What happened

A proposed class action was filed by Jane Doe individually and on behalf of all similarly situated individuals against Keffer Development, LLC, Malone University, and Matthew Weiss. The case appears to concern a data security breach, as it was transferred to the Eastern District of Michigan as part of MDL No. 3159, titled 'Keffer Development Services, LLC Data Security Breach Litigation.' These are allegations in a newly filed case, not proven facts.

Do you qualify?

No settlement exists yet, so there is nothing to file and no class definition to check. If the case settles, the settlement will define exactly who qualifies — watch this case and we'll let you know.

How to file

There is no claim to file yet. If this case reaches a settlement, a claim process will open — usually with an official settlement website and a filing deadline.
