The basic structure doctrine is a common law legal doctrine that the constitution of a sovereign state has certain characteristics that cannot be erased by its legislature. The doctrine is recognised in India, Bangladesh, Malaysia, Pakistan, and Uganda. It was developed by the Supreme Court of India in a series of constitutional law cases in the 1960s and 1970s that culminated in Kesavananda Bharati v. State of Kerala, where the doctrine was formally adopted. Bangladesh is perhaps the only legal system in the world which recognizes this doctrine with an expressed, written and rigid constitutional manner through article 7B of its Constitution. In Kesavananda, Justice Hans Raj Khanna propounded that the Constitution of India has certain basic features that cannot be altered or destroyed through amendments by the Parliament of India. Key among these "basic features", as expounded by Justice Khanna, are the fundamental rights guaranteed to individuals by the constitution. The doctrine thus forms the basis of the power of the Supreme Court of India to review and strike down constitutional amendments and acts enacted by the Parliament which conflict with or seek to alter this "basic structure" of the Constitution. The basic features of the Constitution have not been explicitly defined by the Judiciary, and the claim of any particular feature of the Constitution to be a "basic" feature is determined by the Court in each case that comes before it. The Supreme Court's initial position on constitutional amendments had been that any part of the Constitution was amendable and that the Parliament might, by passing a Constitution Amendment Act in compliance with the requirements of article 368, amend any provision of the Constitution, including the Fundamental Rights and article 368. In 1967, the Supreme Court reversed its earlier decisions in Golaknath v. State of Punjab. It held that Fundamental Rights included in Part III of the Constitution are given a "transcendental position" and are beyond the reach of Parliament. It also declared any amendment that "takes away or abridges" a Fundamental Right conferred by Part III as unconstitutional. In 1973, the basic structure doctrine was formally introduced with rigorous legal reasoning in Justice Hans Raj Khanna's decisive judgment in the landmark decision of Kesavananda Bharati v. State of Kerala. Previously, the Supreme Court had held that the power of Parliament to amend the Constitution was unfettered. However, in this landmark ruling, the Court adjudicated that while Parliament
