CPC 144, 145 aur 177 khaas hai kya?

Maine apne notes aur class notes dekhe hain, par yeh section mera dimag par nahin aaraaha hai. CPC 144 wala 'wrongful restraint' aur 145 wala 'wrongful confinement' hi to 144 ka hi ek extension hai, toh phir 177 ki zaroorat kyun hai? Main samajh nahin pa raha hoon ke CPC 144 wala offense jo zimmewar ke khilaaf hai, use 177 nazar andaza karta hai. Kya 177 ka purpose aapke paas pata hai? Kya ye do alag-alag offenses hain, ya phir yeh 144 ka hi ek extension hai jiski koi aur definition hai?
