The issue to be decided in this appeal is whether the district court complied with the procedural safeguards mandated by Criminal Rule 11 prior to accepting the three defendants' guilty pleas. We conclude that the plea hearing conducted by the district court, while perhaps somewhat less than ideal, adequately met the requirements of Rule 11. We therefore affirm.

On February 17, 1993, a federal grand jury in Puerto Rico indicted Jose Ramon Cotal-Crespo, Antonio De Jesus-De Jesus and Ivan Rodriguez-Bocachica, in Count I, of conspiring to possess with intent to distribute multi-kilograms of cocaine, in violation of 21 U.S.C. Sec. 846. In addition, the indictment alleged, in Counts II and III, that Cotal-Crespo used a communication facility (a telephone) in facilitating the commission of a drug trafficking offense, in violation of 21 U.S.C. Sec. 843(b). On March 3, 1993, the defendants entered pleas of not guilty.

On June 8, 1993, the date their trial was scheduled to begin, defendants requested a change of their respective pleas to guilty. Defendants did not enter a plea agreement with the government. The district court held a change of plea hearing and subsequently accepted defendants' guilty pleas. Sentencing was scheduled for September 9, 1993.

On August 11, 1993, defendants filed a pro se, joint motion requesting withdrawal of their guilty pleas. The district court appointed each defendant new counsel and the motion was argued on March 4, 1994, 847 F. Supp. 991. The district court denied the joint motion in an Opinion and Order issued the same day. Cotal-Crespo was eventually sentenced to 120 months on Count I and to 48 months on Counts II and III, to be served concurrently. Rodriguez-Bocachica and De Jesus-De Jesus were each sentenced to 120 months on Count I. Pending before this Court is defendants' consolidated appeal of the denial of their motion to withdraw their guilty pleas.

Defendants advance two arguments in support of their contention that they should have been permitted to withdraw their guilty pleas pursuant to Criminal Rule 11. First, they contend that the district court failed to inform them of the nature of the charges against them and determine that they understood those charges. In support of this contention, defendants maintain that they believed that the eight kilograms of cocaine they were caught with could be split amongst them for sentencing purposes and that they were consequently prejudiced by the district court's failure to explain the nature of the conspiracy charge. Second, defendants contend that the district court failed to inform them of the consequences of their guilty pleas. They assert, inter alia, that the district court did not explain to them that by pleading guilty they waived their constitutional rights to a jury trial, to remain silent, and to confront witnesses against them.

A defendant may withdraw a guilty plea prior to sentencing only upon a showing of "fair and just reason" for the request. See United States v. Pellerito, 878 F.2d 1535, 1537 (1st Cir.1989); see also Fed.R.Crim.P. 32(d). There are several factors to consider in determining whether a defendant has met this burden, the most significant of which is whether the plea was knowing, voluntary and intelligent within the meaning of Rule 11. United States v. Allard, 926 F.2d 1237, 1243 (1st Cir.1991). The other factors include: 1) the force and plausibility of the proffered reason; 2) the timing of the request; 3) whether the defendant has asserted his legal innocence; and 4) whether the parties had reached a plea agreement. Pellerito, 878 F.2d at 1537. In this case, defendants focus their argument on the alleged Rule 11 violations--contending that these violations establish that their pleas could not have been knowing, voluntary and intelligent.

By entering a guilty plea, a defendant effectively waives several constitutional rights. For that waiver to be valid, due process requires that the plea amount to a voluntary and "intentional relinquishment or abandonment of a known right or privilege." McCarthy v. United States, 394 U.S. 459, 466, 89 S. Ct. 1166, 1171, 22 L. Ed. 2d 418 (1969) (quoting Johnson v. Zerbst, 304 U.S. 458, 464, 58 S. Ct. 1019, 1023, 82 L. Ed. 1461 (1938)); Allard, 926 F.2d at 1244. Rule 11 was intended to ensure that a defendant who pleads guilty does so with an "understanding of the nature of the charge and the consequences of his plea." McCarthy, 394 U.S. at 467, 89 S.Ct. at 1171.

