Judgment unanimously affirmed. Memorandum: In this article 78 proceeding petitioner-appellant contends that his present detention is invalid and is violative of his constitutional right to procedural due process. Petitioner was convicted in this State in 1957 of the crime of robbery and was sentenced to 15 to 30 years.

We agree with that position (Matter of
