Francisco Aonso Portillo-Cano (“Portil-lo-Cano” or “defendant”) appeals his guilty plea entered before the district court on the ground that his plea did not conform to the requirements of Rule 11(c) of the Federal Rules of Criminal Procedure. The government asserts that defendant is barred from appealing his sentence because his plea agreement included a waiver of his right to appeal. We hold that we may hear defendant’s appeal in order to determine whether his guilty plea failed to comply with the requirements of Rule 11 because the trial judge did not explain the nature of the charges. We also hold that the plea colloquy at issue did not conform to Rule 11. We have jurisdiction under 28 U.S.C. § 1291 (1994) and we vacate and remand for further proceedings.
I. BACKGROUND
In June 1996, Portillo-Cano was indicted by a grand jury on four counts: Count 1 that he conspired to possess with intent to distribute marijuana, in violation of 21 U.S.C. § 841(a)(1) (1994); Count 2 that he possessed with intent to distribute, and aided, abetted ... or induced ... others to possess with intent to distribute marijuana, in violation of 21 U.S.C. § 841(a)(1) and 18 U.S.C. § 2 (1994); and, Counts 3 and 4, that he used and carried a firearm during and in relation to a drug trafficking crime, in violation of 18 U.S.C. § 924(c) (1994).
In 1995, Portillo-Cano negotiated with a confidential informant (“Cl”) who worked for the U.S. Customs Service. On March 28, 1995, Portillo-Cano gave the Cl a two-ounce sample of marijuana. One week later, Portillo-Cano told the Cl that a large quantity of marijuana was available right away. Portillo-Cano brought the Cl to a residence in Tucson, Arizona where the Cl observed a large quantity of marijuana at the premises. Two men were *1249 guarding the marijuana, one of whom was holding a handgun. A federal search of the residence led to the seizure of 1,160 pounds of marijuana and two firearms.
Pursuant to a Rule 11(e)(1)(C) plea agreement, Portillo-Cano entered a change of plea and pled guilty to Counts 1 and 4 of the indictment on May 28, 1997. Upon entering into an enforceable Rule 11(e)(1)(C) agreement, Portillo-Cano would have waived his right to appeal a sentence called for by. the- agreement. 1 The plea agreement included a provision that Portillo-Cano understood he was giving up his right to appeal the sentence. Portillo-Cano also was to forfeit all right and title to the two firearms. The district court sentenced defendant on March 31, 1998 to 60 months for Count 1, and 11 months for Count 4, to run consecutively. 2
Defendant appealed his conviction and sentence to this court on April 8, 1998. Portillo-Cano claims that in the plea allo-cution of May 28, 1997 the district court judge failed to comply with the requirement of Fed.R.Crim.P. 11(c)(1) that the judge explain, in open court, the nature of the charges brought against the defendant.
II. STANDARD OF REVIEW
We review the validity of a defendant’s waiver of the right to appeal
de novo. United States v. Buchanan,
III. DEFENDANT’S RIGHT TO APPEAL
The government’s only argument on appeal is that Portillo-Cano waived his right to appeal his sentence in his plea agreement. A defendant has a statutory right to appeal his criminal sentence.
See
18 U.S.C. § 3742(a)(1). This right, however, may be waived if the defendant knowingly and voluntarily agrees to the waiver.
United States v. Navarro-Botello,
We recognize that a defendant who has waived the right to appeal may still appeal a criminal sentence under certain circumstances.
See United States v. Schuman,
The cases cited by the Government in support of its argument that the right to appeal was waived validly do not involve situations where the defendant challenged compliance with the Rule 11(c) procedure. In
Schuman,
the court dismissed the appeal on the grounds that the waiver in the plea agreement was expressly stated, and that statements by the district court judge
*1250
that the defendant may still have had some rights to appeal did not give rise to a contrary result because the prosecution objected to this advisement by the court.
Schuman,
As stated by the Seventh Circuit, waivers of appeal must “stand or fall with the agreement of which they are a part.”
United States v. Wenger,
Portillo-Cano is challenging the soundness of his plea allocution under Rule 11, which goes to the heart of whether his guilty plea, including the waiver of appeal, is enforceable. Thus, we must determine whether the plea was valid in order to determine if appeal is permitted.
Our holding in
United States v. Vences,
IV. COMPLIANCE WITH RULE 11(C)(1)
Rule 11(c)(1) of the Federal Rules of Criminal Procedure requires that before accepting a plea of guilty, 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 [and the mandatory minimum penalty and maximum possible penalty].” The purpose of Rule 11 is to “ensure that guilty pleas are knowing and voluntary.”
United States v. Longoria,
In reviewing the compliance of a plea with Rule 11(c), we review only the record of the plea proceeding.
United States v. Jaramillo-Suarez,
As stated in
Smith,
failure to explain the nature of the charge “requires the vacation of a plea of guilty.”
In
Smith
the Government argued that other events at the plea hearing showed that the defendant understood the nature of the charges brought against him, and that the district court had complied with all of the remaining requirements of Rule 11(c).
Id.
The prosecutor in
Smith
established the factual basis for the plea, and the defendant admitted all of those facts. We held that “[w]hile these recitations may satisfy other requirements of Rule 11(c), they do not convey to Smith the nature of the charges against him.... [A]n admission of the facts does not speak to the nature of the charge.”
Id.
at 597. We held that a guilty plea cannot be truly voluntary unless the defendant “possesses an understanding of the law in relation to the facts.”
Id.
(quoting
McCarthy v. United States,
A statement by the defendant and his attorney that they discussed the nature of the charge is also insufficient to satisfy Rule 11(c), because “vague references to discussion of ‘the charges’ and ‘the nature of the charges’ does not provide a complete record showing compliance with Rule 11(c).”
Smith,
Smith
also establishes that the failure to identify the nature of the charges is not harmless error pursuant to Rule 11(h). The omission to identify and explain the crime is “fundamental.”
Smith,
The trial judge in this case did identify the two crimes: conspiracy and use of a firearm during a drug trafficking crime. The judge did not, however, discuss the elements of these crimes in order to demonstrate on the record that the defendant understood the nature of the charges.
See Kamer,
y. CONCLUSION
Because Portillo-Cano’s plea allocution did not include a description of the nature of the charges, including an application of the law to the facts, we find that this plea did not conform to the requirements of Fed.R.Crim.P. 11(c)(1) and that defendant’s right to appeal was not waived. Accordingly, we VACATE the conviction and REMAND for further proceedings consistent with this opinion.
VACATED and REMANDED
Notes
. Pursuant to 18 U.S.C. § 3742(c)(1) (1994) the defendant waives his right to challenge on appeal a sentence imposed pursuant to a plea agreement that "includes a specific sentence under rule 11(e)(1)(C)."
. The district court appears unintentionally to have reversed the sentences for Counts 1 and 4. Count 4 is the count under which the statute requires that a consecutive 60-month sentence be imposed. See 18 U.S.C. § 924(c).
. In
Bruce,
we found that a statement that defendant was pleading guilty to "conspiracy to manufacture methamphetamine” was a "brief, vague explanation [that] in no way
*1251
satisfied the requirements of Rule 11(c)(1).”
Bruce,
. The prosecutor, instead of the judge, may explain the nature of the charges,
Smith,
. In
Smith
we recognized that under an earlier version of Rule 11(c), it was sufficient for the judge to ascertain that the defendant and his attorney had discussed the nature of the charges, because the pre-1974 version of the rule did not require that the trial judge inform the defendant in open court of the nature of the charge.
See Smith
.Prior to the 1975 amendments to Rule 11, any noncompliance with the rule was reversible error.
