1. Member States shall ensure that a contract is considered ineffective by a review body independent of the contracting authority or that its ineffectiveness is the result of a decision of such a review body in any of the following cases:

(a) if the contracting authority has awarded a contract without prior publication of a contract notice in the Official Journal of the European Union without this being permissible in accordance with Directive 2014/24/EU or Directive 2014/23/EU

(b) in case of an infringement of Article 1(5), Article 2(3) or Article 2a(2) of this Directive, if this infringement has deprived the tenderer applying for review of the possibility to pursue pre-contractual remedies where such an infringement is combined with an infringement of Directive 2014/24/EU or Directive 2014/23/EU, if that infringement has affected the chances of the tenderer applying for a review to obtain the contract;

(c) in the cases referred to in the second subparagraph of Article 2b(c) of this Directive, if Member States have invoked the derogation from the standstill period for contracts based on a framework agreement and a dynamic purchasing system.

2. The consequences of a contract being considered ineffective shall be provided for by national law.
