The Jury System in Texas: Selection, Duties, and Verdicts

The Texas jury system operates under a dual constitutional framework — the Texas Constitution and the U.S. Constitution — guaranteeing the right to jury trial in both criminal and civil proceedings. Jury composition, selection procedures, and verdict requirements differ between civil and criminal cases, and between state and federal courts operating within Texas. The framework governing Texas juries is codified primarily in the Texas Code of Criminal Procedure and the Texas Rules of Civil Procedure, administered through the court structure described at Texas Criminal Procedure.

Definition and Scope

A jury in Texas is a body of qualified citizens empaneled to determine questions of fact in judicial proceedings. Texas law recognizes two principal jury configurations:

Petit jury — the trial jury that hears evidence and returns a verdict in a specific case
Grand jury — a body of 12 citizens that evaluates prosecutorial evidence to determine whether a criminal indictment should issue (Texas Code of Criminal Procedure, Chapter 19)

Petit juries in Texas felony criminal cases consist of 12 jurors. Civil district court juries also consist of 12 jurors, though parties may stipulate to fewer under Texas Rules of Civil Procedure, Rule 218. In justice of the peace courts and county courts, civil juries consist of 6 members.

The right to a jury trial in criminal cases is protected by Article I, Section 15 of the Texas Bill of Rights. In civil cases, that right is protected by Article I, Section 15 as well, though statutory fee requirements and procedural timing rules govern when a jury demand is effective.

Scope and coverage limitations: This page addresses the Texas state jury system as it operates in state courts. Federal courts in Texas — including the four federal district courts — follow the Federal Rules of Criminal and Civil Procedure, which impose distinct jury selection and verdict standards not covered here. For the intersection of state and federal jurisdiction, see Federal vs. State Law in Texas. Proceedings in administrative tribunals and arbitration panels fall outside jury system coverage entirely.

How It Works

Jury Pool and Summons

The jury selection process begins with a venire — a panel of prospective jurors summoned from county voter registration and driver's license records, as authorized by Texas Government Code, Chapter 62. Each Texas county maintains its own jury wheel. Failure to appear in response to a valid jury summons constitutes contempt of court under Texas Government Code §62.0141.

Voir Dire

Voir dire is the oral examination of prospective jurors by the judge and attorneys. Its purpose is to identify bias, conflicts of interest, and statutory disqualifications. Texas law establishes absolute disqualifications from jury service, including:

Conviction of a felony (unless rights have been restored)
Being under indictment or facing other felony charges
Insanity or mental incapacity
Being a non-citizen
Being under 18 years of age

(Texas Government Code §62.102)

Beyond absolute disqualifications, attorneys exercise two categories of challenges:

Challenges for cause — unlimited in number; based on a demonstrated bias or legal disqualification
Peremptory challenges — limited in number by statute; in felony cases, each side receives 15; in misdemeanor cases, each side receives 10; in civil cases, each side receives 6 (Texas Code of Criminal Procedure Art. 35.15)

The U.S. Supreme Court's ruling in Batson v. Kentucky, 476 U.S. 79 (1986), prohibits the use of peremptory challenges to exclude jurors solely on the basis of race — a rule fully applicable in Texas state courts.

Deliberation

Once evidence and argument conclude, the jury retires to deliberate in private. The judge provides written jury instructions — the charge — which defines the legal standards jurors must apply. The Texas Pattern Jury Charges, published by the State Bar of Texas, are the standard reference for charge language in civil proceedings.

Common Scenarios

Felony criminal trial: A 12-member jury must reach a unanimous verdict of guilty or not guilty. If the jury cannot agree, the result is a hung jury and the court may declare a mistrial, permitting retrial.

Misdemeanor criminal trial in county court: A 6-member jury applies the same unanimity requirement.

Civil district court trial: A 12-member jury decides liability and damages. Under Texas Rules of Civil Procedure, Rule 292, a verdict may be rendered by 10 of 12 jurors — a notable departure from criminal unanimity requirements.

Capital murder sentencing: The jury's role extends beyond guilt determination. In capital cases, the same 12 jurors answer special issues under Texas Code of Criminal Procedure Art. 37.071, including whether the defendant constitutes a continuing threat to society — a finding required before a death sentence may be imposed.

Decision Boundaries

The distinction between criminal and civil jury standards is operationally significant:

Feature	Criminal Jury	Civil Jury
Size (district court)	12	12
Verdict threshold	Unanimous (12/12)	10 of 12
Burden of proof	Beyond reasonable doubt	Preponderance of evidence
Hung jury result	Mistrial permissible	Mistrial permissible
Peremptory challenges	15 (felony) / 10 (misdemeanor)	6 per side

The regulatory context governing Texas courts — including the Texas Office of Court Administration's oversight role — shapes how jury management operates at the county level, from summons compliance tracking to courtroom administration.

Grand juries operate entirely outside the trial framework: they do not determine guilt, hear defense evidence as a matter of right, or apply a reasonable doubt standard. Their sole function is to determine whether probable cause supports an indictment. The Texas Court of Criminal Appeals serves as the court of last resort for criminal matters arising from jury verdicts, including challenges to jury charge errors and voir dire rulings.
