Best deployed in GS1 geography and GS2 international relations with the India-Bangladesh settlement as the worked example. The Constitution (One Hundredth Amendment) Act, 2015, dated 28 May 2015, gave effect to the Land Boundary Agreement of 1974 and its 2011 Protocol; India transferred 111 enclaves to Bangladesh and received 51, with the exchange taking effect on 31 July 2015. That single sentence, dated, is worth more than a paragraph of general description.
