On the Constitution of New Zealand
An Introduction to the Foundations of the Current Form of Government
By Rt Hon Sir Kenneth Keith, ONZ
A constitution: What is it?
A constitution is about public power, the power of the state. It describes and establishes the major institutions of government, states their principal powers, and regulates the exercise of those powers in a broad way. While all constitutions have these general characteristics, each constitution is affected by the national character of the state it services.
The New Zealand constitution: Its main features
The New Zealand constitution is to be found in formal legal documents, in decisions of the courts, and in practices (some of which are described as conventions). It reflects and establishes that New Zealand is a monarchy, that it has a parliamentary system of government, and that it is a democracy. It increasingly reflects the fact that the Treaty of Waitangi is regarded as a founding document of government in New Zealand. The constitution must also be seen in its international context, because New Zealand governmental institutions must increasingly have regard to international obligations and standards.
The Constitution Act 1986
The Constitution Act 1986 is the principal formal statement. The Act first recognises that the Queen-the Sovereign in right of New Zealand-is the Head of State of New Zealand, and that the Governor-General appointed by her is her representative in New Zealand. Each can, in general, exercise all the powers of the other.
The Act then deals with the Executive, the legislature, and the judiciary.
The provisions about the Executive emphasise its parliamentary character. Only Members of Parliament may be Ministers of the Crown and Parliamentary Under-Secretaries. One Minister may also act for another.
Parliament-the legislature-consists of the Sovereign and the House of Representatives. The members of the House are elected in accordance with the Electoral Act 1993. Each Parliament has a term of three years, unless it is earlier dissolved. The Governor-General has the power to summon, prorogue and dissolve Parliament. After each general election, Parliament is to meet within six weeks of the date fixed for the return of the writs.
The Constitution Act provides for Parliament to have full power to make laws; a Bill passed by the House becomes law when the Sovereign or Governor-General assents to it.
The Constitution Act reaffirms the constitutional principles about parliamentary control of public finance: the Crown may not levy taxes, raise loans, or spend public money except by or under an Act of Parliament.
The provisions about the judiciary also relate back to long established constitutional principle. To enhance their independence, the Judges of the Supreme Court, the Court of Appeal and the High Court are protected against removal from office and reduction of salary.
Other sources of the constitution
The other major sources of the constitution include:
- The prerogative powers of the Queen under which, for instance, the Queen issued the Letters Patent Constituting the Office of the Governor-General of New Zealand in 1983 and conferred her powers in respect of New Zealand on the Governor-General. The Queen appoints the Governor-General who, in general, exercises her prerogative powers. The Queen or Governor-General appoints and dismisses members of the Executive Council and Ministers of the Crown. Those powers are part of the common law. They exist independently of statutes, although statutes can, of course, limit or even supersede them.
- Other relevant New Zealand statutes, such as the State Sector Act 1988, the Electoral Act 1993, and the Judicature Act 1908, relating in turn to the three branches of government, as well as the Ombudsmen Act 1976, the Official Information Act 1982, the Public Finance Act 1989 and the New Zealand Bill of Rights Act 1990.
- Relevant English and United Kingdom statutes, such as Magna Carta 1297, the Bill of Rights 1688, the Act of Settlement 1700 (regulating succession to the throne among other matters) and the Habeas Corpus Acts, all confirmed as part of the law of New Zealand by the Imperial Laws Application Act 1988. These statutes also regulate the relations between the state and the individual.
- Relevant decisions of the courts, for instance, upholding rights of the individual against the powers of the state, and determining the extent of those powers.
- The Treaty of Waitangi, which may indicate limits in our polity on majority decision making. The law may sometimes accord a special recognition to Māori rights and interests such as those covered by Article 2 of the Treaty. And in many other cases the law and its processes should be determined by the general recognition in Article 3 of the Treaty that Māori belong, as citizens, to the whole community. In some situations, autonomous Māori institutions have a role within the wider constitutional and political system. In other circumstances, the model provided by the Treaty of Waitangi of two parties negotiating and agreeing with one another is appropriate. Policy and procedure in this area continues to evolve.
- The conventions of the constitution, which in practice regulate, control and in some cases transform the use of the legal powers arising from the prerogative or conferred by statute. The most important conventions arise from the democratic character of our constitution.
Constitutional conventions are of critical importance to the working of the constitution, even though they are not enforceable by the courts. In 1982, the Supreme Court of Canada summarised the constitutional position in that country in an equation: constitutional conventions plus constitutional law equal the total constitution of the country.
