Tortious Interference vs Unlawful Means - Kaun Sa Hai?

Doston, ek question aaya hai jo mujhe bahut confuse kar raha hai. Maine kuchh days pehle Contract paper dekh kar realize kiya ki Tort ke concepts main bhi samajhna zaroori hai. Lekin, Tortious Interference vs Unlawful Means ke beech ki difference pe main samajh nahi paya. Main socha tha ki dono hi kuchch hee same hain, magar aisa lagta hai ki kuchch aur hain. Kya Tortious Interference ka matlab hai ki jo interference hi keval tort ke liye hoga, aur Unlawful Means ka matlab hai ki wahan keval tareeka galat hona chaahiye? Kya yeh dwaaraa hi hain? Bataiye log.
