The disbarred lawyer is not authorized to practice law during the period of the disbarment on consent and may not return to the practice of law unless and until the lawyer 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 three years after the effective date of the disbarment on consent.
Case Summary Mr. Mateas, who was licensed in 1982, was disbarred on consent. He was convicted in Kane County of reproducing child pornography. He was sentenced to a four-year prison term and must register for life as a sex offender.

(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 03/19/2003
End Date of Disposition 03/19/2004
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. Mateas, who was licensed in 1982, was suspended for three years and until further order of Court, with the suspension stayed after the first year by a permanent period of probation with conditions. He was convicted in state court of attempted possession of child pornography.

Disposition Probation
Effective Date of Disposition
End Date of Disposition Probationary condition(s) continue.
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.
