Such notice shall include a certification by the trial counsel that the appeal is not taken for the purpose of delay and, if the order or ruling appealed is one which excludes evidence, that the evidence excluded is substantial proof of a fact material in the proceeding.(d) Diligent prosecution required.--An appeal under this section shall be diligently prosecuted.

In ruling on an appeal under this section, the court may act only with respect to matters of law.Added by P.L. 1506 2012 No. 192, § 2, eff. 10/24/2013.
