Kya Hua? Witness Statement Par Difference Ho Gaya

Main aur mera dost, Rohan CLAT ka paper dene ja rahe hai. Hum Evidence Act ka Section 18 dekh rahe the. Pata lag gaya ki hamare beech ek sawal par difference ho gaya. Rohan keh raha hai ki Section 18 ke under witness ko phati hui jaankari ya aadmi kee jaankari ko sunane ke liye aazad hain. Lekin main keh raha hoon ki Section 20 ke under bhi phati hui jaankaari ki sunne ke liye aazad hain. Ab hum dono confused ho gaye hain. Kya karen? Kya unki baat sahi hai ya main ki? Aap log sochke dikhaye!
