The plaintiff-appellee in this action, the Division of Archives of the State of Florida, originally filed this case in state court to determine ownership of a sunken vessel and to enjoin the defendant from excavating the vessel. The defendant-appellant filed a motion for removal to federal court and the appellee responded with a motion to remand for lack of federal jurisdiction. The district court granted the motion to remand, from which order the appellant appeals.

The appellee's main argument on appeal is that under 28 U.S.C. Sec. 1447(d) this court is without jurisdiction to hear the appeal. Section 1447(d) provides:

An order remanding a case to the state court from which it was removed is not reviewable on appeal or otherwise, except that an order remanding a case to the state court from which it was removed pursuant to Sec. 1443 of this title shall be reviewable by appeal or otherwise.1

The Supreme Court in Thermtron Products, Inc. v. Hermansdorfer, 423 U.S. 336, 96 S. Ct. 584, 46 L. Ed. 2d 542 (1976) held that Sec. 1447(d) bars review of a remand order only if the district court's basis for remand was Sec. 1447(c), which requires a remand if "it appears that the case was removed improvidently and without jurisdiction ...." 28 U.S.C. Sec. 1447(c). See also Gravitt v. Southwestern Bell Telephone Company, 430 U.S. 723, 97 S. Ct. 1439, 52 L. Ed. 2d 1 (1977). If the lower court acted on the basis of Sec. 1447(c), review is barred "whether or not that order might be deemed erroneous by an appellate court." Thermtron, 96 S. Ct. at 593. This circuit has further held that review of a remand order is available under Thermtron only in a case where "a district judge stated openly that he was relying on a non-1447(c) ground for remand." In re Merrimack Mutual Fire Insurance Company, 587 F.2d 642 (5th Cir.1978).2

Here, the district court judge did not expressly state that he was remanding because of Sec. 1447(c); nor, however, did he "state[ ] openly" that he was remanding on non-1447(c) grounds. On this basis alone, Merrimack apparently would bar our review of the remand order. We further note that the district court's opinion indicated that it ordered a remand because it believed removal jurisdiction was lacking due to the "saving to suitors" clause of 28 U.S.C. Sec. 1333 and the Eleventh Amendment, both of which are jurisdictional in nature. See Wright & Miller, Federal Practice & Procedure Sec. 3674 (discussion of effect of "saving to suitors" clause on removal jurisdiction); Edelman v. Jordan, 415 U.S. 651, 94 S. Ct. 1347, 1363, 39 L. Ed. 2d 662 (1974) (Eleventh Amendment "partakes of the nature of a jurisdictional bar"). The district court's grounds for remand thus appear to have been within section 1447(c)'s purview.

Because we are barred by 28 U.S.C. Sec. 1447(d) from reviewing the district court's order, the appeal is DISMISSED.
