California could become a battleground for net neutrality with the U.S. Department of Justice challenging a new state law that prohibits Internet providers from slowing customer speeds.  

Gov. Jerry Brown signed a bill Sunday to provide net neutrality protections, which was followed immediately by the federal lawsuit.  

Senate Bill 822 bars Internet service providers from slowing, or throttling, speeds, blocking access to lawful content and offering fast lanes for Google, Facebook and Netflix.  

"Once again, the California legislature has enacted an extreme and illegal state law attempting to frustrate federal policy," U.S. Attorney General Jeff Sessions said in a statement. "The Justice Department should not have to spend valuable time and resources to file this suit."
