Within the Holy Roman Empire, the privilegium de non appellando (privilege of not appealing) was a privilege that could be granted by the emperor to an imperial estate.
[1] The privilege itself could be limited (limitatum) or unlimited (illimitatum).
[1] The privilege was highly prized by imperial estates, both because it lent prestige and because it furthered the integration of their administration by cutting off their judiciary from the rest of the Empire.
Between the 16th and 18th century, virtually all the larger estates received the privilege.
It did not apply when a subject was given no recourse to territorial courts (refusal of justice, Rechtsverweigerung) or when a ruler refused to implement a court decision (delay of justice, Rechtsverzögerung).
