Section 32 of Evidence Act - Kaun Se Rule Hai?

Maine socha hai ki Section 32 ka matlab yehi hai ki ek witness ko pehle se pahle court mein sawal puchne se pehle, unki jaankari ko confirm karne ke liye ek affidavit ya affidavit-like document banvana hoga. Lekin kuch log kheenchte hain ki yeh rule sirf jo witnesses hai jo kuch crime scene ya evidence dekhne ke baad aaye hain, unhone kya jaankari li hai. Lekin kya yeh sirf crime-related witnesses ke liye hai ya kisi bhi witness ke liye?
