“5. It is true that, if a plaintiff seeks to alter the cause of action itself and to introduce indirectly, through an amendment of his pleadings, an entirely new or inconsistent cause of action, amounting virtually to the substitution of a new plaint or a new cause of action in place of what was originally there, the Court will refuse to permit it if it amounts to depriving the party against which a suit is pending of any right which may have accrued in its favour due to lapse of time. But, mere failure to set out even an essential fact does not, by itself, constitute a new cause of action. A cause of action is constituted by the whole bundle of essential facts which the plaintiff must prove before he can succeed in his suit. It must be antecedent to the institution of the suit. If any essential fact is lacking from averments in the plaint the cause of action will be defective. In that case, an attempt to supply the omission has been and could sometimes be viewed as equivalent to an introduction of a new cause of action which, cured of its shortcomings, has really become a good cause of action. This, however, is not the only possible interpretation to be put on every defective state of pleadings. Defective pleadings are generally curable if the cause of action sought to be brought out was not ab initio completely absent. Even very defective pleadings may be permitted to be cured, so as to constitute a cause of action where there was none, provided necessary conditions such as payment of either any additional Court fees, which may be payable, or, of costs of the other side are complied with. It is only if lapse of time has barred the remedy on a newly constituted cause of action that the Courts should, ordinarily, refuse prayers for amendment of pleadings.”
