The speaker of the assembly James Wani Igga said the bill represents the second remarkable achievement by the assembly after the interim constitution.
He added that the bill will curb mounting corruption in southern Sudan.
The chairperson of the Anti-Corruption Commission Pauline Riak said in a press statement that the commission is to investigate and compile corruption cases and refer them to the prosecutor.
Answering a question from Miraya FM on whether the commission will look into earlier cases of alleged corruption in Southern Sudan before the bill was endorsed, Mrs. Pauline Riak ruled out any time limitations.
The report of the committee of the public account and legal affairs on the Anti-Corruption Commission bill was presented to the house by the chairperson of the Public Account Committee Dr Jimmy Wango.
The bill becomes a law when the President of the government of Southern Sudan signs it.
