TRANSFER ORDER AND ORDER DENYING TRANSFER

Before the Panel:* Before the Panel are two dockets involving a series of data breaches of Salesforce customers that occurred at various times throughout 2025. Threat actors allegedly used social engineering to gain access to the Salesforce databases controlled by Allianz Life Insurance Company of North America (Allianz); Farmers Insurance Exchange, Farmers Group, Inc., and Farmers New World Life Insurance Company (collectively Farmers Insurance); Louis Vuitton North America, Inc. (Louis Vuitton); and Trans Union, LLC (TransUnion). Some plaintiffs allege that dozens of additional Salesforce customers have similarly fallen victim to social engineering attacks and had data exfiltrated from their Salesforce databases. Plaintiffs in five actions listed on Schedule A move under 28 U.S.C. § 1407 to centralize 41 actions involving the theft of data from a Salesforce customer’s Salesforce database. This motion was docketed as MDL No. 3164, Jn re: Salesforce, Inc., Customer Data Security Breach Litigation.| One of those Salesforce customers, TransUnion, later moved on October 3, 2025, to centralize 53 actions arising from the breach affecting it. Two of those 53 actions are from MDL No. 3164, and the rest are potential tag-along actions to MDL No. 3164. This motion was docketed as MDL No. 3170, Jn re: Trans Union, LLC, Customer Data Security Breach Litigation. The two competing motions proposed the Northern District of California and the Northern District of Illinois as the transferee district for a Salesforce MDL and TransUnion MDL, respectively.

* Judge Madeline Cox Arleo did not participate in the decision of this matter. Additionally, one or more Panel members who could be members of the putative classes in this litigation have renounced their participation in these classes and participated in this decision. ' After briefing concluded, movants in MDL No. 3164 sought to withdraw their motion to centralize all Salesforce-customer-related actions in a single multi-defendant MDL, explaining that information uncovered during briefing makes centralization inappropriate. The Panel Clerk denied that motion because several plaintiffs had responded in support of the multi-defendant MDL proposed in MDL No. 3164.

The responding parties take a variety of positions. The main areas of disagreement are whether a multi-defendant SalesforceMDL is appropriate, whether the TransUnion-related actions should be centralized in a separate MDL, and the selection of a transferee district. Plaintiffs in 25 actions and 23 potential tag-along actions support the proposed Salesforce MDL but differ on transferee district. Plaintiffs in six actions and fourteen potential tag-along actions support centralization in the Northern District of California. The other plaintiffs supporting a Salesforce MDL variously request the Northern District of Illinois and the District of Minnesota. Plaintiffs in fifteen actions and five potential tag-along actions—including movants—either oppose a Salesforce MDL, oppose transfer of their actions to a Salesforce MDL, or oppose inclusion of actions against a specific Salesforce-customer defendant in any Salesforce MDL. Plaintiffs in twenty actions support a TransUnion-specific MDL but differ on transferee district. Plaintiffs in eighteen of those actions support centralization in the Northern District of Illinois. The other plaintiffs supporting a TransUnion MDL propose the Northern District of California. Plaintiffs in nine actions and one potential tag-along action oppose creation of a standalone TransUnion MDL. All responding defendants oppose the proposed Salesforce MDL to some degree. Defendants Salesforce, TransUnion, Allianz, and Farmers Insurance oppose creation of a Salesforce MDL. Louis Vuitton and Workday oppose transfer of actions against them to a Salesforce MDL. Farmers Insurance, Pandora, Salesforce, and Workday take no position as to a TransUnion MDL but request separation and remand under Section 1407(a) of the claims against themif we create a TransUnion MDL. On the basis of the papers filed and the hearing session held, we conclude that centralization of MDL No. 3164 (Salesforce) is not necessary for the convenience of the parties and witnesses or to further the just and efficient conduct of the litigation. We do, however, find that the actions listed on Schedule B involve common questions of fact and that centralization of MDL No. 3170 (TransUnion) in the Northern District of Illinois will serve the convenience of the parties and witnesses and promote the just and efficient conduct of the litigation. The actions listed on Schedule A present few common questions of fact. Proponents of a Salesforce MDL argue that all actions raise common questions of fact surrounding a vulnerability in the Salesforce platform. We are not persuaded that any common questions of fact that may exist justify centralization of a large, multi-defendant MDL. The actions allege separate data breaches affecting multiple different Salesforce customers. Each breach involved a social engineering attack directly on a Salesforce customer, not an exploit of Salesforce itself with downstream consequences. Different facts will emerge for each Salesforce-customer defendant regarding how the attacks were conducted, which employee was involved, how the employee reacted, whether that defendant had procedures for guarding against social engineering attacks, how that defendant responded to the incident, and which types of personally identifiable information (PII) were impacted. Most of the complaints do not mention Salesforce, let alone allege that a common vulnerability in the Salesforce platform was a crucial factor in each data breach. We also find centralization unnecessary because of the parties’ ongoing self-organization efforts. See In re Cash Sweep Programs Cont. Litig., 766 F. Supp. 3d 1346, 1350 (J.P.M.L. 2025) (finding that “the ongoing self-organization of this litigation on a defendant-specific basis further weighs against centralization”). Litigation hubs have emerged for each Salesforce-customer defendant in the defendant’s home district: the Northern District of Illinois for TransUnion, the District of Minnesota for Allianz, the Central District of California for Farmers Insurance, the Northern District of California for Salesforce, and the Southern District of New York for Louis Vuitton.2 If discovery of Salesforce becomes necessary, it can be handled informally. See In re Accellion, Inc., Customer Data Sec. Breach Litig., 543 F. Supp. 3d 1372, 1374 (J.P.M.L. 2021) (“Proponents of centralization argue that even in the actions in which Accellion is not named, it will be involved in some third-party discovery. But we are persuaded that such discovery can be informally coordinated.”). In our view, a multi-defendant Salesforce MDL will hinder, rather than promote, the just and efficient conduct of the litigation. Proponents of a Salesforce MDL argue that centralization is necessary to eliminate duplicative discovery. We disagree that any potential duplicative discovery warrants creation of a potentially unwieldy MDL comprised of all Salesforce customers. Each breach appears unique, and the claims against each customer defendant that was breached may turn on individualized discovery as to that customer defendant.
