Opinion

IN THE OREGON TAX COURT REGULAR DIVISION Mandamus; Review Personal Income Tax

THERESA M. SEELEY, ) ) Plaintiff-Relator, ) TC 5488 v. ) ) ORDER DISMISSING PETITION FOR DEPARTMENT OF REVENUE, ) WRIT OF MANDAMUS AND WRIT OF ) REVIEW, AND DENYING Defendant. ) DEFENDANT’S MOTION TO DISMISS

This personal income tax matter is before the court on Relator’s “Petition for Writ of

Mandamus per ORS 34.120(2),” filed September 24, 2025, which the court alternatively

considers as a petition for a writ of review. Relator asks the court to order Defendant to take

various actions as to tax years beginning as early as 1992. (See, e.g., Rel’s Petition at 14

(seeking information return corrections for years 1992 through 2022 and beyond).) The court

concludes that these requested actions constitute five claims for orders requiring Defendant to (1)

pay or credit to Relator certain tax, penalty, and interest amounts, including correcting

information returns to support the payments or credits; (2) correct certain information returns in

support of Relator’s potential claims for retirement or other benefits; (3) temporarily stay

penalties and interest; (4) conduct an audit of Relator’s former employer, Portland Public

Schools (PPS); and (5) pay damages for harassment, fraud, and emotional distress.

On November 18, 2025, the court held a case management conference (CMC) and

ordered briefing to aid the court in addressing three issues before issuance of any writ. 1 First,

1 The court ordered the CMC and briefing to be conducted jointly for this case and for TC 5489, in which Relator filed a petition against PPS. Relator’s petition in TC 5489 is addressed by separate order, also issued today.

ORDER DISMISSING PETITION FOR WRIT OF MANDAMUS AND WRIT OF REVIEW, AND DENYING DEFENDANT’S MOTION TO DISMISS TC 5488 Page 1 of 15 whether Relator’s claims are within the court’s subject matter jurisdiction. See ORS 34.120(2)

(“The regular division of the Oregon Tax Court shall have jurisdiction in mandamus proceedings

in all cases within its jurisdiction as described in ORS 305.410 * * *.”). 2 Second, to the extent

that the court has subject matter jurisdiction over the claims, whether Relator has a plain, speedy,

and adequate remedy at law that precludes issuance of a writ of mandamus. See ORS 34.110

(“The writ shall not be issued in any case where there is a plain, speedy and adequate remedy in

the ordinary course of the law.”); State ex rel Portland Habilitation Center v. PSU, 353 Or 42,

60, 292 P3d 537 (2012) (upholding trial court’s pre-issuance dismissal of mandamus petition

based on determination that relator had a plain, speedy and adequate remedy available). Third,

how the court should proceed if the petition is viewed as one for writ of review. See CMC

Summary (Nov 18, 2025). Based on the parties’ responses to these issues, the court concludes

that it is required to dismiss the petition in its entirety.

As to the first issue--subject matter jurisdiction--the court applies the Oregon Supreme

Court’s framework in Sanok v. Grimes, concluding that this court lacks jurisdiction as to Claims

(2), (4), and (5) because relief under those claims would not affect Relator’s tax liability. Sanok

v. Grimes, 294 Or 684, 662 P2d 693 (1983). This conclusion requires the court to dismiss the

petition as to those three claims, regardless of whether the petition is construed as one for writ of

mandamus or for writ of review. However, Claim (1) is squarely within the court’s subject

matter jurisdiction, and the court is unable to determine whether Claim (3) is within its subject

matter jurisdiction. As to those two claims, dismissal on subject matter jurisdiction grounds is

not appropriate.

ORDER DISMISSING PETITION FOR WRIT OF MANDAMUS AND WRIT OF REVIEW, AND DENYING DEFENDANT’S MOTION TO DISMISS TC 5488 Page 2 of 15 Turning to the second issue, the court concludes that Relator has a plain, adequate, and

speedy remedy at law, namely appeal to the Magistrate Division, for the two remaining claims,

Claims (1) and (3). Therefore, construing the petition as one for writ of mandamus, the court

must dismiss those two claims.

Finally, the court concludes that, construed as a petition for writ of review as to the two

claims within its jurisdiction, the petition is untimely because it was not filed within 60 days

from the date of any “decision or determination” of Defendant as required by ORS 34.030(1).

This conclusion deprives the court of review jurisdiction as to Claims (1) and (3) and thus

requires dismissal of the petition in its entirety.

I. ISSUES

A. Whether this court has subject matter jurisdiction under ORS 305.410 to order the

actions Relator requests.

B. To the extent that the court has subject matter jurisdiction, whether Relator has a plain,

speedy, and adequate remedy at law such that issuance of any writ of mandamus is

precluded.

C. To the extent that the court has subject matter jurisdiction, whether the court should

issue a writ of review in lieu of a writ of mandamus.

II. ANALYSIS

A. Subject Matter Jurisdiction Under ORS 305.410

ORS 34.120(2) provides, in relevant part, that “[t]he regular division of the Oregon Tax

Court shall have jurisdiction in mandamus proceedings in all cases within its jurisdiction as

described in ORS 305.410 * * *.” Under Oregon Supreme Court case law, to determine

jurisdiction under ORS 305.410, this court undertakes a three-part analysis:

ORDER DISMISSING PETITION FOR WRIT OF MANDAMUS AND WRIT OF REVIEW, AND DENYING DEFENDANT’S MOTION TO DISMISS TC 5488 Page 3 of 15 “1. Identify the ‘subject matter of each claim.’ Sanok, 294 Or at 689 n 22.

“2. Determine whether any statute ‘expressly’ or ‘positively’ (id. at 692)

“a. Precludes jurisdiction in this court (see, e.g., ORS 305.410(1)(a)-(o) (listing provisions that ‘are not tax laws of this state’));

“b. Confers jurisdiction in this court (see, e.g., ORS 320.330 (providing for ‘appeals to the Oregon Tax Court’)); or
