S. 3(2) and S. 32(2) - Kya Difference Hai?

Tum log mock tests dete ho, mera shift hai! Maine dono sections ko padha hai, lekin koi sense nahi aata. Difference kya hai S. 3(2) ko S. 32(2) se? S. 3(2) mein kaha hai ki "Burden of Proving" hamesha plaintiff par hi hota hai, chaahe evidence direct ya circumstantial ho.

Lekin S. 32(2) mein kaha hai ki burden of proof direct evidence ke liye hamesha plaintiff par hi hota hai, lekin circumstantial evidence ke liye defendant par shift kar deta hai. Aisa lagta hai ki S. 32(2) mein relaxation hai, phir kyun?
