Not solely because of the rape.
Before this law, a court could only terminate a rapist's parental rights if someone proved the rapist was an unfit parent. The state could ask for parental rights termination in a dependency, a court action where the state tries to take the children away from both parents.
In an adoption case, a judge could terminate a parent's rights.
Now you can do this without the state's involvement. If you can prove the child was born because of a rape, you can decide what parental rights you want the rapist to have, if any.
