The Burden of Proof

It is the State that bears the burden of proof in all criminal cases. What this means is that it is the prosecution’s job to establish every element of a crime to the high standard of “beyond a reasonable doubt.” Here, if there is any reasonable question about what happened and if there is uncertainty, then the defendant must be found not guilty. As a result, the prosecution has a challenging job to make sure that their narrative is one that is clear, persuasive, and that no one who hears it has any misgivings about what transpired.

Domestic Battery in Illinois

Illinois state law 720 ILCS 5/12-3.2 defines domestic battery as an occurrence where someone knowingly causes bodily harm to a family member or household member, or makes physical contact of an insulting or provoking nature. This interpretation may seem straightforward and relatively benign, but in practice, the reality is that it can be incredibly complicated.

Bodily Harm and Insulting or Provoking Contact

Illinois does not require that a serious injury result in order to have bodily harm. For instance, if someone inflicts minor bruising or pain, then this can be enough for prosecutors to claim that there was harm done. Although it is still necessary to prove that the bodily harm not only happened but was caused by the defendant.

Insulting or providing contact is a little more subjective. Depending on context and how sequences of events are understood, a slap, a shove, or even grabbing another person’s wrist could qualify as “provoking”.

Self-Defense, Mutual Combat, and the Question of Aggression

Often, domestic battery cases in Illinois stem from mutual arguments or physical confrontations where all parties involved claim they are the victim. This is where determining who was actually the aggressor is so important. It is possible, under the law, to use reasonable self-defense if a person believes they are in danger of harm. Sometimes, all individuals may have willingly engaged in physical contact, which is known as mutual combat. Should this happen, a case can become even more complicated for the prosecution.

Evidence and Credibility

If there is concrete evidence, such as photos of injuries, medical records, camera footage, 911 recordings, or surveillance videos, this can be difficult to overcome and directly affect how a case is decided. On the other hand, inconsistent statements or a lack of physical proof can lead to reasonable doubt.
