Kya IPC aur BNS dono hi samaan baat karte hain?

Main IPC (Indian Penal Code) ka concept of 'Act of God' aur BNS (British North Western System) ke under 'Actum Dei' ka saman kaun sa hota hai? To, hum IPC ke under, kisi accident ka saboot mang rahe hain, lekin abhi tak aapke paas koi gawaahi nahin, toh FIR lagva di. Ab aapko apne defense mein yeh karna padta hai ki 'Act of God' se wahi hua tha. Isi tarah, BNS ke under 'Actum Dei' wahi hai. Lekin main samajh nahi pa raha ki kya yah dono hi ek hi cheez hi hoti hai ya phir ek doosre se alag? Please help.
