Which of the following events can lead to the suspension or revocation of a notary commission?

The option that states the secretary of state suspends or revokes a notary commission is correct because the authority to suspend or revoke a notary's commission ultimately lies with the secretary of state. This may occur for various reasons, such as misconduct, failure to comply with the duties and responsibilities required of a notary, or violation of notary laws. The secretary of state oversees the registration and conduct of notaries within Illinois, ensuring they adhere to the legal and ethical standards expected of them.

The other options may not directly lead to suspension or revocation. For instance, moving to another state typically does not cause an immediate revocation but instead would require a notary to seek a commission in the new state. An expired commission may necessitate renewal but does not result in automatic revocation. Failing to perform duties might be a cause for concern, but it is the oversight and enforcement from the secretary of state that ultimately addresses any failures. Thus, the authority of the secretary of state in this context is paramount for enforcement action against notaries.
