Illustrate the exceptions to the general rule of pleadings that pleading must state material facts only.

The second fundamental rule of pleading, namely, that every pleading must state all the material facts and the material facts only is subject to the following well known exceptions: Condition Precedent: The performance of occurrence of any condition precedent need not be pleaded as its averments shall be implied in the pleading. But where a party chooses to contest the performance or occurrence of such condition, he is bound to set-up the plea distinctly in his pleading. This follows from the provision contained in Order VI Rule 6 C.P.C. which runs thus: "Any condition Precedent, the performance or occurrence of which is intended to be contested, shall be distinctly specified in his pleading by the plaintiff or defendant, as the case may be; and, subject thereto, an averment of the performance or occurrence of all conditions precedent necessary for the case of the plaintiff or defendant shall be implied in his pleading." Presumption of Law: Order VI Rule 13, C.P.C., provides that neither party need in any pleading allege any matter of fact which the law presumes in his favour or as to which the burden of proof lies upon the other side unless the same has first been specifically denied. For example in a suit on a promissory note the plaintiff need not allege consideration as Section 118 of Negotiable Instruments Act, 1881 raises a presumption in his favour. It is also not necessary to state that the defendant executed the bond of his own free will and without any force or fraud because the burden of proving any fact invalidating the bond lies upon the defendant. Matters of Inducement: Another exception to the general rule is regarding facts which are merely introductory. Such facts only state the names of the parties, their relationships, their professions and such circumstances as are necessary to inform the court as to how the dispute has arisen. Such facts are hardly necessary or material to the pleading, but they are generally tolerated and are set in the pleadings by both the parties in order to facilitate the court to take a stock of the situation of the parties. It is better if such prefatory remarks are cut down to the minimum.
