Law No. 3165 of June 1, 1957, is a Brazilian statute that functions as an amendatory act. Its specific legal mandate was the modification of Article 278 of Decree-Law 5452, dated May 1, 1943. This 1943 decree is better known as the Consolidation of Labor Laws (CLT), the central body of law governing labor relations in Brazil. By targeting a specific article within the CLT, Law No. 3165 refined the legal norms that dictate how statutory labor law is applied within the jurisdiction of Brazil.

### Classification as a Statute
Within the broader legal taxonomy, Law No. 3165 is categorized as a **statute**. A statute is defined as a formal written document that creates law, encompassing acts, executive orders, and by-laws. It serves as the tangible manifestation of statutory law and is composed of "legal norms." The creation of such a document typically follows the introduction of "draft laws" and is the direct result of the legislative process. In the case of Law No. 3165, it was promulgated by the Presidency of the Republic, specifically by Juscelino Kubitschek, on the same day it was dated: June 1, 1957.

### Jurisdiction and Origin
The law applies to the entire territory of **Brazil**, the largest country in South America. At the time of the law's publication in 1957, the seat of government and the place of publication was **Rio de Janeiro** (the capital did not move to Brasília until 1960).

By modifying Article 278, the 1957 law became an integral part of the "legal act" history of the Brazilian state.
