Prior to 1990, the city also had a powerful Board of Estimate, a unique legislative-executive hybrid. Although it could not pass laws, it shared authority for the city budget with the council and controlled functions such as land use, municipal contracts, franchises, and water and sewer rates. The Board's membership consisted of the mayor, comptroller, president of the City Council, and the five borough presidents. The three citywide officials each cast two votes, and the borough presidents one each. In 1989, the Supreme Court of the United States struck down the Board of Estimate as violating the principle of "one man, one vote", due to the dramatically unequal numbers of constituents being represented by each borough president. The city subsequently adopted its current arrangement by referendum.
