Honduras's Supreme Court has rejected a Costa Rica-brokered deal that would have restored ousted President Manuel Zelaya to power and sternly warned that he faces arrest if he returns.

In a ruling late Saturday that fell in line with similar pronouncements by the military-backed regime, the high court said that Zelaya will not be allowed to return to power, and "cannot avoid having to submit to established procedures of the penal process" should he return to Honduras.

Zelaya was ousted from power in a June 28 military-backed coup and replaced with interim leader Roberto Micheletti.

The court decision also accused Zelaya of "crimes against the government, treason against the nation, abuse of power" and other misdeeds, as it affirmed the legitimacy of Micheletti's government.

Micheletti's government had been installed as part of a lawful "constitutional succession," the high court found.
