CrPC ka Ek Chhota Secret

Maine ek internship pehli baar court visit kiya tha, jaha par judge ne 138 CrPC ka mention kiya jab ek witnesses ki statement sunayi gayi thi. Pehli baar suna ki 138 CrPC ka matlab yeh hai ki agar koi witness statement sunane ke liye nahi aaya to police ko uska declaration le jana chaahiye hai. Maine ye question 3 baar padha aur abhi bhi samajh nahi aaya 😭. Lekin phir maine socha ki abhi tak maine ye chapter padha hi nahi hai. Yeh toh mere textbook mein nahi tha, lekin ab maine padha hai aur samajh gaya hai. Kya aap logon ne 138 CrPC ka abhi tak mention nahi kiya tha?
