New England federal class action cases in filed in 2025 reflect an ongoing onslaught of cybersecurity and data privacy litigation arising from data breaches and the alleged unauthorized disclosure and/or use of consumer information, including TCPA claims. The most asserted theories underlying data security and privacy class action claims were the exposure of personally identifiable information in a data breach and the receipt of unsolicited telephone calls and text messages. There were also significant levels of case filings based on labor-related claims on behalf of employees, followed by consumer fraud and product liability claims, civil rights suits filed against government defendants, and antitrust claims. These trends are consistent with those observed in federal filings throughout 2024, apart from a marked rise in civil rights class action activity.
