Review under this chapter shall be obtained by filing a petition for review with the prothonotary of the appellate court within the time allowed by Pa.R.A.P. 1512. Failure of a petitioner for review to take any step other than the timely filing of a petition for review does not affect the validity of the review proceeding, but is grounds only for such action as the appellate court deems appropriate, which may include dismissal of the review proceeding.
