Understanding Self-Defense Law in New Jersey: A Breakdown of State v. Martinez

New Appellate Division Decision on Self-Defense Law in New Jersey

On January 23, 2025, the Superior Court of New Jersey, Appellate Division, issued a significant decision in State of New Jersey v. Stephanie Martinez, ___ N.J. Super ___ (App. Div. 2025). This case explored the applicability of self-defense as a complete defense for homicide. The appellate court ultimately reversed the defendant’s conviction for passion/provocation manslaughter on the basis of improper jury instructions, while remanding her other convictions for resentencing. This decision underscores key principles in Self-Defense Law in New Jersey and its implications for future cases.

Facts and Procedural History of State v. Martinez

In September 2021, Stephanie Martinez killed Raul Rios during a confrontation that escalated into violence. Martinez testified that Rios, under the influence of drugs and alcohol, sexually assaulted her and threatened to kill her. Fearing for her life, Martinez fatally stabbed Rios while they were in his vehicle. Martinez then drove to a local store and used Rios’ credit card to buy cigarettes and a cup of coffee, purportedly to calm herself. At some point, possibly when Rios was already deceased, his arm twitched startling Martinez, so she struck him two or three times with a crowbar and then disposed of his body in a parking lot.

Martinez was charged with murder, felony murder, robbery, kidnapping, and related offenses. The verdict sheet listed four categories of homicide: murder, passion/provocation manslaughter, aggravated manslaughter, and reckless manslaughter. The jury found that the State did not disprove, beyond a reasonable doubt, the applicability of self-defense as to murder, thereby acquitting her of that charge. However, the jury then found that the State had disproved, beyond a reasonable doubt, the applicability of self-defense as to the passion/provocation manslaughter charge, finding her guilty. The trial court sentenced her to seven years in prison under the No Early Release Act. The case hinged on whether the jury’s finding of self-defense as to murder amounted to an acquittal on the passion/provocation charge.

The Court’s Analysis of Self-Defense Law in New Jersey

The Appellate Division considered the facially inconsistent verdicts due to the jury’s finding that self-defense was established as to murder but not passion/provocation manslaughter. The court set forth that although inconsistent verdicts are generally not disturbed, the inconsistency was untenable in this case because Under Self-Defense Law in New Jersey, self-defense is a complete defense to all forms of homicide.

The court also identified errors in the trial court’s jury instructions and verdict sheet, which failed to convey that a finding of self-defense for one category of homicide bars conviction on any other homicide charge. This misapplication of the law necessitated the reversal of Martinez’s passion/ provocation manslaughter conviction.

Implications for Criminal Defense Attorneys in New Jersey

This ruling reaffirms that self-defense is a complete defense to all forms of homicide under New Jersey law. For a self-defense claim to succeed, the defendant must demonstrate a reasonable belief that deadly force was necessary to protect against serious harm or death. The Appellate Division emphasized the importance of accurate jury instructions in cases involving Self-Defense Law in New Jersey, as errors in a jury charge can constitute reversible error.

The Appellate Division also recommended that the Model Criminal Jury Charge Committee develop clearer templates for verdict sheets in cases where self-defense applies to multiple homicide charges, aiming to prevent future inconsistencies.
