Question

the most extreme form of supermajority is found in most us courtrooms, as well as in the courts of australia and ireland. for a defendant to be found guilty in a jury trial, the jury must unanimously agree; otherwise, the defendant will either be released or face another trial. this is called a unanimity rule.
how might these differing voting rules be explained? one sensible rationale is that the greater the consequences of making an “incorrect” decision or the longer those consequences will last, the greater the need for a supermajority to guard against making rash or incorrect decisions. one of the most coercive things a state can do is to deprive a citizen of their liberty by imprisoning them, and one of the worst mistakes is to imprison an innocent person, so most democracies make it relatively difficult to convict suspected criminals. a unanimity rule helps guard against wrongful convictions, although it does not entirely prevent them.
constitutions are the core document establishing the basic structure of the state, and laws are meant to address current problems. a constitution typically outlines the government’s general powers and duties, while laws fill in the specifics regarding these matters. (for more on constitutions, see chapter 1: what is politics and what is political science?) to change a constitution generally requires a supermajority, while changing laws requires only a simple majority. think of it this way: constitutions are the foundations of the house, while laws are the paint in the rooms. it is hard to change the foundation because it is meant to be durable, but it is easier to repaint the bedroom because people’s taste in colors can change over the seasons. that is why voting rules typically make constitutional changes subject to supermajority votes and laws changeable by a simple majority. this is not true in every country, however. in an effort to ensure that legislation has support from minority parties, in south korea a 60 percent supermajority is required in the national assembly to bring any measure up for a vote.
voting rules have another, more self - interested, political rationale. those setting the rules have incentives to be durable because the constitution represents how they believe their country should be ordered for generations to come. therefore, they make the constitution difficult to change. there is also a self - interested reason for making constitutions difficult to change. those writing them may be currently in power, but they can imagine a time when they may be in the minority. constitutional authors thus try to lock in their preferences in ways that will make it

Explanation:

The text discusses constitutions, voting rules, and the rationale behind unanimity in jury - trials to safeguard individual liberties and prevent hasty or incorrect decisions by majorities. It touches on the difficulty of changing constitutions and the incentives for those writing them. The key concepts here are related to the structure and function of political systems and the protection of individual rights within them.

Answer:

The text explores the importance of constitutions in establishing the basic structure of a state, the power - distribution between the state and laws, and the role of voting rules and unanimity in protecting individual liberties. It also mentions how constitutions can be difficult to change and the self - interested motives of those writing them. The main idea is about the balance between majority rule and protecting individual rights in a political context.
