Political executives are government officials who participate in the determination and direction of government policy. They include heads of state and government leaders—presidents, prime ministers, premiers, chancellors, and other chief executives—and many secondary figures, such as cabinet members and ministers, councillors, and agency heads. By this definition, there are several thousand political executives in the U.S. national government, including the president, dozens of political appointees in the cabinet departments, in the agencies, in the commissions, and in the White House staff, and hundreds of senior civil servants. The same is true of most advanced political systems, for the making and implementation of government policy require very large executive and administrative establishments.

The crucial element in the organization of a national executive is the role assigned to the chief executive. In presidential systems, such as in the United States, the president is both the political head of the government and also the ceremonial head of state. In parliamentary systems, such as in Great Britain, the prime minister is the national political leader, but another figure, a monarch or elected president, serves as the head of state. In mixed presidential-parliamentary systems, such as that established in France under the constitution of 1958, the president serves as head of state but also wields important political powers, including the appointment of a prime minister and cabinet to serve as the government.

The manner in which chief executives are elected or selected is often decisive in shaping their role in the political system. Thus, although they receive their seals of office from the monarch, the effective election of British prime ministers usually occurs in a private conclave of the leading members of their party in Parliament. Elected to Parliament from only one of several hundred constituencies, they are tied to the fortunes of the legislative majority that they lead. By contrast, U.S. presidents are elected by a nationwide electorate, and, although they lead their party’s ticket, their fortunes are independent of their party. Even when the opposition party controls the Congress, their fixed term and independent base of power allow them considerable freedom of maneuver. These contrasts explain many of the differences in the roles of the two chief executives. British prime ministers invariably have served for many years in Parliament and have developed skills in debate and in political negotiation. Their major political tasks are the designation of the other members of the cabinet, the direction of parliamentary strategy, and the retention of the loyalty of a substantial majority of their legislative party. Presidential chief executives, on the other hand, often lack prior legislative and even national-governmental experience, and their main concern is with the cultivation of a majority in the electorate through the leadership of public opinion. Of course, since presidents must have a legislative program and often cannot depend on the support of a congressional majority, they may also need the skills of a legislative strategist and negotiator.

Another important area of contrast between different national executives concerns their role in executing and administering the law. In the U.S. presidential system the personnel of the executive branch are constitutionally separated from the personnel of Congress: no executive officeholder may seek election to either house of Congress, and no member of Congress may hold executive office. In parliamentary systems the political management of government ministries is placed in the hands of the party leadership in parliament. In the U.S. system, presidents often appoint to cabinet positions persons who have had little prior experience in politics, and they may even appoint members of the opposition party. In the British system, cabinet appointments are made to consolidate the prime minister’s personal ascendancy within the parliamentary party or to placate its different factions. These differences extend even further into the character of the two systems of administration and the role played by civil servants. In the U.S. system a change in administration is accompanied by the exodus of a very large number of top government executives—the political appointees who play the vital part in shaping day-to-day policy in all the departments and agencies of the national government. In Britain, when political control of the House of Commons changes, only the ministers, their parliamentary secretaries, and one or two other top political aids are replaced. For all practical purposes, the ministries remain intact and continue under the supervision of permanent civil servants.

In nearly all political systems, even in constitutional democracies where executive responsibility is enforced through free elections, the 20th century saw a remarkable increase in the powers of chief executives. The office of the presidency in the United States, like the office of prime minister in Britain, greatly enlarged the scope of its authority. One of the challenges of representative government is to develop more constitutional restraints on the abuse of executive powers while retaining their advantages for effective rule.

The judiciary

Like legislators and executives, judges are major participants in the policy-making process; and courts, like legislatures and administrative agencies, promulgate rules of behaviour having the nature of law. The process of judicial decision making, or adjudication, is distinctive, however, for it is concerned with specific cases in which an individual has come into conflict with society by violating its norms or in which individuals have come into conflict with one another, and it employs formal procedures that contrast with those of parliamentary or administrative bodies.

Established court systems are found in all advanced political systems. Usually there are two judicial hierarchies, one dealing with civil and the other with criminal cases, each with a large number of local courts, a lesser number at the level of the province or the region, and one or more courts at the national level. This is the pattern of judicial organization in Britain, for example. In some countries—for example, in France—although there is a double hierarchy, the distinction is not between courts dealing with criminal cases and other courts dealing with civil cases but rather between those that handle all civil and criminal cases and those that deal with administrative cases or challenges to the administrative authority of the state. Reflecting the federal organization of its government, the United States has two court systems: one set of national courts and 50 sets of state courts. By contrast, Germany, which is federal in governmental organization, possesses only a single integrated court system.

Local courts are found in all systems and are usually of two types. The first type deals with petty offenses and may include a traffic court, a municipal court, a small-claims court, and a court presided over by a justice of the peace or a local magistrate. The second type, sometimes called trial courts, are courts of first instance in which most cases of major importance are begun. These are the state superior courts in the United States, the county courts and quarter sessions in Britain, the tribunal de grande instance in France, and the district courts, or Landgerichte, in Germany. In some systems there is a level above the local court, usually referred to as assize courts, in which exceptionally serious crimes, such as homicide, are tried. Courts of appeal review the procedures and the law in the lower court and, in some instances, return the case for a new trial. In all systems there are national supreme courts that hear appeals and exercise original jurisdiction in cases of the greatest importance, such as those involving conflict between a state and a national government. Outside the regular court systems, there are sometimes found specialized judicial tribunals, such as administrative courts, or courts of claims that deal with special categories of cases.
