Kiley, Swygert and Kerner, Circuit Judges.
This case presents the issue whether a federal district court has the power and duty to conduct a hearing regarding the constitutional validity of a prior narcotics conviction which a defendant seeks to exclude from the record for the purposes of his sentencing as a second offender as provided for under 21 U.S.C. § 174.
The instant suit commenced with the return of a one-count indictment on November 14, 1967, charging the defendant, Carlos Martinez, with facilitating the transportation of approximately 2000 grams of heroin in violation of 21 U.S.C. § 174. The defendant was arraigned on December 6, 1967, and a plea of guilty was entered to the charges in the indictment. At that time, the Government, pursuant to 26 U.S.C. § 7237(c) (2),*fn1 introduced a certified copy of the defendant's previous conviction of a violation of the United States narcotics laws. This document recited a prior conviction based on the defendant's plea of guilty in 1956 before the United States District Court for the Southern District of Florida and the two-year sentence imposed by the court. Additionally, this document indicated on its face the fact that the defendant had been represented by counsel in the Florida proceeding. As a result of introduction of this prior conviction, the district judge was denied discretion to impose a five-year minimum sentence and the defendant was given the minimum mandatory ten-year sentence without parole.*fn2
The defendant moved to strike from the record the certified copy of his prior conviction on the ground that his plea was involuntarily entered in violation of the fifth amendment. In support of the motion the defendant filed his affidavit and a brief. The defendant also requested leave to obtain a transcript of the proceedings before the Florida district court and other evidence relevant to a determination of the voluntariness of his plea. A full hearing on the voluntariness question was sought. On February 9, 1968, the district court heard oral argument and refused the defendant's request to strike the prior conviction from the record on the ground that the judge did not believe he had the authority or jurisdiction to grant the motion. It is this ruling of the district court which is before us upon appeal.
From the defendant's uncontroverted affidavit and the transcript of the prior Florida proceedings, it appears that on March 16, 1956, the defendant appeared before the Honorable Emett C. Choate, United States District Judge, for the Southern District of Florida for arraignment on a two-count information that charged him with selling, dispensing and distributing a narcotic drug, and with purchasing and possessing a narcotic drug in violation of 26 U.S.C. §§ 4704 and 4704(a). Upon the court's determination that the defendant lacked funds to retain counsel, the court entered an order appointing counsel for him.
The defendant, by affidavit, states that he was not guilty of the Florida charge, although he admits being addicted to the use of narcotics during this period. He further avers that as a Spanish-speaking citizen he required the assistance of an interpreter at the 1956 Florida proceedings. As a result of this language barrier, the defendant spoke with his court-appointed attorney through an interpreter who spoke very poor Spanish. According to the defendant, his lawyer did not explain the law to him or advise him of his right to a jury trial. Initially, his lawyer advised the defendant to plead not guilty, but following a brief conference with some other individual, the lawyer returned and represented to the defendant that if he would plead guilty, he would receive treatment for his narcotic addiction. Although he still maintains his innocence, the defendant asserts that he pleaded guilty solely because he was undergoing withdrawal symptoms and was promised treatment. According to the defendant's affidavit, the trial judge did not question him concerning any promises or representations made to him in exchange for the plea of guilty as to one count of the information. Following his plea of guilty and imposition of the two-year sentence, the defendant was transported to Lexington, Kentucky, for hospitalization and to serve his sentence.
The appellant's argument is grounded on the premise that a constitutionally invalid prior conviction cannot be used to enhance a sentence imposed under 21 U.S.C. § 174. To support this position the appellant relies on the due process clause of the fifth amendment as recently interpreted by the Supreme Court in Burgett v. Texas, 389 U.S. 109, 88 S. Ct. 258, 19 L. Ed. 2d 319 (1967). In that case the defendant was convicted by a jury of assault with intent to commit murder in a state court trial. A Texas habitual offender statute allowed the prosecution to introduce evidence of the defendant's four prior felony convictions. Among these was a certified copy of a Tennessee conviction which on its face raised a presumption that the defendant had been denied his right to counsel, and thus the prior conviction was void in light of Gideon v. Wainwright, 372 U.S. 335, 83 S. Ct. 792, 9 L. Ed. 2d 799 (1963). In reversing his conviction, the Court stated the following principle:
To permit a conviction obtained in violation of Gideon v. Wainwright to be used against a person either to support guilt or enhance punishment for another offense * * * is to erode the principle of that case. Burgett v. Texas, 389 U.S. 109, 115, 88 S. Ct. 258, 19 L. Ed. 2d 319 (1967).
