Why Some States Use Grand Juries and Others Don’t

Bridge Legal Team

Across the United States, the charging process in criminal cases varies by state. While the grand jury system is a hallmark of many jurisdictions, several states rely on other mechanisms such as information filings or preliminary hearings. This article explains why differences exist, how they work in practice, and what they mean for defendants, prosecutors, and the administration of justice.

What A Grand Jury Does

A grand jury is a group of citizens convened to review evidence presented by a prosecutor to determine whether there is probable cause to charge someone with a crime. Indictments—formal accusations—often arise from grand juries. Grand juries typically operate in secret, with prosecutors presenting evidence and witnesses without the accused present. The process aims to vet serious charges and provide a check on prosecutorial power, though critics point to secrecy and potential biases. In states that rely on grand juries, indictments for felonies usually require a grand jury decision rather than a judge granting charges directly.

How States Decide Between Grand Juries And Other Methods

States differ in whether charging decisions for felonies are made by a grand jury, by information filed by a prosecutor, or after a preliminary hearing. Key factors shaping these decisions include constitutional provisions, historical practice, and practical concerns such as cost and efficiency.

  • Constitutional and statutory frameworks: Some state constitutions explicitly authorize or require grand juries for felonies, while others give prosecutors discretion to file an information or proceed by preliminary hearing, depending on statutes and court rules.
  • Historical tradition: States with long-standing common-law traditions often preserved grand juries as a central feature, whereas states that reformed their systems in the 20th or 21st century may have shifted toward more modern procedures like information-based charging.
  • Practical considerations: Grand juries can add time and cost to the process and may limit the defendant’s ability to influence the charging decision early. States seeking speed, predictability, or transparency may favor charging mechanisms that involve judges or open hearings rather than secret proceedings.
  • Judicial oversight and defense rights: Preliminary hearings and information-based charging provide early judicial review and may be more accessible to defendants, influencing reform in some regions.

Common Approaches Across States

While there is variation, several broad patterns emerge in how states handle criminal charging:

  • Grand jury states: In these states, a grand jury typically determines whether there is probable cause to indict felonies. The process is usually secret, and an indictment is required before formal charges proceed to trial in many cases.
  • Information-based charging states: Some jurisdictions allow prosecutors to file an information—a formal accusation signed by the prosecutor and approved by a judge or magistrate—without a grand jury. This often occurs for many felonies and misdemeanors alike, depending on the offense and state rules.
  • Preliminary hearing states: In other areas, prosecutors may bring a case before a judge in a preliminary or probable cause hearing. If the judge finds probable cause, charges proceed; if not, the case can be dismissed or charges refined.
  • Hybrid systems: A number of states maintain both options, using grand juries for certain offenses (such as capital cases) and information or preliminary hearings for others, or allowing prosecutors to choose among methods under specific conditions.

Historical And Legal Factors Shaping The Landscape

Several enduring factors influence why a state maintains or discards grand juries:

  • Size and structure of the state judiciary: Larger states with dense caseloads may favor more streamlined charging to manage workload, impacting the continued use of grand juries in some counties.
  • Local norms around prosecutorial discretion and accountability can drive openness to information-based charging or maintain traditional secrecy in grand juries.
  • Reform movements have highlighted issues like secrecy in grand juries and unequal access to the charging process, prompting some states to adopt reform-minded mechanisms with greater public oversight.
  • For serious offenses, some jurisdictions reserve grand jury proceedings or rely on specialized grand juries to ensure thorough review, while less severe cases proceed through other channels.

Practical Implications For Defendants And Prosecutors

Charging processes influence multiple aspects of the criminal justice journey:

  • Defense strategy: Grand jury secrecy can limit defense access to evidence at an early stage, whereas information-based charging and preliminary hearings reveal more information and allow earlier defense input.
  • Case duration and leverage: Grand juries can extend the timeline before formal charges, while information-based or preliminary hearing approaches may shorten the period to arraignment and trial.
  • Transparency and accountability: Public charging mechanisms (preliminary hearings, open courts) can enhance transparency, while grand jury secrecy prioritizes confidentiality but may raise concerns about potential prosecutorial bias.
  • Appeals and post-charge review: The avenue for challenging charges varies with the method—indictments, informations, or preliminary orders each have distinct procedural paths for defense challenges.

Key Takeaways For The American Legal Landscape

– The United States does not have a single nationwide method for initiating criminal charges; states choose based on constitutional directives, history, and policy goals.

– Grand juries remain a foundational feature in many states for certain felonies, providing an extra layer of review before indictments are issued.

– Information filings and preliminary hearings offer quicker, more transparent charging avenues in other states, prioritizing efficiency and early judicial involvement.

– Understanding a state’s charging scheme is essential for defendants, attorneys, and policymakers, as it shapes opportunities for defense, timelines, and the balance between secrecy and accountability.
