(2) Upon the granting of a motion for a new trial on the ground of newly discovered or newly available evidence but only on questions of law.
(3) When the State alleges that the sentence imposed:

c. Contains a term of imprisonment that is for a duration not authorized by G.S. 15A-1340.17 or G.S. 15A-1340.23 for the defendant's class of offense and prior record or conviction level; or
d. Imposes an intermediate punishment pursuant to G.S. 15A-1340.13(g) based on findings of extraordinary mitigating circumstances that are not supported by evidence or are insufficient as a matter of law to support the dispositional deviation.
