If the State Department of Motor Vehicles suspects a driver of violating a motor vehicle law, they must hold a hearing to decide if the driver's license should be suspended or revoked. The driver can appeal this decision to a state district court. Irene receives a notice on August 25 stating she must attend a hearing on September 25 to determine if her license will be suspended or revoked for allegedly driving under the influence on August 2. At the hearing, Irene asks to call her husband and employer to testify that she was in Europe during the alleged incident, but the hearing officer denies her request, saying she had time to prepare. After the hearing, the officer suspends her license for 90 days, stating that she can appeal the decision. What burden of proof do you believe should be applied to agency actions that encroach on civil liberties? Sources cited
