in illinois the age of consent is 17. but do parents of the younger person still have right to press charges? even though that person has reached the age of consent?

A seventeen year old can consent to have sexual contact in Illinois; however, the age of majority in Illinois is 18. Until you are 18 years of age, you are a "minor" under the legal authority of your parents or legal guardians. This means that parents still have legal authority, responsibility, and accountability for the welfare and control of their minor child. They are within their authority to pursue legal action, if necessary, to maintain control until their minor child legally becomes an adult.
