A Manhattan real estate attorney and former law firm associate has been suspended from practicing law after fabricating an opposition brief in the midst of appellate litigation, constructing a fake chain of emails supposedly exchanged with opposing counsel, and telling a series of other work-related lies to the partner with whom he was working.

Dennis McCoobery, admitted to the state bar in 1998, has been suspended for three months by an Appellate Division, First Department panel that considered several mitigating factors—including that McCoobery had no prior disciplinary history and that his father had been diagnosed with terminal illness and later passed away—while arriving at a suspension-punishment that had been put before it by joint motion of the Attorney Grievance Committee and McCoobery.
