(1) The testator may direct that a legacy be granted in such a way that the person provided for is only to receive one or the other of more than one object. If in such a case the choice is transferred to a third person, it is made by declaration to the person charged.
(2) If the third person is unable to make the choice, the right to choose devolves to the person charged. The provision of section 2151 (3) sentence 2 applies accordingly.
