Taiwan's opposition parties are forcing through a change to referendum rules that would print several questions on a single ballot, and the ruling party says it could break the vote count at the end of the year.

• The KMT and TPP want multiple referendum questions on one ballot paper and sent the bill straight to a second reading, skipping committee debate.
• The DPP caucus is urging them to back off, warning that "elections cannot be an experiment."
• The election commission says the change would sharply raise the number of spoiled ballots and push vote-counting staff past what they can handle.
• Counting could no longer be done question by question, making it harder for the public to watch the count.
• There is not enough time to prepare election staff before the year-end vote, raising the risk of mistakes.

Outlook: If the bill passes, Taiwan's year-end elections face slower counting and a likely fight over the validity of the results.
