The Attorney General of Sri Lanka is the Sri Lankan government's chief legal advisor, and its primary lawyer in the Supreme Court of Sri Lanka. The Attorney General is usually a highly-respected Senior Advocate, and is appointed by the ruling government. The current Attorney General is Mohan Peiris, PC. The president does not have any power to make orders, mandatory or otherwise, to the attorney general. He heads the Attorney-General's Department.
Unlike the Attorney General of the United States, the Attorney General of Sri Lanka does not have any executive authority, and is not a political appointee; those functions are performed by the Minister of Justice. The Attorney General is assisted by the Solicitor General of Sri Lanka and several Additional Solicitors General.
