COURT OF APPEAL, FOURTH APPELLATE DISTRICT

DIVISION ONE

STATE OF CALIFORNIA

MICHAEL SISTI, D083817

Respondent,

v. (Super. Ct. No. 21FL009420S)

ERIN CALLAHAN,

Appellant.

APPEAL from orders of the Superior Court of San Diego County, James T. Atkins, Judge. Affirmed. Erin Callahan, in pro per, for Appellant. No appearance for Respondent.

Erin Callahan, who is self-represented on appeal, challenges the family court’s order denying her request for a domestic violence restraining order (DVRO) against her former boyfriend, Michael Sisti. Specifically, she asserts the court erred by excluding the testimony of two expert witnesses and by preventing her from presenting evidence of abuse that occurred before the denial of her previous request for a restraining order. Callahan also challenges the family court’s order imposing sanctions of $37,000 against her

under Family Code section 271.1 As we shall explain, we reject Callahan’s arguments and affirm the family court’s orders. FACTUAL AND PROCEDURAL BACKGROUND Callahan and Sisti lived together for several years and share one child. The couple separated in 2021, and in August of that year Sisti filed a petition for custody and support of their child. In December 2021, Callahan filed a request for a DVRO, which the court denied. On August 18, 2023, Callahan filed another request for a DVRO against Sisti, seeking protection for Callahan, the parties’ child, and Callahan’s two older children. The request was filed in the central San Diego division of the Superior Court, and not Chula Vista, where the custody case was pending. In the petition, Callahan alleged Sisti was stalking her and had been abusive in the past. In her request, she alleged that Sisti trespassed on her property in September 2021, which scared her children. Callahan also stated that in October 2022, she turned in her car lease because she feared Sisti had installed a tracking device on the car and during a subsequent custody exchange of their child, she thought he followed her to see what car she was driving. Finally, she asserted that in June and July of 2023, Sisti had stalked her social media accounts using “alias accounts.” The Chula Vista division of the family court issued a temporary restraining order (TRO) and set a hearing on the DVRO for September 7, 2023. On August 23, 2023, Sisti’s counsel filed a request for a firearm exemption from the temporary restraining order. In his declaration filed in support of the request, Sisti explained he was required to carry a firearm for his job as a customs officer with the Department of Homeland Security. Sisti

1 Subsequent undesignated statutory references are to the Family Code. 2 also explained that on December 7, 2022, Callahan had filed a request for order (RFO) seeking to modify child custody and visitation and in May 2023 had appeared ex parte requesting an evidentiary hearing on her RFO, which was scheduled for September 25–26, 2023, and October 19, 2023. Sisti also asserted Callahan had later withdrawn the RFO and that the court had

vacated the hearing dates as a result.2 At the September 7, 2023 hearing on Callahan’s request for the DVRO, Callahan was represented by counsel. During the hearing, Sisti’s counsel alleged Callahan was attempting to judge-shop by withdrawing her RFO and then filing a request for DVRO in San Diego. Counsel further argued he had issued discovery requests to Callahan in July, but she had failed to disclose the addresses of her proposed witnesses so that depositions could be scheduled, or respond to Sisti’s demand for expert witness information. Sisti’s counsel also asserted Callahan was attempting to relitigate findings that were made by the court at the time it denied her initial request for a DVRO in 2021, and Callahan’s new request for a DVRO did not allege any additional abusive conduct occurring after that denial. Sisti’s counsel requested the parties proceed with an evidentiary hearing on Callahan’s DVRO request, or alternatively that the court dissolve the TRO issued on August 23, 2023 and set a later evidentiary hearing date. Callahan’s counsel responded she was not ready to move forward with an evidentiary hearing. The court then indicated it would conduct the evidentiary hearing, or dissolve the TRO and Callahan could refile the request for a DVRO.

2 The appellant’s appendix Callahan submitted to this court is extremely limited, and does not include filings related to the RFO. The appendix also does not comply with the appellate record requirements set forth in California Rules of Court, rules 8.122 and 8.124. 3 Callahan’s counsel agreed to proceed with the evidentiary hearing and called one of Callahan’s experts, Barry Goldstein, to the stand. Sisti’s counsel objected based on Callahan’s failure to respond to his demand for expert witness information. The court then permitted Callahan’s counsel to question Goldstein. When asked for his qualifications, Goldstein responded he was “a domestic violence author, speaker, advocate, and expert witness.” After Callahan’s counsel asked Goldstein to refer to his report, Sisti’s counsel objected on the grounds that Goldstein had not been sufficiently qualified as an expert witness. The court agreed, finding the evidence of his qualifications was “insufficient at this point.” In response to the ruling, Callahan’s counsel stated she would move to her next witness. Before the next witness was called, the court ended the session, continued the evidentiary hearing to October 19, 2023, and denied a request by Sisti to dissolve the TRO. At the continued evidentiary hearing, Sisti’s counsel made a motion in limine to exclude testimony and evidence concerning events that occurred before the court denied Callahan’s previous request for a DVRO on December 23, 2021. Sisti’s counsel asserted the court had concluded Callahan was not a credible witness before denying her earlier request, and that it would be res judicata to relitigate the events that occurred before the denial. Callahan’s attorney responded that under section 3044, the court could consider any relevant evidence that occurred within the past five years,

4 so res judicata did not apply in this circumstance.3 She further asserted the prior denial had been entered without prejudice. The court sided with Sisti, and ruled it would “not hear any evidence or testimony regarding anything alleged to have occurred prior to December 23rd, 2021.” The court also found its earlier denial was made with prejudice, and that a minute order stating it was without prejudice was an error in the record. Callahan’s attorney then proceeded to call her second expert witness, Kate Amber. As with Goldstein, Sisti’s counsel objected, asserting Callahan had failed to respond to their demand for exchange of expert information and that Amber’s testimony should be excluded under People v. Sanchez (2016) 63 Cal.4th 665 (Sanchez) because Amber would rely solely on case-specific, hearsay testimony of Callahan. Callahan’s attorney responded she had provided Sisti’s counsel with a witness list before the September hearing, and that she had also provided him Amber’s report. In addition, Callahan’s counsel stated she was not prepared to address Sanchez and argued Sisti’s counsel should have raised the issue before the hearing. The court then tentatively ruled Amber’s testimony was inadmissible under Sanchez and Callahan could brief the issue if the hearing was not concluded that day.
