Do you think Roe v. Wade is "good law"?
First of all RvW is not a Law. It is a ruling of the USSC about a Texas law. There is no chance it could have passed as a law and that is what makes it so objectionable an example of judicial activism and overreaching. It is completely different that this case which in no way is an example of courts going outside the law and just making it up.
Second the actual laws regarding Guardianship and medical procedures are made by the representatives of the people of the states and are all fairly similiar in terms of who guardianship passed to after incapacity. Normally they operate smoothly and without much controversy and decisions such as that made by MS are carried out hundreds of times a day in this country. This would have all been over years ago had not the In Laws gone to court and dragged it out for 7 years.
