Apple and Epic Games Both Petition Supreme Court Over App Store Injunction

Both Apple and Epic Games have filed separate petitions with the US Supreme Court seeking review of lower court rulings in their multi-year App Store dispute, with Apple challenging a universal injunction against its developer guidelines and Epic seeking broader antitrust remedies.

Apple filed its petition for certiorari on September 28, 2023, in case number 23-344, asking the Court to overturn a district court injunction that prohibits the company from enforcing one of its contractual guidelines against all developers on the App Store's United States storefront. The Ninth Circuit Court of Appeals affirmed this injunction, reasoning that extending injunctive relief to nonparties was necessary to address Epic's alleged injury.

Epic Games filed its own petition one day earlier on September 27, 2023, in a separate case numbered 23-337, seeking Supreme Court review of the broader antitrust aspects of its lawsuit against Apple.

The Universal Injunction at Issue

The central legal question in Apple's petition concerns the scope of injunctive relief in private antitrust litigation. The district court's universal injunction prevents Apple from enforcing its anti-steering provisions — rules that historically prevented developers from directing users to alternative payment methods outside the App Store — against all US App Store developers, not just Epic Games.

Apple argues that this universal relief exceeds the bounds of traditional equity principles, which typically limit injunctive remedies to the specific parties before the court. The Ninth Circuit, however, concluded that broader relief was justified to fully redress Epic's competitive injury in the relevant market.

This disagreement touches on fundamental questions about the permissible scope of injunctive relief in cases involving platform policies that affect entire ecosystems of third-party developers.

Procedural Maneuvering

The Supreme Court has already weighed in on interim aspects of this dispute. On August 9, 2023, the Court rejected Epic's emergency request to allow the lower court's injunction to take immediate effect, permitting Apple to maintain its existing App Store payment rules temporarily while the appeals process continued.

Epic had initially sought this emergency relief on July 27, 2023, asking the Supreme Court to let the district court's order take effect immediately rather than wait for the completion of Apple's appeal.

In the Epic-initiated case 23-337, Apple has requested a 30-day extension to file its brief in opposition, which would push the deadline to December 29, 2023. Epic has opposed this extension request, suggesting the company wants to accelerate the Court's consideration of the broader antitrust questions.

Broader Context of App Store Regulation

The Supreme Court petitions arrive as mobile app store policies face increasing scrutiny from regulators worldwide. The European Union's Digital Markets Act has already compelled Apple to allow alternative app stores and payment methods in EU markets, while various US state and federal legislative proposals have targeted similar restrictions.

The technical implementation challenges around these policy changes have proven substantial. Allowing external payment processing requires new APIs, modified user flows, and complex revenue-sharing arrangements that differ significantly from Apple's integrated payment system. The security and fraud prevention implications of these changes remain contested between platform operators and regulators.

Looking at the historical arc of platform regulation, we have seen this pattern before when Microsoft faced antitrust scrutiny over Internet Explorer bundling in the late 1990s. The technical complexity of unbundling integrated platform features created lasting implementation challenges that shaped subsequent platform design decisions across the industry.

Market Impact and Developer Dynamics

The injunction's universal scope has practical implications for thousands of App Store developers who are not parties to the Epic litigation. These developers now have potential legal protection against Apple's anti-steering enforcement, even though they did not participate in the underlying lawsuit.

This dynamic creates unusual market conditions where a single company's litigation success extends benefits to competitors and non-parties, potentially encouraging similar strategic litigation approaches in other platform disputes.

The Supreme Court's eventual decisions in both cases could establish precedent for how courts balance platform operator control against developer access rights, with implications extending beyond mobile app stores to other two-sided technology markets.

What the Court Will Consider

The Supreme Court's review, if granted, would likely focus on narrow legal questions rather than broad policy implications. In Apple's case, the primary issue concerns the appropriate scope of injunctive relief in private antitrust litigation and whether universal injunctions against platform policies can be justified without all affected parties being represented in the litigation.

Epic's petition raises different questions about market definition, monopolization standards, and the application of traditional antitrust frameworks to digital platform business models.

The Court's decisions to grant or deny review in both cases will signal its appetite for addressing platform regulation questions through the judicial system, as opposed to leaving these issues primarily to legislative and regulatory processes.

The timing of the Court's review process means final decisions on both petitions would likely emerge in the Court's 2024-2025 term, providing resolution to legal questions that have shaped App Store policy development for several years. For developers and platform operators, this resolution would clarify the boundaries of permissible platform control and the enforcement mechanisms available to challenge restrictive policies.
