Plaid Cymru AM Rhodri Glyn Thomas said his party would not be voting to pass the council tax benefit regulation unless they included a "sunset clause".
Mr Thomas was addressing Leader of the House Jane Hutt on 4 December 2012 following her business statement which included the government's intention to suspend standing orders to debate the regulations on 5 December 2012.
He said the government had left the matter to the "last minute" as they "wanted to argue with Westminster and ignored the needs of the vulnerable and poor in Wales".
The minister responded that the business committee had discussed the regulations.
She blamed the UK government for failing to release the necessary figures to the Welsh government.
"We are in the same position as Scotland and Northern Ireland.
"[This] will be debated tomorrow thoroughly."
