Explanation:

1. 42^nd Amendment Act accorded the position of legal primacy and supremacy to the Directive Principles over the Fundamental Rights conferred by Articles 14, 19 and 31. However, this extension was declared as unconstitutional and invalid by the Supreme Court in the Minerva Mills case (1980).
2. It means that the Directive Principles were once again made subordinate to the Fundamental Rights. But the Fundamental Rights conferred by Article 14 and Article 19 were accepted as subordinate to the Directive Principles specified in Article 39 (b) and (c). Further, Article 31 (right to property) was abolished by the 44th Amendment Act (1978).
3. In the Minerva Mills case (1980), the Supreme Court also held that ‘the Indian Constitution is founded on the bedrock of the balance between the Fundamental Rights and the Directive Principles.
