In court filings, the 72 plaintiffs alleged that employees of L-3 Services tortured and abused them. They said the tactics included beatings, forced nudity, exposure to extreme temperatures and keeping detainees awake for long hours.

The company, now called Engility Corporation, asked for the case to be dismissed, arguing its personnel were part of "occupying forces" and thus not subject to civil lawsuits. A federal court denied the motion in 2010, and last year an appeals court dismissed the company's bid to overturn the decision.

The plaintiffs accepted a $5.28 million payment in October to resolve the case.
