In countries where the 'rule of law' applies, there is usually a dislike of legislation which has retrospective effect. In this brief post, I do not seek to discuss in any detail the merits or otherwise of the arguments for or against retrospective legislation, save to say that with regard to legal certainty, it is important both for individual citizens and business enterprises as well as other legal entities that they can assess the legality and legal effects of a planned action before instituting such action.

Juristic act refers to an action intended to, and capable of having, a legal effect. It includes creation, termination, or modification of a legal right. A court executes a juristic act when it makes a decision and hands down a judgment. An individual entering into contractual agreement is also performing a juristic act because of the legal complexities of the agreement. (USLegal)

The second doctrine of res judicata, that the finding of the court as to facts and rights shall, under certain circumstances, be conclusive if the same matters come into issue in a later action upon a different cause, is not, as is the first doctrine, a necessary consequence of the legal effect of the prior judgment.
