As with oral examination at trial, depositions can become heated at times, with some attorneys asking harassing questions to provoke witnesses into losing their tempers, some witnesses giving evasive answers, and occasional use of profane language. In extreme situations, one side or the other may ask the reporter to mark the record, then may suspend the deposition, demand a rush transcript, and file an emergency motion to compel a response, for a protective order, or for sanctions. Some courts have magistrates or discovery commissioners who are on call for such contingencies, and the parties are supposed to use them to referee such disputes over the telephone or via email before resorting to filing motions. In extreme circumstances where the relationship between the lawyers, parties, or witnesses has totally broken down, the court may require the use of a discovery referee who will have authority to sit in on depositions and rule immediately on objections as they are presented, may order that all further depositions take place in court in the presence of a judge, or may grant terminating sanctions if the record is already clear as to which party or attorney is responsible for the breakdown in civility.
