The Supreme Court's seven justices announced their findings on Wednesday after dismissing an argument from the Scotch Whisky Association (SWA) that minimum unit pricing (MUP) is "disproportionate" and illegal under European law.
The UK Supreme Court has today ruled that minimum unit pricing for alcohol in Scotland, which was passed overwhelmingly by the Scottish Parliament in 2012, can now proceed.
The move is a response by the Scottish Parliament to tackle the nation's level of drinking by raising the price of cheap, super-strength alcohol.
The Scottish government said it was a "landmark moment" for public health and that the measure would be introduced as quickly as possible.
It marks a significant blow to the drinks industry's opposition to minimum pricing on drinks and may set an important precedent.
The ruling clears the way for the Scottish and Welsh governments to introduce a minimum unit price for alcoholic drinks, which is likely to be set at 50p a unit, and will increase pressure on English ministers to follow suit.
"In a ruling of global significance, the UK Supreme Court has unanimously backed our pioneering and life-saving alcohol pricing policy".
"This is vital in order that the jobs and investment the industry provides in Scotland are not damaged".
