If a person is sued by a company, but he has informed the company that he is not the person they think he is, and the company goes through with the lawsuit...(run-on sentence)
Then the person shows the judge that he isn't the person and the judge dismisses the case.
Can this person then countersue for court costs, lawyer fees and more compensation?
