I like to think this doctor goes up to eleven.

Full face tattoo and getting multiple people on board might do the trick for however long until additional markers are found for the edge case. I think clown makeup would do better since it varies day to day.

If this becomes precedent and enforced the whole Irish tax dodging method becomes moot, puting Ireland on par with other EU nations. If this is a high enough fine it will have long term ramifications.

The main issue to me is, big companies will find the next best thing and continue with unethical accounting, outside of the EU.
