I am not sure how this helps the poster of this thread, because with a reading of 72 he is above what you suggest as the threshold for a court appearance anyway.
The figures that have been quoted for Ireland are not correct, there is a link below that shows what the actual limits and punishments are. I was part of the early discussions in advising the Irish government on the best way to proceed with reviewing their drink drive laws.
They quote blood readings, but in breath it is equivalent to a reading of 22-35 resulting in a fine and 3 points, 35-44 resulting in a 6 month ban and above 44 resulting in a court appearance and a 1 year ban, 44-67 is a 2 year ban and above that a 3 year ban.
The option of points is only available once in a 3 year period, and the readings and punishments are greater for new drivers in their first 2 years. So, yes, Ireland is a bit softer but not by much, and at the higher end they give out greater punishments than in the UK.
It seems inevitable that we will also reduce our legal limit to 50 in blood, (22 in breath) and there will be a debate as to the suitable punishment for breaking the new lower limit. On a personal note, I feel that the current minimum 12 months ban is too harsh for the lower limit because the risk to other motorists is lower than at the current limit, but I think that the Government will follow the Scottish model and leave the 12 month ban in place for the lower limit. There is no chance that the legal limit will come down, but the threashold for court will be raised to 60.
