What is the 'doctrine of election' as enunciated under the Transfer of Property Act, 1882?

Section 35 of the Transfer of Property Act deals with what is called doctrine of election. Suppose, a property is given to you and in the same deed of gift you are asked to transfer something belonging to you to another person. If you want to take the property you should transfer your property to someone else, otherwise you cannot take the property which is transferred to you by some one. Election may be defined as "the choosing between two rights where there is a clear intention that both were not intended to be enjoyed". The foundation of doctrine of election is that a person taking the benefit of an instrument must also bear the burden, and he must not take under and against the same instrument. It is, therefore, a branch of a general rule that no one may approbate and reprobate [ Copper v. Copper (1874) H.L. 53 ]. However doctrine of election could not be applied to deprive a person of his statutory right to appear invoking extraordinary jurisdiction of the Supreme Court under Article 136, [ PR Deshpande v. MB Haribatti (1995 (2) Scale 804 SC) ].
