"When a court recalls a felony sentence and imposes a misdemeanor
sentence pursuant to Penal Code section 1170.18, subdivision (a) (Proposition 47), may
the court revisit the sentence imposed on other misdemeanor counts, not subject to
Proposition 47, and impose a harsher punishment? Yes, provided that the new aggregate
sentence does not exceed the prior sentence."
Yep. That's exactly what the opinion says.
Love it when the first paragraph of the opinion tells you pretty much everything you need to know.
(Except for the reasoning, of course. Which sometimes I agree with, and sometimes not.)
