I. Does Tollett v. Henderson, 411 U.S. 258 (1973), preclude the government and a defendant from conditioning a guilty plea on the defendant's right to collaterally attack the conviction on grounds other than ineffective assistance of counsel that renders the plea invalid?

II. If not, when a defendant conditions a guilty plea on the right to collaterally attack the conviction via "any subsequent claims with regards to ... prosecutorial misconduct," does this language only authorize collateral attacks based on post-plea prosecutorial misconduct?

III. When a defendant pleads guilty, does Tollett preclude the defendant from collaterally attacking the sentence because of surreptitious prosecutorial misconduct into confidential attorney-client communications that predated the guilty plea?

Does Tollett v. Henderson preclude a defendant from collaterally attacking a conviction based on pre-plea prosecutorial misconduct?
