Sabrina Zunker, Pro Se
*Sitting by assignment of the Chief Justice under provisions of Colo. Const. art. VI, § 5(3), and § 24-51-1105, C.R.S. 2025. ¶1 In this post-dissolution of marriage proceeding involving Derek
Zunker (father) and Sabrina Zunker (mother), mother appeals from
the district court’s adoption of the magistrate’s order enjoining her
from filing additional pro se motions or requests for relief. We
affirm.
I. Background
¶2 The parties’ three-year marriage ended in 2012. They are the
parents of one child.
¶3 The parties originally shared equal parenting time. In
November 2017, a district court magistrate awarded father sole
decision-making responsibility and modified parenting time, with
father becoming the majority-time parent. In October 2020,
mother’s attorneys withdrew from the case.
¶4 Since October 2022, mother has engaged in a persistent
campaign of filing pro se motions and other requests for relief with
the district court. Over that time, mother’s pro se pleadings
included:
• two motions for the district court magistrate to recuse;
• a motion to modify child support;
1 • two motions seeking to lift existing orders limiting her
right to record father and other third parties and lift
limitations on her right to communicate with third
parties about the case;
• multiple motions to stay court orders and continue court
proceedings;
• two separate motions for “clarification” of prior court
orders;
• multiple motions to dismiss pleadings filed by father;
• multiple motions seeking to compel father and other
third parties to produce documents; and
• nine separate petitions for district court review of various
magistrate orders.
¶5 In all, mother filed over twenty-five motions and other requests
for relief between October 2022 and September 2024.
¶6 In response to mother’s barrage of pro se pleadings, in
January 2024, father moved to enjoin her from filing additional
pleadings as a pro se party. After holding a hearing, a district court
magistrate granted father’s motion and prohibited mother from
2 filing any further motions or other requests for relief without an
attorney.
¶7 The magistrate cited mother’s numerous filings and found that
her conduct had been “egregious and harassing” because she had
been “us[ing] the judicial process to disrupt [father]’s life” and was
causing him to incur significant legal costs. Critically, the
magistrate found that most of mother’s pro se filings did “not
contain legal authority, misstate[d] facts, and [were] repetitious.”
Similarly, the magistrate observed that mother “simply appeals
every [m]agistrate [o]rder [to the district court] as a matter of
course,” and that the arguments in her multiple petitions for review
were “often unclear, overlapping, circular, and recycled.”
¶8 The magistrate also found that mother’s numerous pro se
filings took “significant time for the clerk’s office and [the]
courtroom staff to process” and consequently “interfere[d] with the
interests of other litigants and the public’s access to the court
through repetitive and nonsensical filings.” For example, the
magistrate cited mother’s July 21, 2024, “Motion for Clarification,”
which contained thirty-eight exhibits.
3 ¶9 Mother petitioned for district court review, and the reviewing
district court judge adopted the magistrate’s order. In support, the
reviewing district court judge made additional findings, including
the observation that “none of [mother’s] substantive motions ha[d]
been granted by the magistrate or the district court.” The district
court also found, based on mother’s recent sworn financial
statement, that she could afford an attorney to represent her.
II. Order Enjoining Pro Se Filings
A. Standards of Review and Applicable Law
¶ 10 Our review of a district court’s order adopting a magistrate’s
decision is effectively a second layer of appellate review. In re
Marriage of Sheehan, 2022 COA 29, ¶ 22. We must accept the
magistrate’s factual findings unless they are clearly erroneous,
meaning that they have no support in the record. In re Marriage of
Young, 2021 COA 96, ¶ 8. However, we review de novo questions of
law. Sheehan, ¶ 22.
¶ 11 “Our constitution guarantees every person access to the courts
of this state.” Karr v. Williams, 50 P.3d 910, 913 (Colo. 2002) (citing
Colo. Const. art. II, § 6). However, the right to access the courts is
not absolute and must be balanced against the need to protect the
4 judicial system from abuse. Id. at 913-14. Therefore, a court may
exercise its discretion to impose a narrowly tailored limitation on a
party’s ability to pursue litigation when that limitation does not
place an unreasonable burden on a party’s right to access the
courts. See id. at 914; Bd. of Cnty. Comm’rs v. Winslow, 706 P.2d
792, 794 (Colo. 1985).
