The ICCL have the exact same mentality as the ACLU. I'm sure they share a common history too. You can see what they say about themselves here -
http://www.iccl.ie/constitution/index.html - the Eight Amendment to the Irish Constitution is the 'Pro Life Amendment' (note they didn't use its title) - which passed but which was essentially reveresed by the Irish Supreme Court in the 'X Case'. The similarities to the United States experience are very telling, the activist judges especially, a lot of it like history repeating itself.
