In accordance with the case law of the Court of Justice of the European Union, modifications to a public contract are to be strictly limited to what is absolutely necessary in the circumstances, while complying to the maximum extent possible with the principles of non-discrimination, transparency and proportionality. In that regard, it should be possible to derogate from Directive 2009/81/EC by increasing the quantities provided for in a framework agreement by up to 100 % of the value of that framework agreement when opening it to contracting authorities of other Member States, in so far as such increase is strictly necessary for the opening of the framework agreement to those contracting authorities. With respect to those additional quantities, those contracting authorities should enjoy the same conditions as the original contracting authority that concluded the original framework agreement. In addition, appropriate transparency measures should be taken to ensure that all potentially interested parties are informed.
