In re Isaacson, Jeffrey Mark, 2016PR00030
(One of multiple dispositions on this case)
Disposition Probation
Effective Date of Disposition 12/08/2017
End Date of Disposition 12/08/2018 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.
