Mutual combat is not legal in Washington in any meaningful sense. No state statute authorizes two people to agree to fight, and Washington courts have steadily narrowed the common-law idea that consent cancels out an assault. Police can arrest everyone involved in a street fight regardless of whether both sides agreed to it, and prosecutors can file charges whenever the injuries are serious enough.
Where the “Mutual Combat State” Idea Came From
The belief that Washington blesses consensual fighting traces largely to a November 2012 incident in Seattle. Ben Fodor, a self-styled superhero known as “Phoenix Jones,” approached a man on the street and asked, “Would you like to fight? Washington is a mutual-combat state.” The man agreed, they set ground rules, and Fodor knocked him out in 37 seconds while officers watched. No one was arrested. A Seattle police sergeant at the scene told reporters it was “not assault” because “these two guys squared up on each other.”
The same sergeant later walked that back, clarifying that “it’s actually not legal to fight on any city street or in any public place.” What happened that night was a judgment call by officers, not an application of settled law. The incident became viral folklore, and the folklore has outlived the correction.
What Washington Law Actually Says
Washington’s use-of-force statute, RCW 9A.16.020, spells out when force is lawful: performing a legal duty as a public officer, making a citizen’s arrest, self-defense, detaining a trespasser, and a few other narrow situations. Mutual combat is not on that list.1Washington State Legislature. RCW 9A.16.020 – Use of Force When Lawful No other section of the Revised Code of Washington carves out a mutual-combat exception to assault.
The theory supporting a consent defense comes from common law: assault requires an unwanted touching, so if both people agree, the touching isn’t unwanted. Washington’s appellate courts have accepted a sliver of that reasoning and rejected most of it.
How Washington Courts Treat Consent
Three appellate decisions set the pattern:
- In State v. Shelley (1997), a player in a pickup basketball game punched an opponent hard enough to break his jaw in three places. The court held that consent can apply during athletic contests, but only to injuries that are “reasonably foreseeable hazards” of the sport. An intentional punch during basketball is not one. The second-degree assault conviction stood.2FindLaw. State v. Shelley
- In State v. Hiott (1999), two people agreed to shoot BB guns at each other as a game. When one suffered a serious eye injury, the court rejected the consent defense on public-policy grounds.
- In State v. Weber (2007), the court held that consent is not a defense to second-degree assault in the context of a willing fight between inmates.
The Shelley court was explicit that “courts have declined to apply the defense” to things like “a school child’s consent to a fight” or “a gang member’s consent to a beating.”2FindLaw. State v. Shelley If a consensual fight causes real harm, the defense will almost certainly fail.
The Seattle Ordinance Everyone Cites
Seattle Municipal Code 12A.06.025, dating from 1973, is the ordinance most often pointed to as proof mutual combat is legal. It reportedly allows fist fights when both participants consent and there is no danger to bystanders or property. This is apparently what officers were relying on, or at least invoking, during the Phoenix Jones episode.
Two things matter about this ordinance. It is a city rule that applies only inside Seattle, and it does not override state assault law. If a consensual fight produces substantial bodily harm, the King County prosecutor can still charge assault under the RCW regardless of what the municipal code tolerates. The ordinance also does nothing to shield a participant from a civil lawsuit, or to protect bystanders and property owners from the fallout.
Other Washington Cities Criminalize It
Outside Seattle, some cities go the opposite direction. Tumwater’s municipal code makes it a misdemeanor to “engage in or provoke combat with another person upon the streets, walks, or other areas of the city open to the public, or upon unauthorized private areas.” The only carve-out is for “regularly scheduled and sanctioned sporting events such as boxing, wrestling, or the martial arts, where safety precautions are taken to reduce serious physical injury.”3Code Publishing Company. Tumwater Municipal Code 9.08.070 – Mutual Combat
A fight that Seattle officers might walk away from could produce a misdemeanor arrest two towns over. Assuming the Phoenix Jones framing applies statewide is a quick path to handcuffs.
When Consent Is Not a Defense at All
Several circumstances strip away any possibility of using consent or mutual combat as a shield.
