Are State Officers or Public Officers under duty to declare their wealth?

Yes. The Public Officer Ethics Act requires Public Officers to make true and correct declarations of their incomes, assets and liabilities once every two years. All State Officers are Public Officers but not all Public Officers are State Officers. All Public Officers must also declare all incomes, assets and liabilities of their spouse(s) and children below eighteen (18) years of age. Under Article 260 of the Constitution, a Public Officer refers to any State Officer or any other person holding a public office.
