The administrative act produces effects for a period of  time  until  it  is  at  an  end  –  tempus  regit  actum. Publicity of acts constitutes a validity condition; no one  could  invoke  the  nemo  censetur  legem  principle.  Three  main  modalities  entail  the  end  of  the  effects: the act is at an end, falling into desuetude or repealed. There are also other cases, such as: a) repealing of the legal basis; b) ascertaining the unconstitutionality on the basis of article 147 par. (1) of the Constitution; c) adoption of a law for the rejection of an ordinance; d) issuance of a decision that declares  unconstitutional  the  law  for  the  approval  of an ordinance; e) inexistence and caducity of an ordinance; f) repealing of the repealed norms of ordinances; g) annulment of a normative administrative act; h) promulgation of the law before the issuing of the decision by the Constitutional Court; i) ending the  effects  of  a  governmental  decision,  following  the  removing  of  a  company  from  the  companies  registry; j) total replacement of the title and object of a regulation through the law for the approval of an ordinance. Accordingly, the cases of ending effects of administrative acts are wider than the three main modalities, as well as the institution of ending legal effects of normative acts is broader than the institution of repealing of those act.