We view the Burgett rationale, although involving a denial in the previous state court conviction of the sixth amendment right to counsel set forth in Gideon, as directly analogous to the instant facts. Here it is contended that the previous conviction was tainted by a denial of the defendant's fifth amendment right to due process as well as his right to the effective assistance of counsel provided by the sixth amendment. In both Burgett and the case before us, a prior conviction was utilized to enhance the defendant's punishment through invocation of an applicable mandatory subsequent offender provision that could not have been used but for the prior conviction. In both Burgett and the instant case, the prior conviction was alleged to have been obtained in vioation of a fundamental federal constitutional right.
The Government's position is that the Burgett rationale is inapplicable to the instant case because the constitutional invalidity discussed in Burgett appeared on the face of the record, whereas, here, no such defect appears. This argument admits the defendant's contention that the district court did have the power to strike from the record a constitutionally invalid prior conviction for purposes of sentencing a second offender. The Government admits that if absence of counsel at the prior proceeding were manifest on the face of the record, the district court could strike the prior proceeding from the present record. We are unable to accept the Government's proffered distinction between invalidity on the face and latent invalidity as a qualification on the district court's power to strike. If the district court has the power to strike invalid prior convictions, it is only fundamental that the same court with its inherent fact finding power and incidental power to conduct hearings can determine which prior convictions are invalid.
In our opinion the Government's contention that the district court lacked the power to strike the defendant's prior conviction from the record and to hold a hearing to determine the constitutional validity thereof must fall in light of Burgett's rationale and the fundamental power of federal courts to establish rules of evidence and hold hearings incident to implementation of exclusionary rules. The application of exclusionary rules through court hearings has been repeatedly recognized and exercised. Weeks v. United States, 232 U.S. 383, 34 S. Ct. 341, 58 L. Ed. 652 (1914) (illegally seized evidence); McNabb v. United States, 318 U.S. 332, 63 S. Ct. 608, 87 L. Ed. 819 (1943) (statements of the accused); Alderman v. United States, 394 U.S. 165, 89 S. Ct. 961, 22 L. Ed. 2d 176 (1969) (illegal electronic eavesdropping). The Government relies on Burton v. United States, 272 F.2d 473 (9th Cir.1959), cert. denied, 362 U.S. 951, 80 S. Ct. 863, 4 L. Ed. 2d 869 (1960) to support its position that federal courts are not empowered to strike prior convictions. We view the Burton case in light of the Supreme Court's subsequent decision in Burgett to be necessarily limited to valid prior convictions. It is our conclusion that the district court has the power to conduct a hearing to ascertain the constitutional validity of a prior conviction which the Government attempts to introduce for the purpose of enhancing punishment.
The Government's alternative argument is that the defendant's affidavit failed to raise detailed facts sufficient to require the district court to hold a hearing to determine the constitutionality of the defendant's prior conviction. The Government relies principally on Machibroda v. United States, 368 U.S. 487, 82 S. Ct. 510, 7 L. Ed. 2d 473 (1962) and Oliver v. United States, 398 F.2d 353 (9th Cir.1968) to support its position that the defendant's allegations were vague and conclusory. Our examination of Machibroda indicates that the defendant here was entitled to a hearing. In both cases the defendant's contention was that his plea had been coerced by a promise. A hearing was sought in each case on the basis of the defendant's affidavit alone. The affidavit here raises facts in sufficient detail to require a hearing to determine whether the defendant's plea was "induced by promises * * * which deprive it of the character of a voluntary act." Machibroda v. United States, 368 U.S. 487, 493, 82 S. Ct. 510, 513, 7 L. Ed. 2d 473 (1962). We find that the specificity requirements of the Oliver case are likewise met by the Martinez affidavit.
The defendant has alleged that at the time he entered his plea of guilty he was under the influence of heroin and was suffering from withdrawal symptoms. On similar facts it has been held that a guilty plea based on a confession obtained while the defendant is suffering from withdrawal symptoms was not voluntary. United States ex rel. Collins v. Maroney, 287 F. Supp. 420 (E.D.Pa.1968). The entry of a plea of guilty while under the influence of narcotics which is alleged in this case is potentially more substantial error, since "entry of a plea of guilty demands even more stringent safeguards than are required for confessions." United States ex rel. Codarre v. ...
