Comprehension
The right to clean and healthy environment has been recognized as a fundamental right under Article 21 of the Constitution of India. Article 48-A imposes a duty upon the State to endeavour to protect and improve the environment and safeguard the forests and wildlife of the Country. In addition to this, India is also a party to international treaties, agreements and conferences and has committed itself to sustainable development and growth. This legal framework indicates that sustainable development must remain at the heart of any development policy implemented by the state. It is essential to strike the right balance between environmental conservation and protection on one hand, and the right to development on the other, while articulating the doctrine of sustainable development. We may add that in our opinion conservation and development need not be viewed as binaries, but as complementary strategies that weave into one another. In other words, conservation of nature must be viewed as part of development and not as a factor stultifying development.

The Correct Option is B

Approach Solution - 1

The fundamental duty to protect and improve the natural environment is enshrined in the Constitution of India under Article 51A(g). This provision specifically mandates that it is the duty of every citizen of India to protect and improve the natural environment, including forests, lakes, rivers, and wildlife, and to have compassion for living creatures.

Here is a breakdown of the relevant provisions:

ProvisionFundamental Duty
51A(h)To develop the scientific temper, humanism and the spirit of inquiry and reform
51A(g)To protect and improve the natural environment including forests, lakes, rivers and wildlife, and to have compassion for living creatures
51A(f)To value and preserve the rich heritage of our composite culture
51A(d)To defend the country and render national service when called upon to do so

The comprehension provided emphasizes the right to a clean and healthy environment recognized under Article 21 and the state's duty under Article 48-A to protect the environment, underscoring the importance of sustainable development in both national policy and international commitments. The goal is to reconcile environmental conservation with development, treating them as complementary rather than opposing goals.

Approach Solution -2

The question asks which clause of Article 51A contains the fundamental duty to protect and improve the natural environment.

  1. Option A: "51A(h)" concerns developing scientific temper, humanism, and the spirit of inquiry and reform, an important duty but unrelated to the environment.
  2. Option B: "51A(g)" is the clause that expressly casts a duty on every citizen to protect and improve the natural environment, including forests, lakes, rivers, and wildlife, and to have compassion for living creatures, which is exactly what the question asks about.
  3. Option C: "51A(f)" concerns valuing and preserving the rich heritage of India's composite culture, a cultural duty rather than an environmental one.
  4. Option D: "51A(d)" concerns defending the country and rendering national service when called upon, unrelated to environmental protection.

Matching the subject matter of the duty described in the question to the actual text of each clause leaves only one that fits.

Hence, the correct answer is "51A(g)."

Question: 2

Under which of the following provisions can Union legislature enact laws for giving effect to international agreements?

The Correct Option is C

Approach Solution - 1

To determine under which provision the Union Legislature can enact laws for giving effect to international agreements, we refer to the Indian Constitution:

  • Article 253 - This article empowers the Parliament to make any law for the whole or any part of the territory of India for implementing any treaty, agreement, or convention with any other country or countries or any decision made at any international conference, association, or other body. It essentially gives the Union Government the authority to fulfill its international obligations by enacting appropriate legislation.
  • By contrast, the other articles mentioned are related to different aspects:
    • Article 251 - Related to inconsistency between laws made by Parliament and laws made by the legislatures of States.
    • Article 252 - Provides for the power to legislate for two or more states by consent and adoption of such legislation by any other State.
    • Article 254 - Deals with inconsistency between laws made by Parliament and laws made by the legislatures of States, and resolves such inconsistencies.

In conclusion, Article 253 is the correct provision under which the Union Legislature can enact laws for giving effect to international agreements.

Approach Solution -2

This question asks which constitutional provision empowers Parliament to legislate for implementing India's international obligations. The four options are all provisions found in Part XI of the Constitution dealing with legislative relations between the Union and the States, so each needs to be checked against what it actually does.

