1. A petition may be dismissed if delay in the filing of the petition:
(a) Prejudices the respondent or the State of Nevada in responding to the petition, unless the petitioner shows that the petition is based upon grounds of which the petitioner could not have had knowledge by the exercise of reasonable diligence before the circumstances prejudicial to the State occurred; or
(b) Prejudices the State of Nevada in its ability to conduct a retrial of the petitioner, unless the petitioner demonstrates that a fundamental miscarriage of justice has occurred in the proceedings resulting in the judgment of conviction.
2. A period exceeding 5 years between the filing of a judgment of conviction, an order imposing a sentence of imprisonment or a decision on direct appeal of a judgment of conviction and the filing of a petition challenging the validity of a judgment of conviction creates a rebuttable presumption of prejudice to the State. In a motion to dismiss the petition based on that prejudice, the respondent or the State of Nevada must specifically plead laches. The petitioner must be given an opportunity to respond to the allegations in the pleading before a ruling on the motion is made.
