Who said: "I would agree with Saint Augustine that 'an unjust law is no law at all.''?

Martin Luther King, "Letter from a Birmingham Jail":

"You express a great deal of anxiety over our willingness to break laws. This is certainly a legitimate concern. Since we so diligently urge people to obey the Supreme Court's decision of 1954 outlawing segregation in the public schools, it is rather strange and paradoxical to find us consciously breaking laws. One may well ask 'How can you advocate breaking some laws and obeying others?' The answer is found in the fact that there are two types of laws: there are just and there are unjust laws. I would agree with Saint Augustine that 'An unjust law is no law at all.' . . . A just law is a man-made code that squares with the moral law or the law of God. An unjust law is a code that is out of harmony with the moral law. To put it in the terms of Saint Thomas Aquinas, an unjust law is a human law that is not rooted in eternal and natural law."
