Relevant Evidence vs Relevant Facts under Evidence Act

Yaar samajh nahi aaya, please help! Abhi exam mein padh rha hoon, to ek concept ki confusion chhod nahi rhi hai. Relevant evidence aur relevant facts dono hi kai baar evidence act mein use hote hein, lekin fir bhi ek jatilta hai.

Mujhe lagta hai ki dono hi ek dusre ki jagah use hote hein. Jo bhi shahadat relevant evidence ke under aa rhi hai, voh hi shahadat relevant facts ke under bhi aapni hogi? Toh phir kyun kaha jata hai ki relevant evidence aur relevant facts dono hi alag alag hai. Toh kya difference hai dono ke beech?

Koi sahi kya jata hai? Jald se jald batao, please!
