A New York judge has declined to recuse himself from a case in which evidence spoliation allegations have been made against the law firm where his son works as an associate.

The recusal motion against Manhattan Supreme Court Justice Herman Cahn arose in a compensation dispute between two former hedge fund partners, in which the defendant is represented by Greenberg Traurig partner Leslie D. Corwin. The plaintiff has accused Corwin of helping his client cover up the destruction of a key document in the case.
