The Arab League is backing Libya's intention to try a son of deposed ruler Moammar Gadhafi at home instead of turning him over to the International Criminal Court.
The ICC has insisted that Libya hand over Seif al-Islam Gadhafi for trial on charges of murdering civilians during the uprising that toppled his father's regime last year.
The Arab League said in a statement Monday that it supports Libya's right to try him.
Seif al-Islam, considered his father's heir-apparent, was captured last year. He is being held in the western town of Zintan.
The court dismissed Libya's latest appeal, but the ICC cannot force Libya to comply with its order to turn him over.
There is concern that Libya's judicial system may not be ready to give him a fair trial.
