A Jamaican court has rejected a motion by police officers challenging the powers of an independent commission that investigates alleged abuses by security forces.

The Independent Commission of Investigations says the Supreme Court ruling Wednesday is a "major victory."

The policemen challenged charges brought against them for failing to cooperate with the commission as it investigated the fatal shooting of two men in August 2010.

The commission says the court's decision means it can compel police or any other person to give statements or answer questions as part of an abuse probe.

Earlier this year, police representatives called for commission chief Terrence Williams to resign after he appeared at a briefing with a human rights group amid an upsurge in slayings by Jamaican police.
