Taiwan's opposition KMT and TPP are pushing a referendum law change that would put several questions on a single ballot, and local election officials say they are not ready for it.

• The change would force multiple referendum questions onto one ballot once a certain number is reached.
• Nantou County's election commission says the rules on what counts as a valid or spoiled vote would change, leaving no time to retrain poll workers.
• Staffing is already thin ahead of the year-end local elections, and officials fear workers will refuse to take part.
• There is also little time to teach voters how to fill out the new ballot, raising the risk of confusion on election day.

Outlook: The opposition bloc aims to pass the change in the legislature on Friday, setting up a clash with election administrators over whether it can be carried out in time.
