conviction or sentence.

Any person who has been convicted of, or sentenced for, a crime

and who claims:

1. That the conviction or the sentence was in violation of the

Constitution of the United States or the Constitution or laws of

this state;

2. That the court was without jurisdiction to impose sentence;

3. That the sentence exceeds the maximum authorized by law;

4. That there exists evidence of material facts, not previously

presented and heard, that requires vacation of the conviction or

sentence in the interest of justice;

5. That the sentence has expired, the suspended sentence,

probation, parole, or conditional release unlawfully revoked, or he

or she is otherwise unlawfully held in custody or other restraint;

or

6. That the conviction or sentence is otherwise subject to

collateral attack upon any ground of alleged error heretofore

available under any common law, statutory or other writ, motion,

may institute a proceeding under the Post-Conviction Procedure Act

in the court in which the judgment and sentence on conviction was

imposed to secure the appropriate relief. Excluding a timely

appeal, the Post-Conviction Procedure Act encompasses and replaces

all common law and statutory methods of challenging a conviction or
