'Decisions' in the Bible

Does God give wrong decisions? or is the Ruler of all not upright in his judging?

For the band of the evil-doers gives no fruit, and the tents of those who give wrong decisions for reward are burned with fire.

And you say, What knowledge has God? is he able to give decisions through the deep dark?

I put on righteousness as my clothing, and was full of it; right decisions were to me a robe and a head-dress.
