It is profoundly foolish and unnecessary to rely on the probity of a small collection of individuals at mulitple potential points of vulnerability in the voting procedure when a system should be used that in itself ensures much gretaer transparency. The very fact that we are being put in the position of having to trust people rather than procedures being put in place that would obviate that need, in this referendum and all elections, is suspicious in itself.
I don't know what the origin is of the Irish procedure in doing this but I would observe that it would be a useful final redoubt for the establishment if, over the past several decades, sinn féin or any republicans ever looked like getting enough votes to hold the balance of power in the country.
