 When Rawls says that the political constitution is part of the basic structure, he does not just mean the procedures that specify how laws are enacted and that define offices and positions of political authority. He means more or less the entire legal system, including most public and private law, that is the product of the constitution in this procedural sense. Modern legal systems, such as the federal system of the United States, are made up of countless acts of legislation, administration, judicial precedent, and other legal rulings that are issued by multiple legal bodies with lawmaking authority. An economic system that is regulated by the legal norms that are issued by the political constitutions is also part of the basic structure. Here, of course, the legal norms of property, contract, commercial law, intangibles, and so on that are essential for economic production and exchange are to be included in the basic structure. What makes possible the incredibly complicated system of legal norms that underlie production, exchange, and consumption is a unified political system that specifies these norms and revises them to meet changing conditions….Nothing comparable to the basic structure of society exists on the global level.
