Russell S. Adler, whose name was on the door at Rothstein Rosenfeldt Adler when the Fort Lauderdale law firm collapsed under the weight of a $1.2 billion Ponzi scheme, is losing his law license for 91 days.

Adler was sanctioned Thursday by the Florida Supreme Court for making misrepresentations to a cooperative apartment board in New York when money from Ponzi leader Scott Rothstein was used to purchase a unit in August 2009, months before the settlement financing fraud collapsed.
