The state Superior Court has reversed an Allegheny County trial court’s judgment of non pros in a professional negligence case against a Carnegie, Pa.-based law firm.

The case is what is known as a “straddle case,” in which a praecipe for writ of summons was filed before Pennsylvania Rule of Civil Procedure 1042.3, which requires a certificate of merit to be filed within 60 days of a complaint in a professional negligence case, was promulgated but the complaint wasn’t filed until after the rule became effective.
