Florida Central Voter File
Criminal law is the body of law that relates to crime. It regulates social conduct and proscribes threatening, harming, or otherwise endangering the health, safety, and moral welfare of people. It includes the punishment of people who violate these laws. Criminal law differs from civil law, whose emphasis is more on dispute resolution and victim compensation than on punishment.
Loss of rights due to felony conviction
The Florida Central Voter File was an internal list of legally eligible voters used by the US Florida Department of State Division of Elections to monitor the official voter lists maintained by the 67 county governments in the State of Florida between 1998 and January 1, 2006. The exclusion of eligible voters from the file was a central part of the controversy surrounding the US presidential elections in 2000, which hinged on results in Florida. The 'Florida Central Voter File' was replaced by the Florida Voter Registration System on January 1, 2006 when a new federal law, the Help America Vote Act, came into effect.
Loss of rights due to felony conviction takes many forms. In the United States this includes disenfranchisement, exclusion from Jury duty, and loss of the right to possess firearms.
The term crime does not, in modern times, have any simple and universally accepted definition, but one definition is that a crime, also called an offence or a criminal offence, is an act harmful not only to some individual, but also to the community or the state (a public wrong). Such acts are forbidden and punishable by law.
