Explanation:

Let’s break this down:

- When a higher court decides something, lower courts have to follow that decision. This is called precedent. The lower courts can’t just ignore or distort what’s been set above them.

- Here’s what each option actually means:

- Salus Populi Est Suprema Lex: The welfare of the people shall be the supreme law. Not about precedents—more about public good.

-  Stare Decisis: Stand by things decided. This is the exact principle that binds lower courts to follow higher court rulings. This is the answer.

- Ubi Jus Ibi Remedium: Where there is a right, there is a remedy. That’s legal protection, not court hierarchy.

- Quid Pro Quo: Something for something. Nothing to do with precedent or binding decisions.

- So, out of all these, Stare Decisis is the maxim you want.
