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.
For the second time appellant is here seeking relief under 28 U.S.C. § 2255 from a sentence imposed under 18 U.S.C. § 2113. The trial court, without a hearing, denied relief. On his prior application appellant contended that his guilty plea was not made voluntarily and understanding^. The trial court held to the contrary and we affirmed. Bailey v. United States, 10 Cir., 312 F.2d 679.
Appellant now contends that the sentence should be vacated because the prosecution followed an illegal arrest and search. We have held to the contrary in a case brought by a codefendant. See Sullivan v. United States, 10 Cir., 315 F.2d 304.
Appellant says that the present application should not have been denied without a hearing. The contention is without merit. As we pointed out in Sullivan, if the guilty plea was voluntary, the allegedly illegal conduct is no ground for relief under § 2255. In the prior § 2255 application we held that the guilty plea was made knowingly and voluntarily.
Affirmed.
