Are the goals and objectives of the constitution, such as rule of law, relevant today?

I would say yes, the goals and objectives of the constitution are still relevant today.  When the constitution says, "Establish Justice", it is implying they want to set up a legal system fair to all, which indeed is very important today.  It also ensures domestic tranquility, which protects us all from unlawful acts.  Lastly, it provides us common defense, which is protection from other countries.Hope this helps!!

Yes they are but I don't feel like explaining!
