A national liquor group is facing a major lawsuit in the Federal Court following an ABC investigation into allegations that fake scotch has been sold around Australia.

D'Aquino Bros Pty Ltd, and seven related parties, including Mr Liquor, a Sydney retail store, have been accused of selling alcohol wrongly labelled as scotch — in breach of Australian and international trademark laws.

The claims have been brought by the Scotch Whisky Association (SWA), which represents 120 registered distilleries.

The industry exports around $4 billion, or 1.2 billion bottles of Scotch a year.

If D'Aquino Bros is found to have infringed trademarks, it will be legally barred from using the protected name "Scotch" on its alcohol range.

Where the 'Scotch' whisky was sold J.B.R Scotch Whisky —Mr Liquor, Parramatta Westfield, NSW The Clansmen Scotch Whisky — Mr Liquor website, Mr Liquor, Circular Quay, NSW The Black Scot Scotch Whisky — Mr Liquor, Parramatta, NSW, D'Aquino Liquor, Orange, NSW, Valore Cellars, Parramatta, NSW, Champion Liquor Store, Caboolture, QLD

The SWA is also seeking an award of damages for "acts of trademark infringement", and further allege "flagrant" conduct which involves "consumers being deceived" by fake products.

Three brands of whisky sold online and in two states — including "The Black Scot", "The Clansmen", and "J.B.R Scotch Whisky" — were named in the court papers.

A spokesperson for the SWA said it took the protection of Scotch Whisky "extremely seriously".

"Wherever the legal requirements that govern the production of Scotch are not being upheld, we will take action," the spokesperson said.

Company representatives at D'Aquinos Bros and Mr Liquor were approached for comment about the court case.

The ABC understands that if the Federal Court issues an injunction, D'Aquinos would be unable to sell products labelled "Scotch" and "Scotch whisky" to pubs, clubs and bottle shops around Australia.

Earlier this month, the ABC reported that D'Aquino's brand "The Black Scot" had been identified in laboratory tests as a fake scotch as the tests showed the product did not originate in Scotland.

When approached by ABC journalists to comment, employees at the company told the ABC that its scotch and tequila products were manufactured locally.

The ABC also understands the Australian Competition and Consumer Commission and the NSW Food Authority are also reviewing allegations about fake tequila brands raised in the ABC's earlier reports.

A first hearing has been fixed in the Federal Court Victoria Registry for August 3.
