Task: songer_casetyp1_1-3-1

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "criminal - federal offense". 

PER CURIAM.
This is an appeal in forma pauperis from a denial of a motion under 28 U.S.C. § 2255 to correct an allegedly illegal sentence. Appellant has served the sentence of three years imposed on him on his plea of guilty to Count I of a three count indictment charging the illegal transportation of aliens. 8 U.S.C.A. § 1324(a) (2). Appellant also pleaded guilty to Counts II and III, and was sentenced to two consecutive terms of two years each, to be served consecutively to the Count I sentence.
Each indictment of the transportation referred to one time, one auto, one origin, and one destination, but referred to three individual aliens. Appellant urges this can be but one offense.
The statute to which appellant entered his pleas, itself specifically provides that transportation of each alien shall constitute a separate offense.
The appropriate punishment for a particular federal offense is a matter subject only to the discretion of Congress, provided no constitutional limitation is violated. Bell v. United States, 1955, 349 U.S. 81, 75 S.Ct. 620, 99 L.Ed. 905. When Congress clearly defines the unit of prosecution, the courts cannot intervene, nor by “interpretation” change the law.
We have heretofore passed on this same appellant’s identical claim. We affirm what we have previously said, Vega-Murrillo v. United States, 9 Cir., 1957, 247 F.2d 735, and we affirm the district court herein.
