There are different sources of law, depending on how the law is established. Constitutional law is a set of fundamental principles. Legal law is determined by the legislator. The common law is determined by the judicial system within the judiciary. The right to regulate is also controlled by the judiciary. Each country`s legal system has its own sources of law, but for systems that enact constitutions, constitutions are the most fundamental sources of law.  A constitution is a charter that establishes the government and the rules by which the government must function. The U.S. Congress enacts federal laws and those laws apply in all 50 states. An example of federal legislation is the Clean Air Act, a federal law that regulates air emissions from stationary and mobile pollution sources.
This law is a federal law and applies as such to all stationary and mobile sources of air pollution in all states of the country. Common law systems, such as ours, are largely adversarial in which two parties investigate the truth and argue their case before an impartial person or group of people, usually a jury or judge, who are trying to determine whether or not they agree with what each party has presented as evidence in the case.  sourcesofamericanlaw.lawbooks.cali.org/chapter/administrative-regulations/ The four main sources of law are constitutional law, law or law, regulatory law and customary law. The four main sources of law are established and maintained by the three branches of government: legislative, judicial and executive. There are four main sources of law in the U.S. legal system, and they are constitutions, laws, regulations, and jurisprudence. Responsibility for the main sources of law is divided between the three branches of government, namely the judiciary, the legislative and the executive.

Once you have a thorough understanding of this lesson, measure your ability to analyze the sources of law in the American legal system, which include the Constitution, statutes, regulations, and common law systems. The judiciary can be observed respecting the four main sources of law and overseeing law-related processes from the local and state levels to the Supreme Court.
Our ultimate source of law is really what connects all other sources. Since there are several sources of law, they sometimes conflict with each other. There is also the problem of ensuring that each law is applied consistently over time. A common law system is used here. A common law system is a legal system based on historical cases and precedents. In other words, this type of system looks at past cases that are similar to a current case and tries to govern in the same way. In our example of the Liquor Act earlier, if you were breaking that law, a judge who was trying to punish you would look at previous cases to see how the courts treat underage drinkers and then try to make as accurate a decision as possible. Over the course of two centuries, the legal system of the United States has become a model for other nations of the world that are trying to make various laws. In this presentation, we discussed the four sources of law that interact, overlap, and work together to create a robust set of legal guidelines. Everywhere you look, there are people or systems that prevent us from harming ourselves or others that serve as remedies if we are hurt. Your mother or father could have been the source of justice in every way if you had behaved badly. When you play a sport, you know that the game is subject to certain rules and that officials are on hand to make sure they are respected.
The same goes for almost every action we take in our daily lives. These rules and regulations come from a number of places, and some take precedence over others. In this lesson, we will briefly discuss the sources of law in the American legal system, including the Constitution, statutes, regulations, and common law.  University of Idaho School of Law, “Sources of Law,” www.uidaho.edu/~/media/UIdaho-Responsive/Files/law/library/legal-research/guides/sources-law.ashx. In this presentation, we will examine the four main sources of law at the state and federal levels. These four sources of law are the U.S. Constitution, federal and state laws, bylaws, and case law. Check. There are a number of rules that govern our behavior in the United States. The authority for these rules comes from several places. The main source of law we have is the U.S. Constitution, followed by federal, state, and local laws, and then the regulatory authority of federal agencies.
Finally, our customary law system links all other sources of law and prevents them from coming into conflict with each other and ensures consistency in the application of the law. There are four main types of laws: constitution, laws, regulations and general laws. Responsibility for these four main types of legislation is divided among the three branches of the United States government, which are executive, legislative, and judicial. The U.S. legal system and the founding principles of the U.S. government are outlined in the U.S. Constitution and upheld by U.S. citizens and its branches of government.
The order in which we take each source of law depends on the weight that our legal system attaches to each source. Therefore, our first source of law, the Constitution, is the most important source of law available to us. In fact, the constitution contains a primacy clause that establishes itself as the supreme law of the land. The Constitution defines the structure and power to which our various branches of government are entitled. It also has a list of amendments, including the first ten, known as the Bill of Rights, that outline the protections and rights reserved for U.S. citizens. The next source of constitutional law is legislation. Laws are written laws passed by the legislature of our government.
The words “law” and “statutes” for our purposes here are quite synonymous.
