How did the constitution change reservation policies for a particular community in 1980 and how long did these changes last?
In 1980, the Constitution (Forty-fifth Amendment) Act changed reservation policies for a particular community by substituting the words "forty years" for "thirty years." This change took effect on 25th January 1980. The new policy allowed for a gradual decrease in reservations during each two-year period, with the goal of eliminating all such reservations ten years after the commencement of the Constitution.
