Late last month a California Court ruled that a 2020 ballot measure that exempted ride-share and food delivery drivers from a state labor law is unconstitutional.
This ruling is grounded on strong precedent. As noted by the judge this is because the ballot measure unreasonably "limits the power of a future legislature to define app-based drivers as workers subject to workers' compensation law". This not only makes the entire measure unenforceable, but it is also likely to be upheld upon appeal.
