The Department of Justice is filing a lawsuit against Calif over its new net neutrality protections, hours after Gov. Jerry Brown signed the bill into law. The CA law would offer the strictest protections in the country, and could serve as a blueprint for other states. Under the law, internet service providers will not be allowed to block or slow specific types of content or applications, or charge apps or companies fees for faster access to customers. DoJ says the CA law is "attempting to subvert the Federal Government's deregulatory approach" to the internet. Barbara van Schewick, a professor at Stanford Law, says the CA bill is on solid legal ground. CA is the 3d state to pass its own net regulations, following WA and OR. However, it is the 1st to match the thorough level of protections that had been provided by the Obama-era federal net neutrality regs repealed by the Trump FCC.
