The California Supreme Court held yesterday that the ABC test announced in its landmark Dynamex decision – which makes it infinitely harder for businesses to classify workers as independent contractors – applies on a retroactive basis. This decision ended more than a year-and-a-half of waiting after the 9th Circuit Court of Appeals first held in May 2019 that the Dynamex test applied retroactively and then, a little less than three months later, withdrew its opinion and asked the California Supreme Court to decide the matter.
