The One Hundred and Fourth Amendment of the Constitution of India, extends the deadline for the cessation of the reservation of seats for members from Scheduled Castes and Scheduled Tribes in the Lok Sabha and State Legislative Assemblies by a period of 10 years.

The reservation of seats for the Scheduled Castes and Scheduled Tribes was set to expire on 26 January 2020 as mandated by the Ninety Fifth Amendment^[1] but was extended for another 10 years with the given reason:

Although the Scheduled Castes and the Scheduled Tribes have made considerable progress in the last 70 years, the reasons which weighed with the Constituent Assembly in making provisions with regard to the aforesaid reservation of seats have not yet ceased to exist. Therefore, with a view to retaining the inclusive character as envisioned by the founding fathers of the Constitution, it is proposed to continue the reservation of seats for the Scheduled Castes and the Scheduled Tribes for another ten years i.e. up to 25th January, 2030 -Ravi Shankar Prasad, Minister of Law and Justice^[2]

The amendment does not, however, extend the period of reservation of the 2 Lok Sabha seats and seats in State Legislative Assemblies reserved for members of the Anglo-Indian Community and thus the practice of nominating two members of the Anglo-Indian community by the President of India under the recommendation of the Prime Minister of India was effectively abolished.

BE it enacted by Parliament in the Seventieth Year of the Republic of India as follows:—

1. (1) This Act may be called the Constitution (One Hundred and Fourth Amendment) Act, 2019.^[3]

(2) It shall come into force on the 25th day of January, 2020.

2. In article 334 of the Constitution,—

(a) for the marginal heading, the following marginal heading shall be substituted, namely:—

“Reservation of seats and special representation to cease after certain period”;

(b) in the long line, after clauses (a) and (b), for the words "seventy years", the words "eighty years in respect of clause (a) and seventy years in respect of clause (b)" shall be substituted.

The full text of Article 334 of the Constitution, after the 95th Amendment, is given below:

368. Reservation of seats and special representation to cease after ten years. Reservation of seats and special representation to cease after certain period.
