MDL Number 23-md-3073

Presiding Judge:

Case Summary


The United States Judicial Panel on Multidistrict Litigation issued a Transfer Order on June 2, 2023, assigning MDL No. 3073 to this Court for coordinated or consolidated pretrial proceedings, and describing this multidistrict litigation as follows. These putative class actions share complex factual questions arising from T-Mobile’s announcement on January 19, 2023, that a data security breach of its network occurred in late 2022 in which an unauthorized actor accessed and acquired files on its network, including personally identifiable information of 37 million current and former customers. Common factual questions will include: T-Mobile’s data security practices and whether those practices met industry standards, how the unauthorized actor obtained access to T-Mobile’s system, the extent of the personal information affected by the breach, and when T-Mobile knew or should have known of the breach.
