Judges.

PER CURIAM:
              Case: 19-11497     Date Filed: 07/08/2020    Page: 2 of 15



      In this consolidated appeal, Cesar Octavio Armenta Lopez (“Lopez”)

appeals the revocation of his supervised release as well as his conviction for

conspiracy to possess with intent to distribute cocaine on a vessel subject to the

jurisdiction of the United States. Lopez says the district court did not have subject

matter jurisdiction over his conspiracy charge because the record did not establish

that the vessel he was on at the time of his arrest was subject to the jurisdiction of

the United States. He also argues that the district court abused its discretion by

revoking his supervised release without first allowing him to address the court, and

by erroneously concluding that he admitted to the supervised release violations.

After careful consideration, we vacate Lopez’s criminal conviction and remand for

further proceedings consistent with this opinion. However, we affirm the

revocation of Lopez’s supervised release.

                                           I.

      Lopez and six codefendants were charged by a superseding indictment with

violations of the Maritime Drug Law Enforcement Act (“MDLEA”) in the

Southern District of Florida. Lopez was charged with conspiracy to possess with

intent to distribute five kilograms or more of cocaine while on board a vessel

subject to the jurisdiction of the United States, in violation of 46 U.S.C. § 70506(b)

(Count 1), and possession with intent to distribute five kilograms or more of

              Case: 19-11497     Date Filed: 07/08/2020   Page: 3 of 15



cocaine while on board a vessel subject to the jurisdiction of the United States, in

violation of 46 U.S.C. § 70503(a)(1) and 18 U.S.C. § 2 (Count 2).

      Lopez pled guilty to Count 1 pursuant to a plea agreement. The factual

proffer given with his plea agreement states that Lopez agreed to serve as a

crewmember on a motorboat transporting cocaine from Colombia to Mexico. On

June 28, 2018, Lopez was on a 30-foot-long open motor boat in the Pacific Ocean,

along with six other men. The factual proffer states that the “boat had no hull

numbers, registration in any country, or flag” and was “travelling in international

waters.” On board the boat were bales containing over five kilos of cocaine.

Shortly after midnight on June 28, a United States Coast Guard vessel approached

the boat and ordered that it stop to be searched. The boat drove away evasively

and at a high rate of speed, while crewmen threw the bales of cocaine overboard.

Early in the morning, the motorboat came to a stop and all the men aboard,

including Lopez, were taken into custody.

      At the time of this arrest, Lopez was serving a five-year term of supervised

release for an unrelated MDLEA conviction in the Southern District of California.

In August 2018, the probation office for that district notified the court that Lopez

committed three violations of the terms of his supervised release. Violations 1 and

2 alleged that Lopez committed “another federal, state or local crime,” and tracked

the language of Counts 1 and 2 of the superseding indictment for each. Violation 3



                                          3
              Case: 19-11497     Date Filed: 07/08/2020   Page: 4 of 15



alleged that Lopez failed to report to probation within 24 hours of reentering the

United States “[o]n or before June 28, 2018.” Several months later, jurisdiction

over the alleged supervised release violations was transferred to the Southern

District of Florida.

      At Lopez’s change-of-plea hearing in his criminal matter, the district court

confirmed Lopez’s understanding of Count 1 of the superseding indictment. In

explaining to Lopez the elements of this offense, the court stated that the

government would have to prove beyond a reasonable doubt that Lopez entered

into a conspiracy, and that “the object of this agreement was for each of the

conspirators to possess a controlled substance, which in this case was more than

five kilograms of cocaine, while onboard a vessel subject to the jurisdiction of the

United States.” Lopez confirmed that he understood this. The court also asked

Lopez whether the facts contained in the factual proffer were true, which Lopez

confirmed. Apart from accepting the government’s factual proffer, the district

court made no factual findings concerning Lopez’s offense.

      In a single proceeding, the district court sentenced Lopez for his MDLEA

conspiracy conviction and held a revocation hearing as to his supervised release

violation. The court began the proceedings by addressing Lopez’s sentence for his

MDLEA conspiracy conviction. The parties agreed that Lopez’s applicable

Sentencing Guideline range for his conspiracy conviction was between 210- and



                                          4
              Case: 19-11497     Date Filed: 07/08/2020    Page: 5 of 15



262-months imprisonment. However, Lopez’s counsel stated Lopez “timely

indicate[d] that he wanted to resolve his case by pleading guilty both to the

underlying substantive case and the supervised release case.” Therefore, the

parties jointly recommended a below-Guideline total sentence of 180-months

imprisonment, “which would include the underlying substantive case along with

the supervised release violation.” The parties’ recommendation consisted of “168

months on the criminal case and an additional 12 months to run consecutive” for

the supervised release violation. For his MDLEA conspiracy conviction in Count

1, the district court sentenced Lopez to 168-months imprisonment, along with a

five-year term of supervised release.

