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?
