In his political life, Lilar was a liberal senator of the Arrondissement Antwerp (1946–1971) and four times Minister of Justice (1946–1947, 1949–1950, 1954-1958 en 1960-1961).

As Vice-Premier, he was elected president of the Round Table in 1960 whose discussions lead to the independence of the Belgian Congo. A great humanitarian and defender of human rights, no death penalties were carried out under his terms as minister of justice.
