This case requires us to determine whether the trial court abused its discretion in allowing the addition of a party that it determined would destroy its jurisdiction and then remanding the case back to state court. Reaching the most crucial conclusion first, we hold that by remand to state court, this case lies irretrievably in state court, despite, as the basis for remand, the trial court’s mistaken belief that it no longer had jurisdiction. The trial court brought its remand order within the absolute immunity from review of 28 U.S.C. § 1447(c) by expressly referring to a lack of jurisdiction as one of the bases of its decision to remand.
Through appeal under 28 U.S.C. § 1291, and a petition for a writ of mandamus, CSX Transportation, Inc. (CSX) and Marler Bennett seek review of both parts of the district court’s order which (i) allowed the amendment adding the Louisiana Department of Transportation and Development (DOTD), and (ii) remanded the case to state court. As for the propriety of allowing the amendment, we hold that this part of the *1025 order did not terminate federal jurisdiction and was therefore an interlocutory, nonap-pealable order. With regard to the trial court’s decision to remand, although the trial court did not mention § 1447(c) by name, the court did cite the destruction of its jurisdiction as one of its grounds for remand. With the order resting on the trial court’s belief that it lacked jurisdiction, the case is irretrievably in state court.
An Unwanted Addition
Near New Orleans, on November 17, 1987, a train owned and operated by CSX with Bennett, the engineer, at the controls struck a tractor/trailer rig driven by David Tillman. There was immediate, complete, thorough diversity jurisdiction from the outset. Tillman, a Mississippi resident, brought suit in Louisiana state court against CSX, a Florida resident, and Bennett, an Alabama resident. CSX and Bennett then properly removed the case to the Eastern District of Louisiana on the basis of diversity.
Soon after removal, Tillman filed for a continuance of the original trial date. The trial court relented, pushing the trial date back to January 22, 1990, with a cut-off date for amendments to pleadings of June 9, 1989. Four months after this deadline for amendments had passed, Tillman moved to file an amended complaint to add the DOTD as a defendant. In addition, Tillman included a motion to remand to state court. The trial court denied this first attempt to amend, stating that the DOTD was not an indispensable party, Tillman was grossly and inexcusably dilatory, and the defendants would be substantially prejudiced by the amendment.
This denial, however, did not sound the death knell for Tillman’s motions. Less than one week before trial, in the course of court-ordered settlement discussions, the trial court informed the defendants that it was considering adding the DOTD as a party defendant and remanding the action back to state court. When court-ordered settlement discussions failed, the trial court fully resuscitated Tillman’s motions for leave to amend and for remand. On the eve of trial, the trial court allowed the joinder of the DOTD as a party defendant. Turning to what it considered to be the concomitant effect of such an addition, the trial court held that the joinder of a state party not amenable to suit in federal court under the Eleventh Amendment 1 destroyed its jurisdiction over the case. Within the same order, the trial court remanded the case back to state court. 2
*1026 In its remand order, the trial court did not expressly cite the remand statute of 28 U.S.C. § 1447(c). 3 Instead, the trial court based its decision to send the ease back to state court on two separate grounds. First, the joinder would destroy its subject matter jurisdiction, necessitating remand, and, second, the court believed that the suit “should be tried before one fact-finder due to the closely interrelated nature of the facts which form the basis of potential liability in this matter.”
Separating the Separable
As a preliminary matter, the appellee contends that the part of the trial court's order granting leave to amend and the part of the order remanding the case must be construed together. The Supreme Court, however, rejected this position in
Waco v. United States Fidelity & Guar. Co.,
Return to Sender?
As this issue will essentially determine the entire disposition of this case, we first consider the appellants’ contention that the trial court erred in remanding the case to state court. However, to reach this issue, we must initially determine whether we may review it, either on appeal or by mandamus.
