SB 419 Wisconsin Senate · 2025-2026 Regular Session

Relating to: emergency testing of a criminal defendant for certain diseases. (FE)

SB 419 allows courts to order emergency testing for certain diseases (like HIV or STIs) of criminal defendants without their consent in specific cases. It applies when a defendant allegedly committed a crime involving bodily fluids (blood, semen, etc.) that could transmit disease to public safety workers, prosecutors, or correctional staff. The bill requires court approval based on probable cause, mandates immediate disclosure of results to the defendant, and prohibits adding test results to the person's permanent medical record. It also creates new procedures for prosecutors to seek these orders quickly when public safety is at risk. This bill directly affects criminal defendants in cases involving potential disease transmission to protected public safety personnel.
