During the investigation of child sexual abuse, if the perpetrator is a Catholic, they’ll ask if the abuser confessed. If so, the priest is liable to be prosecuted.
Honestly, my biggest problem with the law is how unlikely it is to ever be prosecuted. Proving that an abuser confessed would be impossible. They are infringing on the First Amendment and ensuring that no abuser ever talks to their priest, but in practice priests probably won’t follow the law and if they don’t the state is unlikely to actually enforce the law.
This is wildly outside of the mainstream interpretation of the first amendment. Whether the law would be upheld by the court is basically a toss up.
