VICINAY CADENAS, S.A.,

            Defendant - Appellee



                Appeal from the United States District Court
                     for the Southern District of Texas


                            Opinion on Rehearing
Before JOLLY, JONES, and BENAVIDES, Circuit Judges.
PER CURIAM:
      The panel hereby clarifies its previous opinion, Petrobras Am., Inc. v.
Vicinay Cadenas, 815 F.3d 211 (5th Cir. 2016), as follows.
      The holding announced in Part I of the panel’s opinion, concluding that
Vicinay did not waive its choice of law argument under the Outer Continental
Shelf Lands Act (“OCSLA”), necessarily depended upon the unique statutory
scheme created by OCSLA.         Through OCSLA, Congress legislated the
trichotomy of federal law, state law, and residual maritime law for disputes
arising on the Outer Continental Shelf. See Rodrigue v. Aetna Cas. & Sur. Co.,
                                  No. 14-20589
395 U.S. 352, 355, 89 S. Ct. 1835 (1969) (“the purpose of the [OCSLA] was to
define a body of law applicable to the seabed, the subsoil and the fixed
structures such as those in question here on the Outer Continental Shelf.”).
And Section 1333(a) of OCSLA “supersede[s] the normal choice of law rules
that the forum would apply.” In re DEEPWATER HORIZON, 745 F.3d 157,
166 (5th Cir. 2014) (citing Gulf Offshore Co. v. Mobil Oil Corp., 453 U.S. 473,
480–81, 101 S. Ct. 2870 (1981)). Consequently, our holding does not address
waiver of a choice of law argument outside of the OCSLA context and does not
disturb authorities holding that, in other contexts, a choice of law argument
may be waived.
       In re HECI Exploration Corp., 862 F.2d 513, 520 (5th Cir. 1988), the
case cited by the petition for rehearing en banc for the proposition that the
panel’s opinion creates an intra-circuit conflict, is emblematic of such non-
OCSLA authority. HECI is distinguishable for a multitude of reasons: because
it is based on ERISA law, involved a preemption defense, and is by its own
terms confined to its facts.     Indeed, the HECI panel emphasized that it
“announce[d] no general principle regarding the proper course of conduct for
an appellate court confronted with a situation in which the parties fail to argue
the applicable federal law in a federally preempted area such as ERISA.” Id.
at 526.   Furthermore, the HECI holding was “necessarily colored by [the
panel’s] position” as a “second-level appellate court” reviewing a bankruptcy
court decision, id., which is, of course, not the case here.
      Finally, this appeal arises in admiralty in an interlocutory posture
because the choice of law argument was raised in a motion for leave to amend
a complaint, and a claim technically remains pending before the district court.
Consequently, the panel opinion does not opine on different scenarios, such as
where a party raises a choice of law argument under OCSLA for the first time
after trial and judgment.
