The Government is being accused of sneaking in taxes over the summer months.
Fine Gael claims a range of so-called 'stealth taxes' are being implemented during the Dáil recess.
The Justice Minister is being singled out in Fine Gael's attack on what the party is describing as an "unfair and unflagged revenue generating exercise".
It says Dermot Ahern has taken advantage of the summer months to use statutory instruments that allow ministers to sign off on orders without going through the Oireachtas.
Some of these 'stealth taxes' include a €330 rise in the cost of becoming an Irish citizen; a €200 rise in the cost of a bar extension licence for weddings and functions; an increase in court fees; and a €20increase in land registry fees.
The opposition is calling for a review of the 1936 law which allows these increases to be passed.
