You could check that the vote adds up, but you cannot check that the vote are correct. Since Voatz is basically a private blockchain, there is no way to check that the blockchain was tampered with, or even saved the correct votes, before the it has been made public (which will be after the vote). The only way would be to have a mechanism for people to check if there vote was correctly saved at any point. And this is a very big problem, has having a way to know who vote for who in a democracy is a very very very big no no.
