A passion for litigation.
“I have a passion for litigation of any kind. Litigation is like a card game: you have to play with the cards you are dealt. Then, everything depends on your competence, your opponent’s competence and of course the judge’s competence. But your duty is to do everything possible to defend your client’s interests and to fight to the end.

But Spyridon speaks with equal passion about his role as an advisor: “Today, half of the gross national product disappears into the state coffers. It is logical that taxpayers are looking for ways to escape such a high tax burden on their income and assets. But it is important to do it in a legal way.
