compensated for by sample devices in the context of the type approval procedure or
in the selection of the voting machines specifically used in the elections prior to their
deployment being subjected to verification by an official institution as to their compliance with certain security requirements and their proper technical performance. The
monitoring of the essential steps in the election promotes well-founded trust in the
correctness of the election certainly in the necessary manner that the citizen himself
or herself can reliably verify the election event.
For this reason, a comprehensive bundle of other technical and organisational security measures (e.g. monitoring and safekeeping of the voting machines, comparability
of the devices used with an officially checked sample at any time, criminal liability in
respect of election falsifications and local organisation of the elections) is also not
suited by itself to compensate for a lack of controllability of the essential steps in the
election procedure by the citizen.
126
Accordingly, neither participation by the interested public in procedures of the examination or approval of voting machines, nor a publication of examination reports or
construction characteristics (including the source code of the software with computercontrolled voting machines) makes a major contribution towards ensuring the constitutionally required level of controllability and verifiability of the election events. Technical examinations and official approval procedures, which in any case can only be
expertly evaluated by interested specialists, relate to a stage in the proceedings
which is far in advance of the ballot. The participation of the public in order to achieve
the required reliable monitoring of the election events is hence likely to require other
additional precautions.
127
c) The legislature can permit exceptions to the principle of the public nature of elections to a restricted degree in order to bring other constitutional interests to fruition, in
particular the written principles of electoral law from Article 38.1 sentence 1 of the Basic Law. For instance, restrictions of public monitoring of the ballot with postal voting
(§ 36 of the Federal Electoral Act) can be justified with the aim of achieving as comprehensive participation in the elections as possible, thereby complying with the principle of generality of elections (see BVerfGE 21, 200 (205); 59, 119 (125)). When deploying computer-controlled voting machines, however, no contrary constitutional
principles are recognisable which are able to justify a broad restriction of the public
nature of elections and hence the controllability of the election act and the ascertainment of the results.
128
aa) Where the deployment of computer-controlled voting machines aims to rule out
inadvertent incorrect markings on voting slips, unwanted invalid ballots, unintentional
counting errors or incorrect interpretations of the voters’ intention when votes are
counted (see Schreiber, Handbuch des Wahlrechts zum Deutschen Bundestag, 7th
ed. 2002, § 35, marginal no. 2) which repeatedly occur in classical elections with voting slips, this serves the interest of the implementation of the equality of elections under Article 38.1 sentence 1 of the Basic Law. What weight attaches to this purpose
