permitting towns to unilaterally withdraw from a cooperative school district.

HB 1644 allows any single town within a cooperative school district to initiate withdrawal from the district without needing approval from the entire district. Previously, a 3/5 supermajority vote of all district voters could block a town's withdrawal; this bill removes that requirement. The process now begins when a town's voters approve withdrawal by a 3/5 majority at a town meeting, after which the state board reviews the withdrawal plan. This change directly affects towns in cooperative school districts by giving them unilateral authority to leave the arrangement.
