UPSC Geo‑Scientist – General Awareness & Current Affairs
Topic: Constitution
Goal: Understand the Constitution as a living document that shapes the legal and scientific framework of India, especially for fields like geography, geology, and environmental science.
1. Simple Explanation
The Constitution of India is the supreme law of the land. It lays down the framework for the governance of the country, defines the powers of the three branches of government, and guarantees fundamental rights and duties to its citizens. It is a written, codified, and supreme constitution, meaning that any law or executive action that conflicts with it is void.
Why it matters for Geo‑Scientists:
- The Constitution provides the legal authority for environmental legislation (e.g., the Environment Protection Act, Forest Act).
- It establishes the structure of scientific advisory bodies (e.g., Indian Space Research Organisation (ISRO) oversight).
- It sets the basis for resource‑related policies (water, minerals, land use).
2. Key Points
| Category | Highlights | Why It’s Important |
|---|---|---|
| Definition & Nature | • Written, codified, supreme, and flexible (amendable). | Provides the foundational legal framework for all scientific and policy decisions. |
| Structure | • Preamble (values). • Parts (I–XVII). • Schedules (1–12). • Amendments. |

| Amendment Process | • Article 368 – two‑step process: 1. Drafting & Parliamentary approval (2/3 majority in both houses). 2. Optional State Ratification (for certain changes). |
42nd & 73rd Amendments exemplify the procedure. |

| 91st Amendment (2003) | • Added Directive Principles on environment and sustainable development. | Reinforced environmental conservation as a national priority. |
| Judicial Interpretations | • Kesavananda Bharati v. State of Kerala (1973) – Basic Structure doctrine. • S.R. Bommai v. Union of India (1994) – limits on President’s power to dismiss state governments. • V. C. Shankar v. State of Karnataka (2020) – protected environmental rights. |
These judgments shape how laws are applied to scientific and environmental matters. |
| Environmental Laws Derived from Constitution | • Environment (Protection) Act, 1986 – Article 21 & 25. • Forest (Conservation) Act, 1980 – Article 48A (Directive Principles). • Water (Prevention & Control of Pollution) Act, 1974 – Article 21. • National Green Tribunal – established under Article 21. |
