Del. Code tit. 21, § 2312

If the Department determines that an applicant for a certificate of title to a motor vehicle is not entitled thereto, it may refuse to issue such certificate and, in that event, unless the Department reverses its decision or its decision is reversed by a court of competent jurisdiction, the applicant shall have no further right to apply for a certificate of title on the statements in said application. The Department may, for a like reason, revoke any outstanding certificate of title.
