Before the case of Commonwealth v. Koch was even appealed to the state Supreme Court, attorneys were calling it Pennsylvania’s landmark case on the admissibility of electronic communications.

Today, attorneys for the state will argue the state Superior Court erred when it ruled there was no evidence showing a Pennsylvania woman wrote the drug-related text messages police found on her cellphone in 2009. The justices’ decision on the matter, according to courtwatchers, could be the governing literature on whether attorneys may submit text messages found on a person’s cellphone as, well, theirs.
