Mr Sills had already dismissed a complaint that he had breached health and safety legislation by drinking the water to prove it was clear of 1080, while other recommendations, including that the council remind him in writing that he needed to separate his personal and council opinions, were rejected, on the basis that if such a letter was required it should go to all elected members.
CEO Malcolm Nicolson said council policy allowed representatives to express personal opinions as long as they make it clear that those opinions were not the council's. He also noted Cr Finlayson had articulated a personal view because the council did not have 1080 policy, which was his fault.
To the obvious dismay of the complainants, who were in the public gallery, the council then agreed to develop a policy.
Cr Finlayson said the complaints process had been stressful.
"Drinking that water was a response to a challenge that came from anti-1080 people," he said.
"I knew the water testing had come back clear, and I wanted to show that the narrative that 1080 poisons water is a false narrative. I'd also like to make the point that I never personally attacked people, but I have been personally attacked, and called a liar, among other things."
Meanwhile council chairman Bill Shepherd declined a request from one of the complainants to speak, prompting the claim that they had been denied acknowledgement and respect, despite Mr Sills' finding that Cr Finlayson had breached four sections of the code of conduct.
"Naturally we are disappointed that the NRC have essentially ignored the findings and recommendations, thus demonstrating a real lack of accountability," she said.
"While Cr Finlayson was allowed to write a lengthy rebuttal to the investigator's report, and allowed to speak at the meeting before the deliberation, (we) were not given any such opportunity to respond to the report. It created a climate of bias and left us feeling frustrated, unheard and disrespected."