(c) Advice to Defendant. Before accepting a plea of guilty or nolo contendere, the court must address the defendant personally in open court and inform the defendant of, and determine that the defendant understands, the following:

(1) the nature of the charge to which the plea is offered, the mandatory minimum penalty provided by law, if any, and the maximum possible penalty provided by law, including the effect of any special parole or supervised release term, the fact that the court is required to consider any applicable sentencing guidelines but may depart from those guidelines under some circumstances ... and

* * * * * *

(3) that the defendant has the right to plead not guilty or to persist in that plea if it has already been made, the right to be tried by a jury and at that trial the right to the assistance of counsel, the right to confront and cross-examine adverse witnesses, and the right against compelled self-incrimination; and

(4) that if a plea of guilty or nolo contendere is accepted by the court there will not be a further trial of any kind so that by pleading guilty or nolo contendere the defendant waives the right to trial; and

(5) if the court intends to question the defendant under oath, on the record, and in the presence of counsel about the offense to which the defendant has pleaded, that the defendant's answers may later be used against him in a prosecution for perjury or false statement.

(d) Insuring that the Plea is Voluntary. The court shall not accept a plea of guilty or nolo contendere without first, by addressing the defendant personally in open court, determining that the plea is voluntary and not the result of force or threats or of promises apart from a plea agreement.

Fed.R.Crim.P. 11(c), (d) (emphasis added).

We have distinguished between "technical" violations of Rule 11 and violations of the rule's "core concerns," and held that a violation that "implicates one of the rule's 'core concerns' mandates that the plea be set aside." United States v. Medina-Silverio, 30 F.3d 1, 3 (1st Cir.1994) (citing Allard, 926 F.2d at 1244). Rule 11's core concerns are: 1) absence of coercion; 2) understanding of the charges; and 3) knowledge of the consequences of the guilty plea. Allard, 926 F.2d at 1244-45.1

In determining whether there has been a core violation, we review the totality of the circumstances surrounding the Rule 11 hearing, rather than apply a "talismanic test." See id. at 1245 (citing United States v. Dayton, 604 F.2d 931, 939 (5th Cir.1979), cert. denied 445 U.S. 904, 100 S. Ct. 1080, 63 L. Ed. 2d 320 (1980)). What is critical is the substance of what was communicated by the trial court, and what should reasonably have been understood by the defendant, rather than the form of the communication. See Medina-Silverio, 30 F.3d at 3 (emphasizing that there is no "formula of 'magic words' in meeting the requirements of Rule 11"). At a minimum, Rule 11 requires that the trial court address the defendant personally in open court to ascertain that his plea is "voluntary and intelligent." See id. at 2-3 (citing Fed.R.Crim.P. 11(c)).

In the absence of a total failure to address one of Rule 11's core concerns, the question is whether irregularities in the plea-taking proceeding affected the defendant's "substantial rights." Fed.R.Crim.P. 11(h). Other than for errors of law, we will overturn the trial judge's decision not to allow the withdrawal of a guilty plea only for "demonstrable abuse of discretion," and the trial court's subsidiary findings of fact in connection with the plea-withdrawal motion are reviewed only for clear error. Allard, 926 F.2d at 1245 (citing Pellerito, 878 F.2d at 1538).

Defendants contend that the trial court failed to determine that they understood the nature of the charges against them, as required by Rule 11(c)(1). See United States v. Ruiz-Del Valle, 8 F.3d 98, 102 (1st Cir.1993). Defendants maintain that they believed that the eight kilograms of cocaine could be "somehow split among the three for sentencing," and, therefore, assert that they were prejudiced by the trial court's failure to explain that each of them would be held responsible for the cocaine found in their collective possession, regardless of any stated intention to later split the drugs.

There are two central difficulties with this argument. First of all, the amount of drugs for which each defendant is held responsible is an issue relevant to sentencing, not to a particular defendant's guilt. See United States v. Musa, 946 F.2d 1297, 1305 (7th Cir.1991); United States v. Young, 927 F.2d 1060, 1065 (8th Cir.), cert. denied, 502 U.S. 943, 112 S. Ct. 384, 116 L. Ed. 2d 334 (1991).2 Secondly, the trial court personally addressed each defendant and discussed with him the maximum and minimum penalties provided by law for his offense. After fully explaining the guideline ranges, the court informed each defendant that the minimum sentence on Count I is 120 months. When asked if they understood this, each defendant answered in the affirmative. In addition, the trial court personally addressed each defendant and asked him to "tell his story" with respect to the charges against him. In telling their respective stories, none of the defendants gave the slightest indication that they disputed the amount of drugs involved or their role in the transaction vis-a-vis the total amount of drugs.

