Seanad candidate Jerry Beades owes €28,000 to Dublin City Council in fines relating to an unfinished apartment development.
The face of the New Land League, who rose to prominence last year when he supported solicitor Brian O'Donnell in his fight to stay in his luxury Killiney home, Gorse Hill, owes the significant levies in relation to a north Dublin site.
The site, at 21 and 27-29 Richmond Avenue, has been listed on the city's Derelict Sites register since 2012 and has been racking up fines since then.
It is classified as an "unfinished housing development", and as of last November, around €28,000 was owed in levies on the site, none of which have been paid to date.
In July 2012, Bank of Scotland secured judgment orders for €9.6m against Mr Beades in relation to loans to build the apartments. Four loans extended between 2005 and 2008 were to be repaid with the proceeds of the sale of the apartments.
"I would have finished the apartments in Richmond Avenue if the bank had given me another €2m that I needed to complete the job," he said when previously asked by the Herald about the site.
The apartments were due to be built on a site adjacent to a historic house with links to the 1916 Rising.
The Thomas Clarke house, 31 Richmond Avenue, was to remain at the site with Mr Beades seeking to develop apartment blocks alongside it.
The site is now used as a commercial base for Mr Beades' construction company. Mr Beades declined to comment as he was appealing a judgment linked to the site.
