Years after an insolvency proceeding is closed, can a solvent co-lessee/working interest participant (WIP) still be on the hook for their former partner’s share of unpaid Crown royalties? A recent Alberta Court of Appeal decision to allow an appeal in <a href="https://www.canlii.org/en/ab/abca/doc/2025/2025abca181/2025abca181.html">Spartan Delta Corp v Alberta (Energy and Minerals), 2025 ABCA 181</a> [Spartan Delta], raises concerns around whether the answer to such question can be 'yes'. The oil and gas industry is closely tracking the outcome of this appeal (anticipated to be heard in Fall 2025) on the basis that if the appeal were to be granted it would create uncertainty for upstream oil & gas joint interest owners as to the impact of insolvency proceedings on existing liabilities (and would have implications for purchasers and WIPs alike in relation to oil & gas M&A out of insolvency proceedings).

In late May, the Supreme Court of Canada (the SCC) denied an application for leave to appeal a decision of the Court of Appeal of Alberta, which, in turn, had denied leave to appeal of the decision of the Court of King’s Bench of Alberta in Re Mantle Materials Group, Ltd, 2023 ABKB 488 (Mantle KB). The decision in Mantle KB held that the interests of secured creditors are subordinate to environmental obligations pursuant to the Environmental Protection and Enhancement Act, thus confirming that the priority of environmental obligations determined by the SCC in Orphan Well Association v Grant Thornton Ltd, 2019 SCC 5 applies beyond the oil and gas industry.

This week’s highly anticipated decision of the Alberta Court of Appeal in Qualex-Landmark Towers Inc v 12-10 Capital Corp, 2024 ABCA 115 limits the application of Orphan Well Association v Grant Thornton Ltd, 2019 SCC 5 to regulators inside formal insolvency proceedings rather than private litigants and denies a common law "super priority" for environmental obligations of private litigants over secured claims.

The Supreme Court of Canada will hear Pharmascience Inc v Janssen Inc on October 9, 2025, a case that could reshape the scope of patentable subject matter in Canada. At issue is whether a dosing regimen for a pharmaceutical product constitutes an unpatentable method of medical treatment or a valid invention under the Patent Act. The Federal Court and Federal Court of Appeal upheld the patent&rsquo;s validity, but Pharmascience has challenged this position. With several industry groups granted intervenor status, the case is expected to have significant implications not only for the pharmaceutical industry but also for broader questions of what qualifies as an &ldquo;invention,&rdquo; including computer-implemented and AI-related technologies.

A recent decision of the US Bankruptcy Court in Re: Iovate Health Sciences International Inc. provides important insights for Canadian companies involved in cross-border restructurings. The case addresses how debtor companies can rebut the presumption that their &ldquo;center of main interests&rdquo; (COMI) is located at their registered office when seeking Chapter 15 recognition in the United States. Chief Judge Glenn reaffirmed that COMI is determined by a non-exhaustive set of factors, including management, assets, creditors and creditor expectations, and may also be influenced by pre-filing restructuring activities.

The Alberta Court of Appeal&rsquo;s decision in Tempo v. Man-Shield confirms that equitable set-off is a true defence capable of precluding summary judgment in construction disputes. The ruling emphasizes that where claims and cross-claims are inseparably connected, courts must account for both to avoid unjust outcomes. This case provides important guidance for contractors, subcontractors and counsel navigating payment disputes and litigation strategy in the construction sector
