Regional Transp. Comm'n. of S. Nev. v. Wang

 immediately appealable. The motion is opposed. Having considered the
motion and the arguments of counsel, and cause appearing, we deny the
motion to confirm jurisdiction.
This court has declined to adopt the collateral order doctrine:
Interlocutory appeals cause delay, expense and
disruption. Adopting the collateral order doctrine
would require this court to extensively screen
appeals from interlocutory orders to determine
whether this court has jurisdiction. Jurisdiction
lines would become unfocused and uncertain. This
in turn could result in a proliferation of premature
appeals. These burdens would outweigh any
possible benefits that could result from adoption of
the collateral order doctrine.

(1993) (internal citations omitted). Instead, this court addresses
challenges to a district court's preliminary rejection of a claim of
governmental immunity through its powers to grant extraordinary relief.
See, e.g., State v. Second Judicial Dist. Court ex rd. Cnty. of Washoe, 118
Nev. 609, 617, 55 P.3d 420, 425 (2002).
This court has jurisdiction to consider an appeal only when the
appeal is authorized by statute or court rule. Taylor Constr. Co. v. Hilton
