§ 3. The legislature shall, by general law, conform all charters of
savings banks, savings and loan associations, or institutions for
savings, to a uniformity of powers, rights and liabilities, and all
charters hereafter granted for such corporations shall be made to
conform to such general law, and to such amendments as may be made
thereto. The legislature shall have no power to pass any act granting
any special charter for banking purposes; but corporations or
associations may be formed for such purposes under general laws.
