IPC ka Baap ya BNS ka Bada Bhai?

Main toh yeh kahunga ki IPC ka Baap hai, kyonki ismein crime ki definitions aur punishments toh di gayi hain, lekin BNS mein yeh sabh kiya hai ki IPC ka application kahan hai, yeh samjhauta kiya hai. BNS isliye bhi important hai kyunki yeh IPC ki interpretation ko decide karta hai. Lekin agar mujhe ask karna hai to IPC toh sabse bada aadmi hai. BNS toh iske chachu ki tarah hai, bhai ka bhai. IPC ke bare mein kya sochte hai aap log? IPC ko apne liye kyun lete hain?
