Understanding the Felony Defense Under RCW 4.24.420
Washington law recognizes a legal principle often referred to as the felony defense. Under RCW 4.24.420, a defendant may avoid liability in certain personal injury or wrongful death lawsuits when the injured or deceased person was committing a felony that caused the injury or death.
The statute reflects a policy decision by the Washington legislature: individuals who are injured while committing a felony should not generally be able to recover damages when their criminal conduct caused the harm.
However, the law also contains important exceptions and procedural safeguards, particularly when the incident involves law enforcement activities.
How the Felony Defense Works in Washington
Under RCW 4.24.420, a defendant may assert a complete defense to liability if two elements are satisfied:
- The injured or deceased person was engaged in the commission of a felony at the time of the incident.
- The felony was a proximate cause of the injury or death.
If both conditions are proven, the statute provides a complete bar to recovery in a civil action for damages.
This means the defendant is not legally responsible for the injuries or death resulting from the event.
The Role of Proximate Cause
The statute requires more than just proof that a felony occurred. The felony must be a proximate cause of the injury or death.
In Washington law, proximate cause typically requires:
- Cause in fact (the injury would not have occurred without the conduct), and
- Legal causation (the harm is reasonably related to the conduct).
If the felony is unrelated to the injury, the defense may not apply.
Special Rules for Law Enforcement Incidents
Felony Defense Washington Law and Police Encounters
RCW 4.24.420 contains a special rule when the injury or death arises from law enforcement activities.
In these situations, the defense applies only if the finder of fact determines beyond a reasonable doubt that:
- The injured or deceased person was committing a felony, and
- The felony was a proximate cause of the injury or death.
This standard—beyond a reasonable doubt—is the highest evidentiary standard used in law. It is normally reserved for criminal trials.
By requiring this heightened level of proof, the statute creates additional protections in cases involving police use of force or other law enforcement actions.
Interaction With Federal Civil Rights Claims
RCW 4.24.420 specifically states that it does not affect actions brought under 42 U.S.C. § 1983.
Section 1983 allows individuals to file civil lawsuits when government officials violate constitutional rights.
Because federal law governs these claims, the Washington felony defense statute cannot eliminate or limit federal civil rights claims. Even if the defense might apply to a state-law wrongful death or personal injury claim, a federal constitutional claim may still proceed.
This distinction is especially important in cases involving alleged excessive force by police officers.
Why RCW 4.24.420 Matters in Civil Litigation
The felony defense has significant implications in Washington personal injury and wrongful death litigation.
Key effects of the statute include:
- Preventing recovery when injuries occur during criminal conduct
- Limiting liability in cases involving dangerous felonies
- Establishing a high evidentiary standard in police-related incidents
- Preserving federal civil rights claims under 42 U.S.C. § 1983
Because the defense can completely bar recovery, it often becomes a critical issue early in litigation.
Both plaintiffs and defendants must carefully evaluate:
- Whether a felony occurred
- Whether the felony was a proximate cause of the injury
- Whether the incident involved law enforcement activities
When Legal Guidance May Be Important
Cases involving injuries or deaths during alleged criminal conduct can raise complex legal questions. Determining whether RCW 4.24.420 applies often requires careful analysis of criminal conduct, causation, and the circumstances of the event.
An experienced Washington attorney can help evaluate potential claims or defenses and determine how the statute may affect a particular case.
