ClassAction.com attorney John A. Yanchunis will serve as Lead Counsel on the largest class action lawsuit in history—the Yahoo data breach that allegedly compromised the private data of hundreds of millions of people around the world.

In an order filed Thursday, February 9, 2017 in the Northern District of California, U.S. District Judge Lucy H. Koh appointed John A. Yanchunis of Morgan & Morgan and ClassAction.com to serve as Lead Plaintiffs’ Counsel and Chair of the Plaintiffs’ Executive Committee.

Read the Order

Four firms filed motions to serve as lead counsel: Morgan & Morgan, Kaplan Fox & Kilsheimer LLP, Kessler Topaz Meltzer & Check LLP, and Susman Godfrey LLP. At a hearing in San Jose before Judge Koh made her decision, Mr. Yanchunis argued that a large firm of Morgan & Morgan’s stature—with more than 300 attorneys at its disposal—would be the best choice to take on a case of such magnitude.

At a press conference Saturday, Mr. Yanchunis said, “Morgan & Morgan is the biggest law firm of its type in the country. We have the legal talent and financial strength to take on anyone in this country.”

Mr. Yanchunis also noted that Morgan & Morgan (motto: "For the People") only represents consumers, and never large companies.

Yahoo’s 2013 data breach (announced last year) compromised the data of roughly one billion users. A separate breach in 2014 compromised the data of 500 million users.

Mr. Yanchunis said Saturday that the lawsuit will represent everyone in the world whose data was breached.

Yanchunis Heads Five-Person Executive Committee

The other firms that filed motions to serve as lead counsel argued that the case was not as complex as it appeared, despite its mammoth size. They also claimed that a single firm should work the case, instead of the committee of firms helmed by Mr. Yanchunis.

Judge Koh thought they made “excellent points,” but ultimately disagreed.

Joining Mr. Yanchunis on the Executive Committee are Gayle Blatt of Casey Gerry Schenk Francavilla Blatt & Penfield LLP, Stuart Davidson of Robbins Geller Rudman & Dowd LLP, Karen Riebel of Lockridge Grindal Nauen PLLP, and Ariana Tadler of Milberg LLP.

As Lead Counsel and the Plaintiffs’ Executive Committee, Mr. Yanchunis and the abovementioned attorneys must review and record all billing records and “impose and enforce limits on the number of lawyers assigned to each task,” among other key duties.

Lawsuit Seeks Tighter Security, Hundreds of Millions in Damages

At the press conference, Mr. Yanchunis cited the long gap between the breaches and their announcement as one of the most concerning aspects of Yahoo’s actions.

"Those breaches either remained undetected or Yahoo failed to inform the public [for years]."

“What’s alarming about this is that the first breach occurred in 2014, but Yahoo did not announce it until September of 2016,” Mr. Yanchunis said. “The breach announced in December occurred in 2013. And yet, those breaches either remained undetected, or Yahoo failed to inform the public about the breaches.”

He also noted that most states have laws on the books requiring companies to inform consumers of data breaches within 30 days of discovering them.

Mr. Yanchunis said the lawsuit will seek stronger cybersecurity measures from Yahoo “to make sure that this never happens again.” Moreover, for those who suffered financial losses as a result of the breach, the lawsuit will seek damages.

Asked how much those damages might total, Mr. Yanchunis said it’s too early to say, but likely in the hundreds of millions of dollars.

“It will be extensive,” he said.

Experience with High-Profile Breaches Proved Crucial

In determining whom to name Lead Counsel for the largest class action ever, Judge Koh weighed the following chief criteria:

  • “Knowledge and experience in prosecuting complex litigation, including class actions, data breach, and/or privacy cases”
  • “Willingness and ability to commit to a time-consuming process”
  • “Ability to work cooperatively and efficiently with others”
  • “Access to sufficient resources to prosecute the litigation in a timely manner”
  • “Commitment to prioritizing the interests of the putative class”

The first criterion, experience, may have clinched the win for Mr. Yanchunis. He and Morgan & Morgan previously litigated two massive data breach cases—the Home Depot Inc. and Target Corp. cases. Those lawsuits were settled for $19 million (Home Depot) and $10 million (Target), respectively.

Now Mr. Yanchunis and his team will take on the biggest breach of all, and aim to hold Yahoo accountable for allegedly endangering the privacies and identities of hundreds of millions of people.
