cases for the recovery of fees, penalties, etc.; of questions
regarding the validity of ordinances and by-laws of a corporation;
or involving the right to levy taxes; and all cases civil or
criminal when an appeal may be had to the Supreme Court of
Appeals. Also, of all proceedings by quo warranto; and may issue
writs of habeas corpus, mandamus, prohibition, and certiorari to
all inferior tribunals; issue writs of mandamus in all matters
arising from or appertaining to the action of the board of
supervisors; determines the probate of wills and testamentary
cases; may appoint guardians, curators, commissioners in chancery,
etc.

Appellate jurisdiction of all cases, civil and criminal, where an
appeal writ of error or supersedeas may be taken or allowed by
said courts from or to the judgment or proceedings of an inferior
tribunal. But no circuit court shall have any original or
appellate jurisdiction in criminal cases arising within the
territorial limits of any city wherein there is established by law
a corporation or hustings court.

Original jurisdiction means jurisdiction from the beginning of a
case--that is, power to take up and try it when it is first
entered in law. The Supreme Court of Appeals has not this power.
It can deal only with cases that have already been tried in some
other court. But the circuit courts may try cases on their first
hearing. This is original jurisdiction. They have also general
jurisdiction--that is, they can try all cases in general in which
the law is violated, or the protection of the law is sought or
required.
