UNPUBLISHED OPINION

STEVEN M. FINLAN, as the PERSONAL REPRESENTATIVE OF THE ESTATE OF ALEXANDER K. FINLAN; STEVEN M. FINLAN, individually, and HEATHER WILDER, a/k/a Heather Hazel Adele Wilder Wills, individually,

Appellants.

DÍAZ, J. — Herman Sedillo sued Alex Finlan for negligence following a car accident. The jury found Finlan 80 percent at fault. The court awarded damages to Sedillo in the amount of over $1.8 million. The Finlan estate challenges the award, claiming several of the court’s evidentiary rulings were in error. 1 We hold that the court abused its discretion in admitting evidence of Finlan’s juvenile conviction and his invocation of his Fifth Amendment rights. We vacate the verdict

1 For clarity, we hereafter refer to Alex Finlan as Finlan and to the Finlan estate as “the estate.”

and judgment, and remand the matter to the court for a new trial on liability only.

I. BACKGROUND

In December 2017, Finlan, then 16, was driving a Chevrolet S10 pickup truck westbound on South Skagit Highway, at the same time Sedillo was driving a Ford Fusion eastbound on the same highway. The two cars collided head-on. The parties dispute whether Finlan veered into the eastbound lane or whether Sedillo veered into westbound lane. Sedillo told police that Finlan had veered into his lane. Finlan could not remember what had happened. Both drivers left the scene by ambulance with serious injuries.

A sheriff’s deputy inspected the scene and found marijuana in the truck that Finlan had been driving. Finlan later pled guilty in juvenile court to an offense related to the discovery of the marijuana.

Finlan sued Sedillo’s employer and the case settled for an undisclosed amount. In November 2020, Sedillo sued Finlan, claiming Finlan had negligently caused the accident. Finlan died in April 2022, of unrelated causes. Sedillo amended his complaint to sue Finlan’s estate.

The estate moved in limine in pertinent part to exclude from evidence all references to “Finlan possessing, using, or being under the influence of marijuana,” and to his “criminal case for possession of marijuana,” including his invocation of the Fifth Amendment rights in response to some related questions. The court denied the motions.

Trial commenced on March 3, 2025. Both parties presented expert witness testimony opining that the other party had veered into the wrong lane. The jury

found Finlan 80 percent at fault for the collision. The estate timely appeals.

II. ANALYSIS

The estate claims that the court erred when it admitted evidence of Finlan’s “criminal case for possession of marijuana,” including his invocation of the Fifth Amendment rights. U.S. CONST. amend. V. The estate also assigns error to the court’s admission of evidence related to Finlan’s historic use of marijuana including at the time of the collision, an expert witness’s testimony thereto, and other rulings.

We agree with the estate that the court abused its discretion when it admitted evidence that Finlan (1) pled guilty to the possession of marijuana as a juvenile and (2) invoked the Fifth Amendment when questioned about whether he possessed and sold marijuana. Because these errors alone warrant reversal, we do not address the remaining assignments of error. A. Finlan’s Juvenile Conviction ER 609 governs impeachment, i.e., attacking the credibility of a witness, by evidence of the conviction of a crime. The general rule is that, for impeachment “in a criminal or civil case, evidence that the witness has been convicted of a crime shall be admitted . . . only if the crime (1) was punishable by . . . imprisonment in excess of 1 year . . ., and the court determines that the probative value of admitting this evidence outweighs the prejudice to the party against whom the evidence is offered, or (2) involved dishonesty or false statement, regardless of the punishment.” ER 609(a).

As to the former, “[e]vidence of prior felony convictions is generally inadmissible against a defendant because it is not relevant to the question of guilt

yet very prejudicial, as it may lead the jury to believe the defendant has a propensity to commit crimes.” State v. Hardy, 133 Wn.2d 701, 706, 946 P.2d 1175 (1997). There is no evidence in the record that Finlan was convicted of a felony and, thus, ER 609(a)(1) does not justify the admission of Finlan’s conviction. 2 As to the latter, “[d]rug convictions are not crimes of ‘dishonesty or false statement’ like perjury or criminal fraud” and, thus, ER 609(a)(2) does not apply either. Id. at 707 (footnote omitted).

Juvenile adjudications, moreover, are “generally not admissible” pursuant to ER 609(d). There is no provision allowing such evidence in a civil case. In a criminal case, “[t]he court may . . . allow [such] evidence . . . of a witness other than the accused if conviction of the offense would be admissible to attack the credibility of an adult and the court is satisfied that admission in evidence is necessary for a fair determination of the issue of guilt or innocence.” Id.

Even in such circumstances, the rule requires “a positive showing that the prior juvenile record is necessary to determine guilt,” i.e., an “indication of special reasons favoring admissibility” overcoming the “the general presumption [] that juvenile adjudications are inadmissible.” State v. Gerard, 36 Wn. App. 7, 12, 671 P.2d 286 (1983).

In Gerard, the defendant/proponent of the evidence “did not give any reasons for admissibility beyond general impeachment of the witness’ credibility.”

2 Sedillo asked for this information in discovery, the estate objected and later

claimed it could not determine this information because Finlan’s juvenile file was sealed. Regardless, Sedillo brought no motion to compel or unseal the information, and there is no suggestion Finlan was convicted of a felony.

Id. “The burden was on [the proponent] to present reasons other than impeachment to demonstrate that the evidence was ‘necessary for a fair determination’” of guilt. Id. (emphasis added) (quoting State ex rel. Carroll v. Junker, 79 Wn.2d 12, 20, 482 P.2d 775 (1971)).

We review ER 609 rulings for an abuse of discretion. State v. Bankston, 99 Wn. App. 266, 268, 992 P.2d 1041 (2000). A court abuses its discretion when a decision is manifestly unreasonable or based on untenable grounds or untenable reasons. In re Marriage of Katare, 175 Wn.2d 23, 35, 283 P.3d 546 (2012). While this standard “provides great deference to the trial court’s evidentiary rulings, it does not immunize them.” State v. Broussard, 25 Wn. App. 2d 781, 789, 525 P.3d 615 (2023).

After the collision, Finlan sued Sedillo’s employer, the United States Department of Agriculture, under the Federal Tort Claims Act, Title 28, chapter 171 (Sec. 2671 et seq.) Aug. 2, 1946, ch. 753, title IV, 60 Stat. 842, because Sedillo had been travelling for his work as a meat inspector at the time of the crash. The government deposed Finlan as part of the lawsuit. During the deposition, Finlan testified that he had been charged and pled guilty to some crime or offense related to the discovery of the marijuana in the truck at the time of the accident.
