Judge: No credible evidence underage sex always harmful ROXANA HEGEMANAssociated PressWICHITA, Kan. - A federal judge hearing a constitutional challenge to a Kansas law requiring doctors, teachers and others to report underage sex between consenting youths said the state presented no credible evidence that underage sex is always harmful. U.S. District Judge J. Thomas Marten stopped short of issuing a decision from the bench, but he repeatedly interrupted Thursday's closing arguments by Assistant Attorney General Steve Alexander to challenge his assertions. "Motives are irrelevant - I want to deal with facts," Marten said. "Where is the clear, credible evidence that underage sex is always injurious? If you tell me because it is illegal - I reject that," Marten said. The lawsuit filed by The Center for Reproductive Rights, a New York advocacy group, stems from a 2003 opinion issued by Kansas Attorney General Phill Kline's opinion requiring health care providers and others to tell authorities about consensual sex by underage youths. The group contends that forced reporting discourages adolescents from seeking counseling and medical treatment and violates their rights to informational privacy. The Attorney General's Office contends the statute requires mandatory reporting because sex is inherently harmful to underage children. In Kansas, the age of consent is 16.
