Supplemental

Added to a thing to complete it; supplying a defect in something that precedes: as, a supplemental affidavit, bill, answer, complaint, petition, — each of which adds to or supplies matter either not previously known or omitted as non-essential, without taking the place of the original paper or proceeding. See Answer, 3; Bill, IV; Defense, 2, Affidavit 9f. "Supplementary" and "suppletory" are also used, as, of an oath to books of original evidence, and of comparison of handwriting, at common law. See Oath, Suppletory. As to supplemental legislation, see Title, 2, Of act.
