Maryland Code, Natural Resources § 4-613

(a) The Department may suspend a person's angler's license if it is transferred to another person or used or presented to a law enforcement officer by a person other than the person to whom it was issued, pending the disposition of a criminal proceeding against the other person.

(b) In addition to any penalty provided in this title, if any person is convicted of fishing without a proper angler's license in his possession, or using another person's angler's license, the angler's license shall be rendered void. The person upon whom the angler's license is found and the licensee may not procure an angler's license for 1 year following the date of conviction. However, the provisions of this section do not apply to a licensee who does not knowingly give his license to another.
