The group was well-known for their 'annual champagne duels', involving well-shaken bottles of champagne aimed at each other from 10 paces apart; the winner of the duel is whoever first knocks off the opponent's top hat. Each dueller represents a differing view on a subject, and the winner's viewpoint would later be adopted as League policy. One such duel on 4 June 1975 between Hamilton and another League member decided the group's position on European Community membership in the membership of that year. Hamilton won the duel, announcing to journalists that the League "views with unabashed antipathy all forms of democracy, especially the referendum" and that "we oppose anything that is common, whether it be consultation of the common people or the Common Market".
