Background
Zion Justin Castillo pleaded guilty to robbery after he and another person entered a Metro PCS store, held an employee in a back room with a firearm, and took money from the register. The State dismissed other charges and agreed to make no sentencing recommendation. The sentencing judge imposed a suspended prison term of 24 to 60 months and probation for up to 36 months. Over the State’s objection, however, the judge added a “drop-down” provision that the parties had not negotiated: if Castillo successfully completed probation, he could withdraw the felony robbery plea and plead guilty instead to gross-misdemeanor conspiracy.
The case was later reassigned to another department. After Castillo established that he had satisfied his probation conditions, the successor judge granted him an honorable discharge but refused to enforce the drop-down. The judge concluded that the original provision was legally erroneous, denied Castillo’s request to withdraw his robbery plea, and amended the judgment to remove the provision. Castillo appealed, arguing that one district judge lacked jurisdiction to undo a ruling entered by another judge of equal authority.
The Court’s Holding
The Nevada Supreme Court unanimously affirmed. Justice Bell explained that a properly assigned successor judge’s power to revisit a predecessor’s decision is not a question of subject-matter jurisdiction. The court expressly overruled Rohlfing v. Second Judicial District Court to the extent that decision suggested otherwise. Rohlfing properly used jurisdictional reasoning when a judge who was no longer assigned to a case intervened in it, but later decisions had stretched its language into a broader rule against successor-judge reconsideration.
The controlling framework is instead the law-of-the-case doctrine, a judicial practice that protects consistency, finality, and institutional integrity without eliminating the court’s power to correct a ruling. Under the three exceptions adopted in Litchfield v. Tucson Ridge Homeowners Association, a successor judge may revisit an earlier decision when later proceedings produce substantially different evidence, controlling law changes, or the prior ruling was clearly erroneous and enforcing it would cause manifest injustice. Mere disagreement with the first judge is insufficient.
The third exception applied here. Charging decisions and plea negotiations belong almost exclusively to the executive branch. Unlike a legislatively authorized sentencing alternative, Castillo’s drop-down was created by the sentencing judge, was not part of the negotiated plea, and was imposed over the prosecutor’s objection. By allowing Castillo eventually to substitute gross-misdemeanor conspiracy for the charged felony, the provision invaded prosecutorial charging authority and violated Nevada’s constitutional separation of powers.
Enforcement also would produce manifest injustice. Although Castillo relied on the promise while completing probation, the court reasoned that forcing the State to accept a plea deal it never offered would override prosecutorial discretion, undermine the judiciary’s appearance of neutrality, and erode a foundational structural protection. The successor judge therefore acted within the law-of-the-case exception and did not abuse her discretion by deleting the provision while leaving the robbery conviction in place.
Key Takeaways
- A properly assigned successor district judge has jurisdiction to reconsider a predecessor judge’s ruling in the same case; law-of-the-case principles govern whether reconsideration is appropriate.
- Rohlfing is overruled insofar as it imposed a jurisdictional bar on successor-judge review, though its rule remains relevant when an unassigned judge attempts to intervene.
- Reconsideration requires substantially new evidence, an intervening change in controlling law, or a clearly erroneous ruling whose enforcement would cause manifest injustice.
- A sentencing judge cannot unilaterally create a post-probation plea reduction that substitutes a lesser charge over the State’s objection and lacks statutory authorization.
Why It Matters
Castillo resolves a recurring Nevada procedural problem created by reassignment, retirement, or election of a new judge. Litigants should no longer frame every effort to revisit a predecessor’s ruling as a jurisdictional defect. The practical fight will be over law of the case and its narrow exceptions, with appellate review asking first whether the doctrine applies and then whether the trial court abused its discretion. A motion should identify the specific exception and explain why ordinary finality interests yield; a successor judge’s different view of the law will not be enough.
The criminal-law holding also draws a firm line around creative sentencing. Nevada courts may select among sentencing options authorized by statute, but they may not use a judgment to renegotiate the offense after the prosecutor has exercised charging authority and the parties have completed their bargain. Defense counsel seeking a conviction drop-down should secure it through the plea agreement or identify express legislative authorization before sentencing. Prosecutors should make a clear contemporaneous objection when a court adds an unnegotiated charge reduction. For district judges, the decision separates permissible sentencing discretion from an executive function: reducing punishment within the authorized range is judicial, while replacing the offense of conviction without the State’s consent is not.
