Noun

1.

last resort - French for `worst going' Synonyms: pis aller

LAST RESORT. A court of last resort, is one which decides, definitely, without appeal or writ of error, or any other examination whatever, a suit or action, or some other matter, which has been submitted to its judgment, and over which it has jurisdiction.
     2. The supreme court is a court of last resort in all matters which legally come before it; and whenever a court possesses the power to decide without appeal or other examination whatever, a subject matter submitted to it, it is a court of last resort; but this is not to be understood as preventing an examination into its jurisdiction, or excess of authority, for then the judgment of a superior does not try and decide so much whether the point decided has been so done according to law, as to try the authority of the inferior court.

expedient, pis aller
