Apple filed a 12-page reply brief with the Supreme Court on June 9, pushing back against Epic Games' attempt to kill the company's latest appeal and arguing that the legal fight over App Store commission rates deserves high court review before June ends. The petition will be considered at the Supreme Court's June 25 conference — a closed-door vote that could determine whether the nation's highest court takes up a case that will set binding antitrust precedent for every platform operator in the country, not just Apple.
The stakes extend further than the Apple-Epic dispute suggests. At the center of Apple's argument is a question about civil contempt law that reaches across the entire federal court system: can a company be held in contempt for violating the purpose of an injunction when the text of that order never addressed the conduct at issue? The Ninth Circuit says yes. Other federal circuits say no. If the Supreme Court accepts the case and resolves that split in Apple's favor, the enforcement power of antitrust injunctions nationwide weakens — not just for App Store cases, but for every litigant subject to a federal court order.
What Apple's Reply Brief Actually Argues
The brief responds to Epic's 35-page opposition filed June 4, in which Epic urged the Supreme Court to reject Apple's petition. Apple's lawyers focused on two points.
On the contempt question, Apple argues that the 2021 injunction it received prohibited specific anti-steering practices — blocking developers from including buttons, external links, or other calls to action directing users to off-platform payment options. The injunction's text, Apple says, said nothing about commissions. The Ninth Circuit acknowledged that the order did not address commissions, but upheld the contempt finding anyway by applying the principle that a party can violate the "spirit" of an injunction even when the order's text does not prohibit the specific conduct. Apple calls that standard legally unsound and in direct conflict with the text-based contempt standard applied in other circuits — a conflict that qualifies as a circuit split and gives the Supreme Court a specific reason to grant review.
On the Trump v. CASA, Inc. precedent — a 2025 Supreme Court ruling that Epic cited in its opposition — Apple's reply argues that the decision explicitly states it has no bearing on antitrust cases, making Epic's reliance on it inapplicable.
The Contempt Finding the Supreme Court Would Review
The contempt question has a documented history. After the 2021 injunction took effect in January 2024, Apple did not simply comply with it. Instead, the company implemented a new commission structure charging 27% on purchases made through external links — a rate only three percentage points lower than the 30% it had previously charged through its own in-app purchase system. When combined with payment processor fees, developers received little or no financial benefit from linking out.
On April 30, 2025, U.S. District Judge Yvonne Gonzalez Rogers found Apple in civil contempt, determining the company had willfully violated the injunction with the express intent to preserve its revenue stream through new anticompetitive barriers. The ruling was remarkable in scope: the judge found that Apple's VP of Finance, Alex Roman, submitted false testimony during the proceedings, and she referred both Roman and Apple's conduct to the US Attorney for the Northern District of California for potential criminal contempt investigation. Judge Gonzalez Rogers summarized the company's decision-making directly: Tim Cook chose poorly.
In December 2025, the Ninth Circuit upheld the contempt finding but modified the remedy. The appeals court reversed the district court's outright prohibition on any commission and sent the case back to Judge Gonzalez Rogers to determine a reasonable rate Apple could charge on purchases made through external links — the proceeding now pending below.
Apple's Supreme Court petition, filed May 21, 2026, seeks to overturn the contempt designation itself before those rate proceedings advance further.

Who This Injunction Covers — and Why Apple Objects
A second argument in Apple's petition concerns the injunction's geographic and commercial scope. Apple contends the order extends to millions of registered worldwide developers who had no involvement in the Epic case, including competitors of Epic such as Microsoft and Spotify. Epic never filed a class action and never demonstrated that enjoining Apple's conduct against all other developers was necessary to provide Epic with relief. Apple argues the Supreme Court should clarify that injunctions in individual antitrust cases cannot automatically extend to all parties in an industry.
Epic CEO Tim Sweeney has described Apple's series of appeals and stays as five years of stall tactics, and argued in a May statement that Apple's own Supreme Court filings confirm the company deliberately designed its compliance to prevent the competition the 2021 injunction was meant to restore. In March 2026, Proton AG — a Swiss privacy software company — joined a developer class-action lawsuit against Apple, alleging that the App Store's commission structure forces developers to either shrink their margins or raise prices for consumers.
What Happens on June 25 and After
The June 25 Supreme Court conference is not a ruling on the merits. The nine justices will vote privately on whether to grant certiorari — to accept the case for argument. A grant requires four votes. If granted, the case would likely be scheduled for argument in the court's October 2026 term, with a final decision on the underlying questions coming no earlier than late 2026 or early 2027.
Apple has stated it will continue operating under the current zero-commission structure for external purchases while the petition is pending, so developers face no immediate change in the fee environment regardless of the conference outcome.
One significant context point: the Supreme Court previously declined to hear both Apple's and Epic's appeals in January 2024. Apple's lawyers acknowledge this in their brief but argue that the current petition is categorically different — it targets the contempt finding specifically rather than the underlying injunction, and it presents a circuit split on a contempt standard that other circuits affirmatively reject. Whether the justices find that distinction persuasive will be known within two weeks.
Can the Supreme Court Change What App Store Developers Pay?
The commission rate that developers ultimately pay on external purchases depends directly on the outcome of the rate-determination proceeding before Judge Gonzalez Rogers — which remains paused while the Supreme Court considers Apple's petition. If the Supreme Court grants certiorari and ultimately rules for Apple on the contempt question, the contempt designation would be erased, and the legal foundation for imposing any constraint on Apple's commission rate would be significantly weakened. If the Supreme Court declines the petition, rate proceedings resume and Judge Gonzalez Rogers determines what commission Apple may charge.
Global regulators are watching. Apple has acknowledged in its own filings that the outcome could influence commission policies in markets beyond the United States.
Frequently Asked Questions
What is the Apple vs. Epic App Store lawsuit about?
The dispute began in August 2020 when Epic deliberately bypassed Apple's in-app purchase system inside Fortnite, prompting Apple to remove the game and Epic to sue over antitrust violations. Apple won most counts at trial, but a federal judge ordered Apple to stop blocking developers from linking to external payment options. Apple was later found in civil contempt for implementing a workaround that nearly replicated its original 30% commission through other means. The case is now before the Supreme Court on the question of whether that contempt finding was legally proper.
Will the Supreme Court hear the Apple Epic case?
The Supreme Court will consider Apple's petition at its June 25 conference. The court previously declined to hear an earlier Apple petition in January 2024. Apple's current argument centers on a circuit split — differing contempt standards between the Ninth Circuit and other federal circuits — which is one of the primary reasons the Supreme Court grants review. A decision on whether to accept the case is expected before the justices recess in late June or early July.
What happens to App Store commissions if Apple wins at the Supreme Court?
If the Supreme Court rules for Apple on the contempt question, the legal basis for imposing commission constraints would weaken substantially. Apple could then argue it is entitled to charge commissions on external purchases without the burden of a contempt designation. If the court rules against Apple or declines the case, the district court proceeds to determine what commission rate Apple may charge on link-out purchases. Apple is currently charging zero commission on external purchases while the petition is pending.
What does this case mean for developers beyond Epic Games?
Apple argues the injunction was improperly extended to cover millions of worldwide App Store developers who were never part of the Epic lawsuit. The Supreme Court's decision on injunction scope could determine whether antitrust remedies in individual cases can be applied across entire platforms. Proton AG joined a developer class-action against Apple in March 2026, and regulators in the European Union, United Kingdom, and India are all running parallel proceedings on App Store competition practices.
