Executive Summary: Key Legal and Evidentiary Issues

• Characterisation of the Anton Piller order and related ruling as interlocutory rather than final, and its consequences for appeal rights under The Court of Appeal Act, 2000.
• Scope of s. 8(2)(a)(iii) of The Court of Appeal Act, 2000, and whether an Anton Piller order and the refusal to vacate it qualify as an order involving the “granting or refusal of an injunction.”
• Distinction between extraordinary Anton Piller relief and ordinary procedural orders, including how courts apply an “injunction-type” analytical framework to this form of pre-trial search and seizure.
• Treatment of an order admitting an affidavit into evidence as an incidental interlocutory order, and when such an evidentiary ruling may be appealed together with the main interlocutory order.
• Interpretation of prior Saskatchewan authorities on final versus interlocutory orders, and on whether particular compelled acts (e.g., medical examinations) fall within the statutory category of “injunctions.”
• Effect of delay and procedural uncertainty on appellate timelines, including the Court of Appeal’s willingness to permit a late notice of appeal where the need for leave has been clarified only by the chambers ruling.

Background and business relationship

The dispute arises out of a failed business relationship between Squareflow New Media Inc. and its principal, Barend Jacobus Van Heerden, on one side, and MeatMeatGo Inc. together with Lyndon Lisitza and Callie Lisitza, on the other. The parties were once business partners. Their relationship deteriorated, leading to cross-claims over who owns the software that underpinned their business operations. The litigation in the Court of King’s Bench involves competing claims and counterclaims concerning ownership and use of this software and associated business assets, but those merits have not yet been decided in the decisions under discussion.

The Anton Piller order in the King’s Bench decision

In the underlying Court of King’s Bench decision of August 26, 2025 (the “Decision”), Squareflow New Media Inc. and Mr. Van Heerden applied, without notice, for an Anton Piller order. An Anton Piller order is an extraordinary form of pre-trial relief that allows the applicant, under strict judicial supervision, to enter another party’s premises to search for and seize evidence at risk of being destroyed before trial. Here, the respondents obtained the order on an ex parte basis, authorising a search of the MeatMeatGo parties’ premises and the seizure of property believed to contain important evidence relevant to the software-ownership dispute. An independent supervising solicitor was appointed to conduct the search and seizure to protect the rights of the party being searched and to ensure that any privileged or irrelevant material would be properly dealt with. After the order was executed and property was seized, the MeatMeatGo parties applied in the Court of King’s Bench to set aside, or “vacate,” the Anton Piller order. They argued that Squareflow and Mr. Van Heerden had failed in their duty of full and frank disclosure when they initially applied for such extraordinary relief. They also challenged the admission of an affidavit filed by the respondents in the course of the motion to vacate. The same judge who had granted the Anton Piller order ultimately declined to revoke it. In the Decision, the judge maintained the order in place and admitted the respondents’ affidavit into evidence. This left the seized material available for use as evidence in the ongoing litigation over the software and business assets.

Procedural posture and the application for directions in the Court of Appeal

Following the refusal to set aside the Anton Piller order, the MeatMeatGo parties—now prospective appellants—applied to the Court of Appeal for Saskatchewan for directions. They sought clarification whether the August 26, 2025 Decision of the Court of King’s Bench was a final order or an interlocutory one, and whether they required leave to appeal under The Court of Appeal Act, 2000. Their primary position was that the Decision should be characterised as a final order under s. 7(2) of the Act. In the alternative, they argued that, even if interlocutory, no leave was required because s. 8(2)(a)(iii) removes the leave requirement for interlocutory decisions involving “the granting or refusal of an injunction.” As a further fallback, they asked for leave to appeal if the Court concluded that it was necessary. By the time the matter came before Caldwell J.A. in chambers, the usual time for filing a notice of appeal had expired. The applicants therefore also needed relief from the time limits, so that they could still bring their proposed appeal against the King’s Bench Decision.

Final versus interlocutory nature of the orders

The chambers judge first addressed whether the orders made in the Decision were final or interlocutory. He reviewed established Saskatchewan authority distinguishing final from interlocutory orders, emphasising that an order is interlocutory if it is made during the progress of a proceeding, deals with an intermediate matter, and does not finally determine the parties’ substantive rights in the litigation. Applying this framework, he held that the order admitting the respondents’ affidavit into evidence was clearly interlocutory. It related to an evidentiary issue that arose in the course of the motion and did not finally decide any substantive right in the main lawsuit. He then turned to the core question: whether the refusal to vacate the Anton Piller order was final because, as the applicants argued, it conclusively determined the fate of the seized property and exhausted their ability in the Court of King’s Bench to contest the seizure or seek the property’s return. The applicants contended that this meant their rights in respect of that property were finally resolved. The chambers judge rejected this reasoning. He held that an order is not final merely because it conclusively disposes of the specific application that was before the chambers judge. If that were the test, almost any order would be deemed final, undermining the carefully maintained distinction between final and interlocutory decisions. Because the Anton Piller order existed only to preserve evidence for use at trial, and the refusal to vacate it did not decide the merits of the claims or defences in the underlying lawsuit, he concluded that the order was interlocutory. It dealt with the preservation of evidence, not with who ultimately owned the software or what monetary or other relief should be granted at the end of the case.

