A Manhattan federal judge has thrown out a legal malpractice suit arising out of competing Holocaust restitution claims.

In 2005, a group of nieces and nephews of Jewish publisher and art collector Gustav Kirstein and his wife Clara, both of whom died in Germany in the 1930s, sued their former lawyer, New York’s David J. Rowland, claiming his mistakes caused them to have to share restored property and funds with another claimant.
