To allow for an effective implementation of the provisions on the language, as per the regional law no. 26/1997 and the national law no. 482/1999, the Sardinian Autonomous Region arranged for a commission of experts to elaborate a standard capable of overcoming the hurdle posed by the dialectal differences and thereby providing a unified writing system. A first proposal (the LSU: "Limba Sarda Unificada", published on 28 February 2001) was tabled which identified a model language of reference (based on the analysis of local varieties of Sardinian and on the selection of the most representative and compatible models) so as to guarantee the necessary characteristics of certainty, coherence, univocity, and supra-local diffusion. The people appointed for the task were Eduardo Blasco Ferrer, Roberto Bolognesi, Diego Salvatore Corraine, Ignazio Delogu, Antonietta Dettori, Giulio Paulis, Massimo Pittau, Tonino Rubattu, Leonardo Sole, Heinz Jürgen Wolf, and Matteo Porru acting as the Committee's secretary. This study, although scientifically valid, has never been adopted at an institutional level: critics argued that it was an "imposed" and "artificial" language based on the mediation between the central-northern varieties.
