Is the system acceptable under freedom of association principles?
“Compulsory arbitration to end a collective labour dispute and a strike is acceptable if it is at the request of both parties involved in a dispute or if the strike in question may be restricted, even banned, i.e. in the case of disputes in the public service involving public servants exercising authority in the name of the State or in essential services in the strict sense of the term, namely those whose interruption would endanger the life, personal safety or health of the whole or part of the population.”
