I don't believe it will. A civil lawsuit is based on a preponderance of evidence, and is not based on the amount of evidence, per se, but which side is more convincing. And, because this is not a criminal trial, in which a case must be proven beyond a reasonable doubt, the standard for allowing the case to go forward is much easier. I would not be at all surprised if he settled this out of court. With the apparent lack of hard evidence, all it takes is his checkbook to make this go away. If he doesn't settle, this could become a long, and protracted battle, which could certainly become damaging to his career, regardless of how innocent he may, or may not be. JMO.
