Ireland has a tax on non-staple foods (VAT). The Irish suit was asking the court to rule that Subway bread was a staple food and as such, not subject to the tax. Because the sugar content exceeded the definition for bread, the court ruled that it was subject to that Value Added Tax. I don't think our US Supreme court would have reason to consider such a case because our laws do not add an extra tax to pastries, ice cream, chocolate, etc.
