AIBE 21 Most Important Topics on Law Cases

 

The preparation approach for AIBE 21 has changed significantly in recent years. Earlier, candidates could rely mainly on bare acts, but now the exam demands a deeper understanding of case laws, doctrines, and legal concepts. 

From AIBE 20 onwards, questions are more analytical and concept-based, making it essential to study landmark Supreme Court judgments. Reviewing Previous Year Questions (PYQs) from AIBE 14 to AIBE 20 helps in identifying important trends and frequently asked topics.

To succeed, candidates must follow an updated AIBE examination strategy that combines theory with case law application.

AIBE Examination Strategy Evolution

The AIBE 21 examination strategy differs significantly from AIBE 19, aligning more with AIBE 20. Previously, the primary focus was on bare act knowledge. However, the Current Strategy (AIBE 20 onwards) requires a broader approach, including Case Laws, Doctrines, and Concepts. 

Skipping these areas can lead to examination failure. This session analyzes AIBE Previous Year Questions (PYQs) on case laws from AIBE 14 to AIBE 20, building on earlier discussions of landmark cases.

Case Law Important Topics from AIBE PYQs

Understanding landmark judgments is crucial, as many questions are directly or indirectly based on them. Below are the most important case laws frequently asked in AIBE exams.

1. Anuradha Bhasin v. Union of India (January 10, 2020)

This case relates to a challenge under Article 32 of the Constitution, seeking an appropriate writ for setting aside government orders that shut down all modes of communication, including the internet. The judgment established that the Right to Internet is a part of fundamental rights.

2. In Re: Berubari Union (1960)

The Berubari case, from 1960, is important when studying the evolution of constitutional interpretation, particularly concerning the Preamble. This case was later overruled by Kesavananda Bharati v. State of Kerala.

Feature

Berubari Case (1960)

Kesavananda Bharati Case

Preamble Status

Held that the Preamble is NOT a part of the Constitution.

Overruled Berubari judgment, stating the Preamble IS a part of the Constitution.

3. Maneka Gandhi v. Union of India

This leading decision is strongly associated with the Right to Travel and significantly widened the narrow interpretation of Article 21. It established the linkage between Article 14, Article 19, and Article 21, emphasizing how they form the "holy trinity" of the Indian Constitution. The case also discussed the concept of Due Process of Law and the inclusion of the right to live with human dignity within the Right to Life.

4. Invocation of Transformative Constitutionalism

The Supreme Court invoked the principle of Transformative Constitutionalism in the case of Navtej Singh Johar v. Union of India. This concept involves the Supreme Court bringing about societal transformation by utilizing the provisions of the Constitution. It is a structured method of bringing about change within the framework of constitutionalism, while adhering to the basic structure of the Constitution and the basic values defined in the system of government.

5. Living Will and Passive Euthanasia

The Supreme Court first legalized the concept of Living Will and Passive Euthanasia through the case of Common Cause v. Union of India. While Aruna Ramchandra Shanbaug legalized passive euthanasia, the Common Cause case further evolved and legalized the concept of Living Will and Passive Euthanasia as a comprehensive framework.

6. Criminal Law (Amendment) Act, 2013

The committee that led to the passing of the Criminal Law (Amendment) Act, 2013, was headed by Justice J.S. Verma. This Act brought massive amendments to criminal law, affecting provisions of the CrPC, IPC, and the JJ Act. Key changes included stricter punishments, the inclusion of new types of offenses, and provisions for trying individuals aged 16-18 as adults in certain circumstances, following a significant case in 2012.

7. Introduction of PIL in India

The Chief Justice of India (CJI) when the concept of Public Interest Litigation (PIL) was introduced in the Indian judicial system was Justice P.N. Bhagwati. Justice P.N. Bhagwati is also known as the "Father of PIL in India." The first PIL case was Hussainara Khatoon v. Home Secretary, State of Bihar, which discussed whether speedy trial is part of Article 21 and the principle of "Justice delayed is justice denied."

8. Preamble Not Part of the Constitution

The Supreme Court of India held that the Preamble is NOT a part of the Constitution of India in the In Re: Berubari Union case. (Memory Tip: Remember this point was explicitly contrasted with the Kesavananda Bharati case, which later established the Preamble as part of the Constitution.)

9. M.C. Mehta v. Union of India (1986) - Shriram Foods & Fertilizers Case

The M.C. Mehta v. Union of India (1986) case, also known as the Shriram Foods & Fertilizers Case, is related to the Oleum Gas Leak Case. (Memory Tip: The name "Shriram Foods & Fertilizers Case" itself provides a strong hint regarding the nature of the case.)

14. Right to Pollution-Free Water & Air

The PIL case that expanded Article 21 of the Indian Constitution to include the Right to Enjoyment of Pollution-Free Water and Air was Subhash Kumar v. State of Bihar. Other cases like Olga Tellis v. Bombay Municipal Corporation discussed the Right to Life including the Right to Livelihood, but were not related to environmental law.

15. Principle of Absolute Liability
