Political Problems Facing Governments in Using Scientific Advice, and   Legal and Other Problems Facing Scientists when Trying to Give Independent   Advice to Governments
  It is the role of the scientific community to provide for the knowledge of scientific facts and technical capabilities as a background for political decision-making. The reasons are given why governments are sometimes not ready to accept well-founded advice. The legal relationship between governments and scientific research are considered. The options available to the scientific community for supplying useful advice to decision-makers and to the public in questions of general concern are delineated.
