The government has said a proposed bill to cap rents would be unconstitutional.
The People Before Profit Bill would cap rents at a quarter of median monthly household income.
The party has called on all landlords on the Government benches to recuse themselves from the vote.
Junior Housing Minister Peter Burke says the Government is opposing the bill:
"Aside from its technical and practical operational shortcomings, it would in all likelihood quickly face significant risk of legal challenge, and is likely to have severely detrimental effect on the supply of much needed rental property. The government is acutely aware that rents are very high in many areas, as a result of pent up pressures and supply constraint."
