Men who violated the Navigation Acts, after 1764, were not tried in a regular court. Instead they were tried in Admiralty courts. In these courts, violators were presumed to be guilty and did not have a jury to hear the case.
Prior to 1764, the people who violated these laws did get to have a jury trial and were presumed innocent. When the laws changed, the colonists argued that the men had a right to have a jury trial. They argued that their basic rights were being taken away without a trial by jury.
Plato says that art imitates the objects and events of ordinary life. In other words, a work of art is a copy of a copy of a Form. It is even more of an illusion than is ordinary experience.
