(a) the essential functions of a pleading are to define and limit the issues for decision, to provide the basis for determining discovery and the admissibility of evidence for trial, and to ensure a fair trial by putting the other side on notice of the case it must meet;
(b) a statement of claim must not plead allegations at too high a level of generality. A pleading must be sufficiently particular to conform with one of the primary objects of pleadings, to inform the opposing party of the case that it must meet;
(c) a statement of claim must state specifically the relief or remedy claimed;
(d) the court should proceed with caution before striking out a pleading on the ground that it does not disclose a reasonable cause of action. While the court may determine a difficult question of law on such an application, it would usually be appropriate to leave the determination of such questions for trial;
(e) in alleging no reasonable cause of action:
(i) the question to be decided is not whether the facts pleaded are in themselves sufficient to give rise to a cause of action. Rather, the question is whether it would be open to the party (on its pleadings) to prove facts at the trial which would constitute a cause of action; and
(ii) 'reasonable' means reasonable according to law. If the facts pleaded conceivably give rise to relief, then the cause of action should be held to be reasonable;
(f) the mere fact that a case appears weak is not of itself sufficient to strike out the action;
(g) in considering a strike out application, it is now necessary to consider the role of pleadings in the context of case management techniques. Case management considerations are not, however, necessarily antithetical to the observance of pleading rules. The objects of O 1 r 4A and 4B of the Rules of the Supreme Court 1971 (WA) are often promoted by a clear and precise statement of the issues for decision;
(h) provided a pleading fulfils its basic functions of identifying the issues, disclosing an arguable cause of action (or defence), and apprising the parties of the case that has to be met, the court ought properly be reluctant to allow the time and resources of the parties and the limited resources of the court to be spent extensively debating the application of technical pleading rules that evolved in, and derive from, a very different case management environment;
(i) pleadings may be struck out on the ground that they may prejudice, embarrass or delay the fair trial of the action because they are evasive, they conceal or obscure the real questions in controversy, they are ambiguous or not reasonably intelligible, they raise immaterial or irrelevant issues, they fail to confine the issues or state the case of the party in question with reasonable particularity, or they raise a case in terms which are simply too general; and
(j) irrelevant or unnecessary pleas in a statement of claim will be struck out on the grounds that they will prejudice, embarrass or delay the fair trial of the action where the defendant must traverse the allegations and, thereby, raise false issues.
