ballot and the keeping of the secrecy of elections are explicitly spoken of in § 35.2 sentence 1 of the Federal Electoral Act. The other principles of electoral law are regulated in § 1.1 sentence 2 of the Federal Electoral Act. They therefore certainly also apply to the deployment of voting machines in the elections to the German Bundestag. Finally, the legislature provided in § 35.3 sentence 1 no. 6 of the Federal Electoral Act that the Federal Ministry of the Interior may regulate the particularities in connection with the elections brought about by the use of voting machines. This provision forms not only a sufficient normative basis in order to account for the constitutional particularities of the deployment of computer-controlled voting machines. It also makes it recognisable for citizens that an election with voting machines may entail modifications in comparison with the classical ballot box election. It is not constitutionally required that all details of the content of a legal ordinance can be derived from the respective basis for the authorisation. The latitude which can be granted to the institution adopting the ordinance in this respect is also to be measured accounting for the complexity of the material and the dynamics of development processes in voting machines. The parliamentary legislature is hence certainly not constitutionally obliged to make detailed regulations for the deployment of electronic voting machines. 2. § 35 of the Federal Electoral Act is compatible with the principle of the public nature of elections. 142 a) It is not constitutionally objectionable that § 35.1 of the Federal Electoral Act permits voting machines “in place of voting slips and ballot boxes”. For § 35.1 of the Federal Electoral Act does not rule out with this wording the approval and use of voting machines with control devices which record the votes in addition to (electronic) recording in the voting machine in a manner controlled by the voter. According to the systematic status of § 35.1 of the Federal Electoral Act, the words “in place of voting slips and ballot boxes” refer to the classical election procedure set out in § 34 of the Federal Electoral Act in which exclusively official voting slips and ballot boxes are used. § 35.1 of the Federal Electoral Act, by contrast, does not rule out the adoption of provisions which provide for devices for a verifiability of the election result that is independent of the electronic recording and evaluation of votes. 143 b) It is unobjectionable for the principle of the public nature of elections contained in § 35 of the Federal Electoral Act to not be explicitly listed once more as a precondition for the authorisation and use of computer-controlled voting machines. These requirements emerge directly from the constitution, and hence are also binding on the institution adopting the ordinance in lending concrete form to § 35 of the Federal Electoral Act. Independently of this, it also emerges from other provisions of the Federal Electoral Act that the use of voting machines is only permissible if the principle of the public nature of elections is adhered to. § 31 of the Federal Electoral Act determines that the election act is public. § 35.3 sentence 1 no. 4 of the Federal Electoral Act permits regulations to be made on the open testing of a voting machine prior to its use. 144 31/37
