The Ninth Circuit Court of Appeals has upheld a preliminary injunction that prevents California from enforcing a law that restricts employer communications about political and religious matters. This ruling affects various business associations, including the California Chamber of Commerce, the California Restaurant Association, and the Western Growers Association, which argued that the law violates their First Amendment rights. The decision is significant as it highlights the balance between employee rights and employer speech in the workplace.

The case, California Chamber of Commerce v. Bonta, No. 25-6874, originated when the aforementioned industry groups filed a lawsuit against California officials, including Attorney General Rob Bonta and Labor Commissioner Lilia Garcia-Brower. They sought to block the enforcement of California Senate Bill (SB) 399, which prohibits employers from subjecting employees to adverse actions if they choose not to attend employer-sponsored meetings discussing political or religious opinions. The industry groups contend that this law infringes upon their rights to free speech and is preempted by federal labor law.

The dispute arose after California passed SB 399, which took effect on January 1, 2025. The California Legislature expressed concern that employees might feel pressured to adopt their employers' views on political or religious matters during mandatory meetings. The law aims to protect employees from potential retaliation for opting out of these discussions. However, the industry groups argue that the law effectively silences employer speech, particularly in contexts where they wish to communicate their opinions on relevant issues.

The Ninth Circuit's ruling, delivered on October 29, 2026, affirmed the district court's decision to grant a preliminary injunction against the enforcement of SB 399. The court found that the Western Growers Association established standing to challenge the law, as some of its members hold meetings to discuss political matters and would continue to do so if the law were not in effect. The court noted, "The industry groups are likely to succeed on the merits of their First Amendment claim," indicating that the law likely violates their free speech rights.

The panel of judges, including Richard A. Paez, Richard C. Tallman, and Mark J. Bennett, emphasized that the law is content-based and speaker-based, as it applies only when employers discuss specific topics. The court applied strict scrutiny, a high level of judicial review that requires the government to prove that a law serves a compelling state interest and is narrowly tailored to achieve that interest. The court rejected California's argument that the law serves to protect a "captive audience" of employees, stating that such a justification does not hold in a non-governmental setting.

The court's opinion highlighted that the First Amendment applies to laws that regulate conduct with a significant expressive element. It concluded that SB 399's restrictions on employer speech are unconstitutional, as they single out political and religious speech for regulation. The court stated, "Because employers are forbidden from taking adverse action only if they communicate certain messages at the underlying meeting, the law inevitably singles out employers based on their expressive activity." This ruling reinforces the importance of free speech in the workplace and sets a precedent for future cases involving employer communications.

The impact of this ruling is significant for employers and industry groups across California. It protects their ability to discuss political and religious matters without fear of legal repercussions. The decision also serves as a reminder of the ongoing tension between employee protections and employer rights to free speech. The ruling may influence similar legislation in other states and could lead to further legal challenges against laws perceived to infringe on free speech rights.

As for the next steps, California could choose to appeal the Ninth Circuit's decision to the U.S. Supreme Court. However, details regarding any potential appeal or related cases were not available in the court filing. The outcome of this case may prompt lawmakers to reconsider the implications of SB 399 and its alignment with constitutional rights.
