The over 9000 entry court docket for the class. Tons of defendants, tons of plaintiffs, tons of cases merged into this one for the purpose of hearing similar claims/expediting expert witness deposition and discovery, etc.
Other lawsuits by the 7-Eleven and Home Depot and Grubhub groups are attempting to be continued. Grubhub is trying to remand out their case from the settlement on the grounds of all mutual claims being addressed in the settlement and other claims deserving jury trial.
Several merchants plan to object to the proposed settlement with a schedule (as of now, subject to change, these things are frequently delayed by mutual agreement of plaintiff/defendant attorneys and the court) of April 26th for objections, replies to objections May 13th, and an in-person hearing with oral argument for preliminary approval of the proposed settlement on June 13th.
Again though - don't be surprised if these dates get pushed out.
