Adolf Süsterhenn submitted to the Advisory State Assembly a draft constitution, which was passed after several rounds of negotiation on 25 April 1947 in a final vote, with the absolute majority of the CDU voting for and the SPD and KPD voting against. A point of contention involved the draft constitution providing for separate schools based on Christian denomination. On 18 May 1947 53% of the electorate adopted the Constitution for Rhineland-Palatinate in a referendum. While the Catholic north and west of the new state adopted the constitution by a majority, the majority in Rhenish Hesse and the Palatinate voted against. On the same date the first elections took place for the state parliament, the Landtag of Rhineland-Palatinate. The inaugural assembly of parliament took place on 4 June 1947 in the large city hall at Koblenz. Wilhelm Boden was elected the first minister-president of Rhineland-Palatinate. Just one month later, Peter Altmeier succeeded him.
