Washington Senate Bill 5870 — Establishing civil liability for suicide linked to the use of artificial intelligence systems

Status ● Introduced Effective N/A Passage Likelihood L

WHAT THIS BILL REGULATES · 4 REQUIREMENT TYPES

How Is This Bill Enforced

Enforcement Authority
Private right of action. No designated agency enforcer for compliance. A person who suffers injury in fact may bring a civil action. Section 7 creates a separate wrongful-death evidentiary presumption (prima facie evidence of wrongful act, neglect, or default) against owners of AI systems under chapter 4.20 RCW when a user's suicide is linked to AI system outputs.
Private Right of Action
Private right of action.
Penalties
Greater of actual damages or $1,000 per violation. Plaintiff may also recover injunctive relief and reasonable attorneys' fees and costs. In an action against a defendant who developed, modified, or used AI, it is not a defense that the AI autonomously caused the harm. Separately, under the wrongful-death chapter (RCW 4.20), prima facie evidence of wrongful death arises when suicide-related conditions are met.

Section 1 establishes the defined terms for the new chapter added to Title 19 RCW. The definitions closely mirror those in California SB 243. The companion chatbot definition is broad — covering any AI system with a natural language interface that provides adaptive, human-like responses and can sustain a relationship across multiple interactions — but includes three carve-outs for customer-service/productivity bots, video-game-limited bots, and stand-alone voice-assistant devices. The operator definition covers any person who makes a companion chatbot platform available to a user in Washington.

Section 2 imposes the bill's core operating obligations on operators of companion chatbot platforms. Subsection (1) requires AI identity disclosure when a reasonable person would be misled into believing they are interacting with a human — a conditional trigger tied to the reasonable-person standard. Subsection (2) establishes a continuous operating prerequisite: operators may not allow their companion chatbot to engage with users unless a protocol is in place to prevent the production of suicidal ideation, suicide, or self-harm content, including crisis referral notifications. The operator must also publish that protocol on its website.

Subsection (3) imposes heightened obligations when the operator knows the user is a minor: unconditional AI identity disclosure, a periodic take-a-break notification at least every three hours, and reasonable measures to prevent the chatbot from producing sexually explicit visual material or directly urging the minor to engage in sexually explicit conduct.

(1)(a)–(d) 9 For purposes of this chapter, it is prima facie evidence that the death of a person is caused by the wrongful act, neglect, or default of the owner of an artificial intelligence systemArtificial intelligence system"Artificial intelligence system" means an engineered or machine-based system that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs that can influence physical or virtual environments and that may operate with varying levels of autonomy.Sec. 7(2) if: (a) The person's cause of death is determined to be suicide; (b) The person provided inputs to the owner's artificial intelligence systemArtificial intelligence system"Artificial intelligence system" means an engineered or machine-based system that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs that can influence physical or virtual environments and that may operate with varying levels of autonomy.Sec. 7(2) related to suicide; (c) The owner's artificial intelligence systemArtificial intelligence system"Artificial intelligence system" means an engineered or machine-based system that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs that can influence physical or virtual environments and that may operate with varying levels of autonomy.Sec. 7(2) caused or aided the person's suicide by: (i) Providing instructions on how to attempt suicide; (ii) Encouraging the person to attempt suicide; or (iii) Failing to refer the person to the 988 national suicide prevention hotline or its successor; and (d) The owner of the artificial intelligence systemArtificial intelligence system"Artificial intelligence system" means an engineered or machine-based system that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs that can influence physical or virtual environments and that may operate with varying levels of autonomy.Sec. 7(2) knew or should have known that the artificial intelligence systemArtificial intelligence system"Artificial intelligence system" means an engineered or machine-based system that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs that can influence physical or virtual environments and that may operate with varying levels of autonomy.Sec. 7(2) could cause or aid a person to attempt suicide.

Section 7 adds a new section to Washington's wrongful-death statute (chapter 4.20 RCW) establishing a prima facie evidence standard. When a person's death is determined to be suicide and the person provided suicide-related inputs to an AI system, the death is prima facie evidence of wrongful act, neglect, or default by the AI system's owner if the system (1) provided instructions on how to attempt suicide, (2) encouraged the person to attempt suicide, or (3) failed to refer the person to the 988 National Suicide Prevention Hotline — and the owner knew or should have known the system could cause or aid suicide. This provision extends beyond companion chatbots to any artificial intelligence system as separately defined in subsection (2).
