It's unreasonable to expect someone like a Cabinet Minister or the CEO of a Large organisation to know the detail of every memo / policy/ discussion that takes place. You have to delegate responsibility to people that have been given a brief and then need to create the systems / processes to actuate the policy. OK, as the head of department you are ultimately responsible but if the people down the chain fail to carry out policy outlined then they should be held to account.
..and if they do not carry out the policy for whatever reason? - then perhaps it is you as the CEO who must ultimately take responsibility for the existence of the environment or culture in which that has happened.
