BSA ka Bhai, kuch nahi samajh raha

Main 3 din ke exam ke baad hoon, aur fir bhi main evidence act mein BSA se pehle se problemat hoon. Bas ek cheez hai, main samajh nahin pa raha. Humein yeh samjhna hai ki kab he witness ko witness ko cross examination ke liye call kiya ja sakta hai, aur kab nahin. Main sochta hoon ki ye toh kai section 280, 281, aur 284 mein di gayi shartaon se juda hua hai, lekin main kaise samajh sakta hoon ki kab cross examination ka adhikar hota hai aur kaise cross examination ke dauran is shart ka dhyan rakhna hoga...
