In "A Year and A Day" (series 2), a refugee peasant explains that, under English law, a peasant who escapes serfdom and lives in a city for "a year and a day" is a free man, provided the man lives openly, not in hiding. When Robin Hood helps the peasant move about the city, the Sheriff invokes "the law of hue-and-cry", explaining that any man within hearing must drop his chores and help apprehend the felon. In "A Christmas Goose" (series 3), a boy's goose nips a lord's horse so the lord is thrown. The lord condemns the goose to death – for his Christmas dinner. But Robin Hood counters that under English common law, an accused animal is entitled to a fair trial, the same as a human. While Robin Hood drags out the trial, Friar Tuck gets the cook drunk and switches geese. When the deception is revealed, the lord relents and pardons the goose. Two episodes, "Brother Battle" (#84) and "To Be a Student" (#90) emphasized the Catholic Church's struggle to educate commoners, and even the children of the Saxon serfs, despite laws forbidding the practice and in the face of opposition from the Norman nobility.
