What would you do in this situation to prove your innocence.?

You're a lawyer/ politician and you wrote and contract for major league baseball player. When running for office you began to use things in his contract such as places where he'd be and how much he made to help you gain political popularity. The baseball player fires you and because of his popularity you began to lose some of your other clients. You decide to sue the baseball player for a monetary settlement and for causing you to lost the lifestyle you were once accustom too. On the court day the baseball player and his team decide to counter sue you for given out private information about his contract. You have lots of famous clients, one who is in the NFL has not fired you and he testifies for you in court saying that you have never given out any information about his contract to anybody. Also at the signing of the contract you had 1 or more people there as witnesses which the court finds illegal. How do you prove your innocence.
