The problem was that the timing is crucial for the new chief executive election after Tung Chee Hwa's resignation on 12 March 2005. Since electoral law states that an election must be held 120 days after the vacancy, an election would be held on the tenth of July. It was unclear as to the exact time period separating the election and the date of taking of office for this Election Committee. If the new EC convened prior to the chief executive election, it would be applied to select the next chief executive, but otherwise the old Election Committee dating from 2000 would have to complete the task (see 2005 Hong Kong Chief Executive election for more information on the topic). The second round produces a further dispute, if the term of the old EC ended after the first round of voting but before the second. It would be rather insensible to use different electors for the two rounds; the same one would probably have to be prescribed.
