In Castellanos v. State of California the Supreme Court is expected to decide the validity of Proposition 22, the 2020 initiative — heavily financed by Uber and Lyft — that classifies app-based drivers as independent contractors instead of employees. (See here.) Specifically, the court has limited the issue to: “Does Business and Professions Code section 7451, which was enacted by Proposition 22 (the ‘Protect App-Based Drivers and Services Act’), conflict with article XIV, section 4 of the California Constitution [which gives the Legislature the “plenary power . . . to create, and enforce a complete system of workers’ compensation”] and therefore require that Proposition 22, by its own terms, be deemed invalid in its entirety?” (Links added.)

Castellanos is a high profile case by any measure. One measure is the number of amicus curiae briefs it has attracted. There are 21 of them.

Former Justice Joseph Grodin is a named amicus on one of the briefs. He has been an amicus in U.S. Supreme Court cases (see here and here) and a number of other California Supreme Court cases as well.

Here’s a list of the amici.

The court last week granted extensions to June 3 for the parties to respond to the amicus briefs.

The court sent its oral argument letter seven weeks ago. Based on counsel’s responses to the letter and the court’s responses to the responses, it appears the Castellanos argument will not be on the June calendar, but could be on the early-May or late-May calendars. It is not unheard of to have an oral argument before the filing of responses to amicus briefs. If the case is not argued in May, it probably won’t be heard until September, the next calendar after June.