  1. Article 251: This provision deals with what happens when a law made by Parliament under Articles 249 or 250 (during a national emergency or when the Rajya Sabha declares a matter to be of national importance) is inconsistent with a State law. It resolves a conflict of laws, it does not create any new subject on which Parliament can legislate to give effect to a treaty, so it does not answer the question.
  2. Article 252: This allows Parliament to legislate on a State subject only when two or more State legislatures pass resolutions consenting to such legislation, and that law then applies only to the consenting States unless others adopt it later. It is a consent-based mechanism between States and Parliament, unconnected to international agreements, so it can be ruled out.
  3. Article 253: This is the specific provision that lets Parliament make law for the whole or any part of India for implementing any treaty, agreement, or convention with another country, or any decision of an international conference, association, or body. Unlike Article 252, no consent of the States is needed here, because giving effect to international commitments is treated as a Union responsibility. This directly matches the situation described in the question.
  4. Article 254: This provision resolves repugnancy between a Union law and a State law on a Concurrent List subject, deciding which law prevails. It has nothing to do with treaty implementation.

Only Article 253 gives Parliament the specific power to enact laws for implementing international treaties and agreements, independent of any State consent, which is exactly what the question describes.

Hence the correct answer is Article 253.

Question: 3

By which of the following Constitution Amendment Act were Entries 17A and 17B inserted in List III of the Seventh Schedule of the Constitution of India?

Updated On: Jul 10, 2026
  • Constitution (Fortieth Amendment) Act, 1976

The Correct Option is B

Approach Solution - 1

The Constitution (Forty Second Amendment) Act, 1976 inserted Entries 17A and 17B into List III of the Seventh Schedule of the Constitution of India. This amendment, known as the "mini-constitution," was significant as it addressed multiple aspects of governance and legal structures in India. Entries 17A and 17B specifically dealt with 'Forests' and 'Protection of Wild Animals and Birds,' respectively. This inclusion aligns with India's commitment to sustainable development as part of its constitutional duties as enshrined in Article 48-A, which obligates the state to protect and improve the environment and safeguard wildlife. Thus, these entries reinforce the legal framework to ensure environmental conservation is integrated with developmental policies.

The question is about identifying which Constitutional Amendment Act moved the subjects of environment protection into the Concurrent List. Each option can be checked by what that particular amendment is actually known for.

  1. Constitution (Fortieth Amendment) Act, 1976: This amendment mainly dealt with vesting mineral and other resources of the territorial waters and continental shelf in the Union, and validated certain existing Acts by placing them in the Ninth Schedule. It has no connection with Entries 17A or 17B.
  2. Constitution (Forty Second Amendment) Act, 1976: Passed during the Emergency, this is one of the widest-ranging amendments ever made to the Constitution. Among its many changes, it added Forests and Protection of wild animals and birds as Entries 17A and 17B respectively to List III, the Concurrent List, of the Seventh Schedule, shifting these subjects from exclusive State control to shared Union-State legislative competence. It also inserted Article 48-A, the Directive Principle on environment, and Article 51A(g), the fundamental duty regarding environment, in the same exercise, showing a consistent environmental thrust in this particular amendment.
  3. Constitution (Forty Fourth Amendment) Act, 1978: This amendment is chiefly remembered for reversing several Emergency-era changes made by the 42nd Amendment, such as removing the right to property as a fundamental right and restoring safeguards around the proclamation of Emergency. It did not touch the Seventh Schedule entries on forests or wildlife.
  4. Constitution (Forty Sixth Amendment) Act, 1982: This amendment is associated with sales tax matters, particularly widening the definition of tax on sale or purchase of goods to cover works contracts, hire-purchase, and similar transactions. It is unrelated to the Seventh Schedule's environmental entries.

Only the Forty Second Amendment Act, 1976 matches both the timing and the substantive changes described, since it is the amendment that inserted Entries 17A and 17B into the Concurrent List alongside the broader environmental provisions of Articles 48-A and 51A(g).

Therefore, the correct answer is Constitution (Forty Second Amendment) Act, 1976.

