The Tribunal finds, inter alia, that the Applicant’s act of altering the number of hours he had worked without the authorization of his first reporting officer amounted to inexcusable alteration of official documents and material misrepresentation of facts. The principle of proportionality means that an administrative action should not be more excessive than is necessary for obtaining the desired result. The requirement of proportionality is satisfied if a course of action is reasonable, but not if the course of action is found to be excessive.