The underlying principle: Democracy
The Queen reigns . . .
That basic equation and the democratic character of the main conventions appear clearly in relation to the powers of the Queen and Governor-General under the law. Thus they may appoint Ministers and other holders of important offices (such as the Judges, the Defence Chiefs, the Ombudsmen, and the Controller and Auditor-General), they may dismiss them (following certain procedures), they may summon and dissolve Parliaments, they may assent - or not - to Bills passed through the House, and they may agree - or not - to proposed regulations and Orders submitted to them by the Executive Council and Ministers.
. . . but the government rules . . .
The Queen and the Governor-General are free to take those steps as a matter of law. But, as a matter of convention, they do so only on the advice of the Prime Minister or Ministers who have the support of the House of Representatives - that is, on the advice of those who are elected by the New Zealand voters, and who belong to a party which has a majority in the House; or who are part of a coalition which has a majority; or who, as a minority, are accepted by the House as able to sit on the Treasury benches. There must always be a ministry (the government of the day) to advise the Queen or Governor-General.
. . . so long as it has the support of the House of Representatives
That convention of course incorporates its own limit - one that conforms with democratic principle. If the government loses the support of the House, or if the Prime Minister loses his or her support as the leader of that government, then the ministry or the Prime Minister is likely to change: another party or combination of parties may now have the support of the House, or a new leader may be identified as Prime Minister. Or the Governor-General may face a more difficult situation because the position within the House or the governing party is unclear.
Situations like this were rare in New Zealand under the first past the post electoral system, but have been less rare since the introduction of the proportional representation electoral system. The essential principle in such situations continues to be that the Queen, as a constitutional monarch, or the Governor-General, as her representative, acts in accordance with the advice of the Prime Minister or Ministers who have the necessary support of the House of Representatives. Where that support is unclear, the Governor-General relies on the elected representatives in the House, and especially the party leaders, to clarify whether a party or grouping of parties has the support of the House to govern, or whether fresh elections will be required. In the meantime, the incumbent government continues in office, where necessary acting in accordance with the convention on caretaker government.
This is not to deny the important role of the Governor-General in the business of government. Practice and the Letters Patent indicate that the role includes being informed and consulted, and advising and warning Ministers. The office has central symbolic, unifying, and representative roles, as well as the important legal powers already mentioned.
In a broad sense, it is the ministry or government of the day which governs. The members of the ministry as a whole have the support of the House and must take collective and individual responsibility for their decisions, the decisions that are taken in their name, and the measures they propose. That is the position in law and in convention. That responsibility and power to take decisions results from the electoral process and the political contest.
Real power and legal form
The decisions often take a legal form that departs from that practical and conventional reality; the decision taken in fact by Cabinet has then to be taken, as a matter of law, by the Governor-General in Council, the Governor-General or a Minister, as the particular statute requires; or the Bill passed by the House through all its readings has to be assented to by the Governor-General to become law. The Cabinet, essentially a body established by convention, has no legal power; and the House acting alone has very limited powers to take decisions with full legal effect.
The role of political parties
Political parties provide a vital link between the people, Parliament and the government. The competition for the power of the state, exercised through the House of Representatives and the ministry, is a competition organised by and through political parties. It is party strength in the House after elections that decides who is to govern. It is the parliamentary party or parties with the support of the House (and the ability to ensure supply - the money to fund the state's functions) that provides the government.
The importance of political parties in our constitutional system is recognised in the Electoral Act 1993 and in Standing Orders. It follows that parties' internal procedures, for instance in respect of the means of selecting their leaders and members of Cabinet, have an important practical effect on our governmental arrangements. The relationships between parties, including any agreements that they may reach, have become more important under coalition and minority governments.
The role of the Prime Minister and Ministers
The Prime Minister is the head of government, chairs Cabinet and has a general coordinating responsibility across all areas of government. By constitutional convention, the Prime Minister alone can advise the Governor-General to dissolve Parliament and call an election, and to appoint, dismiss, or accept the resignation of Ministers.
Ministers constitute the ministry, or executive arm of government. Their powers rise from legislation and the common law (including the prerogative). Ministers are supported in their portfolios by the public service.
The role of the public service
The role of the public service is stated in some detail in legislation, particularly in the provisions of the State Sector Act 1988, the Public Finance Act 1989 and the Official Information Act 1982, as well as a great number of particular statutes. Constitutional principles and that legislation support four broad propositions (among others). Members of the public service:
- are to act in accordance with the law;
- are to be imbued with the spirit of service to the community;
- are (as appropriate) to give free and frank advice to Ministers and others in authority, and, when decisions have been taken, to give effect to those decisions in accordance with their responsibility to the Ministers or others;
- when legislation so provides, are to act independently in accordance with the terms of that legislation.
