32. Order 83 Rule 1 of the Rules provides that:
Whenever any issues between the same parties can be conveniently tried together, or whenever it appears desirable notwithstanding that the parties are not identical and that the evidence necessary to prove the issues is not identical, the Court may consolidate any number of causes or matters in order to quiet all claims relating to one subject matter, transaction or event, or to substantially similar subject matters, transactions or events.
33. In Lois Nominees Pty Ltd v QBE Insurance (Aust) Ltd [2011] WASC 208; (2011) 42 WAR 75 [77] - [81], Beech J listed the factors to be considered when determining whether to make orders for consolidation pursuant to Order 83 of the Rules. These are as follows:
(a) There is no presumption against consolidation.
(b) Each case depends on its own facts and circumstances.
(c) The rule is to be construed as a flexible rule of convenience in the administration of justice, suggesting that the court has the power to do what is necessary and appropriate to permit effective consolidation with a view to final determination of the real issues between the parties, with justice to all concerned.
(d) Broadly, the question on a consolidation application is whether in all the circumstances it is convenient, having regard to avoiding multiplicity of actions and to saving time and expense.
(e) Among the matters that may be relevant to the exercise of discretion regarding consolidation are:
(i) whether it is convenient to consolidate the actions, including whether it will prevent multiplicity of actions and ensure savings of time and cost;
(ii) whether there are common questions of law or fact or a common transaction or series of transactions;
(iii) whether consolidation will cause prejudice or unfairness to any parties;
(iv) whether consolidation will be conducive to a just resolution of the issues; and
(v) whether there are any practical matters which may make it inexpedient to consolidate.
34. Further, the Court of Appeal in Sino Iron Pty Ltd v Mineralogy Pty Ltd [2019] WASCA 80; (2019) 55 WAR 89 [408] approved the observations made by Beech J at [77] - [81], and went on at [410] to add that the application of Order 83 is to be construed and applied by regard to Order 1 Rule 4B of the Rules. This requires that Order 83 "must be construed and applied so as 'best to ensure the attainment' of (amongst other things) (1) promoting the just determination of litigation, (2) disposing efficiently of the court's business, (3) maximising the efficient use of available judicial and administrative resources, and (4) facilitating the timely disposal of business."
