Here’s the reason the Dublin count has been releasing seruptious figures, is that they were not allowed to release figures before 9pm under European electoral law. Mark Coughlan at Irish Election explains:
Two of the groups involved had threatened to call in adjudicators from the European Commission if the count was to go ahead without the total for each round being publicly announced. The officials are not allowed to release such information before 9PM Irish time under European law, but appeared to have skirted around that by counting and releasing information unofficially. The groups who had threatened to call in the commission were placated by being given their first count totals.
It seems to me that in this instance, the European Commission is moving to prevent a problem that barely exists: avoiding the situation where the differential in national voting days adversely affects outcomes elsewhere in Europe?
