Narrative Opinion Summary
The Illinois Appellate Court in *Villareal v. Peebles* affirmed the trial court's determination of paternity and child support obligations, finding Juan Peebles to be the natural father of a minor child based on evidence presented, including DNA RFLP testing. The plaintiff claimed Peebles was the father following a sexual encounter, supported by a combined paternity index (CPI) of 2,582 to 1. Peebles contested the admissibility of the DNA test results and the sufficiency of the CPI, arguing for a higher threshold based on expert testimony. However, the court found the statutory presumption of paternity under section 11(f) of the Illinois Parentage Act, which requires a CPI of at least 500 to 1, was not successfully rebutted by the defendant's evidence. Peebles also challenged the constitutionality of section 11(f), but the court held that this argument was waived as it was not raised at trial, and notice to the Attorney General was not timely. The appellate court upheld the trial court's decision, confirming Peebles' paternity and associated support obligations, given the lack of clear and convincing evidence to counter the statutory presumption and the untimeliness of the constitutional challenge.
