Final means pertaining to or coming at the end, conclusive or decisive. In law, final means:
Precluding further controversy on the questions passed upon. For example, the judgment of the Supreme Court is final.
Determining all issues presented, so that no further decision upon the merits of the issues is necessary. For example, a final judgment or decree. Once an order, judgment, or decree is final, it may be appealed on the merits.
