The particular issues have been discussed in the present article are very important as well and the decision should be taken will be related not only to the proper implementation of the Directive on consumer ADR (especially due to the reason that the issues discussed in the present article are not unambiguously described in the directive) but to the effectiveness of the national ADR system as well.
