Lawyers may not ethically repeat in a lawsuit an assertion of fraud, unless they have first assured themselves that there is a sound factual basis for such a serious charge. Core principles of professional ethics prohibit lawyers from becoming instruments in a campaign to use the courts to foment unfounded attacks on the integrity of the most basic institution of our democracy, the right of the people to select their leaders. Nor is it permissible to start a lawsuit propounding the client’s thesis, simply hoping that some support for the claim may turn up. The ABA Model Rules of Professional Conduct direct lawyers to refrain from bringing a proceeding “unless there is a basis in law or fact for doing so that is not frivolous.”
