"(c) Unless the motion and files and records of the case conclusively show that the prisoner is entitled to no relief, the court shall cause notice thereof to be served upon the prosecuting authority, grant a prompt hearing thereon, determine the issues, and make findings of fact and conclusions of law with respect thereto. If the court finds that (1) the judgment was rendered without jurisdiction, (2) the sentence imposed was not authorized by law or is otherwise open to collateral attack, (3) there has been such a denial or infringement of the constitutional rights of the prisoner as to render the judgment vulnerable to collateral attack, the court shall vacate and set the judgment aside and shall discharge the prisoner, resentence him, grant a new trial, or correct the sentence, as may appear appropriate. "(d) A court may entertain and determine the motion without requiring the production of the prisoner at the hearing. "(e) The court shall not be required to entertain a second or successive motion for similar relief on behalf of the same prisoner. "(f) An appeal may be taken to the District of Columbia Court of Appeals from the order entered on the motion as from a final judgment on application for a writ of habeas corpus.
