2 cited instruments linked from this judgment.
The Court refused to stop the plan-amendment process while Mount Barker Properties pursued an appeal. The appeal raised arguable issues, but the Court was not convinced that letting the process continue would make the appeal ineffective. It also considered the applicant's delay and the public and third-party interests affected by stopping the process. The Court did not decide whether the amendment was valid, whether the appeal would succeed, or what would happen to any later planning application.

Mount Barker Properties Pty Ltd challenged steps taken in connection with a proposal by the District Council of Mount Barker to amend its Development Plan. The immediate application before Doyle CJ was not the final appeal about the validity of the process. It was an interlocutory application seeking to stop the process continuing until that appeal could be heard.
The judgment records that the plaintiff first sought an injunction on 3 April to prevent a Council public meeting at which people who had made representations about the Plan Amendment Report (PAR) were to be heard. Lander J dismissed that application, considering that the meeting could proceed without depriving the plaintiff of the relief it sought in the action ([2]). On 4 April, the plaintiff commenced the action seeking declarations that the Council had not followed the procedures in s 25 of the Development Act 1993, and an injunction restraining further steps under that section ([3]).
The plaintiff later added the Minister as a defendant and challenged the Minister's acceptance of the draft PAR under s 25(9). Debelle J dismissed the application on 27 July. The plaintiff appealed on 9 August ([3]–[4]). By the time of Doyle CJ's decision on 10 October, the Minister had approved the PAR and was apparently about to have the amendment gazetted. The judgment notes that the declaration making an amendment authorised would be made by the Governor, not the Minister ([1]).
The plaintiff's new application sought to preserve the status quo until the appeal. It argued, among other things, that further steps could make the appeal nugatory, that issues about the amendment's validity might cease to be justiciable, and that a shopping-centre application might be assessed under the amended Plan before the appeal was resolved ([5], [12]–[14]).
Doyle CJ refused the injunction. That decision did not determine whether the Council had complied with s 25, whether the PAR was valid, or whether the appeal should succeed. The judgment dealt with interim relief only.
The Court accepted that the appeal raised an arguable point, but emphasised that it was not expressing a strong view about its prospects. Having read Debelle J's reasons, Doyle CJ said the point was arguable, but no more than that ([8], [16]). This was a provisional assessment made for the injunction application, not a final ruling on the underlying statutory challenge.
The question whether the appeal would be rendered nugatory was central. Doyle CJ drew an analogy with a stay of execution application and noted the usual rule that there is no stay, while also acknowledging that more recent decisions suggested the test was less stringent than the older exceptional-circumstances formulation ([9]). The Court was not satisfied that refusal of an injunction would make the appeal ineffective. It considered it arguable that the plaintiff could continue with the appeal even after gazettal and, if successful, obtain consequential relief, potentially including quashing the amendment ([10]).
That was deliberately a limited finding. Doyle CJ said he was not deciding that the appeal would not be rendered nugatory; he was deciding only that he was not satisfied that it would be ([10]). That distinction matters. The judgment did not settle what relief would be available after gazettal, nor the consequences of any later decision that the amendment was invalid.
The plaintiff relied on Happy Valley Shopping Centre v District Council of Meadows (1981) 27 SASR 117 in arguing that approval would make the validity question non-justiciable. Doyle CJ noted significant differences between the legislation considered in Happy Valley and the current Development Act. He considered the reasons given by Debelle J to strongly suggest that the process was justiciable, and was not satisfied that approval and gazettal would change that position ([12]). The Minister also undertook through counsel not to argue that the issues had ceased to be justiciable if the Plan was amended. The Council gave no similar assurance ([12]). The Court treated the plaintiff's argument as arguable, but did not accept that it justified an injunction on the material before it.
