Criminal law is divided between federal and state systems, and more than 95 percent of all criminal prosecutions occur in state courts under state statutes. Penalties for the same conduct vary dramatically by jurisdiction — a marijuana possession charge that is a minor infraction in one state may still be a felony in another. Sentencing guidelines, mandatory minimum rules, bail procedures, diversion program availability, and expungement eligibility are all set at the state level. Whether a conviction results in probation or a mandatory minimum sentence often depends more on which state filed the charges than on the underlying conduct. Collateral consequences of a felony conviction — effects on professional licenses, firearm rights, public benefits, and voting rights — also differ by jurisdiction.
