"Basically an amendment of a writ or party's pleading is allowed if such an amendment can prevent injustice. Conversely, any amendment which will result in injustice to the other party or which will violate the rule of audi alteram partem ought not be allowed. The rule will be infringed if an amendment is introduced at such a stage that the other side no longer has the opportunity of adducing its own answer to the point which the amendment has enabled the applicant to introduce."
