Taiwan's political standoff between the executive and the legislature is deepening, a negative sign for anyone hoping the island's government can function smoothly.

• Legislative speaker Han Kuo-yu warned that repeatedly refusing to countersign or carry out passed laws will shake the constitutional order.
• The Executive Yuan fired back that blocking unconstitutional bills is its duty, not an abuse of power.
• Premier Cho Jung-tai is using a constitutional clause that gives him countersigning authority over laws.
• The cabinet says asking lawmakers to reconsider a bill, or refusing to sign it, are both tools the constitution gives it.

Outlook: With neither side backing down, more bills passed by the legislature are likely to stall before taking effect.
