It is the intent of the General Assembly that the authority exercised under Article XI–F, § 8, of the Maryland Constitution, to limit the rate of property tax that a code county may impose or regulate the maximum amount of indebtedness that a code county may incur, be exercised only when there is the possibility that the code county is imposing an excessive rate of property taxation or is incurring indebtedness in an excessive amount.
