California Penal Code Section 128: Defending Against the Ultimate Perjury Penalty

Posted by Bulldog Law | Feb 06, 2026

California Penal Code Section 128 represents the most severe perjury statute in California law, imposing the ultimate penalties death or life imprisonment without parole for those who through willful perjury or subornation of perjury procure the conviction and execution of an innocent person.

This extraordinarily serious charge reflects society's recognition that false testimony leading to wrongful execution constitutes one of the gravest offenses possible. 

Understanding this statute's elements, defenses, and the complex legal framework surrounding capital punishment becomes essential for anyone facing these ultimate charges.

Understanding California Penal Code Section 128

California Penal Code Section 128 criminalizes the act of procuring an innocent person's conviction and execution through willful perjury or subornation of perjury. The statute establishes that such conduct is punishable by death or life imprisonment without the possibility of parole, with penalty determination governed by Penal Code Sections 190.3 and 190.4.

This law recognizes that perjury resulting in wrongful execution represents an irreversible miscarriage of justice that demands the most severe punishment available under California law. The statute's placement of this offense among capital crimes reflects the legislature's view that causing innocent deaths through false testimony warrants punishment equivalent to murder.

The law applies to both direct perjury (personally lying under oath) and subornation of perjury (procuring others to commit perjury). This broad coverage ensures that all participants in schemes that result in wrongful executions through false testimony face maximum penalties.

Essential Elements Prosecutors Must Prove

Section 128 prosecutions require proof of multiple complex elements, each presenting significant challenges for prosecutors and opportunities for defense attorneys. Understanding these requirements is crucial for developing effective defense strategies.

Willful Perjury or Subornation

Prosecutors must establish that defendants committed willful perjury or subornation of perjury. This requires proof beyond a reasonable doubt that defendants knowingly made false statements under oath or knowingly procured others to do so, with specific intent to deceive.

The willfulness requirement means that innocent mistakes, memory lapses, or inadvertent inaccuracies cannot support Section 128 charges. Defense attorneys should investigate whether defendants genuinely believed their statements were true or lacked the specific intent required for willful perjury.

Causation Between Perjury and Conviction

The prosecution must prove that the perjury actually procured the innocent person's conviction. This causation element requires evidence showing that false testimony was instrumental in securing the conviction, rather than merely being present during the proceedings.

Defense attorneys should examine whether other evidence would have supported conviction even without the allegedly false testimony. If independent evidence was sufficient for conviction, this may undermine the causation element required for Section 128 charges.

Innocence of the Executed Person

Prosecutors must establish that the executed person was actually innocent of the crime for which they were convicted and executed. This requirement presents unique evidentiary challenges, as it essentially requires retrying the underlying case to prove innocence.

This element creates significant defense opportunities, as proving innocence beyond a reasonable doubt can be extremely difficult, particularly in cases where the executed person was convicted based on substantial evidence beyond the allegedly false testimony.

Actual Execution Requirement

Section 128 specifically requires that the innocent person was actually executed, not merely sentenced to death. This requirement means that cases where death sentences were overturned, commuted, or not carried out cannot support Section 128 prosecutions.

The Capital Punishment Framework

Section 128's reference to Penal Code Sections 190.3 and 190.4 incorporates California's complex capital punishment procedures into perjury prosecutions. Understanding this framework is essential for defense attorneys handling these cases.

Penalty Phase Proceedings

Section 128 cases that result in conviction trigger penalty phase proceedings similar to those in murder cases. During this phase, juries must consider aggravating and mitigating factors specified in Section 190.3 to determine whether defendants should receive death sentences or life imprisonment without parole.

Defense attorneys must prepare comprehensive mitigation cases addressing defendants' backgrounds, mental health, family circumstances, and other factors that might persuade juries to impose life sentences rather than death. This requires extensive investigation and presentation of evidence about defendants' lives and circumstances.

Aggravating and Mitigating Factors

Section 190.3 establishes specific factors that juries must consider when determining appropriate penalties in capital cases. These include the circumstances of the crime, defendants' criminal history, the impact on victims' families, and various mitigating factors related to defendants' backgrounds and mental state.

Defense attorneys should thoroughly investigate and present mitigating evidence while challenging the prosecution's presentation of aggravating factors. The quality of mitigation presentation often determines whether defendants receive death sentences or life imprisonment.

Unique Defense Challenges in Section 128 Cases

Section 128 prosecutions present extraordinary defense challenges that distinguish them from other criminal cases. These challenges require specialized expertise and comprehensive preparation.

Proving Innocence of the Deceased

Unlike typical criminal cases where defendants are presumed innocent, Section 128 prosecutions require proving that someone else (the executed person) was innocent. This reversal of typical burden-of-proof concepts creates unique strategic challenges.

