The
Reichstag Fire Decree, which had been in force since 28 February 1933, had contained in § 5 a list of crimes for which the death penalty was to be imposed instead of life imprisonment as before. The Law on the Imposition and Execution of the Death Penalty, passed by Hitler's government on 29 March on the basis of the
Enabling Act, extended the period of validity of this § 5 retroactively to 31 January 1933, thereby breaking the principle of the prohibition of retroactivity of criminal laws (
Nulla poena sine lege) guaranteed in Article 116 of the
Weimar Reich Constitution. It could thus be applied to van der Lubbe, who had confessed in court to having set fire to the Reichstag on 27 February. The Lex van der Lubbe allowed
hanging as a method of execution; whereas according to the specifications of the
Reich Penal Code valid until then, the death penalty had been "to be carried out by beheading alone". ==History==
