(Referenda)
1. Upon a proposal submitted by the Assembly of the Republic or the Government in relation to matters
that fall within their respective competences, in the cases provided for and as laid down in the
Constitution and the law, the President of the Republic may decide to call upon citizens who are
registered to vote in Portuguese territory to directly and bindingly pronounce themselves by referendum.

Republic. Such initiatives shall be submitted and considered under the terms and within the time limits
laid down by law.
3. Only important issues concerning the national interest which the Assembly of the Republic or the
Government must decide by approving an international convention or passing a legislative act may be the
object of a referendum.
