Arraignment is a formal reading of a criminal charging document in the presence of the defendant, to inform them of the charges against them. In response to arraignment, the accused is expected to enter a plea. Acceptable pleas vary among jurisdictions, but they generally include "guilty", "not guilty", and the peremptory pleas (or pleas in bar) setting out reasons why a trial cannot proceed. Pleas of "nolo contendere" (no contest) and the "Alford plea" are allowed in some circumstances.
