Florida would impose one of the nation’s strictest social media bans on minors if it survives expected legal challenges, under a bill signed by Republican Gov. Ron DeSantis on Monday.

The bill would prohibit children under 14 from using social media accounts and require 15- and 16-year-olds to obtain parental permission. The proposal was watered down slightly after DeSantis vetoed a proposal earlier this month, a week before the end of the annual legislative session.

The new law is Republican Speaker Paul Lehner’s top legislative priority. Effective January 1st.

“Children with their developing brains don’t have the ability to know that they are being hooked on these addictive technologies and to see the harm and stay away from it, so we have to step in for them,” Rayner said at a Jacksonville school said at the bill signing ceremony.

The bill DeSantis vetoed would ban minors under 16 from using popular social media platforms, regardless of parental consent. But before vetoing it, he worked out compromise language with Renner to allay the governor’s concerns, and the Legislature sent DeSantis a second bill.

Several states have considered similar legislation. In Arkansas, a federal judge in August blocked enforcement of a law that would have required parental consent for minors to create new social media accounts.

Supporters in Florida hope the bill will survive legal challenges because it would ban social media formats based on addictive features like notification alerts and auto-playing videos, rather than on their content.

Reyna said he expected social media companies to “sue the second agreement after it’s signed.” But you know what? We’re going to defeat them. We will beat them and we will never stop. ”

DeSantis also acknowledged that the law will be challenged on First Amendment issues and expressed regret that the Stop the Woke Act, which he signed into law two years ago, was recently struck down by an appeals court with a majority of Republican-appointed justices. They ruled that banning private companies from discussing racial inequality in employee training violated free speech rights.

“Any time I see a bill, if I think it’s unconstitutional, I’m going to veto it,” said attorney DeSantis, who said he was confident the social media ban would be upheld. “We’re not only satisfied with me, but I think we’re satisfied with the fair application of the law and the constitution.”

The bill passed the House and Senate overwhelmingly, with some Democrats joining most Republicans in supporting the measure. Opponents argue it is unconstitutional and that the government should not interfere with parents’ decisions about their children.

“This bill goes too far in taking away parental rights,” Democratic Rep. Anna Eskamani said in a press release. “Instead of banning social media access, we need to ensure improved parental oversight tools and improved access to data to stop bad actors while making significant investments in Florida’s mental health systems and programs.”
