In brief
Overview
According to Donnal M. Lach, the case concerns whether Congress intended to include local governments within the definition of “person” under the False Claims Act.
According to Donnal M. Lach, the False Claims Act has both criminal and civil provisions, with the criminal provisions codified separately since 1878.
According to Mr. Stewart, local governments receive substantial federal funds, and fraud by them can cause harms similar to private parties.
Since 1986, 138 qui tam suits have been filed against local governments, with the United States intervening in 13 of them.
The Treasury has recovered over $10 billion from False Claims Act suits since 1986.
Background and question before the Court
According to Donnal M. Lach, the central question is whether the term “person” in the False Claims Act includes local governments.
According to Donnal M. Lach, the Court previously held in Stevens that the definition of “person” has remained unchanged since the original enactment in 1863.
What each side argues
Cook County, Illinois (Petitioner)
According to Ms. Lach, local governments were not intended to be covered as fraudsters under the False Claims Act when Congress expanded it in 1986.
United States (Respondent)
According to Mr. Stewart, fraud by local governments causes the same harms as comparable misconduct by private parties, justifying their inclusion under the False Claims Act.
What happened at oral argument
Chief Justice Rehnquist asked whether the Sherman Act applies to municipalities.
What the Court decided
Why it matters
According to Donnal M. Lach, determining whether local governments are “persons” under the False Claims Act will affect the government’s ability to pursue qui tam actions against them.
According to Mr. Stewart, local governments receive large amounts of federal funding, and fraud by them can cause significant losses to the Treasury.
Since 1986, the Treasury has recovered over $10 billion from False Claims Act suits, highlighting the financial stakes involved.
