The comptroller is hereby authorized and empowered, with the approval of the governor and the attorney general, to alter or modify the requirements of all existing state regulations and laws governing gasoline inspection and gasoline grading should it become impossible for gasoline distributors and dealers to comply therewith by reason of regulations or directives of the United States government or any of its departments or agencies, promulgated or issued as necessary to the war effort, and in order to insure the best grades of gasoline possible to civilian users and to facilitate motor vehicle traffic during any war in which the United States is now or may hereafter be engaged.

Any modifications or alterations of such requirements shall be issued in writing by the comptroller, with the written approval of the governor and the attorney general of the State of Mississippi, only upon receipt of official government directives, in conflict with existing statutes, and such official government directives shall be preserved and recorded in the office of the comptroller. Provided, however, that no adjustment shall be made which cannot be justified by proper government directives.

The enforcement of the provisions of all laws or parts of laws which are now or may become impossible to comply with by reason of such federal regulations or directives shall be suspended for such time as the impossibility of compliance therewith continues.

The power hereby conferred shall lapse and terminate at the end of six (6) months following cessation of hostilities.
