New York's top court has upheld Gov. David Paterson's power to appoint a lieutenant governor, reversing a lower court's decision.

The court ruling released Tuesday is a timely victory for Paterson, who is facing calls from national Democratic Party leaders to abandon his bid for governor in 2010.

The ruling makes Richard Ravitch the state's lietenant governor. Paterson appointed him July 8 to help break a monthlong Senate leadership struggle,

Senate Republican leader Dean Skelos then filed a lawsuit challenging Paterson's authority to make the appointment.

The lieutenant governor's post had been empty since Paterson stepped up to replace Eliot Spitzer, who resigned last year amid a prostitution scandal.
