In re Mahon, Edward James, 2010PR00068
Disposition Disbarment
Effective Date of Disposition 09/26/2011
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. Mahon, who was licensed in 1978, was disbarred. He misappropriated $5,000 in client settlement funds, engaged in the unauthorized practice of law by continuing to represent clients after he had been removed from the Master Roll of Attorneys for failing to register, did not cooperate with the ARDC investigation into his misconduct, and failed to appear at his disciplinary hearing.

Disposition Suspension for a specified period of time and until further order of the Court. Suspension stayed in whole.
Effective Date of Disposition 09/27/2005
End Date of Disposition 09/27/2005
Definition of Disposition The Supreme Court may order that a suspension be stayed in whole, typically in connection with an order of probation. A stay defers the suspension as long as the lawyer complies with probationary conditions. If the lawyer successfully completes probation, the lawyer is not actually suspended during any portion of the stayed suspension. Under those circumstances, the stayed suspension does not affect the authority of the lawyer to practice law and the lawyer may practice law during the stayed suspension. If the Court determines that the lawyer has failed to comply with probationary conditions, the Court may vacate the stay and may require that the lawyer actually serve the full suspension.
Case Summary Mr. Mahon, who was licensed in 1978, was suspended for one year and until further order of the Court, with the entire suspension stayed pending completion of a two-year period of probation with conditions necessary to monitor continuing treatment. He was convicted in state court of misdemeanor telephone harassment and disorderly conduct, which took place during a period when a medical condition was uncontrolled. In addition, he failed to report his conviction to the ARDC.

Disposition Probation
Effective Date of Disposition 09/27/2005
End Date of Disposition 09/27/2007 Probationary condition(s) satisfied.
Definition of Disposition Probation reflects a determination that the lawyer has engaged in misconduct, but also a finding that the lawyer may continue to practice law pursuant to specified conditions under ARDC supervision without posing a risk to the public, profession, or courts. As a result, the lawyer may continue to practice law during the period of probation, subject to the conditions imposed by the Court. Probation may be ordered for a specified period of time or for a specified period of time and until further order of the Court. Probation may be ordered in conjunction with a suspension, which may be stayed in whole or in part. A stay defers that portion of the suspension as long as the lawyer complies with probationary conditions. If the lawyer successfully completes probation, the lawyer is not actually suspended during any portion of the stayed suspension.
