In re O'Brien, Vincent J., 2015PR00023
Disposition Suspension for a specified period of time and until further order of the Court
Effective Date of Disposition 03/20/2017
End Date of Disposition
Definition of Disposition A suspension until further order of the Court reflects a determination that the lawyer has engaged in misconduct and that the misconduct warrants an interruption of the lawyer's authority to practice law during the suspension period, which is a fixed period of time identified in the Supreme Court's order and until the lawyer has demonstrated rehabilitation, good character, and current knowledge of the law in a subsequent reinstatement case. The lawyer is not authorized to practice law during the period of the suspension.
Case Summary Mr. O’Brien, who was licensed in 1987, was suspended for two years and until further order of the Court and until he makes certain restitution. He neglected five different personal injury cases and failed to communicate with clients. He also failed to pursue a client’s custody case and, after termination, he did not return the client’s file, provide a billing statement or refund the unearned portion of the fee.

(One of multiple dispositions on this case)
Disposition Probation
Effective Date of Disposition 02/13/2017
End Date of Disposition No disposition end date scheduled at this time. Probation continues until compliance with probationary condition(s).
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 O'Brien, Vincent J., 2014PR00024
(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 02/13/2017
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. O’Brien, who was licensed in 1987, was suspended for nine months, with the suspension stayed after four months by a twelve-month period of conditional probation. He did not diligently pursue two personal injury matters and a pending estate matter and he did not inform his clients of, or respond to their requests for information about, the status of their cases. Also, in one of the personal injury matters, he misrepresented the actual status of the case to the client and, in the estate matter, he did not provide his client with an accounting for more than four months after the client’s request. The suspension is effective on October 13, 2016.
