The development of new and bigger databases on law production fostered the study of legislative behaviour. This happened not only in the traditional stage of congressional politics, but also, in the European Union and country levels. As a developing reality, still several countries do not have accessible legislative data, and Portugal counts as one of these examples, this database was constructed with this in mind. The time covered here comprises the period of 1982 to 2009 and covers all the legislative initiatives and approved laws that were proposed and enacted by the Portuguese Parliament and the Council of Ministers. Because of the institutional information, the detailed features of each one of the observations (legislation), the extended time-period and of the incorporation of variables potentially strategic, this database can be useful for a wide range of Academics.
