1. The Authority shall take the measures referred to in paragraph 2 of this Article only in exceptional circumstances when it considers that the application of one of the legislative acts referred to in Article 1(2), or of any delegated or implementing acts based on those legislative acts, is liable to raise significant issues, for one of the following reasons:

(a) the Authority considers that provisions contained in such act may directly conflict with another relevant act;

(b) where the act is one of the legislative acts referred to in Article 1(2), the absence of delegated or implementing acts that would complement or specify the act in question would raise legitimate doubts concerning the legal consequences flowing from the legislative act or its proper application,

(c) the absence of guidelines and recommendations as referred to in Article 16 would raise practical difficulties concerning the application of the relevant legislative act.
