| Status: Amended | |
The Twelfth Amendment of the Constitution of India, officially known as The Constitution (Twelfth Amendment) Act, 1962, incorporated Goa, Daman and Diu as the eighth Union territory of India, by amending the First Schedule to the Constitution. India acquired control of Goa, Daman and Diu from Portugal in December 1961. The amendment also amended clause (1) of article 240 of the Constitution to include therein these territories in order to enable the President to "make regulations for the peace, progress and good government of the territory".
The 12th Amendment retroactively came into effect on 20 December 1961, the day following the formal ceremony of official Portuguese surrender, when Governor General Manuel António Vassalo e Silva signed the instrument of surrender bringing to an end 451 years of Portuguese rule in Goa. On 30 May 1987, the union territory was split, and Goa was made India's twenty-fifth state, with Daman and Diu remaining a union territory.
