Raymond Case v. State Minnesota

We adhere to our holding in State v. Knaffla, 309 Minn. 246, 243 N.W.2d 737 (1976), that where a direct appeal has once been taken in a criminal case, all matters raised therein and all claims known but not raised will not be considered upon a subsequent petition for post-conviction relief. Only where a claim is so novel that it can be said that its legal basis was not reasonably available to counsel at the time of direct appeal should post-conviction relief be allowed.
