Nine environmental groups sue the Trump administration after it rescinds a regulatory definition of “harm.” According to reports, the lawsuit challenges the administration’s decision to remove or revise what counts as “harm” under federal environmental rules, arguing that the change affects how agencies evaluate impacts on protected resources. The groups contend that rescinding the definition would make it harder to enforce existing environmental protections and could reduce the standard used to determine whether activities trigger regulatory requirements or enforcement actions.

The administration’s rescission is presented in the coverage as a change to how government determines qualifying harm for regulatory purposes. Details in the reports focus on the groups bringing the legal challenge and the central issue: the administration’s reversal of the prior definition. The sources describe the case as an effort by environmental organizations to restore or preserve the prior framework they say is necessary for effective oversight. The reports do not indicate an outcome in the courts as of publication, but the lawsuit signals ongoing legal review of the administration’s regulatory approach.
