The bill introduces a new section to chapter 42.04 of the Revised Code of Washington (RCW) that explicitly prohibits governmental entities from granting or recognizing legal personhood to various non-human entities. This includes artificial intelligence, inanimate objects, bodies of water, land, real property, atmospheric gases, astronomical objects, weather, plants, nonhuman animals, and any other members of a taxonomic domain that are not classified as natural persons.

Additionally, the bill defines key terms related to the legislation, such as "body of water," "governmental entity," "land," "legal personhood," and "real property." These definitions clarify the scope of the bill and ensure that the prohibition on legal personhood is clearly understood within the context of Washington state law.
