With the transformation of British monarchy into constitutional monarchy, the British monarchs began to act on the advice of the parliament and ministers.
Naturally the responsibility for actions of the King also came to be focused on the ministers and the dictum ‘The King can do no wrong gained currency. In short, we can say that along with the evolution of constitutional monarchy the financial and legislative powers of parliament also grew.
Another notable feature about the British Parliament is that initially the upper house of parliament (viz. House of Lords) enjoyed a predominant position, but gradually the popular house of Commons) asserted itself and gained ascendancy over the House of Lords. Following rejection of Lloyd George’s Budget of 1909, the powers of the House of Lords were severely restricted (after making it an electoral issue) under the Parliament Act of 1911.
As a result of this Act the House of Lords was deprived of the right to interfere with the Budget and the Speaker of the House of Commons was authorized to exclude any Bill from the jurisdiction of the House of Lords by certifying it as a Money Bill. Thereafter, the House of Lords could not block the passage of Money Bill and could merely delay its enactment for one month. The general legislative powers of the House of Lords were also curtailed. These powers were further curtailed under the Parliament Act of 1949.
