TRIPOLI: Libya’s top court on Monday rejected the Islamist-led parliament’s appointment of a new prime minister in a contested vote, ending one power struggle as a renegade general’s offensive against Islamist militias in the east rages on.

The Supreme Constitutional Court declared Prime Minister Ahmed Maiteg’s appointment unconstitutional, but gave no further details or instructions. Islamists in parliament and Maiteg said they would abide by the decision, thus leaving interim Prime Minister Abdullah Al-Thinni in office.

Al-Thinni refused to give up his office after last month’s vote in parliament, which saw a walkout by secular lawmakers and Islamists secure votes from legislators that opponents said weren’t there. Maiteg, a businessman who owns a luxury hotel in the capital, Tripoli, entered the government’s headquarters last week backed by an Islamist militia.

Twelve lawmakers later brought the matter to Libya’s Supreme Constitutional Court to challenge the vote that named Maiteg as interim prime minister.

Saleh Al-Makhzoum, the second deputy of parliament, told journalists after the court decision that the body would comply with the decision for the sake of the “state of law.” Maiteg also said he would “be the first to submit to the court decision and respect the judiciary.”

“What happened today is that we have made important gains toward building a state of law and institutions that we all are seeking,” he told journalists.

Libya has sunk into chaos following the downfall and the killing of longtime dictator Muammar Qaddafi in the country’s 2011 civil war. Heavily armed militias, born out of the rebel groups that toppled Qaddafi, now are the main power in the country.

The ruling comes as renegade Gen. Khalifa Haftar wages an offensive against Islamist militias. Over the past weeks, forces allied with Haftar have bombed the camps of Islamist militias, which have attacked his forces, including an assassination attempt on Haftar that killed four people.

The general has warned he will detain Islamist lawmakers, accusing them of financing militias which he blames for much of Libya’s chaos. In turn, Islamist politicians and others have accused him of launching a “coup,” though many tired of the turmoil in Libya have backed him with mass rallies.
