"What matters is what's contained in the bill, and what's in the bill is dangerous," said Caroline Simons, a legal consultant to the campaign. "For the first time an Irish government is proposing to introduce a law that provides for the direct intentional targeting of the life of the unborn child."
The draft legislation will be discussed by the Irish parliament's health committee over the coming weeks before being presented to both houses of parliament. It is almost certain to be approved in the end, as the coalition government has a big majority.
Some lawmakers from the main coalition party Fine Gael are likely to vote against the bill, however. Their opposition is set to be expressed at their weekly party meeting Wednesday evening.
Anti-abortion protesters may also gather Wednesday.
Ireland's deputy prime minister, or tanaiste, Eamon Gilmore, reminded lawmakers Wednesday that a small number of pregnant women do find themselves in the awful situation where their life is in danger.
"Women have a right to know that if the worst happens, they will be able to have life-saving treatment," he said.
"Yesterday, the government made a decision that that right will now be vindicated."
