In Privacy International and Quadrature Du Net, the Grand Chamber of the CJEU ruled that the e-Privacy Directive generally prevents bulk retention and transmission of traffic and location data, unless Member States can prove serious threats to national security. In such cases, bulk data can be retained during a strictly necessary period, subject to review by a court or independent administrative body. The judgments will impact other data retention and sharing arrangements, such as the PNR, proposed e-Privacy Regulation and e-Evidence package, and adequacy decisions under GDPR, including for post-Brexit UK. The rulings suggest the CJEU's significance in national security, which has been outside of European integration, but has become a ground for political struggle between EU institutions and Member States. While Privacy International unequivocally asserts CJEU's authority in national security and is a victory for data protection, Quadrature Du Net does not oppose indiscriminate data retention in principle and is an ambivalent response to political pressure.

能力之争：国家安全、监督和欧盟法院的欧盟法律范围

In Privacy International和Quadrature Du Net，CJEU 大法庭裁定，电子隐私指令通常会阻止大量保留和传输交通和位置数据，除非成员国能够证明对国家安全构成严重威胁。在这种情况下，可以在绝对必要的时间内保留大量数据，但须接受法院或独立行政机构的审查。这些判断将影响其他数据保留和共享安排，例如 PNR、拟议的电子隐私法规和电子证据包，以及 GDPR 下的充分性决定，包括英国脱欧后的决定。裁决表明欧洲法院在国家安全方面的重要性，它一直在欧洲一体化之外，但已成为欧盟机构与成员国之间政治斗争的基础。虽然隐私国际Quadrature Du Net明确主张欧洲法院在国家安全方面的权威，是数据保护的胜利，Quadrature Du Net原则上不反对滥用数据保留，是对政治压力的矛盾回应。
