To Roman.Observer:
- legally possible: the Sky Europe B737 had been blocked, not seized, by Aéroports de Paris, and it was because of unpaid airport charges. This reason is valid and legal in almost any country in Europe. By the way, Eurocontrol has the legal possibility to do same if there are unpaid route charges.
- union trial / easyJet: the law that French "Office Central de Lutte contre le Travail Illegal" is not specifically French but an EU regulation. It states that when workers are based in a country X for more than some months (6? but I am not sure and no time to check), the social charges and taxes regarding such workers have to be paid in country X, whichever the country of the employer is. Ryanair was brought to the Court because it did not pay the charges/taxes in France but claimed to do so in Ireland - which by the way is not even correct as the "independent" pilots have to pay their charges themselves.
