OPINION AND ORDER

Plaintiffs Ashlee Hall and Hall Law Group, PLLC, allege that Defend- ants Christopher Marston, Diana Mullins, Exemplar Law, LLC, and Exem- plar Companies, PBC, conspired to deny Ms. Hall access to her legal clients after she left Exemplar Law, and allege various federal and state law causes of action against the Defendants as a result.

Exemplar Law and Exemplar Companies (collectively “Exemplar”) have filed a counterclaim against Ms. Hall and Hall Law alleging breach of con- tract, malicious interference with contractual relations, and breach of fiduci- ary duty. Dkt. 19. Ms. Hall moves to dismiss Exemplar’s counterclaims. Dkt. 28. The Court will first consider the motion to dismiss Ms. Hall’s claims against Mr. Marston and Ms. Mullins, and then Ms. Hall’s motion to dismiss Exemplar’s claims against both Hall Law and her.

No. 25-cv-421

The Court finds that Ms. Hall’s complaint states claims against both Mr. Marston and Ms. Mullins and denies their motion to dismiss. Dkt. 15. The Court also finds that Exemplar’s counterclaim does not state a claim upon which relief could be granted against Hall Law and does not state a claim for either breach of contract or malicious interference with contract against Ms. Hall. But Exemplar properly asserts a counterclaim against Ms. Hall for breach of fiduciary duty. The Court therefore grants in part and denies in part Ms. Hall’s motion to dismiss. Dkt. 28. Exemplar may amend its counter- claims to cure the deficiencies outlined in this opinion by February 27, 2026. If it does not do so by that date, this order will become final. Ms. Hall alleges that she joined Exemplar as its head of tax law in Feb- ruary 2025. Dkt. 2 at 2. As part of her employment agreement, Exemplar and Ms. Hall agreed that Ms. Hall’s pre-existing clients were to continue to be represented by Ms. Hall as part of her personal book of business, and she continued to be those clients’ attorney of record before the IRS. /d. at 3. Prior to her employment, Ms. Hall had established accounts with legal and tax soft- ware providers Clio and PitBullTax that she used to maintain and manage client matters, communications, contacts, and assorted confidential infor- mation. /d. Ms. Hall elected to continue using her existing Clio and Pit- BullTax accounts to service her pre-existing client base upon her employment by Exemplar. /d. Ms. Hall alleges that she never received new accounts or sign-in information for Clio or PitBullTax from Exemplar and continued to use her personal accounts licensed to Hall Law and her. /d. at 4. Ms. Hall also states that she never provided her Clio login information to Exemplar or any Exemplar employees but shared her login credentials to PitBullTax with Ms. Mullins “to change billing information . . . and add requisite additional li- censes.” Jd. Ms. Hall resigned from Exemplar in July 2025, less than five months after she joined the firm, citing Exemplar’s failure to provide her with

“operational and staffing support” to manage a tax law division. Jd. She al- leges that after her resignation, Exemplar employees, including Ms. Mullins, “gained unauthorized access to [her] C[lio] and PitBullTax accounts and changed [her] login credentials to that of Exemplar’s CEO Mr. Marston.” Jd. at 4, 15. Clio and PitBullTax subsequently refused to restore Ms. Hall’s access to the accounts without either a court order or written agreement between her and Exemplar. /d. at 5. Ms. Hall then sent Mr. Marston a cease-and-desist letter to restore her access to the accounts; Mr. Marston responded by threat- ening legal action against Ms. Hall. /d. at 19-20. Ms. Hall alleges that she “ex- perienced severe anxiety, fear, stress, panic, nervousness, concern, and des- peration” along with “severe sleep deprivation and mental anguish” due to her inability to conduct her business and represent her clients because of her exclusion from her Clio and PitBullTax accounts. Jd. at 15-16. Ms. Hall alleges that Defendants violated the Stored Communications Act when they gained unauthorized access to Ms. Hall’s Clio and PitBullTax accounts and “obtained [Ms. Hall’s] confidential, proprietary, and sensitive business records.” Jd. at 30-32. Ms. Hall also claims that the Defendants en- gaged in conversion of her property under Oklahoma law, id. at 35-37, and engaged in a conspiracy to convert her property, éd. at 37-38. Ms. Hall likewise alleges that Mr. Marston and Exemplar violated the Computer Fraud and Abuse Act. /d. at 32-35. She also claims that Mr. Mars- ton and Exemplar tortiously interfered with her contracts and business rela- tions, zd. at 38-41, tortiously interfered with her prospective economic ad- vantage, zd. at 41-43, invaded her privacy, éd. at 43-44, and intentionally in- flicted emotional distress upon her, id. at 44-48. Ms. Hall also requests the Court grant her an injunction and declaratory relief confirming that she is the legal owner of the Clio and PitBullTax accounts at issue, order all Defendants to cease accessing her accounts or using any information gleaned from those accounts, and produce a list of information that the Defendants gleaned or modified from the accounts. /d. at 49-51.

No. 25-cv-421 Mr. Marston and Ms. Mullins move to dismiss Ms. Hall’s claims against them, arguing they are immune from personal liability under Okla- homa law because they are employees of Exemplar, and as employees, they assert they are not liable to Ms. Hall because their alleged actions were on Exemplar’s behalf. Dkt. 15. Neither Ms. Mullins nor Mr. Marston argues that the substance of Ms. Hall’s complaint does not plead claims for relief. Instead, they each argue they are immune from liability. Ms. Mullins states that she cannot be held individually liable on any allegation because any action she took was “at Mr. Marston’s direction” and for neither personal gain nor to Exemplar’s detri- ment. Dkt. 15 at 4 (emphasis in original). She cites multiple cases to support her position, including Martin v. Johnson, 1998 OK 127, J 28, 975 P.2d 889, 895 (regarding the liability of a school district) and Benshoofy. Niles, 2016 OK CIV APP 57, J 21, 380 P.3d 902, 907 (regarding the liability of a sheriff).? But the cases Ms. Mullins cites to support her immunity are inapposite. The cited cases involved employees of Oklahoma public entities whose personal tort li- ability is limited by the Oklahoma Governmental Tort Claims Act.’ Ms. Mul- lins does not cite to a single case or provision of Oklahoma law stating that an

> Both Ms. Mullins and Mr. Marston base their arguments for immunity in Okla- homa law. Insofar as the Court finds that they are not immune from Ms. Hall’s claims under Oklahoma law, Ms. Hall has also levied federal claims against both defendants. Dkt. 2. Ok- lahoma law cannot grant immunity from a federal statute, so even if Ms. Mullins and Mr. Marston were immune under Oklahoma law, that immunity would not stretch to Ms. Hall’s claims under the Stored Communications Act and the Computer Fraud and Abuse Act. Doe vy. Dynamic Physical Therapy, LLC, No. 25-180, 2025 WL 3506945, at *1 (U.S. Dec. 8, 2025) (holding “a State has no power to confer immunity from federal causes of action.”). Neither party has given the Court any alternative rationale for why they would be immune from Ms. Hall’s federal claims. 3 Ms. Mullins and Mr. Marston argue that they have not argued the applicability of the OGTCA to this action. Dkt. 31 at 3 n.1.