The Correct Option is C

Approach Solution - 1

The question asks which judgment does not address sustainable development. Among the options provided, we have:
  • Karnataka Industrial Area Development Board v. C. Kenchappa, (2006) 6 SCC 371.
  • Tata Housing Development Co. Ltd. v. Aalok Jagga, (2020) 15 SCC 784.
  • Manorama Sachan v. Lucknow Development Authority, (2005) 9 SCC 425.
  • Maharashtra Land Development Corporation v. State of Maharashtra, (2011) 15 SCC 616.
The legal concept of sustainable development involves integrating the need for environmental conservation with developmental activities. In the context of the provided options:
Karnataka Industrial Area Development Board v. C. Kenchappa deals with sustainable development as it addresses the balance between industrial development and environmental rights in line with Article 21 and Article 48-A of the Indian Constitution.
Tata Housing Development Co. Ltd. v. Aalok Jagga also engages with issues of development aligned with sustainable environmental practices.
Maharashtra Land Development Corporation v. State of Maharashtra involves aspects of land use policy, which often encompasses sustainable development considerations.
However, Manorama Sachan v. Lucknow Development Authority does not directly relate to sustainable development. This case primarily addresses issues of urban development without the explicit emphasis on sustainable development as seen in the others.
  • Therefore, the correct answer is: Manorama Sachan v. Lucknow Development Authority, (2005) 9 SCC 425.

Approach Solution -2

This question requires identifying the odd one out among four case citations, three of which involve the doctrine of sustainable development and one of which does not. The best approach is to look at what each case actually decided rather than just its name.

  1. Karnataka Industrial Area Development Board v. C. Kenchappa, (2006) 6 SCC 371: This case dealt with land acquisition for industrial development and directly discussed balancing industrial growth against ecological protection, applying the sustainable development principle and the precautionary principle to safeguard agricultural land and water bodies near the acquired area. This case is about sustainable development.
  2. Tata Housing Development Co. Ltd. v. Aalok Jagga, (2020) 15 SCC 784: This case concerned construction and housing development in ecologically sensitive areas near a lake catchment, and the Supreme Court's reasoning turned on environmental clearances and the need to reconcile development with ecological preservation, again a sustainable development case.
  3. Manorama Sachan v. Lucknow Development Authority, (2005) 9 SCC 425: This case is essentially a service and administrative law matter concerning irregularities in an appointment made by the Lucknow Development Authority, and it does not engage with environmental protection, ecological balance, or the sustainable development doctrine at all. Its subject matter is entirely different from the other three options.
  4. Maharashtra Land Development Corporation v. State of Maharashtra, (2011) 15 SCC 616: This case involves land development permissions and touches upon regulatory conditions for development activity, which courts have historically tied to the sustainable development framework when balancing growth against environmental regulation.

Three of the four citations, Karnataka Industrial Area Development Board, Tata Housing Development, and Maharashtra Land Development Corporation, all involve courts weighing development against environmental protection. Manorama Sachan v. Lucknow Development Authority stands apart because it is a service law dispute unconnected to environmental jurisprudence.

Hence, the correct answer is Manorama Sachan v. Lucknow Development Authority, (2005) 9 SCC 425.

Question: 5

Which of the following depicts the most appropriate response regarding Public Trust Doctrine?

Updated On: Jul 10, 2026
  • That resources like sea, waters, forests are extremely important to the masses and therefore it would be unjustified to make them subjects of private ownership.
  • The people of the country have a fundamental duty to protect the environment.
  • Right to clean environment is a fundamental right.
  • All of the above.
Show Solution

Verified By Collegedunia

The Correct Option is A

Approach Solution - 1

The Public Trust Doctrine is a legal principle emphasizing that natural resources like the sea, waters, and forests are too essential for the general public to be subjected to private ownership. This doctrine suggests that the government should hold these resources in trust for public use and enjoyment, ensuring their protection and maintenance for future generations. This makes the correct response to focus on the idea that:

"That resources like sea, waters, forests are extremely important to the masses and therefore it would be unjustified to make them subjects of private ownership."

Under this doctrine, these resources are meant to be preserved and remain available for public use rather than being exploited for individual benefit, aligning with the principles of sustainable development and environmental conservation as highlighted in Indian constitutional provisions and international commitments.

Approach Solution -2

The question asks for the most accurate description of the Public Trust Doctrine, and the safest way to answer this is to test each option against what the doctrine actually holds, since two of the four options describe entirely different legal principles that happen to be grouped together in the fourth option.