      The district court then turned to the revocation of Lopez’s supervised

release, and asked defense counsel to state Lopez’s position as to the alleged

violations. With respect to Violations 1 and 2, which tracked Counts 1 and 2 of

Lopez’s superseding indictment, defense counsel responded that “[Lopez] is going

to admit the violations and plead guilty.” With respect to the third violation, which

alleged that Lopez failed to report within 24 hours of returning to the United

States, defense counsel said, “I don’t know that [Lopez] was in a position to report

but for purposes of this hearing we can resolve it.” On that basis, the district court

found that “Mr. Armenta Lopez has admitted his guilt to the three violations of

supervised release as set forth in the petition.” Before announcing its sentence, the

               Case: 19-11497     Date Filed: 07/08/2020     Page: 6 of 15



district court offered Lopez an opportunity to address the court. Lopez responded

by asking the court “for mercy.” The district court then sentenced Lopez to 12-

months imprisonment for his supervised release violations, to be served

consecutively to his 168-month sentence for MDLEA conspiracy.

                                            II.

      The district court’s subject matter jurisdiction is a question of law that we

review de novo, even when subject matter jurisdiction is challenged for the first

time on appeal. United States v. Iguaran, 

, 1336 (11th Cir. 2016)

(per curiam). A district court’s revocation of supervised release is generally

reviewed for an abuse of discretion. United States v. Frazier, 

, 112

(11th Cir. 1994). However, where an objection is raised for the first time on

appeal, we review for plain error. United States v. Gresham, 

, 1265

(11th Cir. 2003). To prove plain error, a defendant must show: (1) error, (2) that is

plain, (3) that affects his substantial rights; and (4) that seriously affected the

fairness of the judicial proceedings.

argues that his conviction under Count 1 must be vacated and

reversed because the district court failed to make a preliminary finding of subject

matter jurisdiction, as required under the MDLEA, 46 U.S.C. § 70504. He also

argues that the district court’s failure to explain the MDLEA’s jurisdictional



                                             6
              Case: 19-11497      Date Filed: 07/08/2020    Page: 7 of 15



requirement during his plea colloquy rendered his guilty plea unknowing and

involuntary. Lopez correctly observes that the district court failed to make the

required finding as to its jurisdiction, so we remand for limited factfinding on that

issue. And since the court’s jurisdiction is a threshold issue, we do not reach

Lopez’s argument concerning the validity of his plea at this time.

      Under the MDLEA, it is a crime to “knowingly or intentionally . . .

manufacture or distribute, or possess with intent to manufacture or distribute, a

controlled substance” while on board “a vessel subject to the jurisdiction of the

United States,” and to conspire to do the same. 46 U.S.C. §§ 70503(a)(1), (e)(1),

and 70506(b). In 1996, Congress amended the MDLEA to clarify that

“[j]urisdiction of the United States with respect to a vessel subject to this chapter is

not an element of an offense.”

United States v. Campbell, 

, 805 (11th Cir. 2014). Rather, “[j]urisdictional issues arising under this chapter

are preliminary questions of law to be determined solely by the trial judge.” 46

U.S.C. § 70504(a). This Court has “interpreted the ‘on board a vessel subject to

the jurisdiction of the United States’ portion of the MDLEA as a congressionally

imposed limit on courts’ subject matter jurisdiction, akin to the amount-in-

controversy requirement contained in 28 U.S.C. § 1332.” 

. Therefore, in order “for a district court to have adjudicatory authority over a

charge that a defendant conspired to violate the substantive crime defined in the



                                           7
                Case: 19-11497      Date Filed: 07/08/2020       Page: 8 of 15



MDLEA, the Government must preliminarily show that the conspiracy’s vessel

was, when apprehended, subject to the jurisdiction of the United States.”

(quotation marks omitted).

       The MDLEA’s definition of a “vessel subject to the jurisdiction of the

United States” includes, among other things, “a vessel without nationality.” 46

U.S.C. § 70502(c)(1)(A). 1 A vessel without nationality includes (a) “a vessel

aboard which the master or individual in charge makes a claim of registry that is

denied by the nation whose registry is claimed”; (b) “a vessel aboard which the

master or individual in charge fails, on request of an officer of the United States

authorized to enforce applicable provisions of United States law, to make a claim

of nationality or registry for that vessel”; and (c) “a vessel aboard which the master

or individual in charge makes a claim of registry and for which the claimed nation

of registry does not affirmatively and unequivocally assert that the vessel is of its

nationality.”

