Outline：
The most significant revolution in the amendatory civil procedure in 2000 was the adoption of system of concentrated trial. For getting rid of the disadvantage of principles of consolidation trial and pleading in free time, we adopt principle of concentrated trial and pleading in the due time, which mean that the court must divide the trial into procedures of issue-joinder and evidence-investigation for systematic trial, and parties must make pleadings in the due time, comply with progresses of trial, and fulfill their obligation to assist in a fluent trial. Moreover, for broadening the function of actions to resolution of disputes, we adopt the principle of concentration of disputes and loose the restriction on the change of actions, addition of actions, and counterclaim in court of first instance and appeal. What’s the foundation for adopting these principles? While it has been almost 10 years since the effective date of the amendment, we should consider questions above.
