Before R OSENBAUM , L UCK , and B RASHER , Circuit Judges.

P ER C URIAM : This is the second appeal in this international kidnapping case. In the first appeal, we found that the district court made twolegal errors. First, “the district court was mistaken when it concluded that it did not have the c hoice to consider” the father’s “noncredible denials as evidence supporting” the mother’s “testimony.” Silva v. Dos Santos , 68 F.4th 1247, 1259 (11th Cir. 2023). And second,the district court erred in “concluding that a single witness’s testimony [was] necessarily insufficient to satisfy the clear

- and

- convincing

- evidence standard.” Id. “Because the district court’s reasoning did not account for these principles, we vacate[d] the district court’s order and remand[ed] for further consideration in light o f [our] opinion.” Id. at 1261. On remand, the district court reviewed and considered the testimony and evidence from the evidentiary hearing. Based on its review, the district court granted the father’s petition for the return of his daughter to Brazil. The mother appeals. She argues that we must vacate the district court’s order because it violated the mandate rule. Ourmandate, the mother contends, required the district court to “announce how” the application of the rule

— that disbelief of a litigant ’s testimony can be substantive evidence against that litigant

— affected its judgmen t . And, the mother asserts, our mandate required the district court “to consider and explain why” the USCA11 Case: 23-12456 Document: 24-1 Date Filed: 10/16/2023 Page: 2 of 423

- 12456 Opinion of the Court 3 mother’s testimony “alone failed to support a finding by clear and

con vincing evidence.” But , the mother argues, the district court’s order didn’t do the things we required it to do because it was “insufficient” and “perfunctory

. ” “We review de novo the district court’s interpretation and application of” our mandate. Cox Enters

. , Inc. v. News

- J. Corp. , 794 F.3d 1259, 1272 (11th Cir. 2015). Under the mandate rule, “whenan appellate court issues a specific mandate it is not subject to interpretation; the district court has an obligation to carry out the order.” Id. at 12 71 (quotation omitted). It must “implement boththe letter and the spirit of the mandate taking into account the appellate court’s opinion and the circumstances it embraces.” Id. (quotation and omissions omitted). Here, the district court carried out b oth the letter and spirit of our mandate. In the conclusion section of our first opinion , we summarized the two legal principles we instructed the district court to consider on remand . First, “when a factfinder does not believe an interested witness ’ s te stimony, it may

—but is not required to

— consider that witness’s discredited testimony as corroborating substantive evidence that the opposite of the testimony is true.” Silva , 68 F.4th at 1261. And second, “when a single witness provides the only evidence on some point, that testimony, without corroboration, can still meet the standard of clear and convincing evidence if the factfinder concludes that it is credible.” Id. Then,

w e vacated the original order and remanded for further consideration of the evidence in light of the se two legal principles. Id. ; see USCA11 Case: 23-12456 Document: 24-1 Date Filed: 10/16/2023 Page: 3 of 44 Opinion of the Court 23

also id. at 1250 (“Accordingly, we vacate the district court’s order and remand for further consideration.”).
Th at’s what the district court did. It “recognize [ d ] ” the two leg al errors it made in its original order. And, with our guidance in mind

— “ heed [ ing ] ” our opinion

— it “again reviewed and considered the testimony and evidence” from the evidentiary hearing, including the father’s incredible testimony and the mother’s testim ony. “Upon such renewed review and consideration,” the district court granted the father’s petition to return his daughter to Brazil. While the order on remand is brief, the district court did what we asked it to do. It recognized the errors that it ma de in the original order, and, guided by our opinion in the first appeal, thedistrict court considered the evidence in light of the two legal principles. We remanded for “further consideration” based on our opinion , s ee id. at 1261 , and the district cour t “considered” the correct legal principles and applied them to the evidence. Because we didn’t require the district court to do more than that, it did not violate the mandate rule by not saying more. And because the district court did not violate the m andate rule, we do not have to consider the mother’s arguments about why we shouldenter judgment on the merits in her favor, or why we should “remand

. . . to a different district court judge.”
AFFIRMED. USCA11 Case: 23-12456 Document: 24-1 Date Filed: 10/16/2023 Page: 4 of 4
