From the Latin “decrētum” the decree entry originates, which means decision, order or official sentence; “decretum” comes from the neutral form of the participle of the voice “decernere”, lexically composed of the prefix “de” which indicates the direction of up and down, plus the verb “cernere” which means “to distinguish” a verb that comes from a Indo-European root. Decree can be defined as the decision or resolution of a president or head of state, court, judge or other type of authority, which communicates about any matter, matter or business. This decision generally applies to political and government characters. That is to say, that in a general sense it is that norm dictated by a certain figure of authority, with a particular purpose. It should be noted that a decree can also refer to everything that the Pope orders before a consultation with the cardinals.

Many times when speaking of a decree, it refers to an administrative act directed by the Executive Power, with a normative regulatory matter and a lower hierarchy than the laws. There are types of decrees such as the royal decree, which is the one that is approved by the Council of Ministers and is signed by the king of that nation. On the other hand, there is the decree law, which is the determination made by the government in certain circumstances or occasions.

In ancient times, the so-called “payment decree” arose that was sent to the treasurers so that the items paid according to the king’s orders were admitted in data in their accounts. Next, when speaking of the “Decree of Gratian”, which is written with an initial capital letter, also known by the name of “Concordance of the Discordances of the Canons” or “Harmony of the Discordant Canons”, allusion is made to the writing or book of Canon Law compiled by the Camaldolese jurist monk and professor of Theology at Bologna, Graciano or Franciscus Gracianus.
