``I am so delighted that I knocked on Tung's tiger head,'' Lo enthused at a press conference, referring to Chief Executive Tung Chee-hwa. ``I am confident I can block the listing. I have yet to decide over the appeal to the Court of Final Appeal because I still have to consult my lawyers and discuss the case with my neighbours.''

Giving a clue to what may be her motive for the case against the Housing Authority, the 67-year-old welfare recipient and public housing tenant said she has been involved in a concern group over public rental policy for some time and had battled the government over public housing rent increases.

Lo has become a local celebrity after delaying and disrupting the largest Reit listing in the world, confounding bankers, government leaders and investors.

Lo dismissed the charge that her case was being masterminded by politicians, particularly maverick lawmaker Albert Cheng, who paid her initial legal costs and has been vocal in his support.

``My heart is thinking of an appeal but this is a big event, not a triviality and it is not something I can decide by myself,'' she said. ``I will wait until my lawyers inform me. How dare anyone ask me to quit from an appeal?''

Lo was escorted by other elderly tenants and social workers to her first press conference since the application for judicial review.

Her co-applicant, Ma Ki-chiu, is ill and was not present.

Lo reiterated her opposition to the privatisation of shopping malls and car parks under the Housing Authority.

``If they sell our assets on the cheap, they will just hold our neck tight and we cannot breathe. We take action to defend our lives and Tung deters us by all means,'' she said.

Lo, who lives alone in a tiny flat and has no family, said the litigation had not changed her life.

`` I just continue my normal shopping and chatting with friends. As for whether this will ruin Hong Kong's reputation as an international financial centre, I had better say less rather than put it wrongly.''
