In re Hamill, Mark A., 2021PR00016
Disposition Suspension for a specified period of time and until further order of the Court
Effective Date of Disposition 01/20/2022
End Date of Disposition
Definition of Disposition A suspension until further order of the Court reflects a determination that the lawyer has engaged in misconduct and that the misconduct warrants an interruption of the lawyer's authority to practice law during the suspension period, which is a fixed period of time identified in the Supreme Court's order and until the lawyer has demonstrated rehabilitation, good character, and current knowledge of the law in a subsequent reinstatement case. The lawyer is not authorized to practice law during the period of the suspension.
Case Summary Mr. Hamill, who was licensed in 1991, was suspended for three years and until further order of the Court and until he makes restitution to his former client. He failed to act with reasonable diligence in seeking a patent application for a client, he ignored the client's attempts to reach him and then made false statements to the client about the status of her matter, he failed to return $2,975 in fees he had not earned, and he did not cooperate with a disciplinary investigation. A suspension until further order of the Court is an indefinite suspension which requires the suspended lawyer to petition for reinstatement after the fixed period of suspension ends. Reinstatement is not automatic and must be allowed by the Supreme Court of Illinois following a hearing before the ARDC Hearing Board.
