The Parliament proposed at the Convention of 1891 was to adopt the nomenclature of the United States Congress. This proposal provided the broad outline of a Federal government. Its lower house was to be elected by districts drawn up on the basis of their population, while in the Senate there was to be equal representation for each "province". This American model was mixed with the Westminster system by which the Prime Minister and other ministers would be appointed by the representative of the British Crown from among the members of the political party holding a majority in the lower House.
