Here is a sample of constitutional amendments from nine Scotus blackrobes:
Helvering v. Davis. Congress can collect and distribute taxes to promote the general welfare. It opened the floodgates to income redistribution.
Wickard v. Filburn. Blew the commerce clause to pieces. Congress can regulated just about anything.
Whitman v. American Trucking Associations. Administrative agencies can pass regulations with the force of law.
Baker v. Carr. One man one vote democratized state legislatures in a fashion similar to the 17th Amendment.
There are probably dozens of other Scotus rulings that have effectively rewritten the constitution.
