MO SB478

Establishes the "Uniform Electronic Legal Material Act" applying to electronic publication of Missouri's Constitution, statutes, session laws, agency rules, state regulations, court decisions, and court rules first published electronically on or after August 28, 2013

Requires official publishers (the revisor of statutes for constitutional and statutory materials, the secretary of state for regulations published in the Missouri code, and adopting agencies for unpublished rules) to authenticate electronic legal material by providing users a method to verify the record is unaltered from the official version

Designates authenticated electronic legal material as presumed accurate copies, with any party challenging authentication bearing the burden of proving by preponderance of evidence that the record is not authentic

Mandates official publishers preserve and secure electronic legal material in electronic or non-electronic form, ensuring record integrity, backup and disaster recovery, continuing usability, and permanent public availability

Directs official publishers to consider standards and practices from other jurisdictions, national standard-setting bodies, user needs, and compatibility with other official publishers when implementing these provisions
