A parish councillor was censured after he accused other councillors of corruption and branded a member of the public "a geriatric".
John Copeland has now left his seat on Burton Parish Council, saying he can no longer stand the "nonsense" of meetings.
On May 23, West Lindsey District Council's standards committee sanctioned Mr Copeland on two counts of breaching the parish council's code of conduct.
The committee declared he had failed to treat others with respect and had brought the officer of the councillor/the authority into disrepute.
The ruling came after Mr Copeland spoke out in a public meeting in October 2011.
During a debate, he made a personal attack on members of West Lindsey District Council's planning authority when he made comments about "bribes and corruption".
The standards committee also heard how Mr Copeland sent an email about a bus stop in Burton Waters in which he called a member of the public "a grumbler and a geriatric".
The report stated: "The Standards Committee reached the decision after considering the written evidence, particularly the mitigating comments made by former Councillor Copeland contained within the Investigating Officer's report and having taken into account the guidelines."
Mr Copeland stepped down from the council in 2011.
However, Mr Copeland has stressed his decision was not due to the hearing.
"I was chairman of the Burton Parish Council for 10 years and I didn't have any trouble. I came back in May last year and everything has changed, it is terrible," he said.
"I was elected unopposed and only managed one and a half sessions. I couldn't stand the nonsense.
"Meetings were going on for three hours.
"My decision to leave was not related to the hearing. I'm 78, and someone younger could take my place."
