The town of Charlestown responded Monday to a lawsuit from Southwestern New Hampshire District Fire Mutual Aid.
The organization, which fields calls and organizes fire response across town lines, alleges Charlestown owes it money dating back to 2015, when the town moved to start using its own dispatch facility to save money.
But, in a response filed Monday, the town says it paid what it owed the organization and argues the mutual aid organization has changed its rules to make it harder for towns to pull out of their system.
