It can be any or all of that.
"Lawful characters tell the truth, keep their word, respect authority, honor tradition, and judge those who fall short of their duties. Chaotic characters follow their consciences, resent being told what to do, favor new ideas over tradition, and do what they promise if they feel like it. “Law” implies honor, trustworthiness, obedience to authority, and reliability. On the downside, lawfulness can include closemindedness, reactionary adherence to tradition, judgmentalness, and a lack of adaptability. Those who consciously promote lawfulness say that only lawful behavior creates a society in which people can depend on each other and make the right decisions in full confidence that others will act as they should."
"A lawful neutral character acts as law, tradition, or a personal code directs her. Order and organization are paramount to her. She may believe in personal order and live by a code or standard, or she may believe in order for all and favor a strong, organized government. Ember, a monk who follows her discipline without being swayed either by the demands of those in need or by the temptations of evil, is lawful neutral."
I picked the lawful section and LN as LN is really just law. It can be any or all of the things listed.