Reviewability of a remand order depends entirely upon the trial court’s stated grounds for its decision to remand. Remand after removal is controlled by § 1447(c),
4
which provides that “[i]f ... it appears that the district court lacks subject matter jurisdiction, the case shall be remanded. ...” Through the prohibitory effect of 28 U.S.C. § 1447(d),
5
remand orders under § 1447(c) are not reviewable on appeal, by mandamus, or otherwise, except in civil rights cases. See
Gravitt v. Southwestern Bell Tel. Co.,
In its remand order, the trial court never mentioned § 1447(c). However, it is clear from the trial court’s prior orders that it was aware of § 1447(c), as its order of November 1, 1989, declining to add the DOTD, specifically cites both the statute and its amended language verbatim. Oblivious to the amended language in § 1447(c), the appellants contend that we may review the remand order by mandamus because the trial court did not recite the magic words, “improvidently and without jurisdiction,” when remanding the case. As we mention above, that language no longer exists, and while the appellants may still have some attachment to it, it is no longer the basis for remand. Still, the appellants argue that the failure to cite to § 1447(c) places this remand within the small class of cases that fall under the
Thermtron
exception to § 1447(c).
See Thermtron Products, Inc. v. Hermansdorfer,
In
Thermtron,
the Supreme Court slightly enlarged reviewability of remand orders from the narrow constraints imposed by § 1447(d), holding that review is available by mandamus when remand is explicitly based upon grounds other than those specified in § 1447(c). Thermtron’s progeny, however, has construed this exception very narrowly.
See, e.g., Merrimack,
Such is the case here. Although the trial court neither quoted the actual language of § 1447(c) nor cited to the statute, the remand order provided that appellee’s “amendment would destroy subject matter jurisdiction in this court.” This ground comes literally within § 1447(c). Thus, we are precluded from reviewing the remand order on appeal, by mandamus, or otherwise.
See Merrimack,
This preclusion constrains us notwithstanding the fact that the trial court in remanding the case relied on a mistaken assumption — that after adding the DOTD it no longer had jurisdiction. The trial court determined that Tillman’s amended petition “destroyed subject matter jurisdiction because the Eleventh Amendment prohibits *1028 suits by private citizens against the DOTD in federal court.” While it is true that the Eleventh Amendment does create such a prohibition, 7 this prohibition did not deprive the trial court of jurisdiction in this case, as it is well established that the state may waive its Eleventh Amendment immunity by consenting to suit in federal court. 8 The DOTD’s immunity has no effect upon the diversity jurisdiction already established between Tillman, CSX, and Bennett. There is absolutely no basis upon which the trial court could hold that the addition of a state agency that could exercise or waive its Eleventh Amendment immunity would destroy its established diversity jurisdiction over all parties.
Unfortunately for the appellants, like many before them, they may have won the battle, but lost the war. The Supreme Court has expressly held that a remand order based upon lack of jurisdiction,
even if clearly erroneous,
cannot be reviewed.
See Thermtron,
Finally, the appellants’ emphasis on the trial court’s comment on the need to try the case before one fact-finder, a non-§ 1447(c) basis for remand, is unavailing to bring the case within
Thermtron.
The trial court explicitly stated that the destruction of its jurisdiction served as one of its grounds for remand. This sufficiently cloaks the remand order in the § 1447(c) absolute immunity from review.
See Gravitt,
Extra Postage
Regardless of this curious predicament, we turn now to the trial court’s decision to allow joinder of the DOTD. If allowance of the amendment came first, the case at that moment was still ongoing. The DOTD, once added, could have waived its Eleventh Amendment immunity and remained as a party, or if it chose to exercise its immunity, the trial court could have dismissed it so it would no longer even be a party. The DOTD’s temporary presence as a party would not have tainted or obliterated a classic case of diversity. Consequent *1029 ly, the grant of leave to amend was an unreviewable interlocutory order. 9
Still, we feel it necessary to point out that the trial court’s decision to allow joinder, while unreviewable, did not rise to the level of an abuse of discretion. Though the factual scenario seems complicated, the trial court certainly had § 1447(e) discretion to decide whether to allow joinder of the DOTD.
