Amendment VIII
Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted.
The penalties are excessive because the requirement is excess.
Amendment IX
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
Taken with the 10th it Constitutionally limits the interstate commerce clause to enumerated powers not any general welfare canard.
When has the SC cared anything about the constitution? I have yet to find that they can read.
