Step 1: Understanding the Doctrine of Res Judicata.
The doctrine of res judicata bars the re-litigation of a matter that has already been decided in a previous suit between the same parties. If a matter has been adjudicated upon and the judgment is final, a new suit on the same issue cannot be filed.
Step 2: Explanation of Other Options.
- (b) The suit is not liable to be stayed. If the matter is res judicata, it cannot be stayed.
- (c) Both (a) and (b) are incorrect as the suit is not stayed but dismissed.
- (d) None of the above is incorrect as the suit is dismissed under res judicata.
Step 3: Conclusion.
The suit is liable to be dismissed if the doctrine of res judicata applies.
