Germany has banned the use of voting machines which record the votes electronically only. Following is quoted from the source.
The German Constitutional Court upheld the first argument, concurring that the use of the NEDAP voting machines was unconstitutional. The Court noted that, under the constitution, elections are required to be public in nature and
that all essential steps of an election are subject to the possibility of public scrutiny unless other constitutional interests justify an exception . . . The use of voting machines which electronically record the voters’ votes and electronically ascertain the election result only meets the constitutional requirements if the essential steps of the voting and of the ascertainment of the result can be examined reliably and without any specialist knowledge of the subject . . . The very wide-reaching effect of possible errors of the voting machines or of deliberate electoral fraud make special precautions necessary in order to safeguard the principle of the public nature of elections.
So, is Germany now using paper votes only? Which other countries have banned electronic voting machines and on what grounds?
