Judges are not designers - official

According to a Register report concerning a court case over voter verifiable trails for touch screen voting machines, judges do not see their role as being to opt for a better or preferable machine design:

US District Judge James Cohn [...] did acknowledge that a voter-verifiable receipt would be preferable, [but] he noted that it was his job to rule on the issue of equal protection that Wexler raised, not to evaluate the design of the ballot machines.
