Neighbourhood Relations — Policy Changes

Entry	Year	Description	Impact
100th Amendment	2015	Enabled the India-Bangladesh Land Boundary Agreement implementation by allowing exchange of enclaves and adverse possessions. This constitutional amendment was necessary following the Berubari Union case precedent requiring constitutional ratification for territorial changes.	Resolved the world's most complex border demarcation issue, eliminated 162 enclaves, and demonstrated India's commitment to peaceful boundary settlement with neighbours, serving as a model for other territorial disputes.
9th Amendment	1960	Transferred Berubari Union territory to Pakistan as part of boundary settlement, establishing the constitutional precedent that territorial cession requires constitutional amendment rather than mere executive action.	Created the constitutional framework for all future boundary agreements with neighbours, ensuring parliamentary oversight and democratic legitimacy for territorial changes while limiting executive discretion in sovereignty matters.
