Mind Your Own Business Act of 2023

S 189, the "Mind Your Own Business Act of 2023," creates new procedural rules for shareholder lawsuits against large corporations ($20B+ market cap or $5B+ revenue) alleging actions related to social or political issues. It defines "covered claims" as lawsuits where corporations allegedly used resources for: opposing state laws on elections/abortion/religious freedom, boycotting industries (e.g., firearms, border security), promoting "covered divisive concepts" (like race/sex stereotyping), or coordinating with political actors. The bill shifts the burden of proof to corporate defendants, mandates treble damages or double director compensation if plaintiffs win, requires defendants to pay plaintiffs' legal fees, and prohibits indemnification for such claims. This directly affects large corporations and shareholders pursuing these specific types of lawsuits under securities law.
