PER CURIAM:
              Case: 17-12818     Date Filed: 06/01/2018    Page: 2 of 13


      Teofilo Ruiz-Murillo appeals his conviction for one count of conspiracy to

distribute and possess with intent to distribute one kilogram or more of cocaine on

board a vessel subject to the jurisdiction of the United States, in violation of

46 U.S.C. §§ 70503(a) and 70506(b) under the Maritime Drug Law Enforcement

Act (the “MDLEA”). Without holding a hearing, the district court denied Ruiz-

Murillo’s motion to dismiss the indictment, finding that there was subject matter

jurisdiction under the MDLEA and that venue was proper in the Southern District

of Alabama. The district court did not err in denying the motion to dismiss; thus,

we affirm.

                                I. BACKGROUND

      The United States Coast Guard spotted a flagless go-fast vessel operated by

three persons at night in international waters west of Panama. Traveling on a

course consistent with drug smuggling and without navigation lights, the vessel

made erratic course and speed changes as the Coast Guard approached. The Coast

Guard observed crewmembers aboard the vessel jettisoning objects into the sea,

including a kilo-sized package that later tested positive for cocaine.

      Coast Guard officers boarded the vessel. Crewmember Ericirilo Murillo-

Ruiz stated that he was the vessel’s master and that it was a Colombian flagged

vessel. All three crewmembers claimed Colombian nationality. During




                                           2
              Case: 17-12818    Date Filed: 06/01/2018    Page: 3 of 13


questioning by the Coast Guard, one of the crew admitted that there were illegal

narcotics aboard the boat.

      Because Murillo-Ruiz claimed that the vessel was Colombian, the Coast

Guard promptly requested that the Republic of Colombia verify the crewmembers’

claim of the vessel’s nationality. Colombia responded that it could neither confirm

nor deny the vessel’s registry in Colombia. The Coast Guard officials then

continued to search the vessel and surrounding area. The Coast Guard located the

package that the crewmembers had thrown off the vessel, which tested

presumptively positive for cocaine. The Coast Guard then transported the

crewmembers to Guantanamo Bay, Cuba. From there, they were taken to Mobile,

Alabama.

      Ruiz-Murillo and the other two crewmembers were charged by criminal

complaint in the Southern District of Alabama for manufacturing, distributing, or

possessing with intent to distribute a controlled substance on board a vessel subject

to the jurisdiction of the United States. At a preliminary hearing before a

magistrate judge, Ruiz-Murillo argued that the MDLEA was inapplicable, meaning

the court lacked subject matter jurisdiction, because the vessel was not stateless

and because the stop occurred in territorial waters, not the high seas. To prove

jurisdiction, the government introduced a U.S. Department of State certification

(the “Certification”). The Certification recounted that U.S. authorities contacted


                                          3
                Case: 17-12818   Date Filed: 06/01/2018    Page: 4 of 13


the Colombian government to confirm the boat’s claimed nationality, and

Colombian authorities responded that they could neither confirm nor deny the

boat’s registry or nationality. The Certification also stated that the Coast Guard

detected the vessel in international waters at the approximate location of 06-29N,

078-16W, “seaward of the territorial sea of any State.” Further, a Department of

Homeland Security agent testified at the preliminary hearing that the stop occurred

in international waters. The magistrate judge concluded that there was federal

jurisdiction.

      A grand jury then indicted Ruiz-Murillo and the other crew members for

manufacturing, distributing, or possessing with intent to distribute a controlled

substance on board a vessel subject to the jurisdiction of the United States. Ruiz-

Murillo moved to dismiss the indictment arguing that (1) the United States lacked

subject matter jurisdiction because the vessel was not stateless and the stop did not

occur in international waters; (2) the MDLEA was unconstitutional because it did

not require proof of a nexus between the United States and Ruiz-Murillo; and (3)

the Southern District of Alabama was not the appropriate venue.

      The United States opposed the motion to dismiss. First, the government

argued that there was jurisdiction because it had conclusively proven through the

Certification that the vessel was stateless and that the stop occurred in international

waters. Second, the government explained that Ruiz-Murillo’s argument that the


                                           4
              Case: 17-12818    Date Filed: 06/01/2018    Page: 5 of 13


MDLEA was unconstitutional was foreclosed by precedent. Third, the government

argued that venue existed in the Southern District of Alabama because Ruiz-

Murillo entered the United States in Mobile, which is located in the Southern

District of Alabama.

