To set out the "once-only" principle for all administrative procedures while empowering citizens as the sole holders of information

"Once only" is the principle according to which any information should be requested from citizens one time only, whereby they are the sole holders of their data, regardless of which administration needs the information or for what process it is provided. The development of administration organised according to impervious, self-contained spheres has meant that over the years various uncoordinated parallel procedures have been created which require citizens to provide the same information, detail or document several times. The administration has scarcely endeavoured to strengthen the inter-operability of its procedures to save citizens from having to provide data they have already handed over. In order to achieve this, it is necessary to begin re-devising procedures as we began to detail in action 9.6, while digitalising them and establishing their inter-operability, starting from a fundamental basis: each citizen is the sole holder of their information, which they assign to the administration according to a mutual commitment to correct usage and the delivery of a public service.
