There's been some fairly dodgy journalism around this case due to the obvious bias on either side but I think I'm right in saying there's no actual law in place as of yet?
Also, not sure if anyone has even been arguing that it wasn't the state's decision but that doesn't completely absolve the church of responsibility.
There is no legislation as yet, which is what I said...the Constitution allows for legal abortion in certain circumstances due to the equal right to life of the Mother, but successive administrations have failed to enact the legislation to put those Constitutional Rights onto the Statute.
The responsibility ultimately lies with the People and Government of Ireland, as they have either voted in or denied several referendums on rights associated with abortion in Ireland. The Catholic Church has its opinion, just as other Churches have a different one, but ultimately this is an issue for the Government and the various referendums that have been voted on.
