Disposition Disbarment
Effective Date of Disposition 09/20/2011
End Date of Disposition No disposition end date scheduled at this time. Discipline continues until further order of the Court.
Definition of Disposition Disbarment is a determination that the lawyer has engaged in misconduct warranting the most serious sanction. The disbarred lawyer is not authorized to practice law during the period of the disbarment and may not return to the practice of law unless and until he or she has demonstrated his or her rehabilitation, good character, and current knowledge of the law in a subsequent reinstatement case, which may not be filed until five years after the effective date of the disbarment.
Case Summary Mr. O’Sullivan was licensed in Missouri in 1981 and in Illinois in 1982. He was disbarred in Missouri for engaging in the unauthorized practice of law while he was suspended, failing to comply with continuing legal education requirements, not filing state tax returns, and not cooperating with the disciplinary authority. The Supreme Court of Illinois imposed reciprocal discipline and disbarred him.
