“ What the Constitution and the congressional enactment require is that a judgment of a court of one state, if founded upon adequate jurisdiction of the parties and subject matter, shall be given the same faith and credit in a court of another state that it has by law or usage in the courts of the state of its rendition. ”

“ Our jurisdiction is challenged by a motion to dismiss.
There are three assignments of error, and the facts essential to an understanding of two of them are these: After the judgment of interdiction, and before the hearing upon the appeal, the plaintiff in error, who was in custody under an order of the criminal district court of the parish, committing him to an asylum as a dangerous insane person, secured his release from such custody through an original proceeding in habeas corpus in the court of appeal of the parish, which adjudged that he had recovered his sanity. ”

“ This presupposes that the law or usage in the latter state will be brought to the attention of the court in the other state by appropriate allegation and proof, or in some other recognized mode; for the courts of one state are not presumed to know, and therefore not bound to take judicial notice of, the laws or usage of another state. ”
