62 STAT.] 80TH CONG., 2D SESS. -CH. 646-JUNE 25, 1948 is granted, any such proceeding shall be as valid as if no habeas corpus proceedings or appeal were pending. § 2252. Notice Prior to the hearing of a habeas corpus proceeding in behalf of a person in custody of State officers or by virtue of State laws notice shall be served on the attorney general or other appropriate officer of such State as the justice or judge at the time of issuing the writ shall direct. § 2253. Appeal In a habeas corpus proceeding before a circuit or district judge, the final order shall be subject to review, on appeal, by the court of appeals for the circuit where the proceeding is had. There shall be no right of appeal from such order in a proceeding to test the validity of a warrant of removal issued pursuant to section 3041 of Title 18 or the detention pending removal proceedings. Ante , p. 815. An appeal may not be taken to the court of appeals from the final order in a habeas corpus proceeding where the detention complained of arises out of process issued by a State court, unless the justice or judge who rendered the order or a circuit justice or judge issues a certificate of probable cause. § 2254. State custody; remedies in State courts An application for a writ of habeas corpus in behalf of a person in custody pursuant to the judgment of a State court shall not be granted unless it appears that the applicant has exhausted the remedies avail- able in the courts of the State, or that there is either an absence of available State corrective process or the existence of circumstances rendering such process ineffective to protect the rights of the prisoner. An applicant shall not be deemed to have exhausted the remedies available in the courts of the State, within the meaning of this section, if he has the right under the law of the State to raise, by any available procedure, the question presented. § 2255. Federal custody; remedies on motion attacking sentence A prisoner in custody under sentence of a court of the United States claiming the right to be released upon the ground that the sentence was imposed in violation of the Constitution or laws of the United States, or that the court was without jurisdiction to impose such sentence, or that the sentence was in excess of the maximum authorized by law, or is otherwise subject to collateral attack, may move the court which imposed the sentence to vacate, set aside or correct the sentence. A motion for such relief may be made at any time. Unless the motion and the 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 United States attorney, 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 the judgment was rendered without jurisdiction, or that the sen- tence imposed was not authorized by law or otherwise open to collateral attack, or that there has been such a denial or infringement of the constitutional rights of the prisoner as to render the judgment vul- nerable to collateral attack, the court shall vacate and set the judgment aside and shall discharge the prisoner or resentence him or grant a new trial or correct the sentence as may appear appropriate. A court may entertain and determine such motion without requiring the production of the prisoner at the hearing. The sentencing court shall not be required to entertain a second or successive motion for similar relief on behalf of the same prisoner. An appeal may be taken to the court of appeals from the order 967
