Improper appeal to CA; dismissal

Section 2, Rule 50 of the Rules of Court reads:
Sec. 2. Dismissal of improper appeal to the Court of Appeals. – An appeal under Rule 41 taken from the Regional Trial Court to the Court of Appeals raising only questions of law shall be dismissed, issues purely of law not being reviewable by said court. Similarly, an appeal by notice of appeal instead of by petition for review from the appellate judgment of a Regional Trial Court shall be dismissed.

An appeal erroneously taken to the Court of Appeals shall not be transferred to the appropriate court but shall be dismissed outright. (Emphasis and underscoring supplied)
