CBF's Litigation Department uses carefully chosen legal action as another tool for advancing the restoration and protection of the Chesapeake Bay, its rivers, lakes, and streams.

Litigation is used to not only protect and enforce the current environmental laws but to bring about environmentally friendly change within our legal system. CBF attorneys argue cases in the federal and state courts within the watershed and file amicus curiae—also calledFriend of the Court—briefs in related environmental lawsuits.

Carefully executed litigation serves three primary purposes:

  • It spurs enforcement efforts against those who violate laws that were created to protect the watershed.
  • It helps define and drive the agenda for public debate over restoration and protection of the Bay.
  • It delivers concrete and enforceable progress in resource restoration.

Learn more about CBF's active cases, concluded cases, amicus curiae (friend of the court) briefs, and relevant judicial decisions.

Litigation attorneys and staff work directly with CBF's Environmental Protection and Restoration Department to file comment letters on federal regulations. We focus on regulations that will have an impact on the Chesapeake Bay and its tributaries, human health impacts, as well as impacts to low income communities and communities of color that are disproportionally harmed by pollution and other environmental threats. More detail on the regulations and comment letters can be found on our Federal Regulations page.
