The latest draft of Vermont's version of the Revised Uniform Law on Notarial Acts, being considered by the Vermont Legislature, may be found here (PDF). One thing that bothered me was that it didn't mention, near the beginning of the bill, whether notaries would still be considered government officers. However, throughout the bill, notaries are referred to being "commissioned", which is a term usually applied to an official. Also, § 5341(c) requires an applicant for a notary commission to "execute an oath of office" before a commission can be issued, which makes it reasonably clear the notary is a government officer.
Given that, the next question is which branch of government the notary belongs to.
