Edward was responsible for implementing royal justice through his network of judges and officials. It is uncertain to what extent Edward took a personal interest in dispensing justice, but he appears to have involved himself to some degree during the first part of his reign, and to have increasingly intervened in person after 1322. Edward made extensive use of Roman civil law during his reign when arguing in defence of his causes and favourites, which may have attracted criticism from those who perceived this as abandoning the established principles of English common law. Edward was also criticised by contemporaries for allowing the Despensers to exploit the royal justice system for their own ends; the Despensers certainly appear to have abused the system, although just how widely they did so is unclear. Amid the political turbulence, armed gangs and violence spread across England under Edward's reign, destabilising the position of many of the local gentry; much of Ireland similarly disintegrated into anarchy.
