Void Agreement ka Kya Hota Hai?

Maine contract law mein ek sawal ka jawab laga raha hoon. Pehla option yeh hai: A contract jo ki unmannya (unreasonably) adhik dainik ratis (exorbitant rate) par chunauti jata hai woh void hai. Ab yeh socha hai ki kya yeh sach hai. Kya ek contract jo ki adhik ratis par chunauti jata hai use hi khara nahi kiya ja sakta?

Aur dusra option yeh hai: Agar contract mein koi khilafat (unfair provisions) hai to usko void mana jata hai. To kya hum adhik ratis ka hi ek khilafat ka shreni samjha sakte hain?
