Firearms Regulations.  Firearms and other weapons are regulated under Washington law.  Among other restrictions, the state prohibits all persons from manufacturing, owning, buying, selling, loaning, furnishing, transporting, possessing, or controlling any machine gun, bump-fire stock, undetectable firearm, large capacity magazines, and certain other weapons, subject to various exceptions.

Washington does not specifically define and regulate a general class of weapons designated as assault weapons, but the state has established various restrictions on a group of weapons classified as semiautomatic assault rifles.  State law defines a semiautomatic assault rifle as any rifle which utilizes a portion of the energy of a firing cartridge to extract the fired cartridge case and chamber the next round, and which requires a separate pull of the trigger to fire each cartridge, but this definition excludes antique firearms, any firearm that has been made permanently inoperable, and any firearm that is manually operated by bolt, pump, lever, or slide action. 

Restrictions on semiautomatic assault rifles include:

• no dealer may deliver a semiautomatic assault rifle to the purchaser until:
  1. the purchaser provides proof they have completed a recognized firearm safety training program within the last five years;
  2. the dealer is notified by the chief of police or sheriff that the purchaser is eligible to possess a firearm and the purchase is approved; and
  3. ten business days have elapsed since the purchase application or, in the case of a transfer, ten business days have elapsed from the date a background check was initiated;
• the purchaser of a semiautomatic assault rifle must be personally known to the dealer or present clear evidence of their identity; and
• subject to various exceptions, a person under 21 years of age may not purchase a semiautomatic assault rifle, and no person may sell or transfer a semiautomatic assault rifle to a person under 21 years of age.

Federal law previously restricted certain semiautomatic assault weapons, subject to various exceptions and a sunset provision.  These federal restrictions expired in 2004.  Nine other states and the District of Columbia have enacted laws imposing various restrictions on assault weapons.

The Consumer Protection Act.  The Consumer Protection Act (CPA) prohibits unfair methods of competition, and unfair or deceptive acts or practices in trade or commerce.  If a person is injured in their business or property by a violation of the CPA, the person may bring a civil action to enjoin further violations and recover actual damages, costs, and reasonable attorney's fees.  Whenever the attorney general believes any person may have material or information relevant to an investigation into a violation of the CPA, the attorney general may issue a civil investigative demand requiring the person to produce the materials, answer interrogatories, or testify. The Attorney General may bring a legal action to enjoin violations of the CPA, obtain restitution, and seek civil penalties. 

The manufacture, importation, distribution, sale, or offer for sale of any assault weapon is prohibited.  The term "assault weapon" is defined to include various kinds of firearms, including:

• specific firearm models identified in the bill;
• semiautomatic rifles with an overall length of less than 30 inches;
• semiautomatic centerfire rifles that have the capacity to accept a detachable magazine and have one or more additional features listed in the bill; 
• semiautomatic centerfire rifles with a fixed magazine with the capacity to accept more than ten rounds;
• semiautomatic pistols that have the capacity to accept a detachable magazine and have one or more additional features listed in the bill;
• semiautomatic shotguns that have one or more additional features listed in the bill; and
• conversion kits and parts that can be used to assemble an assault weapon or convert a firearm into an assault weapon, if the parts are in the possession of or under the control of the same person.

The term assault weapon excludes antique firearms, firearms that have been made permanently inoperable, and firearms that are manually operated by bolt, pump, lever, or slide action. 

The restrictions on assault weapons are subject to several exceptions:

• licensed firearms manufacturers are authorized to manufacture, import, distribute, offer for sale, and sell assault weapons for the purpose of sale to the armed forces of the Untied States or Washington, or to any law enforcement agencies for law enforcement purposes, or to a person who does not reside in Washington;
• licensed firearms dealers are authorized to import, distribute, offer for sale, and sell assault weapons for the purpose of sale to the armed forces of the United States or Washington, or to law enforcement agencies in Washington for law enforcement purposes;
• licensed firearms dealers are authorized to distribute, offer for sale, and sell assault weapons that were acquired from an individual legally authorized to possess or transfer the weapon, for the purpose of selling or transferring the weapon to a person who does not reside in Washington;
• the purpose of this exception is to allow individuals who no longer wish to own an assault weapon to sell their assault weapon and the exception is not intended to allow Washington dealers to purchase assault weapons wholesale for the purpose of selling a stock or inventory of assault weapons online or in person to nonresidents;
• firearms dealers may sell or transfer their existing stock of assault weapons that were acquired prior to January 1, 2023, to outside of the state for the limited period of 90 days after the effective date;
• persons on active military duty receiving orders to move to Washington State, or military retirees moving to Washington State; and 
• any person may acquire possession of an assault weapon by operation of law upon the death of the weapon's former owner, if that former owner was in legal possession of the weapon and the person who acquires possession can establish such provenance.

A violation of these restrictions is classified as a gross misdemeanor. 

A violation is classified as a matter vitally affecting the public interest, not reasonable in relation to the development and preservation of business, and an unfair or deceptive act in trade or commerce and an unfair method of competition for the purpose of applying the CPA. 

If the Attorney General issues a civil investigative demand regarding a potential violation of these restrictions, the recipient of the demand may file in Superior Court a petition to extend the time to respond, or modify or set aside the demand for good cause.  The Attorney General is prohibited from sharing any materials or information obtained through a civil investigative demand with any law enforcement agency conducting a criminal investigation, unless required to do so pursuant to a search warrant. 

The committee recommended a different version of the bill than what was heard.  PRO:  This bill has been introduced in some form for the last 7 years since there was a shooting and a young man who purchased an assault weapon killed three people and wounded others.  We want to stop the next mass shooting.  The list of assault weapons is very specific but we are also addressing general features so that if new weapons come out they will also be covered.  This will save lives.  Assault weapons are designed for the sole purpose of maximizing killing.  Assault weapons are 11 times more likely to be used in mass shootings and seven times more likely to be used to kill a law enforcement officer.

This bill is on sound constitutional footing and similar laws have been upheld across the country. The Supreme Court has reiterated that firearm rights are not unlimited and the Second Amendment does not protect a right to keep and bear any weapon whatsoever.

CON:  This bill bans the most commonly owned and lawfully possessed firearms, including some pistols and shotguns.  "Assault weapon" is a manufactured term and fear mongering.  The weapons targeted by this bill are the most popular self-defense weapons in America, contrary to the Legislature's finding that they are not suitable for self defense. It is beyond dispute that a statistically significant number of citizens possess semiautomatic rifles for self-defense.  Similar bans have not been upheld under the Bruen test and there are 20 active court cases challenging similar bans across the country. This law will be found unconstitutional, but it could take the courts years to resolve.
