The Seenos have settled three contentious civil lawsuits involving former business associates at a long-dormant Nevada real estate venture.

A Seeno spokesman confirmed late Thursday night that a confidential agreement was reached and that the trio of suits would be dismissed.

James Pisanelli, the Seeno's Las Vegas lawyer, released a statement saying: "The parties have reached a comprehensive settlement of all pending litigation. The financial terms of the settlement are confidential and the Seeno/WNG parties offer no comment as to the litigation or any aspect of the agreement at this time, except that all litigation by and between the parties will be dismissed."

The Seenos' Bay Area companies are still mired in a federal investigation that has led to indictments against an employee and business associates. They also face an environmental charge of installing illegal septic tanks at their Nevada golf course.

In the January 2012 lawsuit that was just settled, the Seenos sued Harvey Whittemore, a former Nevada lobbyist and friend of Senate Majority Leader Harry Reid, alleging he embezzled and misappropriated tens of millions of dollars from their joint company.

Days later, Whittemore and his wife sued Albert Seeno Jr., his brother Thomas Seeno and his son Albert III for $1.8 billion in damages, claiming the Seeno father and son were involved in racketeering, extortion, grand larceny and threats. While no criminal charges were filed, the former Nevada political power broker said Seeno Jr. and his son threatened him and his family, even sending thugs to their homes to force open a safe filled with jewelry and breaking into a house to steal computer equipment.

The Seenos' attorney at the time denied all charges.

In July, Bradley Mamer, the former president and CEO of Wingfield Nevada Group, sued the three Seenos, Michael Ghiorso and Kevin McCauley, asking for more than $500,000 in damages. He accused them of racketeering involving such criminal activities as extortion, tax fraud, and mail and wire fraud. In the lawsuit, Mamer alleged the Seeno-led company ran afoul of environmental regulations, violated tax laws and tried to swap the Nevada land for the Concord Naval Weapons Station. A Seeno spokesman has denied those allegations.

Seeno lawyer Kent Robison confirmed the settlement, telling the Reno Journal Gazette: "The parties have resolved their differences. Period. That's all I can say on the record."

Seeno spokesman Sam Singer said in an e-mail, "The financial terms of the settlement are confidential and the Seeno/WNG parties offer no comment as to the litigation or any aspect of the agreement at this time, except that all litigation by and between the parties will be dismissed."

Whittemore's attorney Dan Bowen said the settlement was "on terms that were acceptable to all parties, including the Whittemores and their family."

Mamer's attorney, Bruce Mundy, said, "Brad is satisfied and is glad to be moving along with his life."

The lawsuits were settled in Clark County District Court.

Whittemore still faces criminal charges in federal court surrounding allegations he used his family and employees to make illegal campaign contributions to Reid in 2007. His trial is May 14.
