I am showing my naivety here. I am aware that the regulations are reviewed on an ongoing basis. Are the witnesses pulled into that? Do they know when the regulations are reviewed? How many reviews have taken place in the last 20 years? There has to be somebody saying "No" to these changes. Is the review just done behind a closed door and then the regulations are what they are?
