The effects of crossing borders can be advantageous or disadvantageous for the persons concerned; these are all part of the game and cannot be challenged on the basis of EU law. After all, the Treaty on the Functioning of the European Union (TFEU) does not provide powers for harmonisation, but only for coordination. However, the coordination rules themselves may make a person worse off when he or she makes use of the right to free movement. More precisely, such an effect may occur in combination with differences between national systems to which coordination rules are applied. One example is that the coordination rules provide that a person is subject to unemployment benefits in the country of residence and, as a result, if that person becomes ill, also to sickness benefit in that country. If the duration of sickness benefit in the country of residence is 52 weeks, but the waiting period for disability benefit (supposing, for instance, that this is (mainly) due from the country of employment) is 104 weeks, there is a gap of 52 weeks in protection. The relevance of such gaps is not to solve particular cases as such; after all, these are closely linked to particular national systems. The relevance lies in the more general approach that is now being developed by the Court of Justice to address such gaps. This will be useful in cases other than those discussed here and may be further developed in order to be codified in the Coordination Regulation.

差距在移动个人的社会安全保护：选择填补这些空白

跨越国界可为有关人士有利或不利的影响; 这些都是比赛的一部分，不能被欧盟法律的基础上，提出质疑。毕竟，条约，欧洲联盟运作（TFEU）不提供统一的权力，但仅限于协调。然而，协调规则本身可以让一个人更坏时，他或她利用了自由迁徙的权利。更精确地，可以与所应用于协调规则国家系统之间的差异的组合产生这样的效果。一个例子是，协调规则规定一个人在居住国领取失业救济金，因此，如果该人生病，也可以在该国领取疾病补助金。如果在居住国的疾病津贴的时间为52周，但对残疾津贴的等待期（如果，比方，这是（主要）是由于就业的国家）为104周，存在的差距52周的保护。这样的间隙的相关性不是解决特定情况下这样; 毕竟，这是密切相关的特定的国家制度。相关性就在于更普遍的做法，现在正由欧洲法院为解决这些差距。这将在此处讨论的情况以外的情况下有用，并且可能会进一步发展以编入协调条例。有52周在保护的空白。这样的间隙的相关性不是解决特定情况下这样; 毕竟，这些都与特定的国家制度密切相关。相关性就在于更普遍的做法，现在正由欧洲法院为解决这些差距。这将是比这里讨论的情况下非常有用，并且可以为了进一步发展的协调规例进行编纂。有52周在保护的空白。这样的间隙的相关性不是解决特定情况下这样; 毕竟，这是密切相关的特定的国家制度。相关性就在于更普遍的做法，现在正由欧洲法院为解决这些差距。这将是比这里讨论的情况下非常有用，并且可以为了进一步发展的协调规例进行编纂。
