Possession of a Dangerous Weapon: California Penal Code 12020(a)

Although California reorganized its weapons statutes under the Dangerous Weapons Control Law in 2012 (moving former Penal Code 12020 provisions into PC 16590 and related sections), legal practitioners and courts still frequently reference former California Penal Code 12020(a).

This law criminalizes manufacturing, importing, selling, offering, or possessing specifically prohibited weapons and concealed dangerous items in California.

Statutory Language

Under former California Penal Code 12020(a), any person in California who manufactures or causes to be manufactured, imports into the state, keeps for sale, or offers or exposes for sale, or who gives, lends, or possesses any cane gun or wallet gun, any plastic firearm, any firearm which is not immediately recognizable as a firearm, any camouflaged firearm container, any ammunition which contains or carries an explosive agent, any dirk or dagger, or any instrument or weapon of the kind commonly known as a blackjack, slungshot, billy, sandclub, sap, or metal knuckles, is guilty of a crime.

Key Statutory Definitions

Understanding the legal scope of PC 12020(a) requires precise definitions of statutory terminology:

• Generally Prohibited Weapons: Specific weapons explicitly banned by California statute due to their dangerous design or concealed nature. Common examples include brass knuckles, concealed fixed-blade knives, ballistic knives, short-barreled shotguns, and zip guns.

• Dirk or Dagger: Under California law, a knife or other instrument with or without a handguard that is capable of ready use as a stabbing weapon that may cause great bodily injury or death.

• Actual Possession: Physical custody or direct control over a prohibited weapon (e.g., carrying metal knuckles in a jacket pocket).

• Constructive Possession: Exercising power and intent to control a prohibited item, even if not in physical contact (e.g., storing a sap inside a vehicle's locked glove compartment).

What Must Be Proven to Convict

To secure a conviction for possessing a prohibited or dangerous weapon under PC 12020(a) standards, a prosecutor must establish the following elements beyond a reasonable doubt:

1. Possession or Action: The defendant manufactured, imported, offered for sale, gave, lent, or possessed a specifically prohibited weapon or instrument listed under the statute.

2. Knowledge of Item's Character: The defendant knew they possessed or controlled the item and knew that the item had the characteristics of a prohibited weapon (though they do not need to know the specific code section or that it was illegal).

3. Weapon Classification: The item in question physically meets the legal definition of a banned weapon (e.g., qualifying as a dirk or dagger or metal knuckles under California statutory criteria).

Penalties and Sentencing Options

Violations under former PC 12020(a) (and current successor sections under PC 16590) are typically classified as wobblers, meaning prosecutors can charge the offense as either a misdemeanor or a felony based on criminal history and case severity.

Offense Classification	Incarceration + Fine	Probation & Additional Terms
Misdemeanor	Up to 1 year in county jail. Up to $1,000	Summary probation; mandatory weapon forfeiture
Felony	16 months, 2 years, or 3 years in county jail. Up to $10,000	Formal probation; permanent loss of firearm rights

Practical Examples

• Example 1 (Prohibited Concealed Blade): A driver carries a fixed-blade hunting knife concealed inside their waistband during a traffic stop. Because the knife is hidden on the person and can be used immediately as a stabbing tool, it meets the definition of a concealed dirk or dagger.

• Example 2 (Constructive Possession): Officers search a backpack placed in a car's backseat and locate a set of custom metal knuckles belonging to the rear passenger. The passenger exercises constructive possession over a banned instrument.

• Example 3 (Lack of Knowledge Defense): An individual borrows a friend's gym bag without knowing a pair of brass knuckles is hidden inside a zippered side pocket. Because the individual did not know the item was there, they lacked criminal intent.

Legal Defense Strategies

Criminal defense attorneys utilize several primary legal strategies to contest PC 12020(a) weapon allegations:

1. Lack of Knowledge or Awareness: Showing that the defendant was unaware the weapon was present or did not know the item had characteristics that made it a prohibited weapon.

2. Item Does Not Meet Statutory Definition: Arguing that the confiscated object does not legally qualify as a prohibited item (e.g., a folding pocket knife carried in a closed position that does not qualify as a fixed dirk or dagger).

3. Unlawful Search and Seizure: Establishing that law enforcement discovered the weapon through an illegal traffic stop, warrantless vehicle search, or coercive frisk lacking reasonable suspicion, leading to evidence suppression under Penal Code 1538.5.

4. Temporary Possession for Disposal: Proving the defendant briefly possessed the prohibited item solely to abandon, destroy, or turn it over to law enforcement.

Related California Laws

Understanding related offenses is crucial because prosecutors often file alternative or additional charges when an individual is arrested with a dangerous weapon or firearm.

• Penal Code 16590 (California's Generally Prohibited Weapons Law): The modern statutory framework containing the consolidated list of prohibited weapons previously prosecuted under former PC 12020(a).

• Penal Code 25400 (Carrying a Concealed Firearm): Prohibits carrying a concealed handgun on your person or within a motor vehicle without a valid permit.

• Penal Code 25850 (Carrying a Loaded Firearm in Public): Makes it unlawful to carry a loaded firearm in a public place or inside a vehicle on a public street.

• Penal Code 21310 (Carrying a Concealed Dirk or Dagger): Prohibits carrying a concealed stabbing instrument, carrying forward specific knife bans from PC 12020.

• Penal Code 29800 (Felon in Possession of a Firearm): Bans individuals with prior felony convictions from owning, purchasing, or possessing any firearm.

Frequently Asked Questions (FAQs)

Is PC 12020 still active in California law?

The provisions of former California Penal Code 12020 were reorganized in 2012 into separate sections within the California Penal Code (primarily starting at PC 16590 for generally prohibited weapons). However, the legal standards, definition of banned items, and penalties remain fundamentally the same under current law.

Can you carry a concealed pocket knife in California?

Yes, provided the pocket knife is in a folded or closed position and is not an illegal switchblade (having a blade two inches or longer that opens automatically). A folded pocket knife is generally not considered a concealed dirk or dagger unless it is locked in an open position.

What is the difference between actual and constructive possession?

Actual possession means you have direct physical control over the weapon, such as holding it or carrying it in your pocket. Constructive possession means you have control over the location where the weapon is stored, such as your vehicle trunk or personal storage locker.

Are brass knuckles completely illegal in California?

Yes. Metal knuckles (brass knuckles) fall under California's list of generally prohibited weapons. Manufacturing, selling, buying, or possessing them is illegal, whether they are displayed publicly or kept in private.

Can a PC 12020 weapon conviction be reduced to a misdemeanor?

Yes. Because these weapon violations are wobblers, an experienced defense attorney can petition the court to reduce a felony conviction to a misdemeanor upon successful completion of probation or during initial sentencing, provided no severe aggravating factors exist.