      The district court denied, without a hearing, Ruiz-Murillo’s motion to

dismiss. Regarding the motion to dismiss, the district court found that there was

jurisdiction because the vessel was stateless. Ruiz-Murillo never refuted or

contradicted the government’s evidence establishing jurisdiction—that is, that the

vessel’s master claimed Colombian registry and that Colombia could neither

confirm nor deny the master’s claim. Moreover, the court found that that the

vessel was in international waters at all relevant times, another finding Ruiz-

Murillo offered no evidence to refute. The district court also concluded that the

MDLEA as applied was constitutional and that venue was proper in the Southern

District of Alabama.

      Ruiz-Murillo pled guilty, reserving the right in his written plea agreement to

appeal any issues raised in his pretrial motions, including jurisdiction and venue.

This is his appeal.

                          II. STANDARD OF REVIEW

      This Court reviews questions of constitutional law and statutory subject

matter jurisdiction de novo. United States v. Whatley, 719 F.3d 1206, 1213 (11th


                                          5
              Case: 17-12818     Date Filed: 06/01/2018    Page: 6 of 13


Cir. 2013); United States v. McPhee, 336 F.3d 1269, 1271 (11th Cir. 2003). We

review a district court’s denial of an evidentiary hearing for an abuse of discretion.

United States v. Barsoum, 763 F.3d 1321, 1328 (11th Cir. 2014). We review de

novo a district court’s denial of a motion to dismiss an indictment for improper

venue. United States v. Muench, 153 F.3d 1298, 1300 (11th Cir. 1998).

      An appellant abandons an argument by failing to raise the issue plainly and

prominently on appeal. United States v. Jernigan, 341 F.3d 1273, 1283 n.8 (11th

Cir. 2003). Additionally, we disregard as harmless any error that does not affect a

defendant’s substantial rights. Fed. R. Crim. P. 52(a).

                                 III. DISCUSSION

      On appeal, Ruiz-Murillo argues that the district court erred in determining

that (1) it had subject matter jurisdiction; (2) the MDLEA was constitutional; and

(3) venue was proper. We disagree, for the reasons expressed below.


A.    The District Court Did Not Err in Concluding That It Had Subject
      Matter Jurisdiction.

      The Constitution empowers Congress “[t]o define and punish Piracies and

Felonies committed on the high Seas, and Offences against the Law of Nations.”

U.S. Const. art. I, § 8, cl. 10. Pursuant to this power, Congress enacted the

MDLEA to prohibit any person from “knowingly or intentionally . . . possess[ing]

with intent to manufacture or distribute, a controlled substance [on board] . . . a


                                           6
              Case: 17-12818     Date Filed: 06/01/2018    Page: 7 of 13


vessel subject to the jurisdiction of the United States.” 46 U.S.C. § 70503(a), (e).

The statute specifies that a vessel without nationality is subject to the jurisdiction

of the United States. Id. § 70502(c)(1)(A). A vessel without nationality, in turn,

includes “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.” Id. § 70502(d)(1)(C).

The claimed nation’s response “is proved conclusively by certification of the

Secretary of State or the Secretary’s designee.” Id. § 70502(d)(2) (emphasis

added). Ruiz-Murillo argues that the district court erred in concluding that it had

jurisdiction under the MDLEA because of disputes about whether the vessel was

stateless and whether the stop occurred in international waters.

      Ruiz-Murillo first argues that the district court improperly concluded that the

vessel was stateless. Establishing jurisdiction over a vessel, he argues, requires

“some amalgam of proof.” Here, the vessel’s master claimed Colombian registry.

Colombia responded, however, that it could neither confirm nor deny the vessel’s

Colombian registry. The Certification signed by a designee of the Secretary of

State reflects these facts. Ruiz-Murillo relies on United States v. Hernandez, 864

F.3d 1292 (11th Cir. 2017), to argue that the Certification requires a “deliberative

process” when challenged. But Hernandez does not support this proposition and

instead reinforces that “‘the response of a foreign nation to a claim of


                                           7
                Case: 17-12818       Date Filed: 06/01/2018       Page: 8 of 13


registry . . . is proved conclusively by certification of the Secretary of State or the

Secretary’s designee.’” Hernandez, 864 F.3d at 1299 (quoting 46 U.S.C.

