Identify the foundational legal precedent established by the Supreme Court in the 1951 State of Madras v. Champakam Dorairajan judgment:
1. The judgment established that the overarching framework of the Republic relies on an unalterable bedrock of balance between Part III and Part IV.
2. The judgment decreed that in any direct legislative conflict, the Directive Principles inherently possess a position of legal primacy over Fundamental Rights.
3. The judgment mandated that the Directive Principles must structurally conform to and operate as entirely subsidiary to the Fundamental Rights.
