what is the difference between common law statutory law and constitutional law
Constitutional law Not all nation states have codified constitutions, though all such states have a jus commune, or law of the land, that may consist of a variety of imperative and consensual rules. These may include customary law, conventions, statutory law, judge-made law, or international rules and norms. Constitutional law deals with the fundamental principles by which the government exercises its authority. In some instances, these principles grant specific powers to the government, such as the power to tax and spend for the welfare of the population. Other times, constitutional principles act to place limits on what the government can do, such as prohibiting the arrest of an individual without sufficient cause.
Law of the land This term was used in 1787 to write the Supremacy Clause of the U.S. Constitution, which states: "This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the authority of the United States, shall be the supreme Law of the land...."[18] The Supremacy Clause is the only place in the Constitution where this exact term was used.
Statute of limitations In civil law systems, similar provisions are typically part of their civil or criminal codes and known collectively as periods of prescription. The cause of action dictates the statute of limitations, which can be reduced (or extended) to ensure a fair trial.[2] The intention of these laws is to facilitate resolution within a "reasonable" length of time.[3] What period of time is considered "reasonable" varies from country to country, and within countries such as the United States from state to state.[4][5] Within countries and states, the statute of limitations may vary from one civil or criminal action to another. Some nations have no statute of limitations whatsoever.
