'Appealed' in the Bible

Then, after conferring with the Council, Festus replied, "To Caesar you have appealed: to Caesar you shall go."

But when Paul appealed to have his case kept for the Emperor's decision, I ordered him to be kept in prison until I could send him up to Caesar."

I could not discover that he had done anything for which he deserved to die; but as he has himself appealed to the Emperor, I have decided to send him to Rome.

And Agrippa said to Festus, "He might have been set at liberty, if he had not appealed to Caesar."
