What it's about

It found the district court erred and the Tenth Circuit abused its discretion by denying review, wiped out the Tenth Circuit’s order (vacated it), and sent the case back to that court (remanded).

Owens's case was a class action that Dart Cherokee sought to move from state court to federal court. The district court sent it back to state court because the notice lacked evidence about the amount at stake.

The amount at stake was one requirement for a federal court to hear this class action.

Question presented

Is a defendant seeking removal of a case to federal court required to provide evidence supporting federal jurisdiction in the notice of removal?

What the Court decided

Holding

1. As specified in §1446(a), a defendant’s notice of removal need include only a plausible allegation that the amount in controversy exceeds the jurisdictional threshold; the notice need not contain evidentiary submissions. Section 1446(a) tracks the general pleading requirement stated in Rule 8(a) of the Federal Rules of Civil Procedure. By borrowing Rule 8(a)’s “short and plain statement” standard, corroborative history indicates, Congress intended to clarify that courts should “apply the same liberal rules [to removal allegations as] to other matters of pleading.” H. R. Rep. No. 100–889, p. 71. 2. The District Court erred in remanding this case for want of an evidentiary submission in the notice of removal, and the Tenth Circuit abused its discretion in denying review of that decision. Pp. 7– 14. Vacated and remanded.

Result
Vacated

The Court's reasoning

The Court said the law for moving a case to federal court uses the same basic “short and plain statement” standard as other court filings. It concluded that a plausible claim about the amount at stake meets that standard, without evidence attached.
