Finnish court accepts e-voting result, 2% lost

Nailor writes: Helsinki Administrative court accepted the municipal voting result despite the fact that 2% of votes that were cast were not counted at all. Court noted that the e-voting machinery has a feature, that should be considered as an issue . However, it also noted that "a little over two percent failure rate can not be considered as such as a proof that the voting official would have acted erroneously". Does this mean 98% of votes is enough to figure out what the rest 2% vote? Electronic Frontier Finland has a press release about the court decision (in Finnish).
