The principle of mutual trust constitutes a vital parameter for integration within the EU. In allowing Member States to open up to each other despite their legal diversities, this principle is an attractive tool in governance for achieving a borderless European area without going through the unification of the various national laws. The analysis of the consequences of mutual trust in the internal market and in the AFSJ shows that it enables Member States to exercise, to a certain degree, their prescriptive and enforcement powers extraterritorially throughout the whole European area. While the objective of enabling integration without jeopardising national autonomy is beyond doubt legitimate, this trust‐based governance raises several challenges. Integration by means of mutual trust may be problematic with regard to concerns such as national sovereignty, democratic legitimacy, the protection of individual prerogatives, state liability and the duty of public authorities to protect the public interest.

欧盟基于信任的治理所面临的挑战：评估将相互信任作为欧盟一体化的推动力

互信原则是欧盟内部一体化的重要参数。尽管允许会员国在法律上有所不同，但它们彼此开放，这是在实现无边界欧洲地区而不需统一各国法律的情况下进行治理的一种有吸引力的工具。对内部市场和AFSJ中相互信任的后果的分析表明，这使成员国能够在一定程度上在整个欧洲地区域外行使其规定和执行权。尽管毫无疑问实现融合而不损害民族自治的目标是合理的，但这种基于信任的治理带来了一些挑战。
