The scores of class actions filed since news broke that information of 500 million Marriott International Inc. guests was compromised will be consolidated in a federal court in Maryland.

Marriott is headquartered in Maryland and the majority of cases filed so far are in that district, the Judicial Panel on Multidistrict Litigation ruled Feb. 6.

Judge Paul W. Grimm will oversee the MDL in the U.S. District Court for the District of Maryland.

About 80 consumer class actions filed across the country allege Marriott failed to protect customers’ data and waited too long to inform them of the breach.

One class action was filed on behalf of investors alleging security fraud. But the panel determined that the case should be included in the MDL because it will involve overlapping factual issues and discovery about what Marriott knew of Starwood’s database security.

Baker Hostetler LLP represents Marriott.

The case is In re Marriott Int’l, Inc., Customer Data Sec. Breach Litig., J.P.M.L., No. 2879, consolidation motion granted 2/6/19.
