Under what circumstance can a notary's commission be suspended or revoked?

A notary's commission can be suspended or revoked due to a conviction of a felony involving moral turpitude. This is because moral turpitude encompasses behaviors that are considered contrary to community standards of justice, honesty, and good morals. Such a conviction indicates a serious breach of ethics or integrity, which is fundamental to the role of a notary public. Notaries are expected to uphold the law and demonstrate high moral character, so a felony conviction in this category directly undermines their ability to perform their duties.

The other options do not pose the same level of threat to the integrity or legality of the notarial act. For instance, while notarizing without a witness may raise questions about the validity of the notarization, it doesn't inherently lead to a suspension or revocation unless there are specific legal violations associated with that action. Notarizing for a family member may be seen as a conflict of interest, but it is not an outright reason for revocation since specific laws may allow it under certain conditions. Similarly, charging lower fees for friends does not violate rules or ethics associated with notarial duties, as long as the fees remain within legal limits.
