HC Deb 09 November 1979 vol 973 c348W
Mr. Rooker

asked the Secretary of State for Energy if he will list those topics on which it is not his practice to answer parliamentary questions; and if he will list any changes in the practice of his Department since 3 May.

Mr. David Howell

It is not possible to provide a definitive and exhaustive list of questions which I might exceptionally decline to answer on grounds other than cost. Each question will continue to be considered on its merits but, by way of illustration, I would decline to answer where confidential, commercial, or security information arises; and on matters which are the responsibility of public bodies.
