“Kovach was represented by an experienced attorney who carefully and independently vetted Kovach’s allegations and claims before determining she had a viable cause of action against respondents,” the court said in its per curiam opinion Wednesday. “Although Rule 11 allows for the possibility of sanctions against a client, it primarily speaks in terms of an attorney’s professional responsibilities. Rule 11 is not intended to be used as a weapon against a client represented by counsel, whose job it is to be knowledgeable of the law and advise a lay client on the best course of action.”
