Rule 1253. The act affirmatively imposes upon each carrier the duty of filing with the department all of its tariffs and amendments thereto, as prescribed in the act, or in any rule relative thereto which may be announced by the department, under penalty for failure to do so, and prohibits the use of any rate which is not contained in the carrier's lawfully published and filed tariffs. The fact that receipt of a tariff, or supplement thereto, is acknowledged by the department, or the fact that a tariff, or a supplement thereto, is in the files of the department, will not serve to excuse the carrier from responsibility or liability for any violation of the act, or any ruling lawfully made, which may have occurred in connection with the construction or filing of the tariff or supplement.
