555 F.Supp.3d 1372
J.P.M.L.
2021
Read the full case

Background

  • 19 related antitrust actions pending in 16 districts (advertiser, publisher, and a 15‑state parens patriae action led by Texas) allege Google monopolized or suppressed competition in online display advertising.
  • Centralization motion under 28 U.S.C. § 1407 filed by Google (seeking Northern District of California); Panel selected the Southern District of New York (SDNY) instead.
  • Common core allegations: relevant‑market definition for display advertising, Google’s ad tech products and alleged interoperability barriers, acquisitions (e.g., DoubleClick), alleged tying, and an alleged 2018 Google–Facebook agreement that neutralized “header bidding.”
  • Panel found substantial overlap in fact discovery (including third‑party discovery of Facebook, Amazon, and regulators) and risk of inconsistent pretrial rulings, favoring an MDL.
  • The State of Texas action (state enforcement) sought to exclude itself due to sovereign interests, advanced discovery posture, and proposed withdrawal of federal damages; Panel nonetheless included it in the MDL.
  • MDL No. 3010 assigned to Judge P. Kevin Castel in the SDNY; Google’s request to transfer the State of Texas action for trial under § 1407(h) was denied without prejudice pending further development.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether centralization under § 1407 is warranted and where Many plaintiffs opposed MDL or favored multiple, separate forums (or their home districts) citing factual differences and case‑management concerns Google: single MDL needed to avoid duplicative discovery and inconsistent rulings; sought NDCA Centralization warranted; MDL established in SDNY for coordinated pretrial proceedings
Whether the State of Texas action should be included in the MDL States: sovereign enforcement, more advanced discovery, dropped federal damages, and need for expeditious resolution justify exclusion Google: State action shares the same factual core and overlapping remedies; should be centralized Included in MDL despite states’ objections; sovereign status and posture not dispositive
Whether separate MDLs for advertisers and publishers are required Some plaintiffs urged separate tracks or separate MDLs because of different issues and damages models Google: substantial overlap in core factual issues (market definition, effects, damages apportionment) supports single MDL Single MDL is appropriate; transferee court can manage differences with case‑management tools
Whether informal coordination or § 1404 transfers are sufficient alternatives Plaintiffs suggested informal coordination or individual § 1404 transfers could avoid centralization Google: informal coordination impracticable across 16 districts and multiple counsel; § 1404 impractical here Informal coordination and § 1404 transfer are inadequate substitutes for a § 1407 MDL
Whether to transfer the State of Texas action for trial under § 1407(h) Google sought transfer for trial under § 1407(h) based on operative pleading asserting § 4C damages States moved to amend to drop § 4C; parties disputed posture Denied without prejudice: record insufficient now; decision reserved for transferee court after further development
