✓ 18. In the case of Barbieri vs Morris, Mo; 315 S.W. 2d 711 at page 714, it was said that retroactive laws are generally defined from a legal viewpoint as those which take away or impair vested rights acquired under existing laws, create new obligations, impose a new duty or attach a new disability in respect to the transactions ot considerations already past. In other words it is a law that is intended to act on things, which are past.
✓ 19. Another important definition is to be found in the case of Bear Val Mutual Water Co. vs. San Bernardino County, 242 Cal. App. 2d, 68, where it was stated that a retrospective law is one which looks backward or contemplates the past, one which is made to affect acts or facts occurring, or rights accruing, before it came into force. Every statute, which takes away or impairs vested rights acquired under existing laws, or creates a new obligation, imposes a new duty, or attaches a new disability in respect of transactions or considerations already past. One which relates back to a previous transaction and gives it a different legal effect from that which it had under the law when it occurred.
