Re: Which Law Would Supersede?
Neither supersedes the other. They are each laws dealing with different situations. In the first, the state cannot mandate a child attend school once they reach 17. In the other, it is dealing with the parent child relationship.
In short, it is not the choice of the 17 yo to decide to not attend school regardless of the fact the state will not compel a child 17 or over to attend school. If you refuse to obey the rules your parents impose upon you, they can seek the assistance of the courts. If that results in being put in some sort of care or treatment, then it is what it is. If it results in the child being placed on some sort of probation type program, then it is what it is.
In short, if a 17 year old does not wish to go to school can his parents legally force him to or have the ability to have him put in some sort if care, treatment, or supervision?
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
