When a loss of government funds or property occurs while they are in transit or the loss is caused by fire, theft, or other casualty or force majeure, the officer accountable therefor or having custody thereof shall immediately notify the Commission or the auditor concerned and, within thirty days or such longer period as the Commission or auditor may in the particular case allow, shall present his application for relief, with available supporting evidence. Whenever warranted by the evidence, credit for the loss shall be allowed. An officer who fails to comply with this requirement shall not be relieved of liability or allowed credit for any loss in the settlement of his accounts.
