Meta Platforms successfully overcame an appeal from Children's Health Defense, an anti-vaccine organization established by Robert F. Kennedy Jr., which contested the company's censorship of Facebook posts disseminating misinformation regarding the effectiveness and safety of vaccines.

In a ruling issued on Friday, the 9th U.S. Circuit Court of Appeals in Pasadena, California, determined that the nonprofit failed to demonstrate that Meta collaborated with or was pressured by federal authorities to suppress dissenting views on vaccines that challenge "government orthodoxy."

Children's Health Defense initiated legal action in 2020, asserting that Meta infringed upon its constitutional rights by labeling "vaccine misinformation" as false and revoking its advertising privileges on Facebook.

Meta's measures included restricting users from sharing assertions that COVID-19 vaccines are ineffective and directing viewers of Children's Health Defense posts to the World Health Organization for accurate information regarding COVID-19.

Circuit Judge Eric Miller, appointed by former Republican President Donald Trump, articulated for the appeals court that Meta operates as a "purely private" entity with a First Amendment right to refrain from promoting perspectives it deems objectionable.

"Meta evidently believes that vaccines are safe and effective and that their use should be encouraged," Miller stated. "It does not forfeit the right to advocate for those views simply because they align with government positions."

The court also dismissed Children's Health Defense's allegations against the Poynter Institute and Science Feedback, organizations that assist Meta in assessing the accuracy of Facebook content. Kennedy, an independent candidate for the U.S. presidency, played a role in supporting Children's Health Defense's appeal.

In August 2022, Meta removed the group's accounts from both Facebook and Instagram. Following the ruling, Children's Health Defense expressed disappointment and is contemplating its legal options.

Its general counsel, Kim Mack Rosenberg, remarked that the First Amendment "seems hollow" when the only speech that is protected and amplified "reinforces the prevailing narrative."

Meta and the legal representatives for the company located in Menlo Park, California, did not promptly reply to inquiries for comments. Circuit Judge Daniel Collins, who was appointed by Trump, expressed dissent regarding the ruling, indicating that Children's Health Defense could pursue an injunction based on its free speech arguments.

He concurred that the other claims, particularly those seeking monetary compensation, should be dismissed.

The decision rendered on Friday reaffirmed a ruling made in June 2021 by U.S. District Judge Susan Illston in San Francisco.

The case is identified as Children's Health Defense v Meta Platforms Inc, 9th U.S. Circuit Court of Appeals, No. 21-16210.
