Two law firms that claim they are entitled to as much as 13 percent of the nearly $90 million the city of New York has paid out to victims of the 2003 Staten Island Ferry disaster suffered a minor setback in Brooklyn federal court last week.

Barberi, which killed 11 people and injured at least 70.
