Ellison denies Moti investigation politically motivated

Justice Minister Chris Ellison has rejected suggestions Australia's investigation of allegations of child sex offences against the Solomon Islands' Attorney-General is politically motivated.

The Solomons' Prime Minister has questioned Australia's motivation in trying to extradite Julian Moti from Papua New Guinea, describing the action as a serious violation of sovereignty.

In a statement, Senator Ellison says any allegation the investigation is politically motivated is baseless and the investigation began before the Solomons' elections in April.

Senator Ellison says Australia has followed proper procedures in its extradition request.

Mr Moti, an Australian citizen, is hiding in the Solomons High Commission in Port Moresby as the Federal Government continues to push for him to face court in Australia in relation to alleged child sex offences in Vanuatu.

Foreign Affairs Minister Alexander Downer is urging the Solomons to ensure Mr Moti is handed over to authorities.

"For as long as Mr Moti is in the Solomon Islands High Commission he is protected by diplomatic privilege, that is, police can't go and storm embassies or high commissions under the Vienna Convention," he said.

"So the Papuan New Guineans will have to wait until he leaves."
