Misprision of Treason Under California Penal Code 38

Posted by Bulldog Law | Jul 15, 2025

Misprision of Treason Under California Penal Code 38

California Penal Code Section 38 makes it a felony offense to know about treason and fail to report it. While the charge of misprision of treason is rare, it carries serious legal consequences. This law stems from centuries-old principles of civic duty and still holds power today, especially in the context of state security and domestic threats. If you are facing this charge, understanding its legal foundations and potential defenses is critical.

What Is Misprision of Treason?

Under California law, misprision of treason occurs when someone knows that an act of treason is being planned or has occurred, and willfully conceals this knowledge without having participated in or assented to the treasonous act. This statute carves out a unique space in criminal law where silence can become criminal.

Elements the Prosecution Must Prove

To secure a conviction, the prosecution must prove three essential elements beyond a reasonable doubt:

  • Actual knowledge of treason – The defendant must have had specific and credible awareness of the treasonous act or plan.
  • Concealment of that knowledge – The person must have made a conscious decision to withhold this information from authorities.
  • No participation or assent – The individual must not have directly or indirectly aided the treason.

Each of these elements can present significant opportunities for defense attorneys to challenge the credibility and clarity of the prosecution's evidence.

What Constitutes Treason in California?

Under California law, treason includes levying war against the state or giving aid and comfort to its enemies. This could involve organized rebellion, assisting foreign governments against California, or supporting terrorism aimed at the state government.

The Historical Foundation of the Law

Misprision laws trace back to English common law, where failing to report treason was seen as a betrayal of the Crown. California retained this notion in its early criminal code, signaling that threats against the state must be met not only with punishment for actors but also for those who stay silent.

Penalties for Misprision of Treason

A conviction under Penal Code Section 38 is treated as a felony and may result in sentencing under Section 1170(h), which includes:

  • State prison time (often ranging from 16 months to 3 years)
  • Substantial fines
  • Probation under strict supervision
  • Possible restitution or civil damages depending on harm caused

Collateral Consequences

Beyond criminal penalties, a conviction may have long-lasting effects, including:

  • Loss of professional licenses
  • Denial of security clearance
  • Immigration consequences for non-citizens
  • Ineligibility for public office or government employment

Defense Strategies Against Misprision Charges

Because the law is specific and rarely prosecuted, effective defense depends on detailed legal analysis and constitutional protections. Common strategies include:

Challenging Knowledge of Treason

The defense may argue that the accused had only vague or unreliable information that did not rise to the legal standard of “knowledge.” Proving a lack of concrete awareness can help defeat this element.

Demonstrating Lack of Concealment

Evidence that the defendant informed someone, even informally, or had legitimate fear for their safety in reporting, may counter claims of concealment.

Intent and Constitutional Protections

Courts generally require intentional concealment. Passive silence, especially without clarity on legal duty, may not be sufficient for conviction. Furthermore, First Amendment and due process concerns may apply. These arguments may resemble those used when raising mental health defense in criminal cases under California Penal Code 25, particularly when concealment is connected to impaired decision-making.

The Role of Jurisdiction and Related Offenses

Misprision of treason applies strictly to offenses against the State of California. When the alleged treason involves federal matters, such as espionage or aiding enemies of the United States, then federal treason or related charges may apply. In such cases, it's essential to distinguish between state and federal jurisdiction to assess whether the misprision charge is even valid.

It's also worth noting that misprision differs from being an accessory after the fact under California Penal Code 32. The latter involves active aid after the commission of a felony, while misprision involves no participation but criminalized silence.

Is Silence Always Criminal?

Generally, California law does not obligate private citizens to report crimes. Misprision of treason is one of the few exceptions. This raises significant policy and constitutional questions, such as whether the government can or should punish people simply for remaining silent, especially when speech or disclosure could endanger them or others.

How Violent Felony Designations Might Apply

While misprision of treason is not currently listed among the violent felony charges in California under Penal Code 667.5 PC, its serious implications could be considered aggravating factors at sentencing. A conviction might influence parole eligibility, probation terms, or other collateral consequences depending on the case facts.