  1. Option 1: This option states that resources such as the sea, waters and forests are too important to the general public to be made subjects of private ownership. This is the precise core of the Public Trust Doctrine as recognised in Indian law since M.C. Mehta v. Kamal Nath, where the Supreme Court held that certain natural resources are held by the State as a trustee for public use and cannot be diverted to purely private, commercial ends. This statement correctly captures the doctrine.
  2. Option 2: This option describes the fundamental duty of citizens to protect the environment. That is a distinct constitutional obligation found in Article 51A(g), which speaks to individual conduct rather than to the State's trusteeship over natural resources. It does not describe the Public Trust Doctrine itself.
  3. Option 3: This option asserts that the right to a clean environment is a fundamental right. That principle flows from the expansive reading of Article 21, the right to life, in cases such as Subhash Kumar v. State of Bihar, and while it is related to environmental jurisprudence generally, it is a separate doctrine about individual rights, not about the nature of public trusteeship over resources.
  4. Option 4: This groups all three statements together as correct. Since Options 2 and 3 describe separate legal principles, fundamental duty and fundamental right respectively, rather than the Public Trust Doctrine, this option overstates what the doctrine covers.

Only the first option describes the actual content of the Public Trust Doctrine, that certain resources are inherently public in character and cannot lawfully be reduced to private ownership.

Therefore, the correct answer is that resources like sea, waters, forests are extremely important to the masses and therefore it would be unjustified to make them subjects of private ownership.

Question: 6

Which of the following doctrines is/are part of environmental jurisprudence in India?

Verified By Collegedunia

The Correct Option is C

Approach Solution - 1

The question pertains to the doctrines that form part of environmental jurisprudence in India. Let's evaluate each option to determine which are applicable:

  • Polluter Pays Principle: This principle mandates that those who produce pollution should bear the costs of managing it to prevent damage to human health or the environment. It is widely recognized and applied in Indian environmental law.
  • Precautionary Principle: This principle is a proactive measure to protect the environment when there is a lack of full scientific certainty. It encourages preventive action in the face of uncertainty and is also an integral part of environmental law in India.
  • Sovereign Immunity Principle: The Sovereign Immunity Principle is not typically recognized as part of environmental jurisprudence in India. It refers to the doctrine that the state cannot commit a legal wrong and is immune from civil suit or criminal prosecution.

Given these explanations, both the Polluter Pays Principle and the Precautionary Principle are part of the environmental jurisprudence in India.

Correct Answer: Both (A) and (B)

Approach Solution -2

This question tests whether specific doctrines are recognised as part of India's environmental jurisprudence. Each doctrine named in the options needs to be checked individually before combining them.

  1. Polluter Pays Principle: This principle, that the polluter is liable to pay for the cost of environmental damage and restoration, was expressly adopted by the Supreme Court in Indian Council for Enviro-Legal Action v. Union of India and Vellore Citizens' Welfare Forum v. Union of India, making it a settled part of Indian environmental jurisprudence.
  2. Precautionary Principle: This principle, that the absence of full scientific certainty should not be used to postpone measures preventing environmental harm, was also recognised as part of Indian law in the Vellore Citizens' case, placing the burden on the developer to show that its action is environmentally benign.
  3. Both (A) and (B): Since both the Polluter Pays Principle and the Precautionary Principle are independently confirmed as recognised doctrines in Indian environmental law by the same line of Supreme Court judgments, this combined option correctly reflects that both are part of the jurisprudence.
  4. Sovereign Immunity Principle: This is an entirely different doctrine from public law, concerning the State's traditional immunity from being sued for acts done in exercise of sovereign functions. It is not treated as a doctrine of environmental jurisprudence, and Indian courts have generally been reluctant to allow sovereign immunity as a defence in environmental damage cases, since environmental protection duties run directly against the State under Article 21 and Article 48-A.

Since both the Polluter Pays Principle and the Precautionary Principle are established doctrines in Indian environmental jurisprudence, while the Sovereign Immunity Principle is unrelated and even works against environmental accountability, the combined option is the accurate one.

Hence, the correct answer is Both (A) and (B).
