In re Mayster, Larry S., 2015PR00072
(One of multiple dispositions on this case)
Disposition Suspension for a specified period. Suspension stayed in part.
Effective Date of Disposition 10/13/2016
End Date of Disposition 11/12/2016
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. Mayster, who was licensed in 1955, was suspended for six months, with the suspension stayed after thirty days by a six-month period of conditional probation. He mismanaged approximately $800 in settlement proceeds belonging to third-party lien holders while handling a personal injury matter and failed to maintain complete records for his client trust account. The suspension is effective on October 13, 2016.
In re Mayster, Larry S., 2015PR00072
(One of multiple dispositions on this case)
Disposition Probation
Effective Date of Disposition 09/22/2016
End Date of Disposition 05/02/2017 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 Mayster, Larry S., 99CH0059
Disposition Censure
Effective Date of Disposition 05/24/2002
End Date of Disposition Not Applicable. Censures and reprimands do not affect the authority of the lawyer to continue to practice law.
Definition of Disposition A censure reflects a determination that the lawyer has engaged in misconduct, but that the violation is not so serious to warrant a sanction that would affect the lawyer’s authority to continue to practice law. As a result, censure does not affect the authority of a lawyer to continue to practice law.
Case Summary Mr. Mayster, who was licensed in 1955, was censured. He mismanaged the settlement funds of two different clients. At the time, he did not have a client trust account and routinely commingled client funds and his own funds in a single business operating account.