10
In allowing the joinder, the trial court correctly tempered its discretion with the standard established by
Hensgens v. Deere & Co.,
The Dust Settles
Consequently, having been erroneously remanded on § 1447(c) jurisdictional grounds, this case is irretrievably beyond anything we can do about it. We cannot review it by any means. We emphasize our complete inability to do anything about the trial court’s joinder order, whether interlocutory or final, because what we cannot review we cannot by some juridical self-help get back to federal court.
While we point out that the trial court did not abuse its discretion in allowing join-der, this determination only provides extra postage. The mere presence of a § 1447(c) ground as one of the bases for the trial court’s remand has returned this case to sender, without a forwarding address for federal jurisdiction.
For the reasons stated herein, the order granting appellee leave to amend, though not reviewable, was correct, and the correctness of remand is not reviewable even by mandamus.
Appeal Dismissed and Petition for Writ of Mandamus Denied.
Notes
. The trial court’s conclusion that the DOTD could claim Eleventh Amendment immunity from suit brought against it in federal court by a private party is supported by the Supreme Court’s position that "in the absence of consent a suit in which the State or one of its agencies or departments is named as the defendant is proscribed by the Eleventh Amendment.”
Pennhurst State School & Hosp. v. Halderman,
. The trial court’s order reads as follows:
In preparing for trial in this matter, the court has reconsidered its decision denying Plaintiff’s Motion for Leave of Court to Amend Petition and Remand. The court finds that Plaintiff’s case against CSX Transportation, Marler Bennett, and the State of Louisiana through the Department of Transportation and Development (DOTD) should be tried before one factfinder due to the closely interrelated nature of the facts which form the basis of potential liability in this matter.
Fed.R.Civ.P. 15(a) governs amendments to pleadings, and this Rule specifies that "leave of court shall be freely given [to amend] when justice so requires.” Since Plaintiffs proposed amendment would destroy subject matter jurisdiction in this court, the joinder is governed by 28 U.S.C. § 1447(e)_ Here, Plaintiff has a valid cause of action against the DOTD, and thus the purpose of the amendment is not to defeat federal jurisdiction ....
. See note 2, supra. 28 U.S.C. § 1447(c) (as amended) (Supp.1990) provides:
A motion to remand the case on the basis of any defect in removal procedure must be made within 30 days after the filing of the notice of removal under section 1446(a). If at any time before final judgment it appears that the district court lacks subject matter jurisdiction, the case shall be remanded. An order remanding the case may require payment of just costs and any actual expenses, including attorney fees, incurred as a result of the removal. A certified copy of the order of remand shall be mailed by its clerk to the clerk of the State court. The State court may thereupon proceed with such case.
. See note 3, supra.
. Once a case is remanded pursuant to §§ 1447(c), 1447(d) mandates that
[a]n 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 section 1443 [civil rights cases] of this title shall be reviewable by appeal or otherwise.

. The Eleventh Amendment states that: "The Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State.” For application of Eleventh Amendment immunity to state agencies in federal court, see note 1, supra.

Moses H. Cone Memorial Hosp. v. Mercury Constr. Corp.,
. 28 U.S.C. § 1447(e) provides: "If after removal the plaintiff seeks to join additional defendants whose joinder would destroy ... jurisdiction, the court may deny joinder, or permit joinder and remand the action to the State court."
. Though F.R.Civ.P. 15(a) provides that the court should give leave to amend freely when justice so requires, when such joinder would destroy subject matter jurisdiction
justice requires that the district court consider a number of factors to balance the defendant’s interests in maintaining the federal forum with the competing interests of not having parallel lawsuits. For example, the court should consider the extent to which the purpose of the amendment is to defeat federal jurisdiction, whether plaintiff has been dilatory in asking for amendment, whether plaintiff will be significantly injured if amendment is not allowed, and other factors bearing on the equities ...
Hensgens,
.To act within its discretion did not require the court to expressly contradict its previous holding that the DOTD was not an indispensable party. In
Hensgens
this court rejected such an argument, holding that “the balancing of these competing interests is not served by a rigid distinction of whether the proposed added party is an indispensable or permissive party.”
