In Virginia, it is vital that the judge presiding over a criminal trial be as neutral as possible about the case before him or her. A bias in favor of the prosecution or the defendant may cause the judge to rule on an important matter, such as whether to admit a key piece of evidence, without properly following the law. The possibility of a conflict of interest, such as a personal relationship with someone connected with the case, is taken so seriously that most judges will withdraw from a case if even a hint of a potential conflict arises.
