Prohibits the use of DNA phenotyping in criminal prosecutions and proceedings

This bill prohibits law enforcement agencies from using or contracting for DNA phenotyping, which predicts physical traits (like eye color or ancestry) from DNA samples, in criminal investigations or prosecutions. It bans all evidence derived from this technology from being used as reasonable cause for arrest or in court, and requires existing DNA phenotyping data held by police to be destroyed immediately. Any conviction linked to such evidence becomes eligible for legal review. The law directly affects police departments, prosecutors, and criminal court proceedings by eliminating a specific investigative tool.
