At a previous meeting, I and another Councillor were advised that we could not attend an 'in camera' meeting called by the Chair for immediately after the business meeting we were attending. No reason was given, and despite my questioning, we decided to leave as requested. We were never informed of any detail of the 'in camera' meeting, but both received a letter 2 weeks later, mine stating that "concerns had been raised about me posting on social media..... and reminding me not to post on social media, even though you [I] are trying to be helpful". This refers to me advising Parish residents of the dates of forthcoming meetings on FaceBook. I assumed that this was the subject (relevant to me) of the 'in camera' meeting that I wasn't allowed to attend, but this has never been confirmed.
Having discussed the matter with the other excluded Councillor, it appears that their 'charge' was that they were subject of an "outburst" at an earlier meeting and "used foul language"; they were explicitly asked to make an apology "in private at the end of the next meeting". However, on opening the next meeting the Chair said to the Councillor "Before we start the meeting, Councillor 'X' has something to say" [or words to that effect]; this caught the Councillor off guard and they responded with "No, I don't think so". It was at this point that the chair said "In that case, I would ask you to leave the meeting"; the Councillor left.
I and another Councillor questioned this, only to be told by the Chair that "we were not allowed to know the detail as it was confidential" [or words to that effect].
My primary question is: Can the Chair treat a Councillor in this way and banish them from a meeting before it even starts? Even if the process and outcome of the 'in camera' meeting was correct (in my view, it wasn't and their approach to dealing with our 2 issues was carried out in the form of a 'Kangaroo court' as neither of us were advised of the 'charge' and offered the chance to give our side), the ask on my fellow Councillor was explicitly requested to be done in private after the next meeting, but they were thrown out of said meeting before it even started.
Secondly, I suspect at the next meeting, we will be faced with the exact same situation, and if this happens, am I within my rights to raise a 'Point of Order' with the Chair?
Thanks in advance of any support/advice
