California Penal Code Section 940: Grand Jury Voting Requirements for Criminal Defense

Posted by Bulldog Law | Feb 04, 2026

Understanding Grand Jury Indictment Standards in California

California Penal Code Section 940 establishes specific voting requirements for grand jury indictments, creating different thresholds based on grand jury size while ensuring that indictments receive adequate deliberation and support before formal charges are filed.

From a defense attorney's perspective, understanding these voting requirements becomes crucial for challenging defective indictments and ensuring that prosecution decisions meet constitutional and statutory standards for probable cause determinations.

Grand Jury Size and Voting Thresholds

Twenty Three Member Grand Juries

In counties where grand juries consist of 23 members as prescribed by Section 888.2, at least 14 grand jurors must concur before an indictment can be found. This requirement means that a substantial majority of grand jurors must agree that probable cause exists to believe the defendant committed the charged offenses.

The 14 vote requirement in 23 member grand juries creates a threshold of approximately 61% agreement, ensuring that indictments receive support from a clear majority rather than a bare plurality of grand jurors who participate in deliberations.

Defense attorneys should verify that indictments from 23 member grand juries actually received the required 14 votes, as defective voting procedures can provide grounds for challenging indictment validity and seeking case dismissal.

Eleven Member Grand Juries

Counties utilizing 11 member grand juries must obtain concurrence from at least eight grand jurors before finding an indictment. This requirement maintains the same approximate percentage threshold as larger grand juries while accommodating the practical realities of smaller grand jury panels.

The eight vote requirement in 11 member grand juries represents approximately 73% agreement, actually creating a higher percentage threshold than larger grand juries while reflecting the different dynamics of smaller deliberative bodies.

Defense strategies should examine grand jury composition and voting records to ensure that smaller grand juries followed proper procedures and obtained adequate support before issuing indictments.

Standard Twelve Vote Requirement

All other counties not specifically covered by the 23 member or 11 member provisions must obtain concurrence from at least 12 grand jurors before finding indictments. This default standard applies to various grand jury sizes while maintaining consistent threshold requirements.

The 12 vote standard ensures adequate deliberation and support for indictments regardless of specific grand jury composition, creating uniform requirements that apply across most California counties.

Understanding which voting standard applies in specific counties helps defense attorneys evaluate indictment validity while identifying potential procedural challenges to prosecution charging decisions.

Procedural Requirements and Documentation

True Bill Endorsement

Section 940 requires that valid indictments be endorsed "A true bill" to indicate that proper voting procedures were followed and adequate grand juror support was obtained. This endorsement serves as formal certification that statutory requirements were met.

The true bill endorsement requirement creates documentary evidence of compliance with voting thresholds while providing defense attorneys with verification that proper procedures were followed during grand jury deliberations.

Absence of proper endorsement or defective endorsement procedures may provide grounds for challenging indictment validity and seeking dismissal of charges based on procedural violations.

Foreman Signature Requirements

Valid indictments must include signatures from grand jury forepersons, creating additional authentication requirements that help ensure proper grand jury procedures were followed throughout the indictment process.

Foreman signature requirements provide verification of grand jury deliberations while creating accountability mechanisms for ensuring that voting thresholds and procedural requirements receive proper attention.

Defense attorneys should examine foreman signatures and related documentation to verify that indictments comply with all statutory authentication requirements and procedural safeguards.

Constitutional and Legal Challenges

Due Process and Probable Cause Standards

Grand jury indictments must meet constitutional probable cause requirements regardless of the specific voting thresholds established by state law. The statutory voting requirements supplement rather than replace constitutional standards for valid indictments.

Due process challenges to grand jury indictments may focus on whether adequate evidence supported probable cause determinations or whether procedural violations compromised the reliability of grand jury deliberations.

Defense strategies should examine both statutory compliance and constitutional adequacy when evaluating potential challenges to grand jury indictments and charging decisions.

Equal Protection and Geographic Disparities

The different voting thresholds for different counties may raise equal protection questions about whether defendants receive equivalent treatment regardless of where their cases are prosecuted by grand jury action.

