Kya Hai Rule of Necessity?

Maine ek memory trick banaya jo mere liye Administrative Law ka sabse bada challenge tha, yeh sab ke andar rule of necessity hai. Main ek shayari likhungi "Necessity is the mother of law, aur flexibility is its dada". Yeh shayari maine banayi hai ki main aashayein rakho ki koi bhi rule bina necessity ke niyam ke aapke liye sabse bura ho sakta hai. Lekin isse isliye zaroorat hoti hai jab court ko lagta hai ki kuch bhi karna hoga aur woh rule of law se bhi bahe ja raha hai. Toh main iss memory trick ko use karke sab se bada relief mil gaya tha.