Other factors weighed against restraining the process. The plaintiff had not prosecuted the appeal as promptly as would have been desirable. Doyle CJ considered that the delay contributed to the situation, though he expressly said it was not decisive ([6]–[7], [16]). The plan-amendment process affected residents and businesses in the Council area, and the Court considered there was a broad public interest in its proceeding with reasonable expedition ([7], [11]). An injunction would halt that process and could affect people whose interests and circumstances the Court could not assess on the application ([11], [16]).
The potential shopping-centre application did not alter the result. Doyle CJ acknowledged that it was arguable that a later application might be dealt with by reference to the Plan as amended, even if the amendment were subsequently held invalid. But the Court did not decide that issue. It noted that the plaintiff might be able to seek an injunction if such an application were made, and that an undertaking as to damages would almost certainly be required if that injunction were granted ([13]–[15]). These were observations about a possible future application, not a ruling on its availability or merits.
The conclusion was therefore cumulative and interim. The appeal was arguable, but the Court was not satisfied that the appeal would be rendered nugatory. The plaintiff's delay, the public interest in the statutory process, and the potential impact on others also counted against relief. Doyle CJ was not persuaded that the interests of justice or balance of convenience favoured stopping the process ([16]).
The judgment does not purport to establish a comprehensive new test for interlocutory injunctions pending appeal. Doyle CJ described the application as similar to a stay of execution application. He referred to the traditional position that there is no stay, while noting that more recent decisions suggested the test was not as stringent as a requirement to establish exceptional circumstances ([9]). The judgment does not identify those more recent decisions, so no further account of their content can safely be given from this text.
The decision's central contribution in this particular dispute was its application of the nugatory-appeal question alongside public-interest and balance-of-convenience considerations. It asked whether continuation of the statutory process would leave the appeal practically pointless, and considered the possibility of consequential relief after gazettal ([10]–[12]). The Court's answer was cautious: it was not satisfied that the appeal would be rendered nugatory, rather than conclusively holding that it could not be.
The judgment also considered whether the statutory process would become non-justiciable after approval and gazettal. It did not declare that the issues would remain justiciable in all circumstances. Rather, it regarded the applicant's argument as arguable but was not persuaded that it was sound, having regard to the differences between the Development Act and the legislation considered in Happy Valley, and Debelle J's reasons ([12]).
The material supplied contains no later decisions applying, distinguishing, or otherwise treating this judgment. Accordingly, the later state of the law cannot be established from this judgment text alone. The judgment's own holding should be understood as a fact-specific interlocutory ruling, not as a final decision on the statutory validity issues or the consequences of an invalid amendment.
At [9], Doyle CJ said that the application was “rather like an application for a stay of execution on a judgment” and referred to the usual rule that there is no stay. In plain English, he treated the request as one requiring the Court to consider whether an existing or impending process should be paused while an appeal is pending. He also recognised that the relevant threshold was not necessarily the strict exceptional-circumstances test associated with older decisions.
At [10], Doyle CJ stated: “I am not satisfied that the refusal to order a stay would render the appeal nugatory.” He immediately qualified this, explaining that he was not deciding that the appeal would not be rendered nugatory. The plain-English point is that the applicant had not persuaded the Court, at this interim stage, that allowing the process to continue would destroy the practical value of its appeal.
Also at [10], the Court considered it “quite arguable” that the plaintiff could pursue the appeal after gazettal and, if successful, obtain further consequential relief, potentially quashing the amendment. This did not guarantee that such relief would be available. It explained why the Court was not satisfied that the appeal would become pointless.
At [12], Doyle CJ acknowledged that the justiciability argument was arguable, but said he was “by no means satisfied that the point is sound.” In plain English, the Court recognised a possible legal issue about the effect of approval and gazettal, but did not accept that the issue justified stopping the process at that time. The paragraph also records that the Minister gave an assurance about not disputing justiciability, while the Council gave no such assurance.
At [14], the Court said that it was not right to treat the plaintiff's commercial interests in delay as decisive. The decision therefore considered more than the parties' immediate commercial positions. It also referred to people who might be advantaged or disadvantaged by making or delaying the amendment.
