But the six-day limitation may be ignored if the rally had to be held immediately due to some "unpredictable major emergency."
Some critics had panned Ma for deciding that the KMT's rally yesterday qualified as an "unpredictable major emergency."
Ma yesterday also assured protesters that he would not accept some party members' suggestion that he quit his position as Taipei mayor to focus on ousting Chen.
"I have an eight-year promise with Taipei residents and I don't plan to break the promise. Besides, I don't think it's necessary to resign," Ma said.