Domestic Violence
If the people involved are current or former spouses, dating partners, cohabitants, or share a child, the encounter falls under Washington’s domestic violence framework in RCW Chapter 10.99. Mandatory arrest policies apply, and consent is treated as legally irrelevant. A fourth-degree assault that would ordinarily be a gross misdemeanor can be charged as a Class C felony if the person has two or more prior domestic violence convictions within ten years.4Washington State Legislature. RCW 9A.36.041 – Assault in the Fourth Degree
Serious Injuries
Under RCW 9A.04.110, “substantial bodily harm” includes temporary but substantial disfigurement, temporary loss of function in any body part, or a fracture. “Great bodily harm” means a probability of death, significant permanent disfigurement, or permanent loss of organ function.5Washington State Legislature. RCW 9A.04.110 – Definitions Once an injury hits either threshold, the consent defense collapses. A broken nose during a consensual fistfight is a fracture, and a fracture meets the statutory definition of substantial bodily harm.
Weapons
Any weapon raises the exposure immediately. Assault with a deadly weapon is second-degree assault, a Class B felony.6Washington State Legislature. RCW 9A.36.021 – Assault in the Second Degree If the weapon is used with intent to inflict great bodily harm, the charge becomes first-degree assault, a Class A felony.7Washington State Legislature. RCW 9A.36.011 – Assault in the First Degree A verbal agreement does not make a knife fight or a bat fight legal.
Minors
People under 18 cannot give legally valid consent to physical harm. A fight involving a minor is treated as an ordinary assault, and school-based incidents usually bring disciplinary consequences on top of criminal ones.
What Gets Charged If Things Go Wrong
When a consensual fight is prosecuted, the charge tracks the severity of the injuries and whether a weapon was used.
- Fourth-degree assault is the catch-all for assaults that do not rise to a higher degree. It is a gross misdemeanor carrying up to 364 days in county jail and a fine up to $5,000. This is the charge most often connected to mutual combat situations that do get prosecuted.8Washington State Legislature. RCW 9A.20.021 – Maximum Sentences
- Third-degree assault is a Class C felony that applies in specific contexts, including assault with criminal negligence using a weapon or causing bodily harm with substantial pain.9Washington State Legislature. RCW 9A.36.031 – Assault in the Third Degree
- Second-degree assault is a Class B felony and applies when a deadly weapon is used or when the assault recklessly inflicts substantial bodily harm.6Washington State Legislature. RCW 9A.36.021 – Assault in the Second Degree
- First-degree assault is a Class A felony for assaults committed with intent to inflict great bodily harm using a deadly weapon or force likely to cause death.7Washington State Legislature. RCW 9A.36.011 – Assault in the First Degree
The jump from misdemeanor to felony happens faster than most people expect. Someone falls, hits concrete, suffers a skull fracture, and the puncher is now facing a Class B felony no matter what the two of them agreed to a minute earlier.
Civil Lawsuits
Even if prosecutors pass on charges, the injured participant can sue for battery. Civil cases use a lower burden of proof than criminal ones, and damages for medical bills, lost wages, and pain are tied to actual harm, not to whether the fight was consensual.
A pre-fight waiver generally will not block that suit. Courts routinely refuse to enforce liability waivers for intentional physical harm on public-policy grounds. Letting people sign away the right to sue for being hurt would remove any reason to show restraint, and the analysis gets harder, not easier, when the activity is intentional striking rather than incidental contact in a recognized sport.
Firearm Consequences
A misdemeanor assault conviction can trigger a federal lifetime firearm prohibition if the fight involved someone in a domestic relationship. Federal law bars anyone convicted of a misdemeanor crime of domestic violence from possessing a firearm or ammunition. The bar applies when the convicted person was a current or former spouse, cohabitant, co-parent, or dating partner of the victim at the time of the offense.10Bureau of Alcohol, Tobacco, Firearms, and Explosives. Misdemeanor Crimes of Domestic Violence Prohibitions There is no exception for government employees, military personnel, or law enforcement officers. People who agree to “just a fight” with a partner or ex rarely think about losing their gun rights, but it is a common outcome.
The Legal Way to Fight in Washington
Washington regulates boxing, mixed martial arts, wrestling, and other combat sports under RCW Chapter 67.08. Fights held under that framework are lawful because they satisfy the conditions courts have identified for the consent defense to work: a recognized sport, safety precautions, medical personnel on hand, and rules limiting the kind of harm participants can inflict on each other.
The Tumwater ordinance captures the line precisely by criminalizing street fighting while exempting “regularly scheduled and sanctioned sporting events such as boxing, wrestling, or the martial arts, where safety precautions are taken to reduce serious physical injury.”3Code Publishing Company. Tumwater Municipal Code 9.08.070 – Mutual Combat Two people agreeing to fight in a parking lot do not turn that fight into a sanctioned event by writing down a few rules first. The sanctioned path exists, and it is the only one that reliably stays on the right side of Washington law.
