A night out with friends can take an unexpected turn when tensions rise and tempers flare. One moment you are having fun, and the next you find yourself in a fight. You may assume that a mutual confrontation between two adults is simply a personal matter.
Law enforcement, however, can treat a bar fight as a crime, regardless of who started it. This blog will explore how assault is defined and what you can do when accused of it.
What counts as assault in South Dakota?
The state defines assault more broadly than most people realize. Under the law, the following actions can count as simple assaults:
- Attempting to cause an injury when you have the actual ability to inflict harm
- Recklessly causing an injury through actions
- Intentionally causing an injury that does not rise to the level of serious harm
- Using physical threats or menacing behavior to put someone in fear of imminent harm
That last point is particularly important for bar fight situations. Even if you never land a punch, raising your fists, making verbal threats while advancing toward someone or cornering another person could meet the legal definition of assault.
Aggravated assault is a more grievous offense with harsher penalties. It applies when you or your opponent cause or attempt to cause serious bodily harm, use a dangerous weapon or assault a protected person, such as a police officer.
Does self-defense apply in bar fights?
South Dakota follows “stand your ground” laws, meaning you have no legal obligation to retreat before defending yourself. You may use reasonable force if you genuinely believe it is necessary to protect yourself from imminent unlawful force.
This, however, does not mean that you can deal with your opponent as you see fit. Self-defense law requires your response to match the threat encountered. If someone shoves you and you respond by breaking a bottle over their head, the force you used would likely be considered excessive.
The timing of the threat also matters. If an argument ends and you follow the other person outside to continue the confrontation, you cannot claim you were defending yourself.
It is also worth noting that if you agree to fight someone, whether through words or actions, you may forfeit your right to claim self-defense. Prosecutors often use witness statements and security footage to establish whether both parties willingly engaged in the altercation.
What penalties could you receive?
South Dakota classifies simple assault as a Class 1 misdemeanor. A conviction can send you to county jail for up to one year, require fines up to $2,000 and create a permanent criminal record that may appear on background checks.
For aggravated assault, the state treats it as a Class 3 felony, with potential penalties of up to 15 years in state prison and fines reaching $30,000. Courts escalate the consequences if you have prior criminal convictions or if the victim suffered particularly serious injuries.
Courts also treat repeat simple-assault convictions more severely. If you have two or more prior qualifying assault convictions within ten years, the state elevates a third offense to a Class 6 felony, punishable by up to two years in state prison and fines up to $4,000. Fourth and fifth offenses carry progressively harsher penalties, potentially reaching Class 4 felony status.
Could legal representation make a difference?
If you have been accused of assault because of a fight, having an attorney on your side might help your situation. They can review the evidence against you, identify weaknesses in the prosecution’s case and determine whether self-defense or other legal arguments apply to your circumstances.
