日本卷證不併送制度之配套措施，而訴因制度為卷證不併送之一環，訴因 所要處理之範圍，包括訴因變更、追加、撤回及其他訴因之理論、違反之法律 效果等規定，故卷證不併送本身，顯然不單僅止於「卷證不併送」之意義。其 次，日本法制雖以採卷證不併送為原則，然例外亦有不適用卷證不併送之特殊 程序，可見在採取卷證不併送之制度下，仍有其他配套措施存在。因此，在作 比較法研究時，即有必要以概觀之方式進行研究，以避免發生法律制定後，欠 缺配套措施而造成體系之內在矛盾或衝突。

The Principle of Unitary Information forms a complete set of preventive measures in Japan. However, as a part of unitary information, count system covers a broad range of law proceedings, such as the count changes, additional supplements, withdrawal, law theories based on count system as well as any effects on law violation. Therefore, the Principle of Unitary Information itself obviously has more than the meaning of unitary information. In addition, although Japan's law system adopts the principle, the exceptional cases also triggered special procedures unavailable to fit unitary information. Under the circumstances, other measures need to exist to deal with particular conditions so that when doing research, especially on comparison laws, the researchers require broader views to carry out law studies. As a result, lack of necessary measures may cause contradiction or even irreconcilable conflicts within a legal system.
