In re Corbett, John J., 2012PR00056
(One of multiple dispositions on this case)
Disposition Probation
Effective Date of Disposition 03/16/2014
End Date of Disposition 03/16/2016 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.
In re Corbett, John J., 2012PR00056
(One of multiple dispositions on this case)
Disposition Suspension for a specified period of time and until further order of the Court. Suspension stayed in part.
Effective Date of Disposition 10/16/2013
End Date of Disposition 03/16/2014
Definition of Disposition The Supreme Court may order that, following a suspension, a further period of suspension be stayed, typically in connection with an order of probation. A stay defers the further suspension period 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. Corbett, who was licensed in 1981, was suspended for one year and until further order of the Court, with all but the first five months stayed by a two-year period of probation. As a result of poor bookkeeping and his failure to properly reconcile his trust account, over a four-year period, he converted an aggregate of $148,545.70 in settlement funds belonging to clients and medical lienholders from 13 different matters. The suspension is effective on October 16, 2013.
