Attorney Justin P. Cannon lost his license to practice law in California on Thursday, June 15, 2023. The California Supreme Court disbarred him for not filing a declaration of compliance with the State Bar Court, as he was ordered to do by a previous disciplinary ruling.

The case is entitled “In the Matter of Justin P. Cannon,” with case no. S279390.

In a notice of disciplinary charges dated April 19, 2022, it was stated that the State Bar of California charged attorney Justin P. Cannon with violating California rules by failing to file a required declaration of compliance with the clerk of the State Bar Court.

The notice of disciplinary charges states:

“Respondent failed to file a declaration of compliance with California Rules of Court, rule 9.20 in conformity with the requirements Of rule 9.20(c) with the clerk of the State Bar Court by November 23, 2021, as required by Supreme Court order in Case no. S269849, in willful violation of California Rules of Court, rule 9.20. A true and correct copy of the rule 9.20 order is attached hereto as Exhibit 1 and is incorporated by reference.”

Following the notice, an amended petition for disbarment was filed by the State Bar requesting the disbarment of the respondent after his failure to respond to the notice of disciplinary charges and failure to have the default set aside. The petition stated that the default was properly entered, and the notice of disciplinary charges was served on the attorney with proof of receipt. As a result of the default, the facts alleged in the notice of disciplinary charges have been deemed admitted, supporting a finding that Cannon violated statutes, rules, or court orders warranting the imposition of discipline. The State Bar of California determined that Cannon failed to comply with requirements to avoid a disbarment recommendation, leading the State Bar to recommend disbarment as required in such circumstances.

Consistent with this recommendation, the Supreme Court of California disbarred Cannon from practicing law.

The Disposition states:

“The court orders that Justin P. Cannon (Respondent), State Bar Number 289715, is disbarred from the practice of law in California and that Respondent’s name is stricken from the roll of attorneys. The respondent must comply with California Rules of Court, rule 9.20, and perform the acts specified in subdivisions (a) and (c) of that rule within 30 and 40 calendar days, respectively, after the date this order is filed. (Athearn v. State Bar (1982) 32 Cal.3d 38, 45 [the operative date for identification of clients being represented in pending matters and others to be notified is the filing date of this order].)”
