Terms Used In South Carolina Code 17-27-20

  • Common law: The legal system that originated in England and is now in use in the United States. It is based on judicial decisions rather than legislative action.
  • Conviction: A judgement of guilt against a criminal defendant.
  • Evidence: Information presented in testimony or in documents that is used to persuade the fact finder (judge or jury) to decide the case for one side or the other.
  • Jurisdiction: (1) The legal authority of a court to hear and decide a case. Concurrent jurisdiction exists when two courts have simultaneous responsibility for the same case. (2) The geographic area over which the court has authority to decide cases.
  • Probation: A sentencing alternative to imprisonment in which the court releases convicted defendants under supervision as long as certain conditions are observed.
  • Trial: A hearing that takes place when the defendant pleads "not guilty" and witnesses are required to come to court to give evidence.
  • Writ: A formal written command, issued from the court, requiring the performance of a specific act.

(2) That the court was without jurisdiction to impose sentence;

(3) That the sentence exceeds the maximum authorized by law;

(4) That there exists evidence of material facts, not previously presented and heard, that requires vacation of the conviction or sentence in the interest of justice;

(5) That his sentence has expired, his probation, parole or conditional release unlawfully revoked, or he is otherwise unlawfully held in custody or other restraint; or

(6) That the conviction or sentence is otherwise subject to collateral attack upon any ground of alleged error heretofore available under any common law, statutory or other writ, motion, petition, proceeding or remedy; may institute, without paying a filing fee, a proceeding under this chapter to secure relief. Provided, however, that this section shall not be construed to permit collateral attack on the ground that the evidence was insufficient to support a conviction.

(B) This remedy is not a substitute for nor does it affect any remedy incident to the proceedings in the trial court, or of direct review of the sentence or conviction. Except as otherwise provided in this chapter, it comprehends and takes the place of all other common law, statutory or other remedies heretofore available for challenging the validity of the conviction or sentence. It shall be used exclusively in place of them.
