Indiana Jury System: Selection, Duties, and Grand Jury Process
Indiana's jury system operates as a constitutional mechanism for citizen participation in the state's judicial process, governing both criminal and civil proceedings through distinct procedural frameworks. This page covers the structure of petit juries and grand juries in Indiana, the legal standards governing juror selection and service, the duties assigned to jurors across case types, and the boundaries that separate state jury practice from federal jury procedures. The Indiana Trial Court Procedures page provides complementary procedural context for how jury trials fit within the broader litigation sequence.
Definition and scope
The right to a jury trial in Indiana is grounded in two constitutional provisions: Article I, Section 20 of the Indiana Constitution guarantees the right to jury trial in civil cases, while the Sixth Amendment of the U.S. Constitution — as applied to states through the Fourteenth Amendment — guarantees it in criminal prosecutions (Indiana Constitution, Article I). Indiana Code Title 33, Articles 28 and 33, governs jury selection, qualification, and service for state courts (Indiana Code Title 33, Indiana General Assembly).
Indiana operates two distinct jury types:
- Petit jury — the trial jury that hears evidence and returns a verdict in civil or criminal cases. Criminal petit juries consist of 12 jurors; civil juries may consist of 6 jurors in some proceedings.
- Grand jury — a body of citizens, typically 12 members in Indiana, that evaluates prosecutorial evidence in secret to determine whether probable cause supports formal criminal charges via indictment.
The Indiana jury system applies across the state's 92 counties, each of which maintains its own jury pool drawn from the county's registered voter rolls and, in Indiana, from Bureau of Motor Vehicles license and ID records under Indiana Code § 33-28-5-2. This page covers Indiana state court jury processes and does not address federal jury selection procedures governed by the Jury Selection and Service Act of 1968 (28 U.S.C. § 1861 et seq.), which apply to the U.S. District Court for the Northern District of Indiana and the U.S. District Court for the Southern District of Indiana. Tribal court proceedings and private arbitration panels are outside this scope.
How it works
Juror qualification and pool assembly
Indiana assembles jury pools by randomly selecting names from two source lists: registered voters and licensed drivers or ID cardholders from BMV records. Under Indiana Code § 33-28-5-7, a prospective juror must be a U.S. citizen, at least 18 years of age, a resident of the county in which service is required, able to communicate in English, and free of a felony conviction unless civil rights have been restored.
Voir dire (juror examination)
After a pool is summoned to the courtroom, attorneys and the judge conduct voir dire — oral questioning designed to surface bias or conflicts of interest. Attorneys exercise 2 types of challenges:
- Challenges for cause — unlimited in number; require demonstrated bias or statutory disqualification.
- Peremptory challenges — limited in number by court rule; allow dismissal without stated reason, subject to the restriction that race- or sex-based peremptory strikes are unconstitutional under Batson v. Kentucky (476 U.S. 79, 1986) and J.E.B. v. Alabama (511 U.S. 127, 1994).
Trial jury deliberation
Once evidence is presented and closing arguments concluded, the jury retires to deliberate in private. Indiana criminal cases require a unanimous verdict from all 12 jurors for conviction. Civil cases may proceed with a 6-person jury, and Indiana Rules of Trial Procedure allow for a verdict by agreement of 5 of 6 jurors in civil matters (Indiana Rules of Trial Procedure, Rule 48, Indiana Judiciary).
Grand jury process
Indiana's grand jury process, governed by Indiana Code § 35-34-2, functions as an investigative and charging body. The grand jury convenes in secret, hears evidence presented exclusively by the prosecutor, and issues an indictment if at least 7 of 12 grand jurors find probable cause. Unlike trial juries, grand juries do not determine guilt; witnesses before a grand jury have no right to have counsel present in the room during questioning, though they may consult counsel outside. Grand juries in Indiana may also issue presentments — formal reports on public matters — without necessarily returning criminal charges.
Common scenarios
Indiana jury service arises across three primary case categories:
Criminal felony trials — Defendants charged with Level 1 through Level 6 felonies under Indiana Code Title 35 are entitled to a 12-person jury. The state bears the burden of proof beyond a reasonable doubt.
Civil jury trials — Disputes meeting the threshold for Circuit or Superior Court jurisdiction proceed with a jury upon timely demand. Tort cases, contract disputes, and property matters commonly use the civil jury mechanism. The Indiana Civil vs. Criminal Law page distinguishes the evidentiary standards — preponderance of the evidence in civil proceedings versus beyond a reasonable doubt in criminal trials.
Grand jury investigations — Prosecutors invoke grand juries when investigating complex criminal conduct — organized crime, public corruption, or multi-defendant conspiracies — where the grand jury's subpoena power and secrecy provisions serve investigative purposes beyond what a preliminary hearing affords.
Decision boundaries
Several threshold conditions determine whether and how jury proceedings apply:
| Condition | Jury applies? | Notes |
|---|---|---|
| Criminal felony charge | Yes | 12-person jury; unanimous verdict required |
| Criminal misdemeanor | Conditional | Right exists but may be waived; bench trial common |
| Civil case, damages claimed | Yes, if timely demand filed | 6-person jury standard in Indiana civil practice |
| Small claims court | No | Indiana Small Claims Court proceedings are bench trials only |
| Grand jury indictment vs. information | Discretionary | Prosecutor may charge by information without grand jury in most Indiana felony cases |
| Federal court in Indiana | No (state rules inapplicable) | Federal jury standards under 28 U.S.C. § 1861 et seq. govern |
The regulatory context for Indiana's legal system provides the statutory and constitutional framework within which these decision thresholds operate. Indiana does not require grand jury indictment for felony prosecutions — unlike federal practice under the Fifth Amendment — because Indiana's Constitution does not mandate grand jury indictment as a prerequisite to felony charges. Prosecutors may file a charging information directly, making grand jury proceedings discretionary rather than mandatory at the state level.
Juror conduct after empanelment is regulated by Indiana Jury Rule 20, which prohibits independent investigation, outside communication about the case, and — notably — restricts juror access to social media research on parties or witnesses (Indiana Jury Rules, Indiana Judiciary). Violations may result in mistrial, juror removal, or contempt proceedings.
