The 10 Biggest Yahoo! Lawsuits in Company History

The late renowned French judge Montesquieu said the law should be like death, sparing no one. For this reason, giants and pigmies have walked down the corridors of justice, sometimes as plaintiffs, other times as defendants.

One of the giants is Yahoo, a leading internet service provider that has seen its share of legal battles; some it has won, while others it has lost. Among the biggest Yahoo lawsuits in company history, here are ten.

10. SCA Promotions, Inc. v. Yahoo, Inc.

Yahoo sponsored a sweepstake in 2012 with a $5 million award to the person who would correctly predict the winner of all the games in the NCAA Men’s Basketball Tournament. SCA agreed to pay the amount upon Yahoo paying a fee.

Since Yahoo wanted to hold another sweepstake with a $1 billion award, it still sought SCA’s help. SCA charged an 11-million-dollar fee and Yahoo paid $1.1 million. However, later, Yahoo partnered with Quicken which was sponsoring a sweepstakes similar to the one it had planned.

Yahoo sued for breach of contract

SCA filed a lawsuit against Yahoo for breaching the contract; since it had not paid the remaining $9.9 million, it should have paid $4.4 million in cancelation fees. Yahoo countersued for fraud and fraudulent inducement.

Eventually, it was awarded over $1.5 million – $914,000 in attorney fees and $550,000 to refund half the amount it had paid to SCA.

9. Yahoo, Inc. v. National Union Fire Insurance Co. of Pittsburg

According to BBC, a Californian judge ruled senders and receivers of email from Yahoo Mail users from October 2, 2011, were eligible to sue the company as a group.

The plaintiff claimed that Yahoo spied on the emails and used the information to create targeted advertisements that would boost its revenue. Since the breach of privacy lawsuit had over a million members, Yahoo stood to lose millions of dollars.

Yahoo requests National Union Fire Insurance Co. of Pittsburg for coverage

Yahoo asked the insurer to cover the expenses but the insurance company declined. As a result, Yahoo battled the class action lawsuit alone.

Years later, the internet service provider requested the insurance company to reconsider its stand on tendering the defense. National Union Fire Insurance Co. of Pittsburg agreed but only if Yahoo reimbursed any expenses the insurer spent on the defense.

Yahoo sues insurer on the coverage claim

However, Yahoo disagreed and sued the insurance company. The internet company claimed that since the insurer had already rejected the tender initially, it was not liable for reimbursing the expenses. Instead, the internet service provider expected the insurer to pay for the settlement and defense costs.

The judge rejected the breach of contract and bad faith claim, so Yahoo proceeded to trial, where it was awarded $600,000. Still, it was not a satisfactory amount for Yahoo which wanted a multi-million award, but the court declined.

8. Barnes v. Yahoo Inc.

Cecilia Barnes’ love life went sour, and her ex-boyfriend took revenge to another level by posting her nude pictures on a website run by Yahoo. The plaintiff claimed the photos were taken without her knowledge, and her ex created a profile using Barnes’ picture.

On the profile, he revealed Barnes’ real address and telephone number at her workplace. The former boyfriend then used the photos to solicit male correspondents in chat rooms who wound up at Barnes’ workplace expecting sex.

Yahoo sued over nude photos

Barnes emailed her photo ID copy and signed statement to Yahoo so they could take down the profile. She then waited a month for Yahoo and unfortunately, Yahoo did not respond. So, she contacted them again regarding the issue and an executive promised to personally work on resolving it.

Still, no action was taken, resulting in Barnes filing a lawsuit against the internet service provider accusing it of negligence and breaking its promise. Shortly after, the profiles were permanently deleted.

Yahoo found immune against liability

The court ruled that Yahoo was immune against any liability for the ex-boyfriend’s actions. However, Barnes could sue Yahoo for its broken promise. Had Yahoo’s employees been involved in posting the nude photos, then Barnes would have had legal recourse against the company.

7. Checkmate Strategic Group, Inc. v. Yahoo Inc. et al

Checkmate Strategic Group Inc. filed a lawsuit against Yahoo on June 23, 2005, in the California Central District Court where Judge Christina Snyder and Magistrate Judge Fernando Olguin oversaw the case.

The judges approved the settlement and Yahoo also committed itself to collaborate with other internet service providers on the issue of click fraud.

The case attracted the attention of the World Organization for Human Rights which represented the two journalists. Yahoo sought to dismiss the case but later agreed to a private settlement whose details remained confidential.

5. Anderson v. Yahoo Inc.

According to Yahoo Finance, Scott Ard and Gregory Anderson filed a lawsuit against Yahoo alleging that female managers were pushing male employees out of the way to allow female employees climb the corporate ladder.

Lawsuit dismissed

A judge dismissed the claims against Yahoo except for one. The judge agreed there was disparate treatment when Yahoo hired a female employee to be the editor-in-chief before dismissing Ard who was the editorial director. Seeing that Google settled a gender discrimination lawsuit for $118 million, Yahoo was lucky to have the suit tossed.