       As the government concedes, there is nothing in Lopez’s factual proffer,

presentence investigation report, or plea hearing that establishes he was on board a

vessel without nationality at the time of his arrest. See Br. of Appellee at 10. As a




1
 The MDLEA recognizes six categories of “vessel[s] subject to the jurisdiction of the United
States.” See 46 U.S.C. § 70502(c)(1). However, the parties agree that only one of the six
categories applies here: “a vessel without nationality.” See

Br. of
Appellant at 12–14; Br. of Appellee at 9.

result, the record is insufficient to establish the district court’s subject matter

jurisdiction over the MDLEA offense in Count 1. It is the government’s burden to

show that a vessel is subject to the jurisdiction of the United States. See United

States v. Tinoco, 

, 1114 (11th Cir. 2002). Thus, the government’s

failure to establish jurisdiction in the district court would ordinarily be grounds to

dismiss the indictment. See, e.g., United States v. Guerro, 789 F. App’x 742, 750–

51 (11th Cir. 2019) (unpublished). However, where the defendant’s “failure to

challenge the district court’s jurisdiction is at least partially responsible for the lack

of a developed record, we have said that the proper course of action is to remand

the case to the district court for factual findings as to jurisdiction.” 

(alteration adopted) (quotation marks omitted).

      Lopez challenges the district court’s jurisdiction over his MDLEA offense

for the first time here on appeal. We therefore remand this matter to the district

court to determine whether subject matter jurisdiction exists. On limited remand,

the government should be given an opportunity to submit evidence supporting its

assertion that Lopez’s vessel was subject to the jurisdiction of the United States,

and Lopez should be afforded an opportunity to present evidence that it was not.

government carries its burden of establishing that Lopez was on board a

vessel subject to the jurisdiction of the United States when he was arrested, the

court should reinstate Lopez’s conviction. 2
 

court finds that the

government has not proven jurisdiction, it should enter a judgment dismissing

Count 1 for lack of jurisdiction.
 Id.

       Lopez also 
says his plea agreement was invalid because the district court

(a) failed to determine its jurisdiction prior to accepting Lopez’s plea agreement;

and (b) erroneously advised Lopez at his plea colloquy that the MDLEA’s

jurisdiction requirement was an element of his offense. Because the court’s subject

matter jurisdiction over Lopez’s indictment is a threshold matter, we do not address

Lopez’s argument concerning the validity of his plea agreement at this time. See

Steel Co. v. Citizens for a Better Env’t, 
523 U.S. 83
, 94–95, 
118 S. Ct. 1003
, 1012

(1998) (“The requirement that jurisdiction be established as a threshold matter

springs from the nature and limits of the judicial power of the United States and is

inflexible and without exception.” (alteration adopted) (quotation marks omitted)).

                                               IV.

       Lopez argues that his due process rights were violated when the district

court failed to give him an opportunity to address the court personally before

adjudicating him guilty of the supervised release violations. He also says the

  The government argues that, on remand, it need only prove facts establishing the district court’s
jurisdiction by a preponderance of the evidence. This Court has yet to decide “whether the
government must establish the jurisdictional requirement beyond a reasonable doubt or by a
preponderance of the evidence.”

n.25. We decline to now opine on
the proper standard of proof. Instead, we allow the district court to make that determination, if
necessary, in the first instance.

district court erred in finding that he admitted to the supervised release violations.

Finally, Lopez says there was no factual basis for the district court to accept his

guilty plea to Violation 3. None of these arguments warrant reversal under plain

error review.3

       Defendants in revocation proceedings are entitled to certain minimal due

process requirements, which are incorporated in Federal Rule of Criminal

Procedure 32.1. 
Frazier, 26 F.3d at 114
. Relevant here, principles of due process

require that a defendant facing a revocation of his supervised release has an

“opportunity to be heard in person and to present witnesses and documentary

evidence.” Morrissey v. Brewer, 
408 U.S. 471
, 489, 
92 S. Ct. 2593
, 2604 (1972);

see also Fed. R. Crim. P. 32.1(b)(2)(E) (providing that the defendant is “entitled to

. . . an opportunity to make a statement and present any information in

mitigation”). In the context of a criminal guilty plea, Federal Rule of Criminal

Procedure 11 requires a district court to “address the defendant personally in open

court and inform the defendant of, and determine that the defendant understands[,]

the nature of the charge to which the plea is offered and the potential consequences

of that plea.” United States v. Lewis, 
115 F.3d 1531
, 1535 (11th Cir. 1997) (per

curiam) (alteration adopted) (quotation marks omitted). However, this Court has

 Because Lopez raises these arguments for the first time on appeal, we review them for plain
error. See 
Gresham, 325 F.3d at 1265
.

