Representative Cases:

Qui Tam Lawsuit Against Advanced Biohealing, Inc.

Represented a whistleblower who brought a qui tam lawsuit under the False Claims Act against Advanced Biohealing, Inc. (“ABH”), alleging that ABH utilized illegal kickback schemes to sell its product, Dermagraft, to hospitals operated by the U.S. Department of Veterans Affairs. That lawsuit resulted in a number of criminal convictions, as well as a settlement pursuant to which pharmaceutical company Shire, which had purchased ABH, agreed to pay $350 million to federal and state governments—one of the largest settlements ever in a kickbacks case.

Qui Tam Lawsuit Against Victaulic Company

Represented whistleblower in False Claims Act qui tam case against Victaulic Company (“Victaulic”), which alleged that Victaulic had imported pipe fittings without proper country-of-origin markings, and without paying “marking duties” owed as a result.  The case resulted in an historic ruling from the United States Circuit Court for the Third Circuit, which held for the first time that country-of-origin marking violations could be pursued in qui tam cases under the False Claims Act, and which firmly established, more generally, the an importer’s failure to pay customs duties is a violation of the False Claims Act’s “reverse false claims” provision.  The lawsuit subsequently settled on confidential terms.

Qui Tam Lawsuit Against Orbit Medical Inc. and Rehab Medical Inc.

Represented two whistleblowers who brought a qui tam lawsuit under the False Claims Act against defendants Orbit Medical Inc. and Rehab Medical Inc. alleging that Orbit sales representatives, under the direction of one of Orbit’s top executives, Jake Kilgore, forged medical records so that Orbit could obtain payment from Medicare for electric wheelchairs. This qui tam lawsuit resulted in a settlement worth more than $7.5 million, and also a number of criminal convictions.

Qui Tam Lawsuit Against Arbon Equipment Corporation and Rite-Hite Holding Corporation

Represented a whistleblower who brought a qui tam lawsuit under the False Claims Act against defendants Arbon Equipment Corporation (Arbon) and Rite-Hite Holding Corporation (Rite-Hite). The lawsuit alleged that Arbon and Rite-Hite violated “prevailing wage laws,” which include the federal Davis-Bacon Act and Service Contract Act, and certain provision of the California Labor Code. These prevailing wage laws require contractors and subcontractors working on certain types of government-funded projects to pay employees working on those projects specified hourly wages that are higher than minimum wage, and often higher than the employees would be paid for doing similar work on private projects. The action brought by a former Arbon employee, alleged that Arbon and its parent company, Rite-Hite, failed to pay prevailing wages to employees who installed and serviced loading dock equipment at facilities owned by the federal or California state governments. Pursuant to the terms of a settlement, the Defendants paid a total of $4,000,000 and agreed to change their compensation practices and policies to assure compliance with federal and California prevailing wage laws.

Qui Tam Lawsuit Against CXtex

Represented a whistleblower who brought a qui tam lawsuit under the False Claims Act against Cablexpress Corp. d/b/a/ CXtec, alleging that the company violated the Trade Agreements Act by knowingly selling products to U.S. government agencies that were manufactured in China and other non-approved countries. The lawsuit resulted in substantial payments by CXtec to the United States government; the exact terms of the settlement are confidential.
