Because of the federal nature of our Constitution and because of its provisions the Senate undoubtedly has constitutional power to refuse or defer supply to the Government. Because of the principles of responsible government a Prime Minister who cannot obtain supply, including money for carrying on the ordinary services of government, must either advise a general election or resign. If he refuses to do this I have the authority and indeed the duty under the Constitution to withdraw his Commission as Prime Minister. The position in Australia is quite different from a position in the United Kingdom. Here the confidence of both Houses on supply is necessary to ensure its provision. In the United Kingdom the confidence of the House of Commons alone is necessary. But both here and in the United Kingdom the duty of the Prime Minister is the same in a most important aspect – if he cannot get supply he must resign or advise an election. (en)
