addition to the right to be represented by counsel. The Sixth Amendment also allows a defendant to know the nature of the accusation against them. All of the Amendments to the United States Constitution are guaranteed to the criminal accused against the states via the Fourteenth Amendment. Thus, a criminal defense lawyer must understand each of these rights. Initial work on any criminal case involves review of the charges and the claimed facts, and analysis of constitutional violations, the prima facie burden of the prosecution, defenses, and affirmative defenses; as well as potential sentence and sentencing issues. Early stages of a criminal case may involve a grand jury or preliminary hearing to determine if there exists probable cause for the case to continue. A violation of the Fourth or Fifth Amendment, or other illegally obtained evidence could result in evidence being inadmissible at trial. Accordingly, a criminal defense lawyer often spends a considerable amount of time reviewing all documentation to determine if the case can be won on constitutional grounds due to illegal conduct by the government. If there are no constitutional violations, much of the work of a criminal defense attorney then turns to trial preparation. Any proposed settlement agreement must be compared to the best judgment about the outcome after trial. A criminal defense lawyer will usually discuss potential plea bargains with the prosecuting attorney, as an alternative to exercising the defendant's trial right and other rights. Plea agreements, when made, can be characterized as either charge agreements (often involving a less serious charge), sentencing agreements (involving a lesser sentence), or both.

A felony typically refers to criminal activity that is punishable by more than one year in the prison system. Many states have "wobblers", which refers to criminal activity that is charged as a felony, but has a possibility of being reduced to a misdemeanor. In matters involving a wobbler, many times a reputable lawyer can either have the felony reduced to a misdemeanor or in the alternative have the felony appear to be a misdemeanor so that the felony can be reduced to a misdemeanor at a later date, which may be good strategy since the typical felony cannot be expunged.
