The NSW opposition will refer Labor minister Frank Sartor to the Independent Commission Against Corruption (ICAC) in relation to a law he changed as planning minister.
Plans for a four-storey building overlooking Mr Sartor's home were dropped in favour of open space after he changed the law as planning minister, The Daily Telegraph reported on Tuesday.
Liberal frontbencher Anthony Roberts will refer the matter to ICAC on Tuesday, alleging the minister appeared to have benefited in relation to the development in Rocky Point Road at Kogarah in south Sydney.
In 2006, Newman's car dealership applied to Kogarah Council for a 74-unit development on the site adjacent to Mr Sartor's house.
The developers argued that under "existing use rights" they were able to build the residential block, even though the land was not zoned accordingly.

The following month, Mr Sartor abolished by regulation the concept of "existing use rights".
The developers dropped part of their plans, putting an open space next to Mr Sartor's home.
Mr Sartor, now Minister for Climate Change and Environment, has denied the law change was made to stop the development overlooking his house, describing the claims as "nonsense".
"The development did go ahead and it still overlooks our house," he told the newspaper.
