The famous Roman law that existed inAncient Rome and the Byzantine Empire over a thousand years in the period from VIII BC to the VIII century AD, formed the basis of the legal systems of European countries.
One of the essential attributes of Roman law is a veto, which is different to the "strong" and "weak."
With a weak veto Parliament / Internationalorganization only obliged to re-examine the bill. The strong veto, by definition, more difficult to overcome, so generally have the right president in developed countries (USA, Germany and others).
History veto dates back to the era of ancient Rome,when they were created national platform, designed to defend the rights of the lower strata of the population - the plebeians. Translated from the Latin veto means "forbidden". Therefore, as the name implies, it is right to limit anything. The legal system of the Roman Empire was the basis of many European legal systems, therefore limiting the use of the right is logical.
This right allows a single personor group of persons to unilaterally block the adoption of those or other written and oral decisions. That is, for example, if the adoption of the draft (regulations, resolutions and similar solutions) voted 30 people and only one spoke against it, vetoed the project will not be accepted and assigned a new date for a vote.
It is noteworthy that the vetounlimited number of times is entitled to any of the participants, the meeting of the Committee. Therefore, the general solution of the adoption may be delayed for many years, and eventually not even be accepted. The veto is widely used by international organizations in making decisions of any importance.
It is often said that, for example, insome of the UN meetings (NATO, the European Parliament and other international organizations), the representative of one of the countries used the veto power and the adoption of the document is locked.
Among the clearest examples of long-term use (into some extent on the verge of permanent) restricts this right, it may be noted Greece's position in relation to Turkey's intention to join the European Union. For the past 14 years, largely due to a Greek veto of the Republic of Turkey does not use explicit and imaginary benefits of joining Europe.
Also worth noting is "fresh" example of overlayingveto. It is the adoption of UN Security Council resolutions regarding the legality of the referendum in the Crimea. To be precise, the non-acceptance of an international instrument because of its blocking of the Russian Federation, as a permanent member of the UN Security Council. It is noteworthy that the representatives of the People's Republic of China abstained in the vote, which to some extent ensures a long discussion of the resolution.
