What can lead the Registrar to revoke a license after the fact?

The revocation of a license by the Registrar can occur due to the late discovery of grounds that justify denying the initial application. This means that if issues or violations are uncovered after a license has been granted—such as disciplinary actions, criminal convictions, or other disqualifying factors—the Registrar has the authority to revoke the license. The integrity of the licensing process relies on the ability to ensure that all licensees meet required standards throughout their practice. If new information comes to light that indicates the license should not have been issued in the first place, this serves as a valid basis for revocation.

In this context, the other choices do not provide sufficient grounds for revocation. For instance, late charges or fees are generally not related to the competency or eligibility to hold a license. Similarly, failing to submit a renewal application, while serious, typically results in expiration rather than immediate revocation of an active license that had previously met all criteria. Lastly, the rejection of a contractor's project proposal is a business decision and does not inherently affect the validity of a license itself.
