證據與待證的主要事實之間的聯系有直接也有間接,這構成了區分直接證據與間接證據的客觀基礎。主要事實是與法律要件相當的具體的生活事實,判斷、檢驗是否存在直接證據的標準和依據在于是否存在可以直接證明主要事實的證據。在民事訴訟實務中,一些證據可以用來直接證明主要事實,甚至一個直接證據可以單獨證明主要事實的存在與否,因而直接證據是真實存在的。區分直接與間接證據時,采用單一的分類標準,即只是把能否直接證明主要事實作為區分這兩種證據的標準,比采用直接、單獨雙重分類標準更為可取。

Evidence and the facts to be proved are directly or indirectly associated,which constitutes the objective basis to differentiate direct evidence and indirect evidence.The main facts mean the detailed daily facts equivalent to the legal components,and to judge whether one piece of evidence constitutes direct evidence depends on whether it could directly prove the main facts.In the practice of civil litigations,some evidence could be used to directly prove the main facts,and sometimes,even one single evidence could decide whether the main facts of a case exist or not.Consequently,we may conclude that direct evidence really exists.When we differentiate evidence,I personally believe that adopting the single classification standard is much better than adopting the direct and single double classification standard,which means whether a piece of evidence is direct evidence only depends on whether it could prove the main facts of a case.
