The constitution plays a special role lives of societies and states. The term "constitution" is used even during slaveholding and feudalism. In Ancient Rome quite so called resolutions of the emperor. But what the constitution means presently? About it the speech will also go. The constitution - one of the most important achievements of democracy. Now almost all countries of the world, except for several absolute monarchies of Gulf States have the constitution. So, the constitution is the main normative legal act possessing legal properties by means of which on behalf of the people the basic principles of the structure of the state and society are established. It proclaims and protects: the rights and freedoms of the person and the citizen, the people - the only source of the power, restriction of the government with the right - and many other standard democratic values. It is accepted to call the constitution the Basic law. Why? Yes because this law has the highest validity in all system of legal acts. Other regulations which are accepted in our state, have to be guided by the Constitution and can't contradict it! If our Constitution guarantees everyone freedom of thought and the word, it means that NO other laws have right to introduce any restrictions on freedom of thought and the word, for example censorship. Also the Constitution of our country includes a certain set of values. If you attentively read the Constitution preamble, you can be convinced that it is based on such, for example, values as moral values: … "belief in good and justice"; the democratic: "approving the rights and freedoms of the person"; "reviving … statehood of Russia and approving firmness of its democratic basis"; the patriotic: "revering memory of the ancestors who transferred us love and respect for the Middle name"; the social: "approving … civil peace and harmony". The constitution proclaims that "The person, his rights and freedoms are the supreme value". Recognition, observance and protection of these rights and freedoms - a main goal of the Basic law. So let's observe all laws of the Constitution and then we will live in ideal, literally words, the state. After all the basic law is also accepted on purpose, to provide wellbeing and prosperity of the country.
