In re Mills, Daniel Cass, 2021PR00099
Disposition Reinstated With Conditions
Effective Date of Disposition 03/21/2023
End Date of Disposition 03/20/2025 Condition(s) satisfied.
Definition of Disposition Reinstatement reflects the determination of the Supreme Court that a lawyer who was disbarred, disbarred on consent or suspended until further order of the Supreme Court has demonstrated in a subsequent reinstatement case his or her rehabilitation, good character, and current knowledge of the law to be reinstated, subject to conditions that address issue(s) that arose in the reinstatement case. An order of reinstatement with conditions reinstates the lawyer's license to practice law, but imposes conditions upon the lawyer's practice of law. Upon the determination that the petitioner has established compliance with conditions, the conditions are terminated. If the petitioner does not comply with the conditions, the Court may deny the reinstatement petition.

The lawyer is not authorized to practice law during the period of the suspension.
