In November of 2010 an Independent Medical Examiner for the Veterans Admininstration made numerous erroneous statements in my files. He had medical documents available to him that stated just the opposite of his entries but chose to ignor them. He answered questions with negative answers without asking me those questions so I could respond. Now his negative and erroneous entries have caused a disability rating to be one half of what it would have been if he had been truthful. What is the statute of limitations for filing a Tort claim or lawsuit against him?.
