Scherner was awarded the Iron Cross second class and the Wound Badge in black and subsequently discharged from the military on 30 March 1920, with the rank of Oberleutnant.

As an SS garrison commander of Prague, between January and September 1941, Scherner supervised preparations for the establishment of a Waffen-SS training camp at Benešov, Bohemia.

Klare alleged that Scherner owed him money and had embezzled food stuffs and inappropriately used his service vehicle.

He gets close very quickly to every person, but unfortunately does not possess the ability to recognise [sic] and comply with the prescribed boundaries that apply to him in his official position towards subordinates."

Scherner was sentenced to 14 days of, Stubenarrest, house arrest but this punishment was postponed until after the war and ultimately never imposed.

Police battalions, commanded by Scherner, encircled the ghetto and announced all Jews were to required to register and would be killed if they did not comply.

[9] Scherner was responsible for the deportations to the Bełżec extermination camp, the mass shootings in Tarnów and all 'evacuations' that took place during his time there - including Aktion Krakau.

His position afforded him a great deal of authority in many areas, as the title of SS and Police Leader was conferred to high-ranking Nazi Party members, reporting directly to Himmler's deputy.

[10] Scherner was transferred to Dachau in April 1944 and appeared before an SS Court (the dreaded Hauptamt SS-Gericht) on 16 October 1944.

As a result, Scherner was demoted from SS-Oberführer der Reserve (Senior Colonel or Brigadier) in the Waffen-SS (1937-1944) to SS-Hauptsturmführer der Reserve (Captain) and transferred to the Dirlewanger Brigade (formally the 36th Waffen Grenadier Division of the SS) under SS-Oberführer Dr. Oskar Dirlewanger.

He was found dead shortly before the war ended in a wooded area near Heidesee between Märkisch Buchholz and Halbe.
