Kelsen vs Austin: Kya Hai Right?

Maine aur my friend Pawan ke liye ek MCQ banaya hai AILET ke liye. Woh bata rha hai ki Kelsen ka idea of right (rechtsstat) woh right hai jo court ke rules ke under accepted hai, kya? Lekin main keh rha hu ki Kelsen ka idea of right is a moral standard jiski validation hamesha ke liye applicable hai, yeh right to be in constitution.

Example: Article 14 ka sabse chota right hai equality. Maine Pawan se poocha kyun? Kya Constitution mein jo bhi kuch likha hai, voh sab ke liye applicable hai ya sirf court ke rules ke under?