Defense attorneys may need to conduct parallel investigations into the underlying case that resulted in the wrongful conviction and execution. This might involve reinvestigating decades-old cases, locating witnesses, and challenging evidence that was accepted in previous proceedings.

Temporal and Evidentiary Complications

Section 128 cases often involve events that occurred many years earlier, creating significant evidentiary challenges. Witnesses may have died, memories may have faded, and physical evidence may have been lost or destroyed.

Defense attorneys must work with limited and potentially compromised evidence while trying to reconstruct events that may have occurred decades ago. This requires creative investigation techniques and careful evaluation of available evidence.

Complex Causation Analysis

Proving that perjury "procured" conviction and execution requires sophisticated causation analysis that considers all evidence presented in the underlying case. Defense attorneys must evaluate whether false testimony was truly instrumental in the conviction or whether other evidence would have been sufficient.

This analysis often requires expert testimony about trial strategy, jury decision-making, and the relative importance of different types of evidence in capital cases.

Constitutional and Procedural Defenses

Section 128 prosecutions raise numerous constitutional issues that defense attorneys should explore, particularly given the capital nature of these charges.

Due Process Challenges

The extraordinary penalties associated with Section 128 may raise due process concerns, particularly regarding the burden of proving innocence of deceased persons and the complex causation requirements. Defense attorneys should examine whether fundamental fairness principles are satisfied in specific cases.

Double Jeopardy Considerations

In some cases, Section 128 prosecutions might raise double jeopardy issues if defendants were previously prosecuted for underlying perjury offenses. Defense attorneys should analyze whether multiple prosecutions for related conduct violate constitutional protections.

Statute of Limitations Issues

Given the temporal distance between underlying perjury and Section 128 prosecutions, statute of limitations defenses may be available depending on when the wrongful execution was discovered and when charges were filed.

The Subornation of Perjury Element

Section 128's inclusion of subornation of perjury significantly broadens potential liability beyond those who personally testified falsely. Understanding this element is crucial for defending against charges based on procuring others' false testimony.

Proof Requirements for Subornation

Subornation of perjury requires proof that defendants knowingly procured others to commit perjury. This involves showing both that defendants knew the testimony would be false and that they took active steps to encourage or facilitate the false testimony.

Defense attorneys should examine whether defendants actually knew the testimony would be false or whether they reasonably believed the witnesses would testify truthfully. Evidence of good faith reliance on witnesses' representations may support defenses against subornation charges.

Distinguishing Legitimate Witness Preparation

The line between legitimate witness preparation and subornation of perjury can be unclear, particularly in complex cases involving extensive witness preparation. Defense attorneys should examine whether defendants' conduct constituted proper case preparation or crossed into procuring false testimony.

Mitigation Strategy in Capital Perjury Cases

When Section 128 convictions appear likely, defense strategy must focus heavily on penalty phase mitigation to avoid death sentences. This requires comprehensive investigation and presentation of defendants' backgrounds and circumstances.

Mental Health and Psychological Factors

Mental health evidence often proves crucial in capital penalty phases. Defense attorneys should investigate whether defendants suffered from mental illness, cognitive impairments, or other psychological factors that might explain their conduct and support life sentences.

Family and Social History

Comprehensive social history investigation can reveal mitigating factors such as childhood abuse, traumatic experiences, or other circumstances that might influence jury sentencing decisions. These investigations require extensive interviews with family members, friends, and others familiar with defendants' backgrounds.

The Rarity and Complexity of Section 128 Prosecutions

Section 128 prosecutions are extraordinarily rare, reflecting both the specific requirements for these charges and the difficulty of proving all necessary elements. This rarity means that few attorneys have experience with these cases, making specialized expertise crucial.

Investigative Resource Requirements

Section 128 cases require massive investigative resources to examine both the underlying wrongful conviction case and the circumstances surrounding the alleged perjury. Defense teams must be prepared for lengthy, expensive investigations involving multiple experts and extensive document review.

Coordination with Innocence Projects

Many Section 128 cases arise from work by innocence projects or similar organizations that have established wrongful convictions. Defense attorneys should coordinate with these groups to access their research and expertise about the underlying cases.

Ethical Considerations in Section 128 Defense

The gravity of Section 128 charges creates unique ethical obligations for defense attorneys, who must provide zealous representation while dealing with cases involving tragic miscarriages of justice.

Balancing Multiple Interests

Defense attorneys must balance their obligations to their clients against broader interests in justice and truth. These cases often involve acknowledging that terrible injustices occurred while still providing vigorous defense representation.

For anyone facing charges under California Penal Code Section 128, immediate consultation with attorneys experienced in capital defense is absolutely essential. These cases require specialized expertise, substantial resources, and comprehensive preparation that only qualified capital defense attorneys can provide.
