Aggravated Second Degree Battery Defense in Louisiana

Written by Jarrett Ambeau, trial attorney, court-qualified forensic DNA expert, and lead counsel at The Ambeau Law Firm.

What is aggravated second degree battery in Louisiana? Under La. R.S. 14:34.7, it is a battery committed with a dangerous weapon when the offender intentionally inflicts serious bodily injury. It requires both a dangerous weapon and an intentional serious injury, and it is a felony punishable by up to fifteen years and a fine of up to ten thousand dollars.

This is one of the more serious battery charges in Louisiana, short of a homicide. It requires the state to prove not just a weapon, but an intentional serious injury. That is a demanding standard, and it is where these cases are frequently won. The gap between a serious injury and the legal definition of serious bodily injury can decide the outcome.

I am Jarrett Ambeau. I have tried more than sixty felony jury trials to verdict. In a case like this, I focus the defense on the two elements the state must prove and often struggles to: a dangerous weapon and intentional serious bodily injury.

Quick answers

• What it is: a battery with a dangerous weapon that intentionally inflicts serious bodily injury (La. R.S. 14:34.7).
• The penalty: up to fifteen years with or without hard labor, and a fine of up to $10,000.
• The key issue: whether the injury meets the legal definition of serious bodily injury and whether it was intentionally inflicted.
• What to do first: stay silent with police and get a trial lawyer involved immediately.

What counts as aggravated second degree battery in Louisiana?

The charge requires three things working together: a battery, the use of a dangerous weapon, and an intentionally inflicted serious bodily injury. A dangerous weapon is any object that, as used, is likely to cause death or great bodily harm. Serious bodily injury is a defined legal term involving things like unconsciousness, extreme pain, disfigurement, or a substantial risk of death. Each of these is a separate hurdle the state must clear.

Elements the State must prove

To convict, the state must prove beyond a reasonable doubt:

• A battery. The intentional use of force or violence on the victim.
• A dangerous weapon. An object likely, as used, to cause death or great bodily harm.
• Intentional serious bodily injury. That the offender intentionally inflicted an injury meeting the legal definition.
• Without justification. That the conduct was not self-defense or otherwise justified.

What happens after an arrest in Louisiana?

Say a man named Joe is arrested. Within seventy-two hours he has an initial appearance where bond is addressed. Because this is a felony, if he is held the state generally has sixty days to bring formal charges. Then arraignment, the motions phase, and trial. In the motions phase we examine the medical records, challenge the claim of intentional serious injury, and test any statements. That work often shapes the case.

What are the defenses to aggravated second degree battery?

The defenses that come up most often include:

• The injury was not serious bodily injury. Challenging whether the injury meets the strict legal definition, which can reduce the charge.
• No intent to inflict serious injury. That any serious injury was not intended.
• Self-defense. Reasonable force against an imminent threat, which the state must disprove.
• No dangerous weapon. That the object used does not meet the legal standard.
• Misidentification. That someone else caused the injury.

How we defend an aggravated second degree battery charge

Because these cases turn on medical proof and intent, we scrutinize the medical records and the injury itself. We gather the evidence, talk to witnesses, and look for video, and we build the timeline the state would rather ignore. With more than sixty felony jury trials to verdict, we know how to challenge whether the state can meet each element.

Where the facts allow, we push to reduce the charge to aggravated or simple battery, or to have it dismissed. The difference in exposure is enormous. Early, aggressive representation makes a real difference. It is what we do here at The Ambeau Law Firm.

Frequently asked questions

What is aggravated second degree battery in Louisiana?

Under La. R.S. 14:34.7, aggravated second degree battery is a battery committed with a dangerous weapon when the offender intentionally inflicts serious bodily injury. It combines two elements that raise the stakes beyond ordinary battery: the use of a dangerous weapon and an intentional serious injury. It is a felony carrying up to fifteen years.

What is the penalty for aggravated second degree battery in Louisiana?

It is punishable by a fine of up to ten thousand dollars, imprisonment with or without hard labor for up to fifteen years, or both. If the offender knew the victim was an active-duty service member or disabled veteran and acted because of that status, at least one year must be served without benefit of parole, probation, or suspension of sentence.

How is it different from aggravated battery?

Aggravated battery under La. R.S. 14:34 requires a battery with a dangerous weapon, but no particular injury. Aggravated second degree battery under La. R.S. 14:34.7 adds a requirement: that the offender intentionally inflicted serious bodily injury. Because it demands proof of both a dangerous weapon and intentional serious injury, the state has more to prove, and more that can be challenged.

What counts as serious bodily injury?

Serious bodily injury generally means an injury involving unconsciousness, extreme physical pain, protracted or obvious disfigurement, or a substantial risk of death or lasting impairment of a body part or organ. Whether an injury meets that legal threshold, rather than being a lesser injury, is frequently a central and contested issue in these cases.
