retrospective: expr. by the advs. retro, retrorsus (-um): if we wish to make it a r. enactment much confusion must arise, cujus (legis) vim si retro velimus custodire multa necesse est perturbari, Trajan in Plin. Ep. 10, 116: lest it should be made r., ne cujusquam retro habeatur ratio, Plin. Ep. 10, 119: because the action is r., quia retrorsum se actio refert, Ulp. Dig. 13, 5, 10, § 1.