¶ 12 The supreme court has considered the following actions as
hampering the efficient administration of justice to an intolerable
degree, such that enjoining a litigant from affirmatively proceeding
pro se was warranted:
(1) filing a multitude of meritless claims;
(2) bringing claims that appear to be aimed at harassing
opposing parties; or
(3) using procedures to expand litigation in ways that strain
judicial resources.
GHP Horwath, P.C. v. Kazazian, 2024 CO 8, ¶ 67.
¶ 13 Given the important constitutional rights involved, we review
de novo a restriction on a party’s right to file pro se pleadings. See
Lewis v. Colo. Rockies Baseball Club, Ltd., 941 P.2d 266, 271 (Colo.
5 1997); Morris-Schindler, LLC v. City & County of Denver, 251 P.3d
1076, 1084 (Colo. App. 2010).
B. Discussion
¶ 14 As best as we can discern, mother contends that district court
erred by adopting the magistrate’s order enjoining her from filing
additional pro se motions because she was subsequently successful
in an appeal arising from one of her pro se motions. We reject this
argument. In In re Marriage of Zunker, slip op. at ¶ 1 (Colo. App.
No. 24CA1180, May 1, 2025) (not published pursuant to C.A.R.
35(e)), mother appealed the district court’s adoption of a
magistrate’s order that had denied, under the doctrine of res
judicata, mother’s pro se request to lift prior limitations that had

1076, 1084 (Colo. App. 2010).
B. Discussion
¶ 14 As best as we can discern, mother contends that district court
erred by adopting the magistrate’s order enjoining her from filing
additional pro se motions because she was subsequently successful
in an appeal arising from one of her pro se motions. We reject this
argument. In In re Marriage of Zunker, slip op. at ¶ 1 (Colo. App.
No. 24CA1180, May 1, 2025) (not published pursuant to C.A.R.
35(e)), mother appealed the district court’s adoption of a
magistrate’s order that had denied, under the doctrine of res
judicata, mother’s pro se request to lift prior limitations that had
been placed on her right to record father and communicate with
third parties. Another division of this court ultimately reversed the
district court’s order and remanded for further proceedings because
the magistrate had misapplied the doctrine of res judicata given
that the doctrine only bars a party from relitigating claims in a
separate legal proceeding, as opposed to within the same legal
proceeding. Id. at ¶¶ 17, 19, 22, 24.
6 ¶ 15 But for multiple reasons, we reject mother’s suggestion that
the resolution of that appeal in her favor demonstrates that her pro
se filings have been meritorious, and therefore, the order enjoining
her from filing pro se motions was in error.
¶ 16 To start, when enjoining mother from filing pro se, the
magistrate and the reviewing district court judge did not have the
benefit of the division’s opinion in Zunker, which was issued after
both the magistrate’s order and the district court’s review.
Therefore, the later resolution of Zunker in mother’s favor could not
have been considered by the magistrate and district court.
¶ 17 However, even if we consider the outcome of Zunker, we
disagree that mother’s success in that appeal means that she has
presented persuasive and meritorious arguments. Taking judicial
notice of this court’s file in Zunker, see Harriman v. Cabela’s Inc.,
2016 COA 43, ¶ 64, we observe that at no point in her appellate
briefing did mother argue that res judicata did not apply to orders
within the same proceeding, which was the rationale upon which
the division in Zunker reversed and remanded for further
proceedings. See Zunker, No. 24CA1180, slip op. at ¶¶ 17, 19, 22,
7 24. Instead, mother had argued that the application of the doctrine
of res judicata was a violation of her constitutional rights.
¶ 18 Moreover, while the division in Zunker remanded the case for
further proceedings because the magistrate had improperly applied
res judicata, that division otherwise expressed no opinion as to the
merits of mother’s underlying requests for relief. See id. at ¶¶ 19-
24.
