Unreported / Non-Citable
Background
Zane Murdock, representing himself, sued Meta Platforms, Inc. in the U.S. District Court for the Northern District of California, alleging that Meta violated federal antitrust laws by restricting his Facebook business account. He brought claims under Sections 1 and 2 of the Sherman Act, asserting that the account restriction restrained his access to trade or commerce. Meta moved to dismiss the complaint in its entirety, arguing that Murdock lacked antitrust standing and failed to state a claim.
Murdock opposed the motion and separately moved to strike Meta's reply brief, contending that it omitted procedural information required by the Civil Local Rules, improperly used the term "Sherman Act," introduced new citations and arguments, and that Meta had improperly served him both electronically and by mail when he preferred electronic service only. The court addressed the motion to strike first before turning to the merits of the dismissal motion, and it assumed the reader's familiarity with the facts, legal standards, and the parties' arguments.
The Court’s Holding
The court denied the motion to strike, finding none of Murdock's reasons valid. It explained that claims under 15 U.S.C. Sections 1 and 2 are indeed Sherman Act claims, that Meta's reply raised no new arguments but merely clarified it was not pursuing an argument Murdock had mentioned, and that nothing prohibited dual service by mail and electronically—though Meta agreed to use only electronic service going forward. The court also noted Murdock had shown no prejudice from any procedural errors, which is required before a reply brief may be stricken.
On the merits, the court held that Murdock lacked antitrust standing because he had not alleged antitrust injury—harm to the competitive process itself, not merely to himself as an individual competitor. The restriction of a single account, the court explained, is routinely found insufficient to show antitrust injury. Even if standing existed, the complaint failed to state a Section 1 claim because Murdock alleged no contract, combination, or conspiracy with any other person or entity, and it failed to state a Section 2 claim because he identified no relevant market and did not adequately allege willful acquisition or maintenance of monopoly power.
The court granted Meta's motion to dismiss with leave to amend, giving Murdock until November 13, 2026 to file an amended complaint correcting the identified deficiencies. The court warned that any amended complaint must be complete in itself and cannot incorporate prior pleadings, and that if no amended complaint is filed by the deadline, the claims will remain dismissed with prejudice and the case will be closed. Because dismissal was required on standing and pleading grounds, the court did not reach Meta's additional arguments.
Key Takeaways
- Antitrust standing requires antitrust injury—harm to competition itself, not just harm to an individual competitor—and restricting a single social media business account does not satisfy that requirement.
- A Section 1 Sherman Act claim requires pleading a contract, combination, or conspiracy with another person or distinct business entity; conclusory allegations that a defendant "conspires to restrain" trade are insufficient.
- A Section 2 monopolization claim requires identifying a relevant market and alleging the defendant's monopoly power within it; failing to define any market is fatal.
- Motions to strike reply briefs require a showing of prejudice, and disagreements over terminology or service methods do not qualify.
- Pro se plaintiffs receive leave to amend but must file a complete, self-contained amended complaint by the court's deadline or face dismissal with prejudice.
Why It Matters
This order reinforces the consistent line of federal district court decisions holding that individual account restrictions by large platforms do not give rise to antitrust claims absent allegations of harm to competition as a whole. It illustrates the high threshold pro se plaintiffs face when attempting to frame individual grievances with platform moderation or account decisions as federal antitrust violations.
The decision also provides a useful procedural reminder that motions to strike require demonstrated prejudice and that amended complaints must stand on their own without incorporating earlier filings—a rule that applies with equal force to self-represented litigants.
