In response, Sprint argued that claims based on pre-2010 conduct violate the ex post facto clause of the U.S. Constitution. The ex post facto clause prohibits Congress and the states from enacting any law that, among other things, retroactively imposes a punishment for an act that was not punishable when it was committed. After a lengthy analysis, the court concluded that “[The statute], like its federal counterpart, is not sufficiently punitive in nature and effect as to warrant preclusive application of the ex post facto clause prior to Aug. 10, 2010, when the act was amended to expressly apply to knowing violations of the tax law.” Although the decision is likely to be appealed, for now, the ruling opens the door to FCA cases with allegations that predate the 2010 amendments.
