The correct answer is (a) Stay of suit.
Res judicata is a Latin phrase that means “a matter adjudged.” It is a legal principle that states that a final judgment on the merits of a case by a court of competent jurisdiction is conclusive of the rights of the parties, and prevents them from relitigating the same issues in a subsequent action.
The doctrine of res judicata is based on the principle of finality, which holds that once a court has rendered a final judgment, the parties should be able to rely on that judgment and not have to worry about the possibility of the case being relitigated. The doctrine also serves to promote judicial efficiency by preventing courts from having to hear the same case multiple times.
There are a number of exceptions to the doctrine of res judicata, such as when there was fraud or mistake in the original proceeding, when there has been a change in the law, or when the party seeking to relitigate the case was not a party to the original proceeding.
In the context of the question, the term “res sub judice” means that the matter is currently being litigated in court. This means that the parties to the case are prohibited from taking any action that would prejudice the outcome of the case, such as filing a new lawsuit or taking any steps to enforce a judgment.
The other options are incorrect because they do not accurately reflect the meaning of the term “res sub judice.” Option (b), “Stay of appeal,” refers to a court’s order that temporarily prevents a party from appealing a judgment. Option (c), “Stay of application,” refers to a court’s order that temporarily prevents a party from taking any action on an application. Option (d), “Stay of execution,” refers to a court’s order that temporarily prevents a party from enforcing a judgment.
