Tagore v. Tagore laid down which one of the following rules of law?

In Tagore v. Tagore (1872) the Privy Council held that a Hindu cannot make a gift in favour of a person not in existence at the date of the gift, so a Hindu cannot dispose of his property "by gift inter vivos in favour of an unborn child". The case did not deal with the karta's powers, the reopening of a partition or the adoption of orphans. The rule was later relaxed by statute, notably the Hindu Disposition of Property Act, 1916.
