Senate Bill No. [insert bill number] aims to revise the legal requirements for standing in lawsuits within the state of Montana. The bill establishes that the judiciary's authority is limited to adjudicating claims where the claimant has and maintains legal standing, which is defined by three key elements: injury, causation, and redressability. The bill specifies that a claimant must demonstrate a specific, real, and concrete injury or an immediate threat of injury caused by the party being sued, and that the court has the power to grant effective relief. It further clarifies that generalized grievances, speculative threats, or claims based solely on public importance do not suffice to establish legal standing.

The bill introduces several new sections that codify these requirements, including definitions and limitations on what constitutes legal standing. It also includes provisions for the effective date of the act, which is set for July 1, 2025, and specifies that the act will apply to legal proceedings initiated on or after this date. Overall, the legislation seeks to reinforce traditional standing rules and ensure that courts do not overstep their constitutional authority by deciding cases where the parties lack the necessary standing.
