3:22-3.  Exclusiveness of Remedy; Not Substitute for Appeal or Motion  
 Except as otherwise required by the Constitution of New Jersey, a petition 
pursuant to this rule is the exclusive means of challenging a judgment rendered upon 
conviction of a crime.  It is not, however, a substitute for appeal from conviction or for 
motion incident to the proceedings in the trial court, and may not be filed while such 
appellate review or motion is [available] pending.
