Kya contract vikalp hai aur administrative law mein contract vikalp ka upyog kaise hota hai?

Maine socha tha contract koi bhi vyavsaay ko pehle se nirdharit sharton ke saath karna hai, lekin abhi yeh samajh nahi a raha ki kyu yeh contract vikalp administrative law mein upyog kiya jaata hai. Kya yeh yehi hota hai ki vyavsaay nirdharit hote hue, government aur corporate sector ko bhi contract banane ka adhikar milega aur wo bhi kisi vyavsaay ke saath?
