• Unlike an amended pleading, a supplemental pleading merely adds to the earlier pleading and does not replace it. Cf. amended pleading. [Cases: Federal Civil Procedure 861–871; Pleading 273. C.J.S. Pleading §§ 456–460.]
supplemental pleading
A pleading that either corrects a defect in an earlier pleading or addresses facts arising since the earlier pleading was filed.
