Legal Question in Criminal Law in Massachusetts

There are no judges that I've heard of that sit on both appellate and trial courts. So, generally, that seems unlikely. And of course, should there be such a judge, there would be an obvious need to recuse him/herself (as Justice Sotomayor did when some of her prior decisions reached the Supreme Court).

However, if by 'appeal', you mean a motion to reconsider or for a new trial, then yes, the same judge would usually hear such an argument.

It must mean that the trial judge is now an appellate judge.

It depends on the result of the trial, and if it was jury or bench.

Usually, they will, if reminded, recuse themselves.

Call me with any questions.
