Mangal Prasad v Kedar Prasad: A Landmark Case on TPA?

This case is from 1915, so you'd think it's old news, but trust me, it's still relevant today. Mangal Prasad v Kedar Prasad (1915 PC 133) is a Privy Council case that laid down the law on the Transfer of Property Act (TPA). The question was whether a gift deed could be revoked by a subsequent will. The answer was a big fat NO. The court held that a gift deed is a present transfer of ownership and cannot be revoked by a will, which is a future transfer. This judgment still stands today, and it's a key point to remember for AILET aspirants. What do you guys think? Is the judgment outdated or still relevant in today's property law scenario?
