[1] Anthoni and the Minister of Interior Toivo Horelli were responsible for the deportation of 135 German refugees, including 12 Jews, Finland handed over to the Nazis in 1941–1943.

[6] In April 1942, Anthoni visited Berlin where he discussed with Heinrich Müller, Friedrich Panzinger and Adolf Eichmann over the ″Final Solution″ plan concerning the Jews of Finland.

[7][8] Although the Finnish government refused transferring its own Jewish citizens, Anthoni's trip caused a mass deportation of ″disagreeable aliens″ in June 1942.

The Minister of Interior Toivo Horelli and Anthony soon made a classified decision on the deportation of 27 refugees, of whom 8 were Jews.

[9] In late 1942, Anthoni asked Horelli to make a requisition for awarding the SS commander Martin Sandberger with the Order of the White Rose of Finland.

Poland and the Western Allies wanted Anthoni, Horelli and the State Police officer Ari Kauhanen to be included on the list of war criminals, but the Soviet Union never made a claim to the Finnish government.

Part of his reason for his acquittal was that Georg Kollmann, the sole survivor of the deportations, who lost his wife and child, forgave Anthoni and asked that he not be punished.

[5][13][14] Anthoni worked his last years as a lawyer for the mineral company Oy Lohja Ab, owned by the prominent Finnish Nazi Petter Forsström, who'd served time in prison for treason after being convicted of working with the Nazis after Finland switched sides.
