Dynamex Operations West v. Superior Court (2018)
The California Supreme Court adopted the ABC test for determining whether workers are employees or independent contractors. The test requires companies to prove workers are free from control, perform work outside the company's core business, and operate independently.
The ruling upended gig-economy business models in California and led directly to Assembly Bill 5 in 2019.
AB5 codified the ABC test, and the Lyft and Uber lawsuits followed when the companies continued classifying drivers as independent contractors.
The Dynamex ABC test is the legal standard the state used to argue Lyft misclassified its drivers.
