The American legal system is one of the most complex in the world. Practically all the more or less important laws that have ever been applied at the federal level (there are some exceptions, which were applied only at the state or city level) are included in the special Legislative Code of the United States – the second most important document after the Constitution. The country’s legislation is based on the Constitution (as in Russia). This document guarantees citizens equal rights and the opportunity to assert them.
America is also famous for its ridiculous legislative projects which have been in effect for several years or even centuries, though serious penalties for their violation are unlikely to ever follow.
The main legislative document is the Constitution of the United States. It is the basis upon which all existing laws of the country, individual states, and cities are drafted and edited. Each U.S. state and even a city is free to pass its own bills, but final passage requires congressional approval. That said, all proposed individual state and city bills cannot conflict with the Constitution, applicable laws at the federal level, basic human rights, and applicable laws of the state itself.
Basically, states and cities use this right to impose/revoke additional taxes, duties, fines, allow/prohibit the sale of certain types of goods. Thanks to this the economy of the country is prospering, because the income from taxes is accumulated in individual states and only a small percentage of the country goes to the capital, where if necessary it can be distributed among the regions or used for other purposes. This system also makes it more profitable to trade both domestically and internationally.
However, a significant disadvantage of this system is the discord between the regions. For example, at one time Texas wanted to secede. Plus lawyers have to “adapt” to the rules of each individual region, as do the citizens of the country. If in one state you could get a small fine for a violation, in another state you could end up in prison for the same violation.