§ 70502(d)(2)).

       Ruiz-Murillo next argues that the district court should have granted him an

evidentiary hearing on the jurisdictional issue because “the boat’s location and the

chronology of events was a mystery.” He argues that he was entitled to a hearing

to show that the vessel was not stopped in international waters. He cites United

States v. Bellaizac-Hurtado, 700 F.3d 1245 (11th Cir. 2012), for the proposition

that Congress cannot enforce United States drug trafficking laws in the territorial

waters of another nation. It is true that in Bellaizac-Hurtado we held that Congress

lacked authority under the Constitution’s Offences Clause to proscribe drug

trafficking conduct that occurred in another country’s territorial waters. Id. at

1258. But here the district court found that the vessel operated “in international

waters at all relevant times” because all listed sets of coordinates—taken from the

Certification and other Coast Guard documents—“define locations that are far

more than 12 miles beyond the Coast of Colombia and therefore lie in international

waters, as a matter of law.” 1 In determining the vessel’s location, the district court

relied on the Certification, Coast Guard incident notes, the Coast Guard “Action
       1
          Ruiz-Murillo also argues that a search in territorial waters would violate the United
Nations Convention against Illicit Traffic in Narcotic Drugs and Psychotropic Substances. We
reject this argument because (1) the undisputed record shows that the vessel was in international
waters at all times and (2) the MDLEA explicitly precludes a defendant from arguing failure to
comply with international law as a defense. See 46 U.S.C. § 70505.
                                                8

Request” form, and a Homeland Security agent’s testimony. Ruiz-Murillo does

not dispute the accuracy of the coordinates and has come forward with no evidence

to refute that these coordinates are in international waters. We have held that the

law does not compel a district court to hold an evidentiary hearing where a

defendant’s motion fails to allege facts that if proven would require the grant of

relief. See United States v. Sneed, 732 F.2d 886, 888 (11th Cir. 1984). Thus, the

district court did not err in refusing to hold an evidentiary hearing.

       In a closely related argument, Ruiz-Murillo contends that his due process

rights were violated because the magistrate judge improperly heard case-

dispositive issues. Federal Rule of Criminal Procedure 59 limits the issues that a

magistrate judge may decide to nondispositive matters and certain dispositive

matters upon referral from the district court judge. Fed. R. Crim. P. 59. The

Federal Magistrates Act, however, specifically authorizes district court judges to

designate a magistrate judge to hear and determine various pretrial matters. 28

U.S.C. § 636(b)(1)(A). The Supreme Court has confirmed the constitutionality of

this practice. See United States v. Raddatz, 447 U.S. 667, 683 (1980) (holding that

a trial judge’s adoption of a magistrate judge’s findings related to a suppression

hearing does not violate due process “so long as the ultimate decision is made by

the district court”).




                                           9
             Case: 17-12818     Date Filed: 06/01/2018    Page: 10 of 13


      Even assuming that the magistrate judge erred by ruling on the jurisdictional

issue, any error was harmless. Ruiz-Murillo filed a formal motion to dismiss based

on lack of subject matter jurisdiction that the district court decided. Although the

district court relied on the undisputed evidence introduced at the hearing, the

district court adopted no portion of the magistrate judge’s factual findings.

Accordingly, any error resulting from the magistrate’s jurisdictional determination

was harmless.

B.    The District Court Did Not Err in Determining that the MDLEA Was
      Constitutional.

      Ruiz-Murillo argues that his conviction should be vacated because the

MDLEA is unconstitutional for not requiring a nexus between a defendant and the

United States. Under the prior panel precedent rule, this Court is bound to follow a

prior decision unless and until it is overruled by this Court sitting en banc or by the

Supreme Court. United States v. Vega-Castillo, 540 F.3d 1235, 1236 (11th Cir.

