Under the 1961 Constitution, the Legislative Assembly had 65 elected members: 50 constituency members and 15 district members. The voter rolls had education, property and income qualifications. The main A roll was for citizens who satisfied high standards in these regards and 95% of its members were white and 5% were black or Asian. The B roll had lower qualification standards and 90% of its members were black and 10% were white or Asian. The B roll was about one-tenth of the size of the A roll. Both rolls voted in elections for constituencies and districts, but for elections in the constituencies, the B roll vote was capped at 20% of the total, and for elections in the districts, the A roll vote was capped at 20% of the total. This procedure was known as 'cross-voting'. In practice, the 50 constituency members would all be white and the 15 district members would mostly be black.
