A Sixth-Amendment claim grounded on such a credible allegation, even if unartfully worded in a pro se motion, must be explored at a hearing which gives a defendant an adequate opportunity to shoulder his burden of showing the inadequacy of his counsel. See Venable v. Neil, 463 F.2d 1167 (6th Cir.), cert. denied, 409 U.S. 1079, 93 S.Ct. 677, 34 L.Ed.2d 669 (1972); Goodwin v. Cardwell, 432 F.2d 521 (6th Cir. 1970). In the event that upon remand a determination is made that the appellant did not receive effective assistance of counsel in making his guilty plea and a withdrawal of that plea is permitted, then his waiver of his rights under IAD because of that plea must also be invalid.
This Court will, however, vacate the district court's order and remand for an evidentiary hearing because we cannot conclusively determine the accuracy of petitioner's allegations of failure of his trial counsel to confer with him or to prepare and investigate adequately possible defenses prior to trial. Gaines v. Hopper, 575 F.2d 1147, 1149 (5th Cir. 1978); Venable v. Neil, 463 F.2d 1167, 1168 (5th Cir. 1972); see also note, 93 Harv. L.Rev. 752 (1980). The record establishes that petitioner Clark has exhausted his state remedies on the issues of his counsel's failure to confer with him and his counsel's failure to prepare adequately prior to trial.
