The bill aims to revise existing laws related to lawsuits for environmental actions, specifically focusing on limitations for challenging licenses or permits issued for mining, oil, or gas activities. It establishes that legal actions seeking to review decisions made by the department regarding these licenses or permits must be filed within 90 days of the decision, with summons issued and served within 60 days of filing. Additionally, it mandates that challenges must be brought in the county where the proposed activity is to occur and requires that any judicial challenge must include the party to whom the license or permit was issued. The bill also stipulates that only one action may be brought on a specific exploration license or operating permit, and it prioritizes judicial challenges for projects exceeding $1 million in costs.

Furthermore, the bill repeals Section 82-4-349 of the Montana Code Annotated, which previously addressed limitations of actions and venue. It includes provisions for the award of attorney fees and costs if a court finds that a challenge was without merit or intended to harass or delay. The act is set to take effect immediately upon passage and approval, applying to all licenses and permits issued under Title 82 from that date forward.
