judgment as conclusive

A judgment, in its nature, concludes the subject on which it is rendered, and pronounces the law of the case. The judgment of a court of record whose jurisdiction is final, is as conclusive on all the world as the judgment of this court would be. It is as conclusive on this court as it is on other courts. It puts an end to inquiry concerning the fact, by deciding it... An imprisonment under a judgment cannot be unlawful, unless that judgment be an absolute nullity; and it is not a nullity if the court has general jurisdiction of the subject, although it should be erroneous.
