My father was enraptured on finding me freed from the vexations of a criminal charge, that I was again allowed to breathe the fresh atmosphere and permitted to return to my native country.
Criminal court cases are held very similar to that of the United States criminal court cases. There is one judge and an appointed jury. The jury in Victor's case came to a unanimous decision that he was innocent.
It seems that the aristocratic party tended to favor those of high rank and often freed them disregarding any factual evidence (European Romantic Review). Mary Shelley may be suggesting that Victor's privileged rank may be the reason he was set free.
