19 There are differing authorities in this court with respect to the test properly applied in order to determine whether or not an order nisi should be granted in proceedings such as these. The differing authorities have been recently and conveniently summarised in Re Her Honour Judge Schoombee; Ex Parte Attorney General for Western Australia [2011] WASC 23, [11] [18] and Seddon v Medical Assessment Panel [2011] WASC 237 [29] [32]. In short, some but not all of the authorities have suggested that there is a two-fold test which requires the court first to assess whether the applicant has an arguable case, and if so, whether the applicant has reasonable prospects of success (see, for example, my observations in Woodley v Minister for Indigenous Affairs [2009] WASC 251). Other (generally earlier) authorities suggest that there is a single test, which is whether an arguable case has been established, which has in some cases been described as a threshold test which is 'quite low' (see, for example, Re Capobianco; Ex Parte Castelli, Unreported, WASC, Library No 980567, 18 & 25 September 1998 (Parker J)).
