Nevada's highest court is weighing arguments put forward by casino giant Las Vegas Sands Corp. and disgruntled former Sands executive Steven Jacobs.

The two have been embroiled in a court battle since Jacobs filed a wrongful termination suit in 2010 and accused Sands of a multitude of misdeeds, including doing business with known gangsters and making inappropriate payments to an attorney who was also a Macau lawmaker.

On Wednesday, Jacobs' attorneys asked the Nevada Supreme Court to overturn a decision by a district judge throwing out his defamation suit against Sands CEO Sheldon Adelson.

Sands asked the court to overturn decisions made by the same district judge regarding disclosure of evidence.

After Jacobs filed his suit, Adelson told the Wall Street Journal that his former employee was fired for cause. Adelson added that Jacobs was attempting to explain the termination "by using outright lies and fabrications."

Jacobs, who worked in Macau for the Sands subsidiary Sands China Ltd., responded by amending his original suit to accuse Adelson of knowingly spreading harmful falsehoods.
