http://legal-dictionary.thefreedictionary.com/referee

A judicial officer who presides over civil hearings but usually does not have the authority or power to render judgment.
Referees are usually appointed by a judge in the district in which the judge presides. Referees aid the judge by hearing certain matters and by making recommendations concerning special or complicated issues. Judges generally delegate a portion of their judicial power to referees, who then report their recommendations to the judge concerning the issue.
In most jurisdictions a referee must be an attorney. Nevertheless, in some complex property or financial matters, a judge may appoint a person who is not an attorney to preside over a dispute and to make recommendations.
