Duncan V. Louisiana Jury Trial Right Incorporation
Background: Right to Jury Trial and Incorporation
The Sixth Amendment guarantees the right to a trial by jury in "all criminal prosecutions." Originally, this applied only to federal courts. The Incorporation Doctrine through the Fourteenth Amendment has extended many Bill of Rights protections to the states, but not all rights have been incorporated.
1. Duncan v. Louisiana (1968)
Facts: Gary Duncan was convicted in Louisiana state court of simple battery, a misdemeanor punishable by up to two years in jail. Louisiana law did not provide jury trials for misdemeanors punishable by less than two years.
Issue: Does the Sixth Amendment right to a jury trial apply to state criminal trials under the Fourteenth Amendment?
Holding: Yes. The Court ruled that the right to jury trial is fundamental and applies to the states through the Due Process Clause of the Fourteenth Amendment.
Significance: Incorporated the right to jury trial in serious state criminal cases, defining "serious" as cases where imprisonment exceeds six months.
Outcome: Duncan’s conviction was reversed due to denial of jury trial.
2. In re Winship (1970)
Facts: A juvenile was adjudicated delinquent based on a preponderance of evidence.
Issue: Does the Due Process Clause require proof beyond a reasonable doubt in juvenile delinquency proceedings?
Holding: Yes. The Court held that the beyond-a-reasonable-doubt standard applies to juvenile adjudications that could lead to confinement.
Significance: Strengthened procedural protections in juvenile courts linked to serious deprivation of liberty, complementing Duncan’s recognition of fundamental trial rights.
3. Baldwin v. New York (1970)
Facts: Baldwin was convicted of a misdemeanor in New York with a sentence of one year, but he was denied a jury trial.
Issue: What is the dividing line between petty offenses (no jury required) and serious offenses (jury required)?
Holding: The Court held that offenses punishable by more than six months imprisonment require a jury trial.
Significance: Clarified the threshold for jury trial right under Duncan as offenses punishable by more than six months.
4. Williams v. Florida (1970)
Facts: Williams challenged the constitutionality of a 6-person jury.
Issue: Does the Sixth Amendment require a 12-person jury in criminal cases?
Holding: No. The Court ruled that smaller juries (minimum six members) satisfy the Sixth Amendment.
Significance: Allowed states to use smaller juries, provided the jury trial right is preserved.
5. Apodaca v. Oregon (1972)
Facts: Apodaca challenged a state court conviction by a non-unanimous jury verdict.
Issue: Does the Sixth Amendment require unanimous jury verdicts in state criminal cases?
Holding: The Court held that unanimity is required in federal courts but allowed non-unanimous verdicts (e.g., 10-2) in state courts.
Significance: Created a split in jury unanimity requirements between federal and some state courts.
6. Ballew v. Georgia (1978)
Facts: Challenged the constitutionality of 5-person juries in criminal trials.
Issue: Minimum jury size for Sixth Amendment compliance.
Holding: Juries must have at least six members; smaller juries violate the right to jury trial.
Significance: Reaffirmed Williams and established six as the minimum jury size.
Summary Table of Cases

| In re Winship | Proof beyond reasonable doubt in juvenile court | Due process requires high standard in juvenile proceedings | Strengthened juvenile trial rights |
| Baldwin v. New York | Threshold for jury trial right (petty vs serious) | Jury trial required if sentence > 6 months | Defined serious offense threshold |
| Williams v. Florida | Size of jury required | 6-person juries constitutional | Allowed smaller juries |

Conclusion
Duncan v. Louisiana is a cornerstone case in the incorporation of the Sixth Amendment right to a jury trial to the states, ensuring fair trial protections extend beyond federal courts. Subsequent cases have clarified the scope, including the minimum jury size, unanimity, and the seriousness of offenses requiring a jury.
