Revise district court laws

This bill reorganizes Montana's judicial districts by combining the 10th and 14th districts into a single 10th district and renumbering the former 15th district as the 14th, while adding a ninth judge to the 13th district in Yellowstone County. The legislation amends state statutes to reflect these changes and establishes a transition process where any vacancy in the combined 10th district would be left unfilled, with the remaining judge serving the merged district instead. Additionally, the bill mandates a special election in November 2030 to select the new judge for the 13th district, with the reorganization taking effect either immediately or upon the occurrence of a vacancy in the affected districts, whichever happens first.
