A lawyer has demanded Attorney-General Idrus Harun clear the air surrounding the questions raised over the US$14.92 billion (RM62.6 billion) "final award" by a Spanish arbitrator to the Sulu Sultanate's purported descendants.

In a statement today, Mohamed Haniff Khatri Abdulla said Idrus should respond to the lawyers representing the Sulu claimants who had refuted his statement issued on Feb 28.
