The department filed a lawsuit against the state, alleging the new piece of legislation is "unlawful and anti-consumer".
This law prohibits ISPs from blocking or slowing down access to websites and other services.
The United States Telecom Association said in a statement it supports strong net neutrality protections but thinks the matter should be left to the federal government. -Evan Greer, Fight for the FutureEvan Greer, deputy director of Fight for the Future, was among those championing the tireless work of activists, organizers, and regular citizens who pushed the bill in California and have been working to restore net neutrality protections nationwide since FCC chairman Ajit Pai, a former Verizon lobbyist and appointed by President Donald Trump, led the effort to destroy them on behalf of the telecom industry previous year. Jerry Brown speaks at a forum in Sacramento, Calif.
"Under the Constitution, states do not regulate interstate commerce - the federal government does".
Many conservatives and FCC Chairman Ajit Pai have also spoken out against net neutrality, arguing it would do more harm than good.
The law also requires companies to report their board composition to the California secretary of state and imposes a $100,000 fine if a company fails to do so. "Other states should follow California's lead, and Congress should pass the joint resolution to reverse the FCC's resoundingly unpopular repeal". The new law aims to protect internet safeguards implemented by the Obama administration, which were rolled back by the FCC past year.
State legislators began working on the bill when the Trump administration began to scale back net neutrality regulations past year, with many Democrats viewing the legislation as a victory against the White House.
In a letter to the California State Senate that was copied to the Senate Judiciary Committee, Governor Brown explained his reasoning for signing the bill despite potential legal challenges: "Recent events in Washington, D.C. - and beyond - make it crystal clear that many are not getting the message". According to the National Conference of State Legislators, almost one hundred bills and resolutions have been introduced throughout the United States. "While the Trump Administration does everything in its power to undermine our democracy, we in California will continue to do what's right for our residents".
However, Attorney General Jeff Sessions quickly reiterated the federal government is the only authority that can rule on net neutrality policies.
"I am hopeful that our incoming Legislature and governor will agree that the right to choose isn't just a slogan, but rather a commitment to improving true access to abortion for students across California", she said in a statement.
