I think it is a slightly verbose way of saying that any documents (including E mails) passed to the chair or Clerk) must dealt with in accordance with existing legislation that applies to said document.. So for example if the Clerk receives a FOI request, they must deal with in in accordance with the FOI Act 2000, and not hold on to it and do nothing. Or if an invoice for payment is received it should be presented fo payment authorisation rather then being stuffed in a drawer and ignored.
