Justice is more important than sacrifice

Deuteronomy 16:18-17:13
To be a judges and officials shall judge the people fairy. Do not pervert justice or show partiality. Do not accept bribe, for bribe blinds the eyes of the wise and twists the words of the righteous.
Do not sacrifice to the Lord an ox or sheep that has any defect or flow in it, for it would be detestable.
If you heard someone in your town worshiped other gods, then you must investigate it thoroughly. If it is true and it has been proved that this detestable things has been done in Israel, take those who has done this evil deed, and stone that person to dead. On the testimony of two or three witnesses a man shall be put to death, but no one shall be put to death on the testimony of only one witness.
If cases come before your courts that are to difficult for you to judge. Go to the priests, who are Levites, an the judge who is o office at that time. You must act according to the decisions they give you at the place the law they teach you and the decisions they give you. Do not turn aside from what they tell you to the right or to the left.
Why?
The Lord is righteous God, so his people shall to be doing justice. Here the Lord taught us how to do a judge with righteousness and remind us what we must obey it.
Summary: Do not accept bribe, justice publicly, investigate it thoroughly and act according to the decision they give you at the place the law they teach you. Do not turn aside from what they tell you.
If the judgement is justice then the people will hear and be afraid and will not be contemptuous again.
How?
Don't judge anyone, if I need to do judgment to define who is right I have to investigate it carefully. Follow the commands of the Lord and ask the Lord give me the wisdom to do it.
Justice deed is more important than sacrifice.
