共同环境侵权行为所致的环境污染已成为突出问题,其中因果关系的认定在共同环境侵权理论与司法实践中具有重要的地位和作用,但我国立法上仅仅为环境侵权设置了举证责任倒置原则,还未明确规定因果关系推定原则,因而司法实践上存在着对因果关系认定方式的不同理解和运用,难以应对日益复杂的共同环境侵权诉讼。共同环境侵权具有的特殊特征,需要我们在传统因果关系理论的基础上,通过创新找到合适的因果关系理论来指导司法实践。因此,本文结合实践在共同环境侵权相关理论的基础上,分析了我国共同环境侵权因果关系的立法、司法现状及缺陷,提出了相应的建议。 Environmental pollution caused by common environmental tort has become a prominent issue, of which causal relationship recognition plays an important role and role in the common environmental tort theory and judicial practice. However, the legislation of our country only sets up the principle of reversal of the burden of proof for environmental tort, The principle of presumption of causation has not been defined yet. Therefore, there is a different comprehension and application of the causal relationship determination in judicial practice, which makes it difficult to cope with the increasingly complicated common environmental infringement litigation. The special features of common environmental infringement require us to guide the judicial practice by finding a suitable causal theory based on the traditional theory of causation. Therefore, based on the theory of common environmental infringement, this paper analyzes the legislative and judicial status and defects of the causation of common environmental infringement in our country and puts forward corresponding suggestions.
