''I can confirm that complaints - plural - have been received.''
The complaints came after Cr Vandervis allegedly shouted and swore at Dr Bidrose on Monday last week, during an angry tirade in a Municipal Chambers hallway.
Cr Vandervis was understood to be upset at the process surrounding an earlier complaint against him.
He initially downplayed the incident, but later conceded his outburst may have been louder than he first thought, and it was also ''possible, but ... incredibly unlikely'' he swore at Dr Bidrose.
Mr Cull said yesterday he would assess the complaints before reporting to the next full council meeting on February 23 on whether there were reasonable grounds to believe a breach might have occurred.
If there was, a conduct committee would be formed to handle the complaints, although its make-up was yet to be decided, Mr Cull said.
He had already recused himself from taking a place on the committee, and one option could have a single independent representative appointed with the agreement of all parties, he said.
The timeline to resolve the complaints was not yet known.
