In Cabot Oil and Gas Corp. and Gassearch Drilling Serv., an interlocutory appeal from a discovery dispute, the PA Superior Court held that an appeal from a collateral order under Pa.R.A.P. 313 is timely when it is taken more than 30 days from entry of the order so long as the appeal is perfected when the collateral issue is finally determined. Second, the Court held that the lower court properly compelled the defendants to disclose their tax returns for “attorneys’ eyes only” as punitive-damages discovery.