Defendants also argue that they must be allowed to withdraw their guilty pleas because the trial court did not read or explain the charges to them. Our review of the plea hearing transcript reveals that the trial court did not read the charges nor did it explain the law of conspiracy.

It is not necessary that the explanation of the charges come directly from the court, however, if it can be discerned from a review of the proceeding that the defendant nevertheless understood the charges. See Allard, 926 F.2d at 1246 (citing Dayton, 604 F.2d at 943). See also United States v. Musa, 946 F.2d 1297, 1305 (7th Cir.1991); United States v. Darling, 766 F.2d 1095, 1099 (7th Cir.) (citing cases), cert. denied, 474 U.S. 1024, 106 S. Ct. 579, 88 L. Ed. 2d 561 (1985); United States v. Cusenza, 749 F.2d 473, 476 (7th Cir.1984); United States v. Gray, 611 F.2d 194, 200 (7th Cir.), cert. denied, 446 U.S. 911, 100 S. Ct. 1840, 64 L. Ed. 2d 264 (1980); United States v. Coronado, 554 F.2d 166, 173 (5th Cir.), cert. denied, 434 U.S. 870, 98 S. Ct. 214, 54 L. Ed. 2d 149 (1977). Thus, where the prosecutor's statement or the defendant's description of the facts sets forth all elements of the offense and the conduct of the defendant that constitutes the offense, "the defendant's admission that the allegations are true is sufficient evidence that he understands the charge." Darling, 766 F.2d at 1099. See Allard, 926 F.2d at 1246.

In this case, each defendant stated at the plea hearing that he went, together with the other two defendants, to buy the drugs. In addition, Cotal-Crespo admitted to making phone calls with respect to the drug transaction. Thus, each defendant's admission of the events underlying the transaction accurately described the elements of a violation of 21 U.S.C. Sec. 846--an agreement to buy a large amount of drugs3--and Cotal-Crespo's admission described the elements of a violation of 21 U.S.C. Sec. 843(b). Moreover, each of the defendants agreed with the prosecutor's detailed summary of the facts the government would prove at trial, which also included a description of all the elements of both charges.

The manner in which the charge is explained and the method for determining the defendant's understanding of the charge will vary from case to case depending upon the complexity of the charges, the capacity of the defendant, and the attendant circumstances. Allard, 926 F.2d at 1245. See also Darling, 766 F.2d at 1098. "[W]hile the subtleties of conspiracy law may be the bane of criminal law students, the basic principle is easily understood: a group of people agreeing to do something illegal." United States v. Carter, 815 F.2d 827, 829 (1st Cir.1987). We find nothing in the record to indicate that the defendants did not understand the drug conspiracy charge.4 Rather, the plea hearing indicates that the defendants knew exactly what they were charged with and voluntarily made the decision to plead guilty.

The defendants also contend that the trial judge failed to inform them of the consequences of their guilty pleas. Specifically, they claim that the court failed to determine that they understood and waived their rights to remain silent, to a jury trial, and to confront witnesses against them. In addition, they contend that the court did not explain the possibility of departure from the guidelines or counsel the defendants about the possibility of a later prosecution for perjury based upon their statements at the Rule 11 hearing. We necessarily turn to an examination of the plea colloquy.

The trial court began by asking each defendant whether he had read and understood the petition questions, and whether he had consulted with his attorney regarding those questions and his answers. Each defendant answered in the affirmative. The court then asked the standard questions to determine whether the defendants were competent to plead and whether they were satisfied with their attorneys. The court asked each defendant whether he remembered reading and answering questions about his right to a jury trial and whether he understood that if he pleads guilty he will be found guilty without a trial. The defendants responded in the affirmative to all these questions.

