On Thursday, July 17, 2025, the New York Supreme Court, Appellate Division, First Judicial Department granted William O’Brien’s motion for reinstatement as an attorney and counselor-at-law in the State of New York. The decision marks the end of O’Brien’s suspension, which had been in place since November 10, 2009.
The case is entitled “In the Matter of William O’Brien,” with case no. 2025-03216.
O’Brien faced suspension due to non-compliance with Judiciary Law Section 468-a. This law requires attorneys to meet certain registration or other professional obligations. The original court order barred O’Brien from practicing law in New York until further notice from the court.
The reinstatement follows O’Brien’s compliance with Judiciary Law Section 468-a, which he fulfilled on or about May 23, 2025.
After reviewing his motion and related documents, the court determined that O’Brien met the requirements for reinstatement. The court’s order took effect immediately, allowing O’Brien to resume his legal practice in New York.
According to the filing, Mr. O’Brien acquired his law license in New York in 1996.
