Quick Summary

Doctors and insurance firms have filed a lawsuit against California's new healthcare tax, arguing it violates Proposition 35 from 2024. The MCO tax, which will increase premiums by $100 annually per individual and up to $400 for a family of four, was passed in June and signed into law by Governor Gavin Newsom. The plaintiffs claim the state is imposing an illegal “massive tax increase” on healthcare costs for working families, while California officials assert the tax is necessary due to federal funding cuts under President Trump.

Story summary

The California Medical Association (CMA) and California Association of Health Plans (CAHP) filed a lawsuit against Gov. Gavin Newsom and the California Legislature for allegedly violating Proposition 35, a 2024 initiative approved by voters. The lawsuit targets a newly enacted healthcare tax on managed care organizations (MCOs), which is expected to increase insurance premiums by $8.85 per month per enrollee, or approximately $100 annually for an individual and $400 for a family of four. Both groups argue that the new tax circumvents Prop. 35’s restrictions on healthcare taxes and their designated purposes, potentially burdening California families financially. The CAHP contends this lawsuit aims to uphold the principle that California should not resolve budget shortfalls by imposing heavy costs on healthcare expenses for working families.

🔮 A new California healthcare tax that’s expected to jack up family premiums by hundreds of dollars annually isn’t even legal, according to a group of doctors and insurance firms.
🔮 When asked about his stance on the death penalty following the Pike debacle, a Becerra campaign spokesperson referred the California Post Thursday to a tweet from May where he praised Gov. Gavin Newsom’s moratorium on executions.
🔮 The magazine piece — in which Newsom compared himself to Bill Clinton and claimed he’s written “36 pages of ideas” on national priorities — noted that investigators may be looking into money that was piped from a Sonoma County native tribe to his wife’s gender-focused nonprofit.
🔮 In another post that has since been deleted, the Corgi employee shared that she would “not attempt to police” those who use the N-word — which spurred furious X posts labeling her a “mean girl” and an apparent condemnation by another staffer, Ella Schlaghecke.
🔮 The prop, pushed by the union after a similar legislative effort failed last year, would require clinics to spend 90% of their revenues on patient care, allowing the state to fine clinics that don’t comply.
🔮 This is a developing story and will be updated.
🔮 Netflix co-founder Reed Hastings has cut a seven-figure check to block a California ballot measure that would establish strict ID requirements for voters.
🔮 Concerns about rapidly advancing AI technology exploded to the forefront this month when Jacob Coxon, a former researcher at Anthropic at OpenAI, quit his role over fears that the tech could break free of human control and ultimately cause exctinction.
🔮 But a similar percentage of voters were in favor of two “poison pill” measures that would nullify key parts of the billionaire tax if they receive more votes, the poll found.
