Defendants charged with capital felony offenses (i.e., offenses for which the death penalty might be imposed as a sentence) are entitled to have their cases heard by a jury of twelve persons who must unanimously agree as to the issue of guilt before returning a conviction. Defendants charged with non-capital felonies and misdemeanors may have their cases heard by as few as six jurors who, depending on the jurisdiction and the size of the jury actually impaneled, may return a conviction on a less than unanimous vote. The right to trial by jury is generally not afforded to defendants charged only with infractions or petty offenses. Defendants charged with felonies or misdemeanors that actually result in confinement to a jail or prison are entitled to the advice and representation of a court appointed counsel (see USCA.Const.Amend.6). Defendants charged with infractions or misdemeanors that do not result in incarceration are not entitled to court appointed counsel.

Accused felons must generally be present during their trials, while accused misdemeanants may agree to waive their right to be present. The testimony of defendants and witnesses may be impeached on the ground of a former felony conviction. But a misdemeanor is not considered sufficiently serious to be grounds for impeachment in most jurisdictions. Because of all the additional procedural safeguards afforded to defendants charged with more serious criminal offenses, defendants must usually consent to any prosecution effort to downgrade a criminal offense to a lower level at which fewer safeguards are offered.
