for a writ of habeas corpus is the exclusive remedy to challenge the

validity of a guilty plea after sentencing. The State argued that construing the motion as a post-conviction petition for a writ of habeas corpus, the motion was procedurally barred as it was filed almost nine years after entry of the judgment of conviction. 

### See NRS 34.726(1). The district court determined that appellant was not challenging the validity of his judgment of conviction and sentence, but was challenging the computation of time served and denied the motion without prejudice for him to file a post-conviction petition for a writ of habeas corpus.

To the extent that appellant raised a claim challenging an alleged breach of the plea agreement, the motion was untimely filed and appellant failed to demonstrate good cause to excuse his procedural defects. 2 

### See id. However, to the extent that appellant challenged the computation of time served, the district court correctly determined that this claim must be raised in a post-conviction petition for a writ of habeas
corpus, 

### see NRS 34.724(2)(c), and could not be raised in a petition that also challenged the validity of the judgment of conviction and sentence, 

### see NRS 34.738(3). Accordingly, we conclude that the motion was properly denied in this case. 3

2 Appellant argued that he had good cause because he just learned that the Department was incorrectly structuring his sentence. However, this does not provide good cause as the breach claim was reasonably available to be raised in a timely petition as the sentences were structured in 2005. The fact that appellant only thought to ask about his sentence structure in April 2014, does not provide good cause for the delay in this
case.

3 We conclude that the district court did not abuse its discretion in denying the motion to appoint counsel.

### Saitta J.

Motion to Modify Sentence

In his motion filed on June 18, 2014, appellant argued that his sentence should be reduced because of mental health issues and his amenability to future treatment and because he received ineffective assistance of counsel. Appellant's claims fell outside the narrow scope of claims permissible in a motion to modify sentence. See Edwards v. State, 112 Nev. 704, 708, 918 P.2d 321, 324 (1996). Therefore, without considering the merits of any of the claims raised in the motion, we conclude that the district court did not err in denying the motion. Accordingly, we

ORDER the judgment of the district court AFFIRMED. 4
