What the court wrote

Verbatim from the court's document (public domain). Ellipses mark omitted text; nothing is paraphrased.

As a preliminary matter, the County moved for leave to file a corrected reply brief. ECF No. 44. Although the Court agrees withArmstrong'sassessmentthatthemotionwasnecessitated bytheinclusionofafictitiouscase,ECFNo. 47at2,theCourt does not have more information as to why that happened. Regardless, the County caught and corrected the error the same day, meaning that there is no prejudice in allowing the correction. Further, the County's original reply brief included real case law in support of the proposition that the County sought to make, meaning that the fictitious case would be redundant even if it were real. Thus, the Court will grant the County's motion to amend and correct the brief, ECF No. 44, and has considered the corrected brief, ECF No.
