The current case flow management regime now applicable to civil actions was explained by the Chief Justice in Areva NC (Australia) Pty Ltd v Summit Resources (Australia) Pty Ltd [No 3] [2009] WASC 67. In addressing redaction issues arising around certain documents produced on discovery, the Chief Justice noted the introduction of O 1 r 4A and r 4B and the significance of those rules towards the resolution of discovery issues. Although I am dealing with inspection objection issues over documents produced on subpoena, similar considerations guide the task of trying to keep the breadth of documents turned over in preparation for a trial within manageable bounds. It should be remembered that there has been a recent liberalisation of the procedures under which a party in civil litigation may have a subpoena returnable and answered before trial. A former requirement for leave to be obtained for an early return before trial of a document subpoena has been removed: see O 36B r 3(6) and Consolidated Practice Direction [4.3.7] pars 4, 5 and 14 and Areva NC (Australia) Pty Ltd v Summit Resources (Australia) Pty Ltd [2007] WASC 276. So the principles applicable to case flow management have intensified since the Full Court decided Apache Northwest.
Nevertheless, what is now a relatively unconstrained right for a party to issue a document subpoena returnable before trial is potentially capable of producing forays into fields of documentary irrelevance. This carries with it considerations of expense for the litigation. There is in consequence now scope to compound an already existing problem with a seemingly uncontrollable cost and parameters of the pre-trial discovery processes that threatens to render the cost of civil litigation prohibitive for all but the wealthiest of litigants.
Accordingly, a firm curial oversight must be kept upon these compulsive pre-trial documentary processes, lest they become abused or unduly oppressive in their ramifications for parties to litigation [35] [37].
