That's good news. Iy would suggest they will need to return, at their own cost, to Germany for the court case. Is the the case, or did the offence take place on Irish territory, but in German airspace? Can the Germans pass it on to the Irish courts? Could they end up with a criminal case in one country and then a civil damages case in Ireland?
Escaping out of Berlin back to UK would not be cheap. I wonder what kind of 'stag night' the others had in Bratislava without a groom.