Whether the Anton Piller ruling fell within the “injunction” exception

Having found the order interlocutory, the chambers judge next considered whether the applicants nonetheless had an appeal as of right under s. 8(2)(a)(iii) of The Court of Appeal Act, 2000, which exempts from the leave requirement interlocutory decisions involving “the granting or refusal of an injunction.” The key issue was whether an Anton Piller order, and a subsequent refusal to vacate it, falls within this description. The judge noted that an Anton Piller order is recognised in Canadian law as a species of urgent injunctive relief authorising pre-trial search and seizure of evidence in civil cases. He observed that the respondents themselves had characterised their application as one for injunctive relief and that the King’s Bench judge had treated it in that way. He contrasted this with an earlier case, Bourelle v Saskatchewan Government Insurance, where an order compelling attendance at a medical examination under specific statutory and rule-based provisions was held not to be an injunction for the purposes of the same section of the Act. In Bourelle, the courts had never applied an injunction-style analytical framework, and the governing provisions did not refer to injunctions; the order was simply a procedural step, despite its compulsory nature. By contrast, Anton Piller orders are rooted in the superior court’s inherent equitable jurisdiction and are evaluated using a framework closely analogous to that used for interlocutory injunctions. The Supreme Court of Canada in Celanese laid out four essential conditions for granting such an order, including a strong prima facie case, very serious potential or actual damage to the applicant, convincing evidence that the defendant holds incriminating material, and a real possibility that the evidence will be destroyed before normal discovery can occur. The chambers judge drew parallels between these requirements and the standard RJR-MacDonald/Mosaic injunction test, which looks to a serious issue or strong prima facie case, irreparable harm, and the balance of convenience. In particular, the “real possibility” that important evidence will be destroyed was viewed as a form of irreparable harm, because once such evidence is lost it cannot be restored through damages. The judge also emphasised that Anton Piller orders, like other interlocutory injunctions, require a plaintiff’s undertaking as to damages, and must be circumscribed by detailed safeguards to protect the party being searched. In light of this, he concluded that an Anton Piller order is indeed a type of injunction for the purpose of s. 8(2)(a)(iii). As such, an interlocutory decision granting, refusing, or refusing to set aside such an order falls within the statutory category of injunction-related decisions that do not require leave to appeal.

Treatment of the affidavit ruling and incidental orders

The chambers judge recognised a second strand in the applicants’ proposed appeal: they wished to challenge not only the refusal to set aside the Anton Piller order, but also the admission of the respondents’ affidavit into evidence in the King’s Bench proceedings. Having already classified the affidavit ruling as interlocutory and not itself within any of the categories listed in s. 8(2), he addressed how such incidental orders can be raised on appeal. He held that, because the applicants had a right to appeal the main interlocutory injunction-type ruling without leave, they were entitled under the appellate rules to also challenge incidental orders made in the course of that same application. On this basis, he concluded that the applicants could include, in a single notice of appeal, both their challenge to the refusal to set aside the Anton Piller order and their attack on the admission of the affidavit.

Outcome of the chambers application and absence of monetary relief

In the result, the Court of Appeal (Caldwell J.A. in chambers) granted the MeatMeatGo parties’ application for directions in substance. He held that the King’s Bench refusal to vacate the Anton Piller order was an interlocutory order involving the granting or refusal of an injunction, so that no leave to appeal was required. Because the usual appeal period had already expired while this procedural question was being resolved, he granted the applicants leave to file their notice of appeal within 14 days of his fiat. He also confirmed that the applicants could, in that notice of appeal, include a challenge to the incidental order admitting the respondents’ affidavit. Given the unsettled state of the law on these issues and the helpful submissions from both sides, the chambers judge made no order as to costs. There was no determination of damages, no quantified monetary award, and no costs ordered in favour of either party. Accordingly, the successful party in this chambers decision is MeatMeatGo Inc., Lyndon Lisitza and Callie Lisitza, but the total monetary award or costs granted to them is nil, as no such amounts were fixed or ordered in this ruling.
