This subtitle does not affect any other requirement as to notice, including a time that is specifically set for the publication of the notice. A unit shall submit a notice that sets a date for a hearing or meeting or for the termination of the opportunity to be heard in time for publication in an issue of the Register that will be published: on or before the date set by law for publication of the notice; or if the date for publication is not set by law, at least 15 days before the date for the hearing or meeting or for the termination of the opportunity to be heard. As to a notice that paragraph (1)(ii) of this subsection governs, publication of the notice less than 15 days before the date for a hearing or meeting or the termination of the opportunity to be heard does not prejudice the effectiveness of the notice, if notice of less than 15 days is reasonable. Unless notice by publication is insufficient in law, a notice that sets a date for a hearing or meeting or for the termination of the opportunity to be heard and that is submitted as required by this subsection constitutes, on publication, notice to: each person who resides in the State; or each person who holds an interest in property in the State. Publication of a notice as required by this subtitle and as required by any other provision of the Code are both necessary to constitute full compliance with law.
