6.—(1) An order under section 5 may include such transitional and consequential provisions as appear to the Government to be appropriate.

(2) Such a provision may, if the order so provides, take effect on the date on which this Act comes into operation or a later date.

(3) To the extent to which such a provision takes effect on a date that is earlier than the date of its notification in Iris Oifigiúil, the provision does not operate so as—

(a) to affect, in a manner prejudicial to any person (other than the State or an authority of the State), the rights of that person existing before the date of that notification, or

(b) to impose liabilities on any person (other than the State or an authority of the State) in respect of anything done or omitted to be done before the date of that notification.
