Under Illinois DUI law, whether a DUI is charged as a misdemeanor or felony depends in part on whether any enhancing factors exist such as whether the defendant committed any prior violations of the DUI statute. While the Supreme Court of Illinois has definitively stated a previous conviction of the DUI is not necessary to prove a defendant committed a violation, it has not defined the scope of what evidence is admissible to establish a violation. While it is not precedential, in State v. Hastey the Maine Supreme Court recently held that extrinsic evidence outside of a DUI charge or conviction is admissible as evidence of an enhancing factor in charging a defendant with an aggravated DUI. If you face DUI charges and were previously charged with DUI, an experienced Illinois DUI attorney can help you determine what evidence the state may attempt to introduce against you and assist you in formulating a defense.
Facts of the Case
Purportedly, in Hastey, the defendant was charged with aggravated criminal OUI. Under Maine law, a person commits aggravated criminal OUI if he or she operates a motor vehicle while under the influence of intoxicants and has a prior criminal homicide conviction resulting from the operation of a motor vehicle while under the influence of intoxicants.
