A High Court challenge to the Children's Referendum is going ahead this afternoon.
Mark McCrystal, an engineer from Kilbarrack, Dublin, claims the Government is distributing a booklet that is designed to influence the electorate in favour of a Yes vote in the November 10 referendum.
Mark McCrystal says the Government is spending €1.1m of public money on what he claims is a one-sided information campaign.
His particular concern is the referendum's potential impact on parental rights.
When the case was before the court last week, senior counsel for the state, David Hardiman sought more time to engage an independent observer to comment on the literature.
Today when the state tried to put the case back until tomorrow, senior counsel Richard Humphreys for Mark McCrystal said the matter was extremely urgent from their point of view.
He said an expert has been looking at the literature since last Friday and he could see no reason for further delay, especially as the disputed material is still being distributed.
High Court President Nicholas Kearns agreed and set the hearing for 2pm today.
