 12(b)(6). He argued that “[b]ecause the judge was presented with all material information . . . the judge’s order . . . was an intervening, superseding cause for any alleged error by Eppler.” The trial court granted Eppler’s motion and dismissed Stone’s claims with prejudice. This timely appeal followed.

II

Stone argues the trial court erred in dismissing his legal malpractice and breach of fiduciary duty claims on causation grounds under CR 12(b)(6). We agree.

A

This court reviews a trial court’s order granting a motion to dismiss under CR 12(b)(6) de novo. Wahkiakum Sch. Dist. No. 200 v. State, 2 Wn.3d 63, 77, 534 P.3d 808 (2023). Dismissal under CR 12(b)(6) is appropriate if “‘it appears beyond doubt that the plaintiff can prove no set of facts, consistent with the complaint, which would entitle the plaintiff to relief.’” Bowman v. John Doe Two, 104 Wn.2d 181, 183, 704 P.2d 140 (1985) (quoting Orwick v. Seattle, 103 Wn.2d 249, 254, 692 P.2d 793 (1984)). “We presume the facts in the complaint are true and reject the motion to dismiss if ‘[a]ny hypothetical situation conceivably raised by the complaint . . . is legally sufficient to support the plaintiff’s claim.’” Tavaglione v. Dehkhoda & Qadri, P.C., 34 Wn. App. 2d 515, 520, 568 P.3d 1158 (2025) (quoting Jackson v. Quality Loan Serv. Corp. of Wash., 186 Wn. App. 838, 843, 347 P.3d 487 (2015)). “Documents whose contents are alleged in a complaint but which are not physically attached to the pleading may also be considered in ruling on a CR 12(b)(6) motion to dismiss.” Rodriguez v. Loudeye Corp., 144 Wn. App. 709, 726, 189 P.3d 168 (2008).

“In a tort action against attorneys that alleges legal malpractice and breach of a fiduciary duty of loyalty during the representation, the plaintiff must allege and identify the source of the duty, that a breach occurred resulting in injury, and that

the breach proximately caused the injury.” Arden v. Forsberg & Umlauf, P.S., 189 Wn.2d 315, 323, 402 P.3d 245 (2017). Broadly stated, “[a]n act generally is a proximate cause of an injury if it produces the injury.“ Roemmich v. 3M Company, 21 Wn. App. 2d 939, 952, 509 P.3d 306 (2022). Here, however, Eppler alleges, and the trial court ruled, that the sentencing court’s error is a superseding cause and therefore severs the causal connection between Eppler’s tortious conduct and Stone’s injury.

In Roemmich, we set forth the legal principles that govern the superseding cause analysis as follows:

[W]hen a new, independent act breaks the chain of causation, it supersedes the original act as the proximate cause of the injury.

[Crowe v. Gaston, 134 Wn.2d 509, 519, 951 P.2d 1118 (1998)]. The Restatement of Torts defines “superseding cause” as “an act of a third person or other force which by its intervention prevents the actor from being liable for harm to another which his antecedent negligence is a substantial factor in bringing about.” RESTATEMENT (SECOND) OF TORTS § 440 (AM. LAW INST. 1965).

In determining whether an intervening act constitutes a superseding cause we consider “whether (1) the intervening act created a different type of harm than otherwise would have resulted from the actor’s negligence; (2) the intervening act was extraordinary or resulted in extraordinary consequences; [and] (3) the intervening act operated independently of any situation created by the actor’s negligence.” Campbell v. ITE Imperial Corp., 107 Wash.2d 807, 812-
