Complex Litigation Practice

High-stakes disputes demand investigative rigor and courtroom firepower. BLB&G litigates complex tort and business matters, often in parallel with public enforcement priorities. 

BLB&G’s Complex Torts and Impact Litigation practice represents institutional and individual investors, public and private companies, bankruptcy trustees, creditor committees, and other clients in a broad range of cases. These matters often intersect with public enforcement priorities, and in appropriate cases we work collaboratively with Attorneys General and other government authorities where public and private interests align.

We litigate complex disputes involving financial misconduct, healthcare abuses, environmental harm, digital advertising fraud, privacy rights and bankruptcy-related claims. Leveraging decades of experience, our team brings investigative rigor, industry fluency, and trial-ready advocacy to each matter.

BLB&G’s Complex Litigation team combines experienced first-chair trial lawyers, former prosecutors, and financial and regulatory specialists who work collaboratively from investigation through trial.

Healthcare & Life Sciences

We litigate complex healthcare matters involving pharmacy benefit managers, insurers, medical device manufacturers, and companies participating in government reimbursement systems.

Environmental Litigation

We represent government entities and other stakeholders in litigation arising from environmental misconduct and catastrophic events. These matters often involve complex scientific and regulatory issues, as well as parallel investigations and remediation efforts. We focus on the financial, disclosure, and governance consequences of environmental harm and pursue recoveries that reflect the full cost of misconduct.

BLB&G has pursued claims related to the Vale dam collapse, Volkswagen emissions misconduct, and other environmental compliance failures, addressing the financial and governance consequences of large-scale environmental harm.
