Politicians with property portfolios should not be allowed to vote on housing policy, according to Rory Hearne.
The housing expert was speaking following Robert Troy's resignation from his position as Junior Minister in the Department of Business.
The Fianna Fáil TD was facing growing criticism over his failure to fully declare his property interests in the Dáil register.
The Longford-Westmeath representative owns of part-owns 11 properties around the country – nine of which are rented out.
In his resignation letter last night, he insisted he is “not a person of privilege and I have not been brought up with a silver spoon in my mouth.”
He said he bought his first house at the age of 20 and claimed he has “worked for all I have”.
Maynooth Professor Rory Hearne said there is a “real issue” with politicians “treating housing as an investment rather than a home.”
He noted that former housing ministers Alan Kelly and Simon Coveney are both landlords and at least 80 TD and Senators have officially declared property interests.
“It is a potential conflict of interest when you’re making policy decisions and you are deciding on what housing policies to introduce while also benefitting from those policies,” he said.
"When you look at what the Government has done - successive Governments over the last ten years in particular - I have made the point over and over that they have made policies largely in favour of what we call turning housing into an investment.
“In favour of landlords, in favour of investors and in favour of developers.”
He stopped short of calling for a blanket ban on TDs owning property portfolios – but questioned whether they should be allowed to vote on housing legislation.
“I do think there is a real issue around this conflict of interest of owning multiple properties,” he said.
“Maybe we need to look at clear decisions on housing policy. For example, legislation in relation to evictions, legislation in relation to rent caps; those TDs, should they be allowed to vote in that? Should they absent themselves?”
Deputy Troy resigned his junior ministerial position after the Green Party leader Eamon Ryan warned his failure to declare his properties to the Dáil "can’t be tolerated".
Minister Ryan has called for SIPO and the Oireachtas to investigate.
