Section 375 IPC: Abetment by Person Justifying Act

Kya yeh case bahut tricky tha? Question theek se theeka tha, lekin logic kuchh ghata tha. Case: Pita ne apne bete ko 10 years se pahle hi sex karne ka mauka diya tha. Uske baad, jab bete ne kisi andar ke shiksha grih ki student ko sex karne ka kadam uthaya, to pita ne police ko phone karke bataya. Lekin, ab Pita ko abetment of rape ke liye trial karna hoga ya nahin? Kya pita apne bete ko sex karne ka mauka diya to woh abetment of rape nahin hoga?
