This was not a states rights decision at all. Look at who voted to uphold the Oregon suicide law. They have absolutely no concern over states rights. This is strictly a right to die/kill decision. They are terrified of any decision that might even open the door a fraction of an inch that the government's responsibility to protect life trumps the idea to an absolute right to not be inconvenienced by a baby or an aging adult that must be cared for.
Still waiting to read the dissent opinion.
There are people arguing here that your life is your own to end as you wish. Then why, in Oregon, did the people put the responsibility for euthanasia onto doctors? It seems all too cowardly to me; if you believe in suicide, then do it unassisted. Don't get doctors and governments involved.
I also question how committed to states' rights, the majority opinion justices are...
