Full of drive and enthusiasm, Falsen, aged 26, stormed into Follo's elite as a magistrate in 1808. He bought the farm Vollebekk. Originally this was a small farm. In a few years, Falsen Vollebekk developed into an estate with nearly 1,500 acres of cultivated land and a total of 9 buildings, of which a dominant main building with its own office wing. Most likely, it was here that Falsen and his friend, fellow student and collaborator Johan Gunder Adler sat when they formed the draft of Norway's constitution.
Vollebekk was very centrally located in Follo. Therefore, this was a natural place to have the magistrate's office. The then main road south / north through Østfold, Follo and Akershus, the so-called "Fredrikhaldske Kongevei", ran through the yard at Vollebekk. The same can be said about east / west – the axis from the inner villages to Drøbak (De drøy bakken).
Falsen and Adler already had a draft constitution ready in outline form in February 1814. This draft became very important during the national assembly at Eidsvold which met on 10 April 1814. Here Christian Magnus Falsen became leader of the constitutional committee. With his strong will and ongoing style, he became a driving force in the committee's work.
Falsen also soon became the leader of the majority in the Riksdag who was in favor of full independence. In this he became a main opponent of Count Wedel Jarlsberg, who wanted union with Sweden.
Falsen finished his development work of the young, new Norway in 1814 as an adviser to the Danish king Christian Fredrik during the negotiations in Moss in August 1814. He was among those who advised the king to continue the war.
Whether it was burdensome debt or "hatred of the Swedes" that drove Falsen west to the office of magistrate in Nordre Bergenhus county is not well known. In many ways, the disappointment over the Moss Convention appears as a driving force to get out of the center of events. Until then, Falsen had been very central in a decisive phase for Norway and the Nordic region.
We see less of the strong, confident Falsen in his later years. When he died of a stroke aged just 47, he was a Supreme Court justice, living in Oslo where he is buried.
The six years Christian Magnus Falsen lived and worked in Follo, in many ways characterize the dominant image of the man who many believe can rightly be called the "Father of the Constitution".
It is difficult to form an overall picture of Christian Magnus Falsen. It can be documented that he was an active spy for the Danish king before 1814. He was also later accused of espionage.
He acted for a long time and clearly as farmer-friendly and a man of the common people. Then he appears later as the sovereign representative of the upper class and the aristocracy, almost with contempt for "the people".
He referred to the independent men at Eidsvold (of which Falsen became an undisputed leader): "as the glorious Falsen". The union men at Eidsvold – who were therefore opponents of Falsen – were far from positive in their comments. Jacob Aall has depicted Falsen in rather gloomy colours: – "His demeanor was unpleasant, his speech harsh and offensive, his expression dark and harsh in the Assembly".
Halvdan Koht writes: And even 100 years after his death, there is a burning question in our history: Was he a traitor? Or was he done a bloody wrong? Was there a connection in his apparent contradictions? Or did he really change ideals?
Falsen's acquisition and development of Vollebekk may well be an underlying reason why the Storting in 1859 decided to place the newly established "Høiere Landbruksskole" precisely at Vollebekk in Ås (now the University of Life Siences.
