In an article for The Circuit Rider, Partner David Greenwald discusses the challenge companies face in preserving attorney-client privilege and work product protections regarding the work of cyber breach consultants during data breach investigations. Since 2015, courts have compelled disclosure of cyber consultant materials in nine out of twelve cases discussed in the article.  The most salient difference is that the companies that were able to protect privilege established two separate work str

The US Supreme Court today delivered a “complete victory” to our clients and affirmed the 2022 decision of the North Carolina Supreme Court in Moore v. Harper, a consolidation of three cases stemming from North Carolina’s redistricting process.

On January 9, 2023, the US Supreme Court heard oral argument in the matter of In re Grand Jury, No. 21-1397, which asked the Court to determine when the attorney-client privilege will protect “dual-purpose communications” that involve both legal and business advice. The Court’s decision could affect how privilege will apply to the daily work of in-house counsel, and other lawyers, who regularly wear both legal and business hats for their clients.

Today, Jenner & Block filed a Supreme Court brief in Moore v. Harper, continuing its advocacy for free and fair election maps on behalf of its client, the North Carolina League of Conservation Voters.

On October 3, 2022, the U.S. Supreme Court granted review in a federal grand jury proceeding that may result in the Court expanding the scope of the attorney-client privilege for dual-purpose business communications. Petitioner argues that the Court should adopt the test articulated in two decisions by the U.S. Court of Appeals for the D.C. Circuit, which were authored by then Judge Brett Kavanagh. 

On June 30, the US Supreme Court granted writ of certiorari in Moore v. Harper, a case arising from the North Carolina General Assembly’s efforts to gerrymander new congressional maps. Jenner & Block represents the North Carolina League of Conservation Voters in its fight for free maps and fair elections, in opposition to the General Assembly’s efforts. 

Cyber attacks are increasingly frequent and virulent. An intruder may lurk in a company’s computer system for years, or an attack may be sudden and catastrophic. Millions of people’s personal information and companies’ sensitive and proprietary data may be stolen and sold to the highest bidder. And disclosure of a breach ineluctably leads to class action and other civil litigation. 

Jenner & Block represented the North Carolina League of Conservation Voters, which, along with other plaintiffs, argued that the state’s congressional and legislative election maps were unconstitutionally gerrymandered. After the team prevailed in the North Carolina Supreme Court, state courts approved redrawn maps that treat all voters fairly regardless of party, race, or region.

A Jenner & Block team secured a victory when the North Carolina Supreme Court declared that the General Assembly’s gerrymandered Congressional and state legislative maps were unconstitutional beyond a reasonable doubt and barred them from being used in future elections.