2008). We have previously held that “the conduct proscribed by the [MDLEA]

need not have a nexus to the United States because universal and protective

principles support its extraterritorial reach.” United States v. Campbell, 743 F.3d

802, 810 (11th Cir. 2014). Subsequent cases reaffirm our holding that the MDLEA

does not require a nexus to the United States. See United States v. Wilchcombe,

838 F.3d 1179, 1186 (11th Cir. 2016), cert. denied, 137 S. Ct. 2265 (2017); United



                                          10
             Case: 17-12818     Date Filed: 06/01/2018   Page: 11 of 13


States v. Cruickshank, 837 F.3d 1182, 1187–88 (11th Cir. 2016), cert. denied, 137

S. Ct. 1435 (2017).

      Ruiz-Murillo invokes Bellaizac-Hurtado in urging this Court to reconsider

the constitutionality of the MDLEA. In Bellaizac-Hurtado, we held that Article I

of the Constitution curtails the MDLEA’s reach for conduct occurring in territorial

seas. See 700 F.3d at 1249–58. In that case, the Coast Guard pursued the

defendants in Panamanian waters. Id. at 1247. The United States relied on the

Offences Clause to justify its authority to prohibit the defendants’ drug trafficking

in territorial seas. Id. at 1248–49. Although we held in Bellaizac-Hurtado that the

enforcement of drug trafficking laws in territorial waters falls outside Congress’s

power under the Offences Clause, this case stems from Congress’s authority under

the Felonies Clause, which permits the government to prosecute crimes occurring

on the high seas—that is, outside of territorial waters. See id. at 1257 (“[W]e have

always upheld extraterritorial convictions under our drug trafficking laws as an

exercise of power under the Felonies Clause.”). Here, the United States presented

undisputed evidence that Ruiz-Murillo committed the instant offense in

international waters, making Bellaizac-Hurtado inapplicable. We must reject

Ruiz-Murillo’s argument because our prior precedent forecloses it.




                                          11
               Case: 17-12818      Date Filed: 06/01/2018       Page: 12 of 13


C.     The District Court Did Not Err in Finding Venue Proper in the
       Southern District of Alabama.

       The MDLEA specifies that venue is proper in the district court of the United

States for the district in which a defendant enters the United States. 46 U.S.C.

§ 70504(b)(1) (2017).2 Ruiz-Murillo argues that the district court erred in denying

his motion to dismiss for improper venue because the United States failed to

present evidence sufficient to establish venue in Mobile, Alabama. The argument

fails because an indictment is not subject to a pretrial motion to dismiss on the

ground of insufficient venue. See United States v. Snipes, 611 F.3d 855, 866 (11th

Cir. 2010) (holding that venue determination in a pretrial evidentiary hearing

would be improper because a jury must decide whether venue exists).

       Ruiz-Murillo points out that the government incorrectly asserted that hearing

testimony established his transport to Guantanamo Bay and then to the Southern

District of Alabama. However, the district court did not rely upon the

government’s misrepresentation that prior testimony had established venue;

instead, it relied upon the government’s proffer in the indictment that venue was

proper in the Southern District of Alabama. If a grand jury returns a facially valid

indictment containing a proper statement of venue, pretrial determination of venue


       2
         During this appeal’s pendency, Congress amended 46 U.S.C. § 70504(b) to expand
venue to all districts if the offense was begun or committed on the high seas. Because Ruiz-
Murillo’s venue objection fails even under the previous, narrower venue standard, we need not
examine whether the amendments apply retroactively.

on the merits is improper because the issue is reserved for a jury’s determination.

See id. at 866–67 (“To permit preliminary trials on essential facts, post-indictment,

would ‘run counter to the whole history of the grand jury institution, . . . [and]

would result in interminable delay but add nothing to the assurance of a fair trial.’”

(quoting Costello v. United States, 350 U.S. 359, 363–64 (1956))).3

                                     IV. CONCLUSION

       For the foregoing reasons, we affirm the judgment of the district court.

AFFIRMED.




       3
          Ruiz-Murillo also filed a separate motion to suppress, contending that the Coast Guard
lacked reasonable suspicion to board the vessel. In support of this motion, he again raised the
argument that the MDLEA did not apply because the stop occurred in Colombian waters, not
international waters. The district court found that the Coast Guard had reasonable suspicion to
search the vessel, noting that the crew jettisoned items from the vessel, which appeared to be
weighted down, was on a course consistent with drug smuggling, was moving erratically, and
was operating at night without navigation lights. Ruiz-Murillo’s motion to suppress also neither
refutes nor contradicts the government’s evidence that the district court used in determining that
the search was reasonable. Accordingly, the district court did not err in refusing to conduct an
evidentiary hearing on the suppression motion.
