State of Louisiana v. Davieontray Lee Breaux, 408 So.3d 899

Davieontray Lee Breaux was indicted for two counts of first-degree murder and three counts of attempted first-degree murder after a single incident in which he allegedly shot five people, killing two.
The State sought the death penalty for the first-degree murder charges, making these capital offenses.
Breaux moved to quash the indictment, arguing that capital and non-capital felony charges cannot be joined for trial under Louisiana law.
The trial court denied the motion, deciding recent legal changes made joinder permissible.
The Louisiana Court of Appeal denied review, but the Louisiana Supreme Court granted writ to resolve the issue.

Issue	Breaux’s Argument	State’s Argument	Held
Whether capital and non-capital felony charges may be joined for trial under Louisiana law	Joinder of capital with non-capital charges is prohibited by La. Const. art. I §17 and longstanding jurisprudence	Joinder is allowed since all felonies now require a 12-member unanimous jury; historic reason for the ban no longer applies	Joinder is prohibited; indictment quashed
Whether the "same mode of trial" requirement permits joinder after legal reforms	"Mode of trial" includes more than jury size or unanimity; capital trials are fundamentally different	"Mode of trial" now only refers to the number of jurors and verdict concurrence, eliminating differences	Capital cases’ unique procedures still require separate trials
Effect of recent constitutional amendments and Ramos v. Louisiana on existing jurisprudence	Amendments did not alter the constitutional prohibition on joinder of capital and non-capital offenses	Such changes mean underlying reason for ban is gone; policy supports efficiency	Constitutional text and intent still bar joinder
Importance of judicial economy vs. defendant prejudice in misjoinder context	Joinder risks prejudice and is constitutionally forbidden regardless of judicial economy	No increased prejudice; evidence overlaps; separate trials would cause administrative burden	Textual and historical bars to joinder control, not judicial economy
