There is a certain degree of wiggle room even in the Dáil. The issue is that if a Bill imposes a kind of incidental charge on the State, under certain circumstances the Ceann Comhairle and Bills Office would allow it through the Dáil. My understanding of Standing Orders in the Seanad is that there is a little more wiggle room. Something like this would include a clear and significant obligation. It may not be very expensive but would include a significant charge and, therefore, it would have to be a Government Bill or would require a Government amendment to the Bill.
