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 No. 88714-9-I

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.

-2- No. 88714-9-I

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.

-3- No. 88714-9-I

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

-4- No. 88714-9-I

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.
