What is a Multidistrict Litigation (MDL)?


Zoll & Kranz, LLC attorneys represent individuals in multidistrict litigation (MDL). MDL has a combined discovery phase in which evidence is exchanged between plaintiffs and defendants. However, unlike class actions, MDL holds separate trials on behalf of each individual plaintiff. Zoll & Kranz, LLC splits the product liability cases into two categories, dangerous drugs and defective medical devices.
