For instance, a law against protesting

“That at which the entire body of the citizens aims intellectually and emotionally is more certainly judged as to its truth and more diligently noted as to its common utility. For a defect in some proposed law can be better noted by the greater number than by any part thereof, since every whole, or at least every corporeal whole, is greater in mass and in virtue than any part of it taken separately. Moreover, the common utility of a law is better noted by the entire multitude, because no one knowingly harms himself. Anyone can look to see whether a proposed law leans toward the benefit of one or a few persons more than of the others or of the community, and can protest against it. Such, however, would not be the case were the law made by one or a few persons, considering their own private benefit rather than that of the community.” – Marsilius dei Mainardi, The Defender of Peace (trans. Gewirth)
