A more thorough explanation: The ab-initio rule is a legal principle that refers to a decision or action being considered null and void from the beginning. This means that the decision or action is treated as if it never existed, and all consequences or effects of that decision or action are disregarded.
Example: The court applied the ab-initio rule, declaring the contract null and void from the beginning due to the parties’ lack of capacity to enter into a legal agreement.
