Generally revise laws relating to challenges brought under MEPA

This bill amends Montana's environmental protection laws by adding a $240 court filing fee specifically for challenges to agency decisions under the Montana Environmental Protection Act. It also requires agencies to act quickly after a court remands a case and limits future challenges to only new issues that arise after the initial decision. Additionally, the bill shifts the responsibility for record preparation costs to plaintiffs and prohibits courts from awarding fees and costs in these environmental challenge cases. These changes directly affect individuals and organizations that file lawsuits against state agencies regarding environmental decisions.
