The state constitution does not provide for the level of evidence required to determine whether such conduct is impeachable, or the number of votes required to convict, unlike the U.S. Constitution. The Senate conducted a three-week trial and ultimately acquitted Brock of all charges, finding the charges were not serious enough to warrant impeachment or that the evidence presented at trial was not persuasive. The Senate chose to require a two-thirds vote to convict, but let each senator to decide for themselves if the evidence rose to the level of finding Brock was "guilty" of the articles of impeachment. Fifteen senators were needed for a conviction, only seven voted to convict and fifteen voted to acquit.
