Ryanair chiefs are furious over a raid by French gendarmes at his offices at the Marseille-Provence airport and Thursday.
The company claims gendarmes prevented crew members from getting access to “weather information, passenger updates and flight information”.
The company has filed formal complaints with the European Commission, the Irish government in Dublin as well as the French embassy in Dublin, slamming the action as an “unjust intrusion”.
“It is unacceptable that a European airline that conforms perfectly with European legislation surrounding employment legislation is being unfairly and illegally interfered with by magistrates and the local Gendarmerie in Marseille,” a statement from the airline said.
The company also accused the French government of double standards.
“Air France and the French government would not accept this treatment of its facilities at London Heathrow or other European airports where Air France overnights aircraft and crews, who continue to pay their taxes in France because they are employed on French contracts and are flying on French-registered aircraft,” Ryanair’s statement read.
The French investigation into Ryanair is similar to the one which saw the firm ordered to pay €9 million damages in October 2013.
In that instance a French court ruled that Ryanair had illegally registered staff based at Marseille airport in Ireland in order to save money on payroll and other taxes.
The Ryanair case centred around a facility operated by the company at Marignane, where it had based four planes and 127 employees without applying French labour law or filling out tax declarations in the country.
Ryanair argues that Irish law should have been applied as it did not have a permanent activity in the area and its employees took their orders from headquarters in Dublin.
“Ryanair crews were correctly working under Irish contracts of employment and paying Irish social insurance in accordance with the applicable European employment and social security laws,” the company said at he time.
The Irish airline appealed the verdict.
