PHILADELPHIA – A federal judge has refused to dismiss a defamation suit brought by two law professors who claim that West Publishing harmed their reputations when it falsely identified them as the authors of a poorly researched treatise update.

In the suit, professors David Rudovsky of the University of Pennsylvania Law School and Leonard Sosnov of Widener Law School claim that they did none of the work on the December 2008 supplement, or “pocket part,” to their book, “Pennsylvania Criminal Procedure: Law, Commentary and Forms.”
