s 158 Validation of appointments where objects are excluded or take illusory shares.
(1) No appointment made in exercise of any power to appoint any property among two or more objects shall be invalid on the ground that— (a) an unsubstantial, illusory, or nominal share only is appointed to or left unappointed to devolve upon any one or more of the objects of the power; or (b) any object of the power is thereby altogether excluded; but every such appointment shall be valid notwithstanding that any one or more of the objects is not thereby, or in default of appointment, to take any share in the property. (2) This section does not affect any provision in the instrument creating the power which declares the amount of any share from which any object of the power is not to be excluded. (3) This section applies to appointments made before or after the commencement of this Act.
