Criminal Law:

Implications of a Crimes Classification

The category under which a crime is classified makes a considerable difference in both 1) substantive law and 2) procedural criminal law.  Substantive criminal law defines the elements of many crimes in reference to whether they were committed in furtherance of a felony. For example, burglary requires proof that the defendant broke into another person's residence with the intent to commit a felony. If a defendant convinces a jury that he only had the intent to steal a misdemeanor's worth of property after breaking into the victim's home, the jury cannot return a conviction for burglary.
1) The substantive consequences for being convicted of a felony are also more far reaching than the consequences for other types of crimes. One convicted of a felony is disqualified from holding public office in many jurisdictions, may also lose their right to vote, to serve on a jury, and in several states, attorneys convicted of a felony lose their right to practice law.
2) Criminal procedure sets forth different rules that govern courts, defendants, and law enforcement agents, depending on the level of offense charged.  For example, the Fourth Amendment to the U. S Constitution allows police officers to make arrests of suspected felons in public areas without warrants, so long as the arresting officer possesses probable cause that the suspect committed the crime. Officers may make warrantless arrests of suspected misdemeanants, but only if the crime is committed in the officer's presence. Police officers do not have the authority to shoot an alleged misdemeanant while attempting to make an arrest, unless the shots are fired in self-defense. Officers generally have more authority to use deadly force when effectuating the arrest of a felon.
Most criminal courts have limited jurisdiction over the kinds of cases they can hear, that is, a court with authority over only misdemeanors has no power to try a defendant charged with a felony. Defendants may be charged by information, whereas many jurisdictions require that defendants be charged by a grand jury when they are accused of a felony.
Defendants charged with capital felony offenses 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. Defendants charged with infractions or misdemeanors that do not result in incarceration are not entitled to court appointed counsel.
Accused felons must 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.
