The statement about the synthesis between 'Fundamental Rights' and 'Directive Principles of State Policy' is drawn from the judgment Maneka Gandhi v. Union of India (1978) 1 SCC 248.
This case is a landmark decision in Indian constitutional law where the Supreme Court expanded the interpretation of the term 'personal liberty' in Article 21 of the Indian Constitution. It emphasized the harmony and balance between Fundamental Rights and Directive Principles, suggesting that both are integral to achieving the goals set forth by the Constitution.
The court highlighted that while Fundamental Rights are primary, Directive Principles have an enduring role in guiding state policy, thus deserving a place of permanence. This interpretation marked a significant development in ensuring that neither are viewed in isolation but as complementary to each other, embodying the 'true conscience' of the Constitution.
