Another De Facto Discrimination Case

I love a good de facto discrimination case.  Whenever one starts up, I think, "this is the one that's going to clarify all the GATT non-discrimination standards."  That hasn't happened yet, but I keep hoping, and here's another case with potential:

Brazil will ask the World Trade Organization to open a dispute panel over European Union poultry regulations it considers illegal, a senior government official told Reuters on Friday.

"We've concluded that we have a strong case and will proceed," said Carlos Marcio Cozendey, head of the foreign ministry's department of economics.

...

Brazil's poultry exports are the largest in the world and generated revenues of around $7 billion in 2008, before the financial crisis tempered global demand.

The EU, which adopted new regulations in May restricting the sale of certain thawed poultry products, is Brazil's third-largest market.

Brussels says that the measures apply also to its own poultry producers. But Brazil argues they discriminate against non-EU suppliers, who mostly ship frozen, not fresh poultry.
