The consolidation brings together separate class action lawsuits filed by Rebecca Blount, Cheryl McCulley, Robert Bales, Kellie House, and Mark Weibush against Cerner Corp., which operates as Oracle Health. The cases also name additional defendants including Christus Health and Aultman Health Foundation, suggesting the data breach affected multiple healthcare systems that use Cerner's electronic health record platform.
Phillips determined that consolidation was appropriate under Federal Rule of Civil Procedure 42, noting in her order that the move was "consistent with previous Orders consolidating other similar cases." The judge directed that all future filings be made only in the lowest-numbered case, with parties using the caption "In re: Cerner/Oracle Data Breach Litigation" rather than listing individual case captions.
The four cases were filed separately in the Western District of Missouri between 2025 and 2026, with case numbers ranging from 25-00259-CV-W-BP to 26-00278-CV-W-BP. Phillips ordered the consolidation for "at least all pretrial purposes," leaving open the possibility that cases could be separated for trial.
The consolidation signals the potential scope of the alleged data breach at Cerner, now owned by Oracle, which provides electronic health record systems to hospitals and healthcare providers nationwide. The move will likely streamline discovery and motion practice while plaintiffs seek to establish the extent of any data compromise and resulting damages.
