Everyone charged with a misdemeanor or felony crime in the state of Pennsylvania is entitled to a Preliminary Hearing. (The only exception is Pennsylvania's Indicting Grand Jury). At the Preliminary Hearing, the government must prove that there is a prima facie case that (1) an offense has been committed and (2) the defendant has committed it. If the government cannot meet this burden then the case must be dismissed. If the government does meet its burden, then the charges are "held over" and sent up to the Court of Common Pleas.
