It was never going to come into law yesterday.
It would still have to be passed by the Dáil before it would do so. To be honest, it's an extremely long bill with everything that's in it, it's not something that'll be passed overnight. Also when you think of the current time, with the budget looming, the same sex marriage legislation etc. and most importantly the election early next year, it's likely to be delayed substantially even if it was published yesterday.
