The second appeared in 1815. After 1813 the government in The Hague were not indifferent to Veranneman's constitutional ideas. He was one of a small group of constitutional lawyers from the south invited to draft a preliminary proposal for a constitution. In the end other ideas prevailed, however, and the United Kingdom of the Netherlands ended up with a single unitary constitution which at the time was considered progressive (though the south would break away just fifteen years later). Veranneman was dissatisfied with the constitutional settlement of 1815. In order that his own ideas might become better known and, perhaps, yet have an influence, he published a booklet entitled "Projet de constitution pour les provinces de la Belgique, ci-devant Autrichienne" ("Constitution Project for the Belgian provinces, formerly Austrian [provinces]"). However, his earely death left him without very much time to promote and defend his ideas.
