Leask v Commonwealth (1996) 187 CLR 579 is a High Court of Australia case that discussed the role of proportionality in the Australian Constitution.
The act under question was the Financial Transactions Reports Act 1988 (Cth), which imposed an obligation on 'cash dealers' to report all transactions above $10,000 to a statutory authority. It was also an offence if it could be proved the transactions were designed to avoid tracking. The offence was a strict liability offence.
Once there is a sufficient connection between the Act and the head of power, proportionality is irrelevant for non-purposive powers. Whether or not there is a sufficient connection does not rely on the desirability of the legislation.
It was noted that the law was disproportionate to the currency and coins power (section 51(xii)), and that it was an inappropriate means to achieving the end. (Proportionality may be examined by testing if the law is appropriate and adapted to some means.) Dawson J noted that the test of whether the measures in a law are appropriate and necessary to achieve certain objectives, while used in Europe, was irrelevant for the Australian Constitution; "[t]hey are essentially political rather than judicial considerations".
Re Dingjan; Ex parte Wagner described the process by which it is determined whether a law is "with respect to" a section 51 head of power:
Thus, the connection involves some kind of degree, but once it has been established, it does not matter whether the law is appropriate for its aims.
However, proportionality may be relevant, and a law not invalid, if an immunity conferred by a limitation of a power is affected incidentally by the achievement of a legitimate end.
Sovereign immunity, or crown immunity, is a legal doctrine whereby a sovereign or state cannot commit a legal wrong and is immune from civil suit or criminal prosecution, strictly speaking in modern texts in its own courts. A similar, stronger rule as regards foreign courts is named state immunity.
Landmark court decisions, in present-day common law legal systems, establish precedents that determine a significant new legal principle or concept, or otherwise substantially affect the interpretation of existing law. "Leading case" is commonly used in the United Kingdom and other Commonwealth jurisdictions instead of "landmark case" as used in the United States.
Pith and substance is a legal doctrine in Canadian constitutional interpretation used to determine under which head of power a given piece of legislation falls. The doctrine is primarily used when a law is challenged on the basis that one level of government has encroached upon the exclusive jurisdiction of another level of government.
Section 51 of the Constitution of Australia grants legislative powers to the Australian (Commonwealth) Parliament only when subject to the Constitution. When the six Australian colonies joined together in Federation in 1901, they became the original States and ceded some of their powers to the new Commonwealth Parliament. There are 39 subsections to section 51, each of which describes a "head of power" under which the Parliament has the power to make laws.
Australian constitutional law is the area of the law of Australia relating to the interpretation and application of the Constitution of Australia. Several major doctrines of Australian constitutional law have developed.
The Government of Australia is the government of the Commonwealth of Australia, a federal parliamentary constitutional monarchy. It is also commonly referred to as the Australian Government, the Commonwealth Government, or the Federal Government.
Polyukhovich v The Commonwealth [1991] HCA 32; (1991) 172 CLR 501, commonly referred to as the War Crimes Act Case, was a significant case decided in the High Court of Australia regarding the scope of the external affairs power in section 51(xxix) of the Constitution and the judicial power of the Commonwealth.
Section 51(xxix) of the Australian Constitution is a subsection of Section 51 of the Australian Constitution that gives the Commonwealth Parliament of Australia the right to legislate with respect to "external affairs".
Section 51(xxxvii) of the Constitution of Australia is a provision in the Australian Constitution which empowers the Australian Parliament to legislate on matters referred to it by any state. As Australia is a federation, both states and the Commonwealth have legislative power, and the Australian Constitution limits Commonwealth power. Section 51(xxxvii) allows for a degree of flexibility in the allocation of legislative powers.
Section 51(vi) of the Australian Constitution, commonly called the defence power, is a subsection of Section 51 of the Australian Constitution that gives the Commonwealth Parliament the right to legislate with respect to the defence of Australia and the control of the defence forces. The High Court has adopted a different approach to the interpretation of the defence power, which emphasises the purpose of the legislation, primarily the defence of Australia, rather than the subject matter.
Section 91(27) of the Constitution Act, 1867, also known as the criminal law power, grants the Parliament of Canada the authority to legislate on:
27. The Criminal Law, except the Constitution of Courts of Criminal Jurisdiction, but including the Procedure in Criminal Matters.
Proportionality is a general principle in criminal law used to convey the idea that the severity of the punishment of an offender should fit the seriousness of the crime. The concept of proportionality is used as a criterion of fairness and justice in statutory interpretation processes, especially in constitutional law, as a logical method to assist in discerning the correct balance between the sanction or punishment imposed and the severity of the prohibited act. Under international humanitarian law governing the legal use of force in an armed conflict, proportionality and distinction are important factors in assessing military necessity.
Strickland v Rocla Concrete Pipes Ltd, also known as the Concrete Pipes Case, is a High Court of Australia case that discusses the scope of the corporations power in section 51(xx) of the Australian Constitution. This was an important case in Australian constitutional law because it overruled the decision in the earlier case of Huddart, Parker & Co Pty Ltd v Moorehead, which held that the corporations power only extended as far as the regulation of their conduct in relation to their transactions with or affecting the public. Since this case, the Commonwealth has had at least the ability to regulate the trading activities of trading corporations, thus opening the way for an expansion in Commonwealth power.
South Australia v Commonwealth is a decision of the High Court of Australia that established the Commonwealth government's ability to impose a scheme of uniform income tax across the country and displace the State. It was a major contributor to Australia's vertical fiscal imbalance in the spending requirements and taxing abilities of the various levels of government, and was thus a watershed moment in the development of federalism in Australia.
Nationwide News Pty Ltd v Wills is a High Court of Australia case that deals with a number of issues regarding the Australian Constitution, including the Express right free interstate trade and commerce, the implied freedom of political communication, and the role of proportionality.
The Crimes Act 1914 (Cth) is one of the first recognisable compilations of federal criminal law since federation in 1901. The Crimes Act deals with the most serious criminal offences against the Commonwealth. Amongst other things, Volume 2 of the Crimes Act deals with offences against the administration of justice in federal proceedings, piracy, offences relating to postal services, and etc.
The Constitution of Australia, or Australian Constitution, is the supreme law under which the government of the Commonwealth of Australia operates, including its relationship to the States of Australia. It consists of several documents. The most important is the Constitution of the Commonwealth of Australia, which is referred to as the "Constitution" in the remainder of this article. The Constitution was approved in a series of referendums held over 1898–1900 by the people of the Australian colonies, and the approved draft was enacted as a section of the Commonwealth of Australia Constitution Act 1900 (Imp), an Act of the Parliament of the United Kingdom.
Pape v Commissioner of Taxation is an Australian court case concerning the constitutional validity of the Tax Bonus for Working Australians Act 2009 (Cth) which seeks to give one-off payments of up to $900 to Australian taxpayers. The decision of the High Court of Australia was announced on 3 April 2009, with reasons to follow later.
Farey v Burvett, is an early High Court of Australia case concerning the extent of the defence power of the Commonwealth. The majority of the Court took an expansive view of the defence power in a time of war, holding that the defence power extended to fixing the maximum price for bread. The Court adopted a different approach to the interpretation of the defence power which emphasised the purpose of the legislation, the defence of Australia, rather than the subject matter. As the law fell within a Commonwealth power, whether the law was necessary or appropriate for the defence of Australia was a matter for Parliament.
