Yet national and international case law recognizes that a non-discriminatory measure in theory can be discriminatory in practice. So, in the current case, the alleged discrimination does not stem from the law itself, but from its effects, with the plaintiffs relying mainly on statistics showing the over-representation of Roma in special schools.
待遇的不同本身并不是歧视。根据各国最高法院及欧洲人权法院的判例法，只有在处于类似情况中的人被区别对待的时侯方才存在歧视。然而各国及国际判例法也确认，理论上的非歧视措施可能成为实践中的歧视。因此，在当前案例中，所指控的歧视并非根源于法律本身，而是根源于其影响，原告主要根据数据表明特殊学校中罗姆人过多。
