Decree-Law on Administrative Modernisation
The Decree-Law no. 135/ 99, reviewed by the Decree-Law no. 73/2014, approved in May 2014, established important administrative modernisation measures, including the ‘once only’ principle, according to which the citizen must not be obliged to give the Public Administration the same document twice. The ‘once only’ principle leads to several standards, particularly relating to administrative communications.