At [16], Doyle CJ summarised the balancing exercise. The appeal raised an arguable point, but the Court was not satisfied the amendment's gazettal would make the appeal nugatory. The plaintiff had been slow to progress the appeal, and there was a public interest in allowing the statutory process to continue. The application was refused because the Court was not satisfied there was good reason to interfere.
This judgment is most directly relevant to an application for interim relief seeking to halt a statutory planning process while a related appeal is pending. Its reasoning is tied to the circumstances recorded in the judgment: the proposed plan amendment had reached an advanced stage; the applicant argued that later steps would undermine the appeal; the appeal raised an arguable point; and the process affected people beyond the parties ([1], [5]–[8], [16]).
The case may be informative where the court is asked whether allowing an administrative or statutory process to continue would make an appeal nugatory. The judgment shows that the court considered whether the applicant could still pursue the appeal and seek consequential relief after the challenged step occurred ([10]). It does not establish that post-event relief will always be available, or that continuation of a process will never make an appeal nugatory.
The decision also illustrates that delay in progressing an appeal may count against interim relief. Here, almost nine weeks had passed without the appeal being set down, and Doyle CJ considered that it might have been heard sooner if pursued more promptly ([6]). The delay was a factor, not a complete answer ([7]).
The public and third-party effects of an injunction were also relevant. The Court noted that a plan amendment could affect residents and businesses, and that it could not assess the interests of all potentially affected people on the application before it ([7], [11], [16]). The judgment therefore has particular relevance where an injunction would suspend a process with broader community effects.
The decision does not itself resolve an application concerning a different statute, a different stage of administrative decision-making, or a different kind of prejudice. Doyle CJ expressly noted that Happy Valley involved materially different legislative provisions ([12]). Any use of the judgment in another setting would need to account for the governing statutory scheme and the precise relief sought.
The judgment supplied for this analysis contains no later judicial decisions citing or discussing Doyle CJ's ruling. It is therefore not possible, on this source alone, to say whether later courts have followed, applied, distinguished, or limited it.
The only precedent expressly discussed in the judgment is Happy Valley Shopping Centre v District Council of Meadows (1981) 27 SASR 117. The applicant invoked that authority in support of the argument that further steps would make the validity issues non-justiciable. Doyle CJ identified significant differences between the statutory provisions in Happy Valley and those in the current Development Act, and was not persuaded that the argument justified an injunction ([12]). The judgment thus treated Happy Valley as distinguishable in the context of the applicant's submission.
No later treatment should be inferred from the judgment's publication date, its “Last Updated” metadata, or the fact that it cites Happy Valley. Establishing the subsequent history would require sources beyond the judgment text provided here.
Several questions were left undecided. First, the Court did not determine the merits of the appeal from Debelle J's decision. It characterised the appeal as arguable but did not make a final finding about whether the Council or Minister had complied with s 25 of the Development Act ([8], [16]).
Second, the Court did not finally decide whether gazettal would render the appeal nugatory. It was not satisfied that it would, while expressly avoiding a conclusive finding that it would not ([10]). Whether consequential relief could actually be granted after the amendment was made remained for determination in the appropriate proceedings.
Third, the Court did not conclusively decide whether the validity issues would remain justiciable after approval and gazettal. It considered the argument arguable but not persuasive on the interlocutory application, and noted the Minister's assurance and the Council's lack of a corresponding assurance ([12]).
Fourth, the Court did not decide how a future planning application for a shopping centre would be assessed if made under the amended Plan before resolution of the appeal, or what the effect would be if the amendment were later held invalid ([13]–[14]). Nor did it determine whether a later injunction could be obtained. The observation about an undertaking as to damages was conditional on such an injunction being granted ([15]).
Finally, the judgment does not state how later courts treated its reasoning. The supplied source supports analysis of Doyle CJ's decision and its treatment of Happy Valley, but not a broader account of subsequent precedent.

