The use of discovery has been criticized as favoring the wealthier side in a lawsuit, by enabling parties to drain each other's financial resources in a war of attrition. For example, one can make information requests that are potentially expensive and time-consuming for the other side to fulfill; respond to a discovery request with thousands of documents of questionable relevance to the case; file requests for protective orders to prevent the deposition of key witnesses; and take other measures that increase the difficulty and cost of discovery. In 1983, the Advisory Committee on Civil Rules attached a Committee Note to Rule 26 of the FRCP that cautioned federal courts to "prevent use of discovery to wage a war of attrition or as a device to coerce a party, whether financially weak or affluent," then had to repeat and stress that exact same text in the 2015 Committee Note.
