US businessman Donald Trump has lost a legal battle in Scotland to prevent the construction of an offshore wind farm he says will spoil the view from his luxury coastal golf resort.
Judge Raymond Doherty at the Court of Sessions in Edinburgh dismissed the petition by Trump International Golf Links and The Trump Organization to declare government approval for the farm illegal.
The Scottish government granted approval for the STG230 million ($A423.88 million), 11-turbine wind farm in Aberdeen Bay, off the north-east coast of Scotland, in March.
The Trump Organization said it was reviewing the judge's decision and considering its legal options. The ruling had "not altered our unwavering commitment to protect our investment in Scotland", it said.
Trump previously threatened not to proceed with his own plans for another hotel and more holiday homes at his golf resort, on which he has reportedly already spent STG750 million pounds, if the wind farm is allowed to go ahead.
He has been called a "bullyboy billionaire" by Scottish environmental campaigners and Aberdeen locals, who had launched their own legal challenges to prevent him building the resort on a pristine stretch of coastline.
Environmentalists and the Scottish government welcomed Tuesday's ruling.
"Donald Trump is a man who actually peddles the paranoid fantasy that climate change is a communist conspiracy," said Patrick Harvie, a Green member of the Scottish parliament.
"Scotland can't afford to waste another second on him."
