A written final denial of a claim by the Treasurer may include a general statement of the reason for the denial. Subject to §C, below, a claim shall be deemed to be denied finally if the Treasurer fails to give notice of a final decision on the claim within 6 months after the submission of the claim. Before the beginning of suit and before the expiration of the 3-year period specified in State Government Article, §12-106(b)(3), the Treasurer, upon a written request from the claimant or upon the Treasurer's own initiative, may reconsider a final denial. The claimant's submission of a request for reconsideration does not suspend or toll the period established by State Government Article, §12-106(b)(3), Annotated Code of Maryland, for instituting an action.
