Our Council places all documents that will be discussed, as per the agenda, online, unless they are exempt documents under normal the Public and Media exclusion rules.
As all documents are 'theoretically' working documents, then there is no excuse for not publishing, but adding the caveat that what is published with the agenda, 'may' be different from what is finally presented.
The other thing that 'occasionally' occurs with us, it that we notify they will include xxxx item on the agenda, and the public version will be available on the night, but that is rare.
However, they never hide financial documents, ever...
That is how 'our mob' do it and that has been accepted for a few years now!
