The Supreme Court has said that secrecy is not congenial to truth seeking. No better instrument has been devised for arriving at the truth than to give a person in jeopardy every serious notice of the case against him and an opportunity to meet him. That was in the Joint AntiFascist Refugee Committee versus McGrath. 1951. The court also said: Certain principles have remained relatively immutable in our jurisprudence. One of these is that where the Government action seriously injures an individual and the reasonableness of the action depends on factfinding. the evidence used to prove the Governments case must be disclosed to the individual so that he has an opportunity to show that it Is untrue.
