The board shall have the power to bring an action to enjoin any person, firm, or corporation who, without being licensed or issued a permit by the board, dispenses hearing aids in this state. The action shall be filed in the county in which such person resides or practices or in the county where the firm or corporation maintains an office or practices. If it shall appear that the person, firm, or corporation is guilty of dispensing hearing aids without a license or permit issued by the board, then such person, firm, or corporation shall be enjoined from dispensing hearing aids without a valid license or permit throughout the state. It is declared that such unlicensed activities are a menace and a nuisance and are dangerous to the public health, safety, and welfare; and, therefore, it shall not be necessary, in order to obtain relief, as provided in this Code section, for the board to allege or prove that there is no adequate remedy at law.
