In re Denigan, Joseph E., 2025PR00056
Disposition Suspension for a specified period of time and until further order of the Court
Effective Date of Disposition 01/15/2026
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. Denigan was licensed to practice law in Missouri in 1985 and in Illinois in 1986. In March 2025, the Supreme Court of Missouri indefinitely suspended him, with no leave to file for reinstatement for six months, after he pled guilty to two felony counts of driving while intoxicated. The Supreme Court of Illinois imposed reciprocal discipline and suspended him for six months and until further order of the Court. 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.
