Former Ipswich deputy mayor Paul Tully claims he did not know about the alleged behaviour of two previous mayors on the Ipswich City Council, saying to the ABC there was no way for him to know about their private activities.

He says as he did not have the power to compel people to give evidence, interview people or tap phones, it is not clear how he could be responsible for behaviour in the private lives of others.

These comments come as the Ipswich City Council takes the state government to the supreme court in an effort to stop the council being put on notice.
