28 USC 1447: Remand Deadlines, Procedure, and Appeals

Under 28 U.S.C. 1447, a motion to remand is how a plaintiff asks a federal court to return a removed case to state court, and the statute controls both the deadline for filing and whether the ruling can be appealed. Procedural objections have to be raised within 30 days of removal or they are waived. Objections based on the federal court’s lack of subject matter jurisdiction can be raised any time before final judgment, and the court must remand on its own if it spots the problem. Most remand orders cannot be appealed, though a handful of narrow exceptions exist.

When a Federal Court Must Send a Case Back

Section 1447(c) directs a federal court to remand a removed case in two situations: when it lacks subject matter jurisdiction, or when the plaintiff timely raises a procedural defect in the removal.{¹}

Jurisdictional defects are the most fundamental. A defendant can only remove a case the federal court could have heard in the first place, meaning one with federal question jurisdiction under 28 U.S.C. 1331 or diversity jurisdiction under 28 U.S.C. 1332.{²}{³} For federal question cases, jurisdiction must appear on the face of the plaintiff’s complaint under the well-pleaded complaint rule of Caterpillar Inc. v. Williams, 482 U.S. 386 (1987); a federal defense does not suffice.{⁴} For diversity cases, the parties must be citizens of different states and the amount in controversy must exceed $75,000, measured at the time the case was filed. A later change in a party’s citizenship cannot cure a defect that existed at filing, as the Supreme Court confirmed in Grupo Dataflux v. Atlas Global Group, L.P., 541 U.S. 567 (2004).{⁵}

Procedural defects are the second category. Common examples include:

A notice of removal filed more than 30 days after the defendant received the initial pleading or summons, whichever is shorter.{}⁶
Failure to obtain the consent of every properly joined and served defendant, the unanimity rule applied in Getty Oil Corp. v. Insurance Co. of North America, 841 F.2d 1254 (5th Cir. 1988).{}⁷
Violation of the forum defendant rule, which bars removal of a diversity case when any properly joined and served defendant is a citizen of the state where the suit was filed.{}⁸
Removal of a diversity case more than one year after the suit was filed, unless the plaintiff acted in bad faith to prevent removal.{}⁶

Courts generally disregard the citizenship and consent of nominal parties — those named in the suit with no real stake in the outcome — when assessing diversity and unanimity.

Filing Deadlines for a Motion to Remand

The deadline depends entirely on the type of defect.

The 30-Day Rule for Procedural Defects

A motion based on any procedural defect must be filed within 30 days after the notice of removal.{¹} Miss the window and the objection is waived, even if the defect was clear. The Fifth Circuit applied this rule in Baris v. Sulpicio Lines, Inc., 932 F.2d 1540 (5th Cir. 1991), where the plaintiff’s late motion allowed the federal court to keep the case.

No Time Limit for Jurisdictional Defects

Subject matter jurisdiction works differently. If the federal court lacks jurisdiction, the statute says it “shall” remand at any time before final judgment.{¹} The court can act on its own initiative, and a party can raise the issue at any point. Jurisdiction cannot be waived or created by consent, so a federal court that discovers the defect halfway through trial still has to send the case back.

Costs and Attorney Fees

When granting remand, the court may order the removing party to pay the plaintiff’s costs and actual expenses, including attorney fees.{¹} In Martin v. Franklin Capital Corp., 546 U.S. 132 (2005), the Supreme Court held that fees should be awarded when the removing party lacked an objectively reasonable basis for removal, and denied when a reasonable basis existed.{⁹} A defendant who makes a good-faith jurisdictional argument usually will not face a fee award even if the court disagrees. Fees tend to be reserved for removals with no real legal footing.

What Happens After the Remand Order Issues

Once remand is ordered, the clerk mails a certified copy of the order to the state court clerk, and the federal court’s authority over the case ends.{¹} The state court picks up the case in the same procedural posture it was in at the time of removal.

Motions, pleadings, and rulings entered while the case was in federal court remain part of the record unless the state court decides otherwise. State courts generally respect substantive rulings under principles of comity and judicial efficiency, but they have authority to reassess procedural determinations under their own rules. If the federal court dismissed certain claims before remand, the state court decides under state procedural law whether those dismissals stand; no federal rule requires it to honor every interim ruling. If discovery deadlines lapsed during the federal detour, expect a new scheduling order.

Whether You Can Appeal a Remand Order

Appellate review of remand orders is one of the most restricted areas in federal procedure. Section 1447(d) states the default flatly: a remand order is not reviewable on appeal or otherwise.{¹} Congress designed the bar to prevent parties from bottling cases up in federal court through appeals. The exceptions are narrow but important.

Federal Officer and Civil Rights Cases

The statute allows review of remand orders in cases removed under 28 U.S.C. 1442, which covers federal officers or agencies sued for acts under color of office, and 28 U.S.C. 1443, which covers certain civil rights cases.{¹⁰}{¹¹} In BP P.L.C. v. Mayor and City Council of Baltimore (2021), the Supreme Court held that when a defendant removes on multiple grounds including at least one under Section 1442 or 1443, the appeals court can review the entire remand order, not just the portion addressing the federal officer or civil rights ground.{¹²}

Discretionary Remands of State Law Claims

When a federal court declines to exercise supplemental jurisdiction over state law claims and remands them — typically after the anchor federal claim drops out — that order is not a Section 1447(c) remand for lack of subject matter jurisdiction. In Carlsbad Technology, Inc. v. HIF Bio, Inc., 556 U.S. 635 (2009), the Supreme Court held that such discretionary remands fall outside the appellate review bar and can be reviewed on appeal.{¹³}

Class Action Fairness Act Appeals

Class actions removed under CAFA get a separate appeal path. Under 28 U.S.C. 1453, a court of appeals may accept an appeal from a remand order in a CAFA case if the party applies within 10 days of entry of the order.{¹⁴} The appeals court has discretion over whether to hear the appeal, but this is far more access than standard removal gets.

Mandamus for Unauthorized Remands

When a district court remands on grounds not authorized by Section 1447(c), the aggrieved party can seek a writ of mandamus. In Thermtron Products, Inc. v. Hermansdorfer, 423 U.S. 336 (1976), the Supreme Court held that only remands invoking the statutory grounds in Section 1447(c) are immune from review; a remand based on non-statutory reasons, such as a crowded docket, can be challenged through mandamus.{¹⁵} Courts grant mandamus sparingly, typically only when the district court clearly exceeded its authority and no other adequate remedy exists.
