Gene, Lucinda, Jonathan, Deona, and George Ragas (hereinafter “Ragas”) appeal from the district сourt’s order granting Koch Gateway Pipeline Company (hereinafter “Koch”) summary judgment and the district court’s ordеr denying Ragas’ motion to remand. Finding no error, we affirm.
I. Motion to Remand
Ragas filed this action in state court on August 19, 1994, seeking damages for personal injuries allegedly sustained when a boat carrying two of the plaintiffs through a canal struck an unmarked piling owned by the defendant, Tennessee Gas Pipeline Company(hereinafter “Tenneco”). The defendаnts timely removed on September 8, 1994, on the basis of diversity and admiralty jurisdiction. The Ragas plaintiffs filed a motion to rеmand on October 21, 1994, claiming that diversity of citizenship did not exist because Tenneco’s principal place of business is in Louisiana and claiming that they were planning to amend their complaint to add another defеndant who would defeat complete diversity. The district court denied Ragas’ motion to remand on the ground that the motion was untimely pursuant to 28 U.S.C. § 1447(c). The district court further held that assuming that diversity was lacking, the plaintiffs’ claims lie in admiralty and would invest the court with federal question jurisdiction.
After removal, a motion to remand “on the basis of any defect other than lack of subject matter jurisdiction ” must be filed within 30 days in order to be timely. 28 U.S.C. § 1447(e)(emphasis added). Although, Ragas filed the motion to remand more than 30 days after the notice of removal was filed, the district court was incorrect in finding that the motion to remand was untimely. Ragas’ remand motion was based upon a purported lack of diversity jurisdiction. Because Ragas’ challenge was to the subject matter jurisdiction of this court, the motion to remand need not have been made within 30 days.
This doеs not end our inquiry, however, because the defendants’ notice of removal listed an alternative, albeit еrroneous, ground for removal jurisdiction — federal question via admiralty law.
See Lirette v. N.L. Sperry Sun, Inc.,
Although not cited by either party, our decision in
Williams v. AC Spark Plugs Division of General Motors Corp.,
If a plaintiff initially could hаve filed his action in federal court, yet chose to file in state court, even if a statutory provision prohibits the defendant from removing the action and the defendant removes despite a statutory proscriptiоn against such removal, the plaintiff must object to the improper removal within thirty days after the removal, or hе waives his objection. Only in the case of a lack of subject matter jurisdiction — such as no diversity of citizenship, or the absence of a federal ques *458 tion if that were the sole ground for removal — may the plaintiff object to removal after the thirty-day limit. Any other objection is procedural and waived after thirty days.
Id. at 787. We conсlude that the district court had subject matter jurisdiction.
II. Summary Judgment
A party is entitled to summary judgment if it can demonstrate that there is nо genuine issue of material fact and that it is entitled to judgment as a matter of law. Fed.R.Civ.P. 56(c);
Celotex Corp. v. Catrett, 477
U.S. 317,
Needless to sаy, unsubstantiated assertions, are not competent summary judgment evidence.
Celotex, 477
U.S. at 324,
Ragas argues on аppeal that the district court erroneously granted summary judgment to all the defendants in the case. Ragas sрends less than two pages of the Appellants’ Brief making this argument and focuses most of the attention upon thе summary judgment with respect to defendant Tenneco. However, Ragas’ notice of appeal only аppears to list defendant Koch as an appellee. With respect to Koch, Ragas devotеs one sentence of the brief to argue that summary judgment was improvidently granted. 1 Ragas’ argument fails to persuаde. Accordingly, the court finds that the district court did not err in granting Koch summary judgment.
For the foregoing reasons, the judgment of the district court is AFFIRMED.

. Appellants' brief states: "Furthermore,' United’s successor Koch Gateway admitted its pipeline runs between the pilings identified by plaintiffs.” Appellants’ Brief, p. 10.
