Elections-voting machine and voting system tests.
SF 28 requires that all voting machine and electronic voting system tests in Wyoming be conducted publicly, with county clerks providing at least five days' notice to the public and political parties before testing. It removes the previous presumption that machines are properly prepared, allowing challenges within two days of sealing. Each voting machine must be individually tested and certified, including accuracy verification using pre-audited ballots at least two weeks before an election. The bill also updates county clerk procedures to ensure transparency and accountability in election equipment preparation.

MODERATE
The bill was finalized as an enrolled act, changing the header from a draft Senate File to an official Enrolled Act No. 66. Substantively, the bill clarifies that voting machine tests must be open to the public and removes the legal presumption that machines are properly prepared if certified by the county clerk. It also tightens the timeline for challenging machine certification, requiring complaints to be filed within five days of sealing instead of two. Additionally, the notice period for testing was reduced from five days to two days, and the testing process now explicitly requires the use of preaudited paper ballots to verify accuracy.
Scope change
The bill's scope remains focused on election administration in Wyoming counties, but the applicability of the 'proper preparation' presumption is now explicitly limited to machines that are publicly tested and sealed.
REQUIREMENT
Removed the legal presumption that a voting machine is properly prepared upon certification, requiring public testing to validate accuracy.
Added specific requirements for tests to include preaudited paper ballots and scenarios with overvotes and undervotes to verify tabulating equipment accuracy.
Updated the notice procedure for electronic voting system tests to include notification of the state chairman of political parties.
TIMELINE
Reduced the notice period for voting machine tests from five days to two days before the test occurs.
ENFORCEMENT
Changed the deadline for challenging a machine's certification from two days to five days after the machine is sealed.
