UPDATE: Perth Lord Mayor Lisa Scaffidi has indicated she plans to resume her mayoral duties after winning an appeal against an 18 month disqualification for failing to disclose gifts and travel.

Ms Scaffidi said she would make a decision “as to when to return to my duties as Lord Mayor” once she had an indication when the State Administrative Tribunal will meet to determine a new penalty for failing to disclose gifts and travel.

WA’s Court of Appeal on Friday dismissed 26 of the 45 breaches of the Local Government Act Ms Scaffidi was previously found to have made. All of the breaches Ms Scaffidi challenged were thrown out by the court, leaving 19 unchallenged.

The State will pay all of Ms Scaffidi’s costs for the successful breaches appeal and half the costs for her penalty appeal.

The SAT will now decide just what penalty Ms Scaffidi will face for the 19 confirmed breaches of the Act, with the previous 18-month disqualification having been set aside. A date for that to happen has not yet been set.

In a statement tweeted late Friday morning Ms Scaffidi said she was disappointed the question of a penalty would be left to the SAT to decide. She previously gave an undertaking to stand aside from her mayoral duties pending the outcome of the appeal.

“As to where to from here, my legal team have written an open letter to the State Solicitor’s Office inviting discussions with a view to agreeing a penalty and thus bringing about a final resolution to this matter as soon as possible,” she said.

“Disappointingly the State Solicitor’s Office has responded that the Department ‘considers it appropriate that the question of penalty be left to the Tribunal to determine, and accordingly declines to enter into negotiations to attempt to reach an agreed position.’

“My offer to the Department to have discussions and endeavour to bring about a final resolution as soon as possible, remains open. I hope the Department will reconsider its position as it would seem to be in everyone’s best interests that this matter be resolved as soon as possible.”

Ms Scaffidi was not in court to hear the verdict, which was a significant win for her.

Ms Scaffidi’s problems began in 2015 when she was caught up in an international probe into BHP Billiton's entertainment of dignitaries at the 2008 Olympics.

That probe triggered a Corruption and Crime Commission investigation and ultimately lead to a State Administrative Tribunal hearing earlier this year.

In May the SAT found Ms Scaffidi had breached the Local Government Act 45 times and disqualified her from holding office for 18 months.

Ms Scaffidi appealed both a number of the breaches and the penalty, which is believed to be the harshest imposed on a sitting councillor in Australia.

In November the Court of Appeal opted to reserve its decision on the long-running saga.

Ms Scaffidi accepted a number of trips paid for by third parties, including a trip to the Beijing Olympics paid for by BHP, trips to visit the City of Perth's sister cities and trips as part of her role with the Australian Press Council.

At the appeal hearing Ms Scaffidi’s lawyer Steven Penglis argued trips to Perth’s sister cities were not gifts because if the cities had not covered the cost, Perth would have.

Mr Penglis argued accommodation paid for by the APC did not constitute a gift but was a legal obligation.

State Counsel George Tannin argued the sister city trips constituted a gift, regardless of the prospect of reimbursement.

Mr Tannin said gifts could be given in the context of a legal obligation but that did not absolve the recipient from declaring them.

Ms Scaffidi's level of remorse was also raised as an issue at her appeal.

Ms Scaffidi’s disqualification has been on hold pending the outcome of the appeal. Councillor Jemma Green is the Acting Lord Mayor.
