I'm Irish and the ruling relates to the double-irish tax break specifically, it's about marketing for this tax evasion tactic. It's a hot topic in Ireland; Ireland looks like one of the richest countries on Earth (by GDP) but most Irish aren't feeling this. It's the huge amounts of money flowing through this double-irish loophole that creates the false GDP number. The loophole should end and paying the tax means closing the loophole.
