California Court Halts Enforcement of Senate Bill 399

Gavel in court symbolizing legal issues around Senate Bill 399.

California, October 4, 2025

News Summary

A federal court has issued a preliminary injunction against California’s Senate Bill 399, which aimed to restrict employer communications on political and religious matters. The ruling supports employers’ First Amendment rights and maintains that the law risks infringing upon federal labor law protections. This decision allows businesses to engage in conversations regarding essential workplace issues without fear of legal repercussions. The ruling has received backing from small business advocates, emphasizing the need for free enterprise communication.

California is at the center of a legal battle following a preliminary injunction issued by U.S. District Judge Daniel Calabretta against Senate Bill 399 (SB 399), a law aimed at curbing employer communications on religious and political issues. The ruling temporarily halts the enforcement of SB 399, which was passed in 2024 and took effect in 2025, pending further litigation.

The court found that SB 399 interferes with employers’ rights under the National Labor Relations Act (NLRA), asserting that it preempts the state law. This judicial decision underscores the First Amendment rights of employers, particularly their freedom to communicate within their businesses without state-imposed restrictions.

John Kabateck, the California state director for the National Federation of Independent Business (NFIB), expressed strong support for the ruling, highlighting its importance for small business owners’ rights to free speech. The temporary injunction allows businesses to continue discussing significant workplace matters without fear of legal repercussions stemming from SB 399.

SB 399 faced considerable criticism from the California Chamber of Commerce, which labeled the bill a “Job Killer” during its introduction in the 2024 legislative session. The plaintiffs, including the California Chamber of Commerce and the California Restaurant Association, initiated a federal lawsuit last December challenging the constitutionality of SB 399. They argue that the law infringes on employer free speech rights and introduces legal liabilities for necessary communications regarding pivotal issues at work.

The law specifically aimed to ban employers from mandating attendance at meetings focused on political or religious topics, including those related to unionization. This legislation has been challenged not only on its own merits but also in conjunction with Assembly Bill 288, which grants the state Public Employment Relations Board (PERS) enforcement powers over collective bargaining rights in scenarios where the NLRA does not act promptly. The plaintiffs assert that such state-level interference improperly encroaches upon federal authority as outlined in existing labor laws.

This legal dispute unfolds against the backdrop of shifting interpretations of labor laws and governance, particularly under the current federal administration, which has affected the NLRA’s application in recent years. The injunction issued by Judge Calabretta will remain in place while litigation continues in the district court, with the potential for a permanent injunction based on the final ruling.

The NFIB emphasized that it is critical for employers to maintain the ability to communicate transparently with employees, free from state limitations that could jeopardize business operations and workplace dynamics.
