Political law firm Nielsen Merksamer Parrinello Gross & Leoni has drafted a ballot initiative that would shield app-based ride-hailing and delivery services from a new California law that makes it tougher for companies to label workers as independent contractors.

Lyft, Uber, DoorDash and Instacart are backing the “Protect App-Based Drivers and Services Act,” a proposed 2020 ballot measure aimed at circumventing the California Supreme Court’s employee friendly ruling in Dynamex and the subsequent state legislation codifying much of that opinion, Assembly Bill 5.
