Hon'ble Supreme Court of India observed as “16. The object of the rule is that Courts should try the merits of the case that come before them and should, consequently, allow all amendments that may be necessary for determining the real question in controversy between the parties provided it does not cause injustice or prejudice to the other side.
17. Order VI, Rule 17 consist of two parts whereas the first part is discretionary (may) and leaves it to the Court to order amendment of pleading. The second part is imperative (shall) and enjoins the Court to allow all amendments which are necessary for the purpose of determining the real question in controversy between the parties.
19. As discussed above, the real controversy test is the basic or cardinal test and it is the primary duty of the Court to decide whether such an amendment is necessary to decide the real dispute between the parties. If it is, the amendment will be allowed; if it is not, the amendment will be refused.”
