1. Except in counties which frame, adopt and amend a charter for their own government, the compensation of all county officers shall either be prescribed by law or be established by each county pursuant to law adopted by the general assembly. A law which would authorize an increase in the compensation of county officers shall not be construed as requiring a new activity or service or an increase in the level of any activity or service within the meaning of this constitution. Every such officer shall file a sworn statement in detail, of fees collected and salaries paid to his necessary deputies or assistants, as provided by law.

2. Upon approval of this amendment by the voters of Missouri the compensation of county officials, or their duly appointed successor, elected at the general election in 1984 or 1986 may be increased during that term in accordance with any law adopted by the general assembly or, in counties which have adopted a charter for their own government, in accordance with such charter, notwithstanding the provisions of § 13 of Article VII of the Constitution of Missouri.
