Washington ? High court nominee Sonia Sotomayor typically handed out tougher prison sentences than her colleagues in the federal courthouse in Manhattan, especially to white-collar criminals, a new study says.

Nearly half the people Sotomayor sentenced for financial fraud and other white-collar crimes received at least 6 months in prison, according to an analysis released Thursday by the Transactional Records Access Clearinghouse at Syracuse University.

By contrast, roughly one out of three white-collar convicts received similarly lengthy prison terms from the other trial judges in the Southern District of New York, the study found.

Sotomayor served as a trial judge from 1992 to 1998.
