State of Louisiana v. Catina Curley, 250 So. 3d 236

Background

Catina Curley shot and killed her husband during a separation; disputed testimony about whether the shooting was accidental or in self-defense.
Extensive testimonial and documentary evidence at trial showed years of prior domestic violence by the victim against Curley and family members.
Trial counsel withdrew a prior not guilty by reason of insanity (NGBRI) plea shortly before trial and then pursued self-defense and accidental-discharge theories without consulting or calling a Battered Woman's Syndrome (BWS) expert.
At trial the jury convicted Curley of second-degree murder and she was sentenced to life imprisonment; the conviction was affirmed on direct appeal.
On post-conviction review, Curley argued ineffective assistance of counsel for failing to investigate and present expert BWS testimony; the trial court granted relief but the court of appeal reversed.
The Louisiana Supreme Court held counsel’s failure to investigate/present BWS expert testimony was deficient and prejudicial under Strickland and vacated the conviction and sentence, remanding for a new trial.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether counsel’s failure to investigate/present BWS expert constituted deficient performance	Curley: counsel was ignorant of BWS, failed to investigate or seek expert, so representation was unreasonable	State: counsel’s choices were strategic and the record did not show counsel’s omission was unreasonable	Held: deficient—counsel made no reasonable investigation into BWS or expert testimony and admitted ignorance; this fell below objective standard under Strickland
Whether BWS/expert testimony is admissible outside an insanity plea	Curley: BWS is relevant to self-defense and admissible under domestic battery exceptions	State: Louisiana historically limited psychological evidence to insanity context; court of appeal treated BWS as relevant only to NGBRI	Held: BWS expert testimony is admissible in justification/self-defense cases under La. C.E. arts. 404(A)(2)(a) and 404(B)(2) and Rodrigue
Whether counsel’s withdrawal of NGBRI plea without evaluation caused Strickland prejudice	Curley: withdrawing the plea and not evaluating BWS/insanity foreclosed useful evidence and expert testimony	State: no evidence expert would have shown insanity or inability to distinguish right from wrong; no prejudice	Held: no prejudice shown as to NGBRI claim (no evidence of insanity), but overall prejudice shown because expert testimony could have aided self-defense/mitigation and undermines confidence in outcome
Whether prejudice requires probable acquittal or lesser showing	Curley: reasonable probability of a different result is enough (not necessary acquittal)	State: defendant must prove reasonable probability of different outcome; courts must be concrete about what expert would have shown	Held: Strickland requires reasonable probability sufficient to undermine confidence in outcome; court finds prejudice satisfied because expert testimony was admissible and reasonably likely to have affected jury's assessment or mitigation