held that Rule 11 does not apply in the context of revocation proceedings. See

United States v. Johns, 
625 F.2d 1175
, 1176 (5th Cir. Unit B 1980).4

       Lopez says he was not given an “opportunity to be heard in person” because

the district court did not invite him to personally address the court prior to

accepting his guilty plea. He argues that, under the Supreme Court’s decision in

Morrissey, this is a violation of his due process rights. However, Lopez has not

demonstrated that the district court plainly erred. Although Morrissey held that

defendants have a due process right “to be heard in person” before the revocation

of supervised release, nothing in that opinion suggests that an “opportunity to be

heard” means an opportunity to personally address the court. 
See 408 U.S. at 489
,

92 S. Ct. at 2604. Indeed, in Morrissey, the Court expressly declined to impose

any rigid procedures that a court must follow before revoking a term of supervised

release.
 Id. at 488, 
92 S. Ct. at 2604 (declining to “write a code of procedure” for

revocation hearings). And while Rule 11 does require the district court to address

the defendant personally, 
Lewis, 115 F.3d at 1535
, Rule 11 does not apply in

revocation proceedings, 
Johns, 625 F.2d at 1176
. Because no precedent of the

Supreme Court or this Court “directly resolv[es]” Lopez’s challenge in his favor,

the district court did not commit plain error. See United States v. Lejarde-Rada,

 In Bonner v. City of Prichard, 
661 F.2d 1206 
(11th Cir. 1981) (en banc), this Court adopted as

September 30, 1981.

319 F.3d 1288
, 1291 (11th Cir. 2003) (per curiam) (holding that plain error does

not exist when “the explicit language of a statute or rule does not specifically

resolve an issue” and “there is no precedent from the Supreme Court or this Court

directly resolving it”).

      Lopez also argues that the district court plainly erred in “finding that [he]

had admitted all three violations.” Br. of Appellant at 19. Lopez appears to argue

the district court’s failure to elicit an express guilty plea from Lopez himself—as

opposed to one communicated through counsel—constituted a due process

violation. In United States v. Moriarty, 
429 F.3d 1012 
(11th Cir. 2005) (per

curiam), this Court held in the context of a criminal guilty plea that a district

court’s failure to elicit an “express declaration of [the defendant’s] guilty plea was

not plain error” because nothing in the record “indicat[ed] that [the defendant]

meant to plead other than guilty.”
 Id. at 1020. 
Here, Lopez plainly intended to

plead guilty. During his revocation proceeding, defense counsel stated that Lopez

“timely indicate[d] that he wanted to resolve his case by pleading guilty both to the

underlying substantive case and the supervised release case.” (emphasis added).

With respect to supervised release Violations 1 and 2, defense counsel stated that

Lopez was “going to admit the violations and plead guilty.” And as to Violation 3,

counsel stated that, “for purposes of [the revocation] hearing we can resolve it.”

Nothing in the record suggests that Lopez did not intend to plead guilty. Indeed,



                                           13
                Case: 19-11497        Date Filed: 07/08/2020        Page: 14 of 15



when given an opportunity to address the court personally, Lopez asked only for

the court’s mercy. On this basis, the district court reasonably concluded that Lopez

intended to plead guilty to all three supervised release violations. See
 id. at 1019–
20.

       With respect to Violation 3, Lopez argues the district court plainly erred in

accepting his guilty plea because the alleged violation was factually impossible.

He points out that Violation 3 alleges he failed to report to the probation officer

within 24 hours of his reentry into the United States “[o]n or before June 28,

2018.” However, the factual proffer signed by the parties in Lopez’s criminal

matter states that he “was travelling in international waters” on June 28, 2018.

Thus, according to Lopez, there was no factual basis for the court to accept his

guilty plea. While there is some facial merit to Lopez’s challenge, we conclude

Lopez invited any error on the part of the district court when he agreed to plead

guilty to Violation 3. See United States v. Love, 
449 F.3d 1154
, 1157 (11th Cir.

2006) (per curiam) (holding that defendant induced error at sentencing hearing by

conceding that the court could impose a term of supervised release). As a result,

we are precluded from reviewing this argument on appeal.5 United States v.


5
 In his reply brief, Lopez also says there was no basis to find him guilty of Violations 1 and 2,
which alleged that he committed “another federal, state or local crime,” namely Counts 1 and 2
of the superseding indictment. He argues that, because the district court never established
subject matter jurisdiction over Counts 1 and 2, those offenses did not constitute a “federal, state,
or local crime,” and thus could not serve as a basis for his supervised release revocation.
Because Lopez raises this issue for the first time in his reply brief, we do not consider it. See