¶ 19 Finally, although mother may have prevailed in Zunker, we
observe that she has not even attempted to justify her numerous
other pro se filings involving matters outside the scope of that
appeal, which were also cited by the magistrate as justifying an
order enjoining her from proceeding pro se. Our review of mother’s
numerous other pro se motions and requests for relief supports the
magistrate’s conclusion that her filings were often meritless, given
that they did not contain relevant legal authority, were repetitious
and circular, and otherwise contained numerous arguments
recycled from previously denied motions. See Kazazian, ¶ 67.
¶ 20 Similarly, we find record support for the magistrate’s
observation that mother’s numerous and lengthy filings were
consuming a disproportionate amount of court resources. See id.
8 For example, a petition for district court review filed by mother on
January 8, 2024, contained over seventy exhibits spanning
approximately 2,200 pages.
¶ 21 Thus, we perceive no error in the magistrate’s decision to
enjoin mother from filing additional pro se motions. See id.
III. Mother’s Other Contentions
¶ 22 With little explanation and minimal legal authority, mother
presents a laundry list of additional claimed errors that are
unrelated to the magistrate’s order enjoining her from filing pro se,
and which largely consist of her grievances against husband, the
magistrate, and the district court.
¶ 23 To start, it is not clear to us what order or orders mother is
even attempting to appeal, as her lengthy list of alleged errors spans
multiple years of the parties’ litigation and even references other
civil proceedings. And while mother suggests that the magistrate
has erred by not “reconsidering” prior evidence, testimony, and
court orders, she has not directed us to any motion and resulting
final order in which she requested such relief. See In re Marriage of
Evans, 2021 COA 141, ¶ 11 (“Our jurisdiction is limited to review of
final, appealable judgments or orders.”).
9 ¶ 24 Moreover, mother’s protracted list of alleged errors violates
C.A.R. (a)(7)(A), requiring a separate heading for each issue as to
the applicable standard of review and issue preservation, C.A.R.
28(a)(7)(B), requiring “a clear and concise discussion of the grounds
upon which the party relies in seeking a reversal” of an order, and
C.A.R. 28(a)(8), requiring an appellant to identify “the precise relief
sought” on appeal.
¶ 25 Lastly, to the extent that we can discern her contentions of
error, we decline to address them given that they are largely
undeveloped and presented without supporting legal authority. See
In re Marriage of Zander, 2019 COA 149, ¶ 27 (appellate court will
not consider an argument not supported by any meaningful legal
analysis), aff’d, 2021 CO 12; see also Antolovich v. Brown Grp.
Retail, Inc., 183 P.3d 582, 604 (Colo. App. 2007) (declining to review
appellants’ arguments because they reflected a “shotgun approach”
and set forth “little analysis”). We also do not address new or
expanded arguments made for the first time in a reply brief. See In
re Marriage of Dean, 2017 COA 51, ¶ 31.
10 IV. Appellate Attorney Fees
¶ 26 Asserting that mother’s appeal lacks substantial justification,
father requests an award of his appellate attorney fees under
section 13-17-102, C.R.S. 2025. An appeal lacks substantial
justification when it is substantially frivolous, substantially
groundless, or substantially vexatious. § 13-17-102(9)(a). However,
mother is pro se, and therefore, before imposing an award of
appellate attorney fees under that statute, we must conclude that
she clearly knew or reasonably should have known that her claims
lacked substantial justification before we may award father attorney
fees. § 13-17-102(6).
¶ 27 We view at least portions of mother’s appeal as lacking
substantial justification, especially given her failure to follow the
appellate rules when asserting numerous, largely undeveloped
contentions of error in a disjointed, shotgun-style pleading. See
Antolovich, 183 P.3d at 604; C.A.R. 28(a)(7), (8). But we are not
convinced that mother clearly knew or reasonably should have
known that all or any portion of her appeal lacked substantial
justification. § 13-17-102(6).
11 ¶ 28 Mother is now on notice of her obligation to comply with the
appellate rules in any future appellate proceedings and of the
potential consequences if she does not, including dismissal and the
potential for sanctions. See C.A.R. 38; § 13-17-102; Martin v.
Essrig, 277 P.3d 857, 862 (Colo. App. 2011) (authorizing sanctions
for frivolous appeals).
¶ 29 Given our disposition, father is entitled to an award of his
appellate costs. See C.A.R. 39(a)(2).
V. Disposition
¶ 30 The order is affirmed.
