How does the legal system govern business activities?

"Our legal system affects everyone who lives and does business in the United States. The smooth functioning of society depends on the law, which protects the rights of people and businesses. The purpose of law is to keep the system stable while allowing orderly change. The law defines which actions are allowed or banned and regulates some practices. It also helps settle disputes. The legal system both shapes and is shaped by political, economic, and social systems. In any society, laws are the rules of conduct created and enforced by a controlling authority, usually the government. They develop over time in response to the changing needs of people, property, and business. The legal system of the United States is thus the result of a long and continuing process. In each generation, new social problems occur, and new laws are created to solve them. For instance, in the late 1800s corporations in certain industries, such as steel and oil, merged and became dominant. The Sherman Antitrust Act was passed in 1890 to control these powerful firms. Eighty years later, in 1970, Congress passed the National Environmental Policy Act. This law dealt with pollution problems, which no one had thought about in 1890. Today new areas of law are developing to deal with the internet and the recent financial scandals.\n\nCommon law is the body of unwritten law that has evolved out of judicial (court) decisions rather than being enacted by legislatures. It is also called case law. It developed in England and came to America with the colonists. All states except Louisiana, which follows the Napoleonic Code inherited from French settlers, follow the English system. Common law is based on community customs that were recognized and enforced by the courts. Statutory law is written law enacted by legislatures at all levels, from city and state governments to the federal government. Examples of statutory law are the federal and state constitutions, bills passed by Congress, and ordinances, which are laws enacted by local governments. Statutory law is the chief source of new laws in the United States. Among the business activities governed by statutory law are securities regulation, incorporation, sales, bankruptcy, and antitrust. Related to statutory law is administrative law, or the rules, regulations, and orders passed by boards, commissions, and agencies of federal, state, and local governments. The scope and influence of administrative law have expanded as the number of these government bodies has grown. Federal agencies issue more rulings and settle more disputes than all the courts and legislatures combined. Some federal agencies that issue rules are the Civil Aeronautics Board, the Internal Revenue Service, the Securities and Exchange Commission, the Federal Trade Commission, and the National Labor Relations Board.\n\nBusiness law is the body of law that governs commercial dealings. These laws provide a protective environment within which businesses can operate. They serve as guidelines for business decisions. Every businessperson should be familiar with the laws governing his or her field. Some laws, such as the Internal Revenue Code, apply to all businesses. Other types of business laws may apply to a specific industry, such as Federal Communications Commission laws that regulate radio and TV stations. In 1952 the United States grouped many business laws into a model that could be used by all the states. The Uniform Commercial Code (UCC) sets forth the rules that apply to commercial transactions between businesses and between individuals and businesses. It has been adopted by 49 states; Louisiana uses only part of it. By standardizing laws, the UCC simplifies the process of doing business across state lines. It covers the sale of goods, bank deposits and collections, letters of credit, documents of title, and investment securities."
