'Appeal' in the Bible

Then I thought, "I will appeal to this: the years of the right hand of the Most High."

For if I have done wrong, and have committed anything worthy of death, I don't refuse to die; but if none of those things is true that they accuse me of, no one can give me up to them. I appeal to Caesar!"

But when the Jews spoke against it, I was constrained to appeal to Caesar, not that I had anything about which to accuse my nation.
