In Gartside v Commissioners of Inland Revenue[1967] UKHL 6, [1968] AC 553 (13 December 1967), House of Lords (UK) it was argued that because a beneficiary might receive all the income, he should be treated as being entitled to all of the income, however, the House of Lords held that it could not be said that any individual beneficiary under a discretionary trust was entitled to any quantifiable share.
