Petitioner pleaded guilty to three of seven counts charging violation of the Wagering Tax Laws, 26 Ú.S.C. § 7201
et seq.,
in August 1964, a time when assertion of his Fifth Amendment privilege against self-incrimination would not have barred conviction under these provisions.
Lewis
v.
United States,
1955,
The government does not dispute the retroactive effect of
Marehetti
and
Gros-so,
nor that, in the light of
United States Coin & Currency,
petitioner might compel vacating his conviction had he asserted his Fifth Amendment claim as either a precursor or an alternative to his plea of guilty. Rather, it makes the narrow point that a simple plea of guilty without the assertion of the privilege against self-incrimination constitutes a valid waiver of that privilege absent evidence that petitioner was “incompetently advised.”
See Brady
v.
United States,
1970,
The Court has placed a very heavy burden on one alleging incompetent advice, declining to find it even where both the defendant and his counsel were unaware at the time the plea was entered of substantial material facts or defenses. Thus it is insufficient to show that the defendant did not know a pretrial confession would be inadmissible,
McMann,
ante, or that his grand jury had been unconstitutionally constituted,
Toilett
v.
Henderson,
1973,
We see, however, one exception. Perhaps on the analogy of lack of consideration for a contract, if, because of an unknown constitutional right a defendant pleading guilty could not, in fact, have been prosecuted at all, and hence received an empty bargain, there is no reason to treat him any differently from a Marehetti or Grosso who sought no bargain, but went to trial. Thus, the Court has permitted a defendant to withdraw a plea founded upon a constitutional defect that goes to the very power of the sovereign to prosecute.
Blackledge
v.
Perry,
1974,
The government seeks to distinguish
Blackledge
on the ground that the defendant there could not have been prosecuted, “haled into court at all,”
In reaching this decision we do not rely on earlier cases such as
United States
v.
Miller, 4
Cir., 1969,
The order of the district court is vacated; the sentence and judgment of conviction are vacated; the indictment is dismissed, and the government is ordered to repay that portion of the fine which it has received 1 , without interest.