Public servants meet those obligations in accordance with important principles such as neutrality and independence, and as members of a career service.
Independent powers of decision: statutory bodies
Members of the public service sometimes have independent statutory powers of decision, over which Ministers do not have control and for the exercise of which they are not responsible. Other parts of the broad state sector are also distinct from Ministers and not subject to their control and responsibility in the same way that departments and their members usually are.
The bodies set up separately from government include regulatory agencies, providers of a wide range of services, state trading bodies, and supervisory, control, or advice agencies.
In establishing such bodies, over a very long period, Parliament has recognised and reaffirmed that much public power should not be concentrated. It should be allocated to distinct bodies with varying degrees of independence from the Executive. This separation and independence may help ensure, for instance, a judicial independence of decision, equitable distribution of funds, the pursuit of commercial profit and business efficiency, or effective and credible processes of independent scrutiny, supervision and advice.
Towards more open government
Over recent decades the processes of government have become more open. Notably, in 1982 the Official Information Act reversed the basic principle of the Official Secrets Act 1951: the principle now is that official information is to be made available to those seeking it unless there is good reason for withholding it. Those reasons relate to public interest such as the national security and law enforcement, and to private interests such as confidences and privacy. Underlying that principle are a number of purposes, including enabling the more effective participation of the people of New Zealand in the making and administration of laws and policies, and promoting the accountability of Ministers of the Crown and officials, with the consequence of enhancing respect for the law and promoting the good government of New Zealand.
The emphasis on greater transparency in decision making and policy development is also to be seen in the legislation governing the government's spending and fiscal policies (especially the Public Finance Act 1989), and in the operation of the parliamentary select committee processes.
Individuals, autonomy and majority rule
In a range of ways, including those just indicated, individuals and communities do participate directly in political and governmental processes important to them. There is for instance much emphasis in law and in practice on those exercising public power giving fair hearings to and consulting those affected by the exercise of that power. Also relevant is the enactment of the Citizens Initiated Referenda Act 1993.
A balance has to be struck between majority power and minority right, between the sovereignty of the people exercised through Parliament and the rule of the law, and between the right of elected governments to have their policies enacted into law and the protection of fundamental social and constitutional values. The answer cannot always lie with simple majority decision making. Indeed, those with the authority to make majority decisions often themselves recognise that their authority is limited by understandings of what is basic in our society, by convention, by the Treaty of Waitangi, by international obligations and by ideas of fairness and justice.
The international context
Major changes in science, technology, communications, trade patterns, financial systems, population movement, the environment and many other matters of international concern mean that more and more law is made through international processes. The powers of national governmental institutions are correspondingly reduced. This has important consequences for national and international constitutional processes. Under changes to parliamentary procedures, Parliament has a greater opportunity to scrutinise and comment on the more significant international treaties before they are ratified by the Executive.
Changing the constitution
In theory, many parts of the constitution can be amended by legislation passed by a simple majority of the Members of Parliament. That power is, however, restrained by law, convention, practice and public acceptance.
Some limits on constitutional change arise from the international obligations which have just been mentioned.
Certain key elements of the electoral system can be amended only if the people in a referendum approve, or three-quarters of the Members of Parliament agree. The provisions thus protected concern the three-year term of Parliament, the membership of the Representation Commission, the division of New Zealand into general electoral districts, the voting age, and the method of voting. In accordance with that requirement, the amendments made in the last 40 years to those provisions have been made only following agreement between the major political parties in the House or, in the notable instance of the change to proportional representation, following a binding referendum (which had itself been preceded by an indicative referendum).
It also appears to be accepted, at the level of convention, that those voting requirements also apply to any proposal to amend that protective provision. Similarly, Standing Orders provide that an entrenched provision should be introduced by the House only by the vote which would be required for the amendment or repeal of the provision being entrenched. The 1986 Constitution Act itself was enacted with general bipartisan support in the House. And recommendations to the House for new Standing Orders, in accordance with convention, are adopted by consensus in the Standing Orders Committee.
Other constitutional changes arise from legislation enacted in the regular way, such as the New Zealand Bill of Rights Act 1990, from decisions of the courts, from new prerogative instruments, and from changing practices (which may contribute to new conventions). Some matters are better left to evolving practice rather than being the subject of formal statement. But such development, like other changes to the constitution, should always be based on relevant principle.
