Taiwan's opposition parties are pushing a referendum law change that election staff say could throw voting into disorder — bad news for local election offices already short on people.

• The KMT and TPP plan to pass a change on Friday that would print several referendum questions on a single ballot.
• Nantou's election commission says the new system is being rushed and local offices cannot handle it in time.
• The rules for what counts as a valid or spoiled vote would change, and there is not enough time to retrain staff or explain the new marking method to voters.
• Year-end local elections are already complicated and badly understaffed, and the change could push more workers to quit or refuse the job.

Outlook: If the bill passes Friday as planned, election offices face a scramble to rewrite procedures and recruit staff before the year-end vote.
