No requisite amount, no collection.

The Fifth Circuit concluded that an effort to collect a judgment in federal court failed for lack of a sufficient amount in controversy:

    … As pre-judgment interest has completely accrued during the prior case, this sum can be precisely calculated and does not vary depending on the other awards and when the plaintiff files suit. Because pre-judgment interest is an accrued component of the judgment sued upon at the time the claim to enforce the judgment arose, and because pre-judgment interest’s value does not depend on the passage of time after entry of the state court judgment, pre-judgment interest can be fairly said to constitute an ‘essential ingredient in the . . . principal claim.

As to the post-judgment interest accruing after entry of the Texas Judgment, however, we conclude that it may not be included in determining the amount in controversy in an action to enforce that Judgment. Excluding post-judgment interest from the calculation furthers § 1332(a)’s statutory purpose of preventing plaintiffs from delaying in filing suit until sufficient interest has accrued such that they can reach the jurisdictional amount.