Next, the court asked each of the defendants to give their "story" with respect to the charges against them, which each defendant did. Then the government gave a detailed summary of the evidence it would prove at trial and each defendant indicated his agreement with the government's recitation of the pertinent evidence. The court then informed each defendant of the maximum and minimum penalties provided by law for the charged offenses and received their assurances that they understood their potential sentences. Finally, the court asked each defendant whether, knowing the possible penalties, including the mandatory minimum of 120 months, they wanted to plead guilty. Each defendant answered in the affirmative. The court did not specifically ask the defendants whether they knew and understood their rights to remain silent and to confront witnesses against them, nor did it mention the possibility of departure or a perjury charge.

It is abundantly clear from the transcript of the hearing that the defendants understood the nature of the charges against them, understood their right to a jury trial, understood their potential sentences, agreed with the prosecutor's recitation of what the government would prove at trial, and, most importantly, acknowledged, with no perceptible hesitation, their guilt based on those allegations. Moreover, there was no need to discuss departure from the guidelines because all the parties agreed that there was a statutory minimum of 120 months. The narrow question for decision, therefore, is whether the failure of the trial court to specifically mention the right to remain silent, the right to confront witnesses, and the possibility of a perjury charge, standing alone, mandates that defendants be permitted to withdraw their guilty pleas. We conclude, based on the totality of the circumstances, that it does not.

The district court explained, and determined on the record that the defendants understood many of the "consequences" of their guilty pleas. This is, therefore, not a case of a "total failure" to address one of Rule 11's core concerns. See Allard, 926 F.2d at 1244-45 (citing McCarthy, 394 U.S. at 471-72, 89 S.Ct. at 1173-74.5 The question, therefore, is whether the district court's failure to inform the defendants of all of the consequences of their pleas, as delineated by Rule 11, "affected defendants' substantial rights." See Fed.R.Crim.P. 11(h). For the reasons explained below, we conclude that Rule 11's core concern that defendants understand the consequences of their plea was adequately addressed in this case and that the defendants' substantial rights were not violated. We therefore hold that the district court's failure to explicitly address all of Rule 11's requirements was harmless error.

The record of the plea hearing is replete with evidence that the defendants understood the charges against them, faced up to them, and chose voluntarily to plead guilty. It is clear also that the defendants understood that they had the right to persist in their innocence and go to trial, and that they had read and understood the petition questions, which explained that they had the right to remain silent and to confront witnesses against them. Moreover, the trial court meticulously explained, and ensured on the record that the defendants understood, the maximum and minimum statutory penalties and their sentencing guideline ranges. Each defendant stated on the record that he understood that his minimum sentence would be 120 months.

Finally, we are mindful of the traditional factors relevant to the review of a change of plea request.6 First, defendants waited two months before deciding that they did not understand the consequences of their guilty pleas. Second, defendants have not asserted their legal innocence. Third, defendants have not argued, much less attempted to show, that the knowledge that they had the right to remain silent and to confront the witnesses against them at trial would have materially affected their decisions to plead guilty.

Defendants argue that our decision in Medina-Silverio requires reversal. In that case, however, we held only that:

Where a district court neither conducts a direct personal interrogation, nor advises the defendant of his rights, all substantially as required under Rule 11, there can be no sufficient basis for finding that the guilty plea was voluntary, intelligent or otherwise valid.

Medina-Silverio, 30 F.3d at 3. Thus, a trial court's reliance solely on answers provided by a defendant in a written document is insufficient for purposes of Rule 11. In this case, in addition to answers provided in a written document, however, the court personally and meticulously addressed each of the defendants with respect to the alleged facts underlying the charges against him, his right to a jury trial and the maximum and minimum sentences.

In 1968, the Supreme Court explained that Rule 11 was designed, at least in part, to produce a complete record to enable reviewing courts to determine, based on a cold transcript, whether a plea was voluntary. The Court thus commented that:

[T]he more meticulously the Rule is adhered to, the more it tends to discourage, or at least to enable more expeditious disposition of, the numerous and often frivolous post-conviction attacks on the constitutional validity of guilty pleas.

McCarthy, 394 U.S. at 465, 89 S.Ct. at 1170. Although we conclude that the Rule 11 hearing in this case was adequate, we are nevertheless compelled to remind district courts that, for the sake of judicial economy and fundamental fairness, the best way to ensure that Rule 11 is complied with is to explicitly comply with Rule 11.

The judgment of the district court is affirmed.
