This amendment was aimed at addressing the issue of social and economic inequality and ensuring equal opportunities for all citizens.

Key Objective:

The main objective of the constitutional amendment made in 1992 was to introduce reservation for economically weaker sections (EWS) in India.

Explanation:

The 1992 constitutional amendment introduced Article 15(6) and Article 16(6) to provide reservation for economically weaker sections in educational institutions and government jobs, respectively. These provisions allowed the government to reserve a certain percentage of seats and posts for individuals from economically weaker sections, regardless of their caste or religion.

Reservation Criteria:

The reservation criteria for economically weaker sections were defined based on income and asset ownership. Individuals with an annual family income below a certain threshold and those who owned less than a specified limit of assets were eligible for reservation under this category.

Implementation:

The constitutional amendment empowered the central and state governments to implement the reservation for economically weaker sections. The governments were responsible for defining the specific criteria for eligibility, the percentage of reservation, and the process for implementation.

Impact:

The amendment had a significant impact on the Indian society by expanding the scope of reservation beyond caste-based categories. It aimed to provide opportunities for individuals who were economically disadvantaged, irrespective of their caste, to access education and secure government jobs.

Conclusion:

The constitutional amendment made in 1992 in India aimed to provide reservation for economically weaker sections in educational institutions and government jobs. This amendment was a step towards ensuring equal opportunities for all citizens and addressing social and economic inequality. By extending reservation benefits to economically disadvantaged individuals, the amendment aimed to promote inclusivity and uplift the marginalized sections of society.
