As DtC states, minutes are a record of the decisions made. If the resident wanted to formally complain about the council, they would need to do so via the complaints policy. They could also record the meeting if they wished in order to support their complaint.
What is interesting is confusion about the involvement of the public in council meetings. These meetings are not public meetings but meetings in public and they are invited to speak rather than having a right to speak. So they need to follow the complaints procedure when criticising the actions of the council.