The application is rather like an application for a stay of execution on a judgment and the usual rule is that there is no stay. Earlier cases suggested that to get a stay you must demonstrate exceptional circumstances but more recent decisions suggest the test is not so stringent. In any event, it is relevant to consider whether the refusal to grant a stay would render the appeal nugatory. In this case an important issue is where the refusal to order a stay would render the appeal nugatory.
I am not satisfied that it would, which is not to say I am deciding now that it would not, I am merely holding that I am not satisfied that the refusal to order a stay would render the appeal nugatory. Even if the Minister proceeds to gazette the amendment, it seems to me quite arguable that the plaintiff is at liberty to proceed with the appeal and, if successful, obtain the relief it seeks, subject only to the Full Court granting further consequential relief and quashing the amendment to the Plan, assuming it has been made by then.
So while I accept that there is an arguable point raised by Mr Hayes, I am not satisfied that the refusal of the order will render the appeal nugatory. By contrast, if I grant an injunction the process will come to a halt pending the hearing and determination of the appeal, and that affects the public interest. But, once again, I have to acknowledge that the delay there should not be lengthy.
Mr Hayes also argued if the PAR is approved, the question of whether it has been validly made will not be justiciable, referring to the decision of the Full Court in Happy Valley Shopping Centre v District Council of Meadows (1981) 27 SASR 117. However, there are significant differences between the provisions of the current Development Act and the legislation under consideration there. The reasons given by Debelle J strongly suggest that the process of dealing with the PAR is justiciable, and this would not be affected by a decision by the Minister to approve the amendment and then gazette the amendment. I gather it was not argued before Debelle J by any party that the issues before him were not justiciable. Again, I acknowledge Mr Hayes' point which seems to be that the decision by the Minister to approve the amendment and then the decision by the Governor to gazette the amendment changes things but, once again, while I accept there is an arguable point there, I am by no means satisfied that the point is sound. I note that the Minister has assured the court through counsel that she will not argue that the points are no longer justiciable if the Plan has been amended, but I note also that the Council was not prepared to give any such assurance.
The plaintiff is also concerned that if the amendment to the Plan is gazetted, an application may be made for planning approval for a shopping centre in Mount Barker, relying on the amendment to the Development Plan. The plaintiff fears that even if later the amendment is held invalid, the application will be dealt with on the basis of the Plan as amended being the law in force when the application was made, assuming the application is made before a decision allowing the appeal, and once again, assuming the ultimate decision is to allow the appeal.
Whether the application would be dealt with by reference to an invalid amendment is something that, again, I should not decide now. The point is arguable, I suppose. But a range of people may be interested in and advantaged or disadvantaged by the amendment being made now or being delayed. I do not think that it is right that the plaintiff's commercial interests in delay should be treated as decisive. Moreover, it may yet be open to the plaintiff to seek an injunction to restrain the planning authority and the applicant in question from dealing with the application, if it is made. Again, I should not decide if such an application can be made or would succeed. I merely note the possibility.
In that event, the plaintiff, I think, would almost certainly have to give an undertaking as to damages if it were to obtain an injunction. I consider that would be the appropriate way for the plaintiff to deal with this issue.
In summary, the appeal raises an arguable point but not one that can be said to have strong prospects of success on the basis of my reading of Debelle J's reasons. I am not satisfied that the gazettal of the amendment to the Plan will render the appeal nugatory, but I acknowledge it is arguable that may occur. The plaintiff has been slow in progressing its appeal contributing to the situation that it now faces. I am not persuaded that the interests of justice, or even the balance of convenience, favour preventing the Minister from dealing with the proposed amendment, bearing in mind that such an order could have effects on a range of people whom I cannot identify and effects I am unable to assess. There is a contrary general public interest in allowing the statutory process to continue. To my mind the court should only interfere in such a case if there is good reason to do so, and I am not satisfied in this case that there is and, accordingly, I refuse the application.
