Mr. Dave Walsh:

When we communicate with people who make an observation, we need their contact details, name and address. We send correspondence back to them to acknowledge it. If the correspondence is returned, it is a sign that it may be the wrong address or that there may be another issue. We would pursue it. We often send three or four letters as reminders, sometimes in registered post. If there are no responses and nothing can be delivered, we have to make a call about whether that is a valid observation. That is the normal practice generally. In the case the Deputy is referring to, without going into details, that was not the only observation on that particular case.
