The concept of officers of the court and the right to practice law

No attorney in the U.S. is allowed to practice law without first being sworn in as an "officer of the court".

Yet, all State Constitutions prohibit judges - "officers of the court" - to practice law.

So, the practice of law is conditioned in the U.S. upon joining a class of people who, by State Constitutions, are prohibited to practice law.

And, the rule for lawyers to be "officers of the court" (who are not allowed to practice law) in order to be able to practice law was concocted by lawyers themselves, who are the best experts in the practice of law.

Mamma mia.