However, rational basis analysis likely supports the statutory scheme because different voting thresholds accommodate practical differences in grand jury size while maintaining equivalent percentage requirements across jurisdictions.

Constitutional challenges based on geographic disparities would need to demonstrate that voting threshold differences create unfair advantages or disadvantages that violate equal protection principles.

Strategic Defense Applications

Challenging Defective Indictments

When grand juries fail to comply with statutory voting requirements, defense attorneys can move to dismiss indictments based on procedural violations that compromise the validity of charging decisions.

Procedural challenges require careful examination of grand jury records, voting tallies, and endorsement procedures to identify specific violations of statutory requirements.

Successful challenges to defective indictments may result in case dismissal or requirements that prosecution proceed by information rather than grand jury indictment, potentially affecting case strategy and plea negotiations.

Grand Jury Misconduct and Irregularities

Voting requirement violations may be part of broader grand jury misconduct that includes prosecutorial overreach, improper evidence presentation, or other irregularities that compromise the integrity of indictment proceedings.

Grand jury misconduct challenges often require extensive investigation of grand jury procedures, witness testimony, and prosecutorial conduct during secret proceedings that defense attorneys cannot directly observe.

Effective misconduct challenges may require cooperation with court personnel, grand jury members, or other individuals with knowledge of grand jury proceedings and potential irregularities.

Evidence and Discovery Considerations

Grand Jury Transcripts and Records

Defense attorneys may seek access to grand jury transcripts and voting records to verify compliance with statutory voting requirements while investigating potential grounds for challenging indictment validity.

Grand jury secrecy rules limit access to grand jury materials, but courts may authorize disclosure when necessary to evaluate procedural compliance or investigate potential misconduct affecting indictment validity.

Discovery strategies should address both immediate needs for challenging defective indictments and longer term case preparation that may benefit from understanding grand jury evidence and testimony.

Witness Testimony and Evidence Presentation

Grand jury voting decisions depend on evidence and testimony presented during secret proceedings, creating challenges for defense attorneys who must evaluate indictment validity without direct knowledge of grand jury deliberations.

Defense investigation of grand jury proceedings may focus on identifying witnesses who testified, documents that were presented, and prosecutorial conduct that may have influenced voting decisions.

Understanding the evidentiary basis for grand jury decisions helps defense attorneys evaluate case strength while developing strategies for challenging both indictment validity and underlying prosecution theories.

Prosecutorial Discretion and Charging Decisions

Alternative Charging Methods

When grand jury indictments are challenged or dismissed due to procedural violations, prosecutors may proceed by information or seek new grand jury indictments that comply with statutory requirements.

The availability of alternative charging methods means that successful challenges to defective indictments may not result in permanent case dismissal but rather require prosecution to cure procedural defects.

Defense strategies should consider both immediate benefits of challenging defective indictments and longer term implications for case development when prosecutors pursue alternative charging approaches.

Plea Negotiations and Case Resolution

Grand jury voting irregularities may provide leverage in plea negotiations by demonstrating weaknesses in prosecution cases or procedural violations that affect case strength and prosecutor confidence.

Negotiation strategies should account for the strength of procedural challenges while considering whether indictment defects actually affect case merits or merely require technical corrections.

Understanding voting requirement violations helps defense attorneys evaluate case strength while developing negotiation positions that account for both procedural challenges and substantive defense strategies.

Conclusion

California Penal Code Section 940 establishes important procedural safeguards for grand jury indictments while creating specific voting requirements that ensure adequate deliberation and support before criminal charges are formally filed. Defense attorneys must understand these requirements to effectively challenge defective indictments and protect client rights throughout the charging process.

The statutory voting thresholds reflect legislative judgment about appropriate standards for grand jury decision making while accommodating practical differences in grand jury size across different counties. These requirements supplement constitutional probable cause standards while creating additional procedural protections for defendants.

Effective defense representation requires comprehensive understanding of grand jury procedures, voting requirements, and available challenges to indictment validity.

Success depends on combining procedural challenges with substantive defense strategies that address both charging decisions and underlying case merits in pursuit of optimal outcomes for clients facing serious criminal charges.
