(One of multiple dispositions on this case)
Disposition Suspension for a specified period of time and until further order of the Court
Effective Date of Disposition 05/19/2008
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. Mangan, who was licensed in 1982, was suspended for two years and until further order of the Court. He pled guilty to eavesdropping, in that he knowingly and intentionally used an unlawful eavesdropping device for the purpose of recording a conversation of a female law firm associate, without her consent, and to unauthorized videotaping, in that he knowingly and without her consent videotaped under the clothing worn by the female associate for the purpose of viewing her undergarments, by hiding recording devices in locations throughout the firm, including a women’s restroom. He was suspended on an interim basis on August 1, 2006.
