Four people arrested during disturbances at a peace rally at Shannon Airport on 1 March were convicted at Tulla District Court today.
Charges against four other protestors have been dismissed as unproven. All eight people before the court were charged with engaging in threatening and abusive behaviour.
Two of those convicted - Robert Fulton from Salthill and Cliona Murphy from Woodsgift in Kilkenny - were fined €400 each.
Ciaran Hegarty from Togher in Cork was given the probation act and Nicholas Silva, a US cititzen living and studying in Galway and the only one of the eight to plead guilty, was fined €100.
All four have been bound to the peace and ordered to stay out of County Clare for two years.
Before convicting, Judge Joe Mangan said those who professed to seek peace in the world should begin by behaving peacefully at home.
