Missouri Sunshine Law in Atchison County
Missouri's Sunshine Law is the legal framework governing how Atchison County agencies handle public records. The law lives in Chapter 610 of the Missouri Revised Statutes. It applies to all government bodies in the state, not just police agencies. The Sheriff of Atchison County serves as or designates a Custodian of Records, who is responsible for processing public records requests and ensuring compliance with the law's deadlines and fee rules.
Section 610.011 states the core principle: all meetings, records, and actions of public bodies must be open unless a law specifically says otherwise. This means agencies cannot withhold records unless they can point to a specific legal exemption. The burden is on the agency, not the person making the request. If a record exists and no exemption covers it, access must be granted.
Section 610.023 gives agencies three business days to respond to requests. Section 610.026 caps fees. When an agency wants to deny a request, it must tell you why in writing and identify the specific statute that justifies the denial. If you believe a denial is improper, the Missouri Attorney General's Office can review your complaint. The AG's office has sample request forms and guidance to help you make a proper request from any county agency in Missouri.
