Scenаriо: A prоperty dispute аrises between twо neighbors, involving а claim worth several thousand dollars. The case is set to go to court, and one of the parties requests a jury trial, arguing that the issue involves significant property rights and financial value. However, the judge refuses the request, stating that the matter is not substantial enough to warrant a jury and will instead be decided solely by the judge. The defendant argues that their right to a jury trial in civil cases is being denied and that they have the constitutional right to have the matter resolved by a jury of their peers. Which amendment could they cite to support their demand for a jury trial?
